Further, as a transmission medium used in the communication unit 11, for example, an infrared ray such as IrDA or a remote control, Bluetooth (registered trademark), IEEE1394, USB, power line carrier, cable TV line, telephone line, ADSL line, etc. Wireless such as 802.11 wireless, HDR, mobile phone network, satellite line, terrestrial digital network, etc. may be used.

  The memory reading unit 12 is mounted with various detachable recording media (for example, a USB memory, a card memory, etc.) with respect to the image forming apparatus 1, reads an image file from the mounted recording medium, This is transmitted to the determination unit 13.

  The file determination unit 13 determines whether the image file input from the communication unit 11 or the memory reading unit 12 is a moving image file, and outputs the determination result and the image file to the image conversion unit 14.

  The image converting unit (moving image / still image converting unit) 14 converts the moving image data included in the moving image file into still image data and converts the still image file when the file determining unit 13 determines that the moving image file is a moving image file. Generate and output to the data separator 15.

  When the still image file input from the image conversion unit 14 includes caption data, the data separation unit 15 separates the still image data and the caption data included in the still image file. The data is output to the print data generation unit 16. It should be noted that the determination process of whether or not caption data is included in a still image file may be performed by the data separation unit 15, and the determination result may be transmitted to the data separation unit 15 by the file determination unit 13. It may be.

  The print data generation unit 16 expands and combines the still image data and the caption data input from the data separation unit 15 to generate print data. The print data generated by the print data generation unit 16 is temporarily stored in the print data storage unit 17, read at a predetermined timing, and output to the print processing unit 18.

  The print processing unit 18 prints an image corresponding to the print data input from the print data generation unit 16 on a recording material such as paper. The configuration of the print processing unit 18 is not particularly limited, and for example, an electrophotographic printer, an inkjet printer, a sublimation printer, or the like can be used.

  In this embodiment, the image forming apparatus 1 acquires a moving image file generated by another apparatus via the communication unit 11 or the memory reading unit 12, but the present invention is not limited to this. For example, the image forming apparatus 1 itself may have a function of generating a moving image file and a function of printing a still image based on the generated moving image file.

(1-2. Print data generation process)
FIG. 2 is a flowchart showing the flow of print data generation processing in the image forming apparatus 1.

  First, when the communication unit 11 or the memory reading unit 12 acquires an image file (S1), the file determination unit 13 determines whether the acquired image file is a moving image file (S2).

  If the file determination unit 13 determines in S2 that the file is not a moving image file, that is, if it is determined that the file is a still image file, a still image printing process is performed (S3), and the process ends. In the still image printing process, the print data generation unit 16 expands still image data included in the image file, generates print data, and temporarily stores the print data in the print data storage unit 17. The print processing unit 18 prints the print data storage unit 17. Is read out and printed on a recording material such as paper.

  On the other hand, when the file determination unit 13 determines in S2 that the file is a moving image file, the image conversion unit 14 converts the moving image data included in the image file into still image data (S4), and the image file includes still image data. Is output to the data separator 15.

  In the present embodiment, the moving image data is composed of a plurality of still images, and is converted into still image data by extracting (sampling) a still image for each predetermined frame. For example, 30 fps moving image data is composed of 30 still images per second, and one or more still image data corresponding to the moving image data is generated by extracting still images for each one or more frames. It has become. The number of still images to be extracted is arbitrarily set by the user via an operation panel (not shown) provided in the image forming apparatus 1. However, the present invention is not limited to this, for example, depending on the number of still images to be output on one output sheet, the number of frames per second in moving image data, the number of frames in the entire moving image data, the number of output sheets, or a combination thereof Alternatively, the setting condition for the number of extracted frames may be set in advance, and the data separation unit 15 may automatically determine it according to the setting condition.

  When receiving the image file from the image conversion unit 14, the data separation unit 15 determines whether or not caption data is included in the image file (S5).

  When it is determined in S5 that no caption data is included, the data separation unit 15 outputs still image data included in the image file received from the image conversion unit 14 to the print data generation unit 16, and the print data generation unit 16 The still image data received from the data separator 15 is developed on a frame memory (not shown) (S6).

  On the other hand, when it is determined in S5 that the caption data is included, the data separation unit 15 separates the still image data and the caption data included in the image file (S7), and the still image data and the caption data are separated. Is output to the print data generation unit 16.

  For example, in the case of a VOB file that is a moving image file format used in the DVD-video standard, caption data is stored as TIFF image data in the VOB file together with the moving image data. Separate from data.

  The print data generation unit 16 expands the still image data received from the data separation unit 15 on a frame memory (not shown) (S8) and places an image corresponding to the caption data at a predetermined position on the frame memory. Place (layout) (S9).

  After expanding the still images (or still images and subtitles) on the frame memory in S6 or S9, the print data generation unit 16 determines whether the number of still images expanded on the frame memory has reached a predetermined number. Judgment is made (S10). In the present embodiment, an arbitrary number of still images can be arranged and printed on one output sheet in accordance with a user instruction, and the predetermined number is printed on one output sheet. The number of still images is set.

  If it is determined in S10 that the number of still images has not reached the predetermined number (S10), the process returns to S4 and the next still image data is converted.

  On the other hand, if it is determined in S10 that the number of still images has reached a predetermined number, the print data generation unit 16 generates print data corresponding to the image developed on the frame memory and temporarily stores it in the print data storage unit 17. (S11). Thereafter, the print data stored in the print data storage unit 17 is read out to the print processing unit 18 at a predetermined timing, and the print processing unit 18 performs a printing process (S12).

  Thereafter, the file determination unit 13 determines whether or not the printing process is finished (S13). If the printing process is not finished, the process of S4 is continued.

(1-3. Print output example)
FIG. 3 is an explanatory diagram showing an example of moving image data and print output based on the moving image data.

  As shown in the upper part of FIG. 3, in this example, the character image “ABCDEFGH...” Moves from right to left in the moving image data, and “ABCDEFGH” is displayed near the lower end of the screen. The subtitle is displayed. In the print output, a still image for each predetermined frame is extracted from moving image data, and the extracted still image and subtitles are superimposed and printed. In the example of FIG. 3, nine frames of still images are printed on one output sheet.

  Note that the number of still images to be printed on one output sheet may be arbitrarily designated by the user via an operation panel (not shown) provided in the image forming apparatus 1.

  In the example of FIG. 3, still images and subtitles are printed. However, the present invention is not limited to this. For example, (i) both still images and subtitles are printed, and (ii) subtitles without printing still images. The user can select whether to perform only one of the following: (iii) print only still image without printing subtitles (iii) via the operation panel (not shown) provided in the image forming apparatus 1 May be specified.

  Alternatively, the caption data separated from the image file may be converted into text data, and the caption data may be printed out as text data.

  In the example of FIG. 3, the still image and the subtitle are superimposed and arranged, but the present invention is not limited to this. For example, as shown in FIG. 4, the still image and the caption may be arranged so as not to overlap in the vicinity of the still image print area.

  Further, the user can arbitrarily select whether the subtitle is superimposed on the still image or the subtitle is not superimposed on the still image via an operation panel (not shown) provided in the image forming apparatus 1. It may be possible to specify.

  Further, the subtitle arrangement position may be arbitrarily designated by the user via an operation panel (not shown) provided in the image forming apparatus 1. For example, the user can arbitrarily select whether to place in the vicinity of the lower end, the left end, the right end, or the upper end of the still image and whether to superimpose the subtitles on the still image. Also good.

[Embodiment 2]
Another embodiment of the present invention will be described. For convenience of explanation, members having the same functions as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and description thereof is omitted.

  In the first embodiment, the user arbitrarily sets the sampling rate of still images from moving image data (how many still images are extracted every frame). On the other hand, in the present embodiment, as shown in FIG. 5, a still image is extracted at each timing when the subtitles are switched.

  Specifically, in the process of S4 in FIG. 2, the image conversion unit 14 detects the timing at which the content of the subtitle is switched based on the subtitle data included in the image file, and is included in the image data every time the content of the subtitle is switched. Still images are extracted from moving image data. Other processes are the same as those in the first embodiment.

  In general, in the case of a moving image with subtitles, the timing at which subtitles are switched often coincides with the timing at which the content of moving images changes greatly. For this reason, by adopting a configuration in which still images are extracted from a moving image and printed at each timing when subtitles are switched as in the present embodiment, it is possible to extract and print a still image of an appropriate frame from the entire moving image.

  That is, in the case of a moving image frame of 30 fps, there are 30 frames per second, and if all the frames are printed, it will be enormous. Therefore, the user must select which frame to extract and print. Not easy. On the other hand, according to the present embodiment, by extracting and printing a still image at each timing when the subtitles are switched, an appropriate frame is selected according to the content of the moving image from among the enormous still images constituting the moving image. Still images can be easily extracted and printed.

  In the example of FIG. 5 described above, one still image is extracted every time a subtitle is switched. However, the present invention is not limited to this. For example, as illustrated in FIG. A plurality of still images may be extracted per subtitle. In this case, for example, the user may specify the number of still images to be extracted per caption (per caption) via the operation panel (not shown) of the image forming apparatus 1. Thereby, it is possible to easily extract and print a still image having an appropriate number of frames according to the content of the moving image from a large number of still images constituting the moving image.

  When extracting a plurality of still images per caption, for example, in the process of S4 in FIG. 2, the image conversion unit 14 detects a cycle in which the caption is switched based on the caption data included in the image file, The period corresponding to one subtitle may be divided at equal time intervals into the number of still images to be extracted per one subtitle specified by the user, and still images may be extracted every divided time. Other processes are the same as those in the first embodiment.

On the other hand, in the present embodiment, the user can arbitrarily set the size of subtitles printed on the output paper via the operation panel (not shown) of the image forming apparatus 1.

  For example, when the subtitle size and the still image size are printed as set in the input image file, the subtitle size is used when printing a plurality of still images side by side on the output paper as shown in the middle of FIG. Becomes too small to be visually recognized. In such a case, as shown in the lower part of FIG. 7, the print data may be generated by enlarging the caption and combining it with the still image.

  When the number of still images arranged on one output sheet is small, the subtitles may be too conspicuous if the ratio between the subtitle size and the still image size is set in the input image file. In such a case, the print data may be generated by reducing the caption and combining it with the still image.

  In the example of FIG. 7, the subtitles subjected to the scaling process are arranged so as to be superimposed on the still image, but not limited thereto, the subtitles subjected to the scaling process as illustrated in FIG. You may arrange | position in the position which does not overlap. Also, when subtitles are printed with still images superimposed, the ratio of the subtitle size to the still images is not changed. When subtitles are printed without being superimposed with still images, the subtitle size ratio to the still images is not changed. For example, the subtitle size setting may be changed according to conditions.
