Background

In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The following describes in detail an exposure method of an image provided by an embodiment of the present application with reference to the accompanying drawings.
The embodiment of the application provides an image exposure method, which is applied to electronic equipment, wherein the electronic equipment comprises a target sensor, the target sensor is an N-pixel-in-one sensor, and N is an integer greater than 1; fig. 3 is a flowchart of an image exposure method according to an embodiment of the present application, and as shown in fig. 3, the method includes the steps of:
Through step 302 and step 308 of the embodiment of the application, pixel points of the target sensor are divided into N groups, in the process of exposing a first group of pixel points, exposure of a second group of pixel points is started or stopped, namely, the step-type exposure of the first group of pixel points and the second group of pixel points is realized, namely, after the first group of pixel points are exposed, exposure of the second group of pixel points can be started or stopped, exposure processing of the second group of pixel points is not required to be carried out after exposure of the previous group of pixel points, and then the exposed first image and second image are output, so that the frame rate of the output image is improved, and the problem that the frame rate of the output image cannot be further improved due to the fact that the working mode of the mosaic rearrangement sensor in the prior art can only support the high frame rate or the high frame rate.
It should be noted that the target sensor in this embodiment of the present application may be a mosaic rearrangement sensor, and the value of N in this embodiment of the present application may be 4 or 9, that is, the target sensor is a 4-pixel integrated sensor, or a 9-pixel integrated sensor. Taking the target sensor as a 4-pixel-in-one sensor as an example, the pixel points of the target sensor can be divided into 4 groups, based on the above steps 302 to 308, the first image and the second image are obtained through the step-type exposure, and it is not necessary to expose the next group of pixel points to obtain the corresponding image after the previous group of pixel points are completely exposed, which is equivalent to reaching the 2-time frame rate of the sensor in the prior art, if the subsequent two groups of pixel points are continuously exposed, all 4 groups of pixel points are exposed, and the corresponding 4 images are obtained, so that the 4-time frame rate in the prior art is reached, and the frame rate is improved.
In an optional implementation manner in this embodiment, the exposure durations of the first group of pixels corresponding to the first image and the second group of pixels corresponding to the second image are the same and are both target exposure durations, and if a third image is added to the subsequent image until the mth image, the exposure durations of the pixels corresponding to each image are all equal, for example, the target exposure durations are both.
In another optional implementation manner of the embodiment of the present application, regarding the manner involved in step 304 and step 306, the method may specifically include: aiming at M groups of pixel points in the N groups of pixel points, exposing one group of pixel points at intervals of preset time;
the single exposure time of each group of pixel points in the M groups of pixel points is the target exposure time, and the preset time is less than the target exposure time.
In this regard, if the original frame rate of the object sensor is 30fps, the target exposure time length per frame is 33ms, and if the original frame rate of the object sensor is 40fps, the target exposure time length per frame is 25 ms. Based on this, the preset time period should be less than 33ms, or 25 ms.
It should be noted that the preset durations among different pixel point groups may be the same or different. For example, in the case of a target sensor being a 4-pixel-in-one sensor, and the original frame rate of the target sensor being 30fps, the pixels of the target sensor can be divided into 4 groups, the preset duration of the interval between the first group of pixels and the second group of pixels may be 8ms, the preset duration of the interval between the second group of pixels and the third group of pixels may be 8ms, the preset duration of the interval between the third group of pixels and the fourth group of pixels may be 8ms, that is, the preset time intervals between every two adjacent groups are the same, and of course, may be different in other application scenarios, for example, the preset time interval between the first group of pixels and the second group of pixels may be 8ms, the preset time interval between the second group of pixels and the third group of pixels may be 10ms, and the preset time interval between the third group of pixels and the fourth group of pixels may be 6 ms. The specific preset duration can be set according to specific conditions on the premise that the preset duration is less than the target exposure duration, and specific values of the preset duration are not limited in the application.
In an optional implementation manner of the embodiment of the present application, regarding the manner of dividing the pixel points of the target sensor into N groups in step 302 mentioned in the embodiment of the present application, taking the pixel points as the pixel points of three primary colors as an example, further may include:
step 302-11, determining three primary color pixel points in the pixel points to be output, and determining the number of groups;
and step 302-12, grouping the three-primary-color pixel points in the pixel points to be output according to the number of the groups, wherein each group of the pixel points comprises the three-primary-color pixel points, and the number of the three-primary-color pixel points in each group of the pixel points is consistent.
For the above steps 302-11 and 302-12, taking the number of the pixels to be output as 16 and grouping as 4 groups as an example, each group of pixels is 4, each group includes pixels of three primary colors of RGB, and the minimum combination unit (1R, 2G, 1B) constitutes the pixels of the group, and the number of the pixels of each group is also the same, as shown in fig. 4, 16 pixels are labeled first, that is, R0, R1, R2, R3, G0, G1, G2, G3, G '0, G' 1, G '2, G' 3, B0, B1, B2, and B3. After 4 groups are (R0, G0, G '0, B0), (R1, G1, G' 1, B1), (R2, G2, G '2, B2), (R3, G3, G' 3, B3).
The number of the above-mentioned pixels is merely an example, and other numbers of pixels may be grouped, for example, 64M, or 16M for each group if the number of the pixels is 4 groups.
In addition, the preset time length in the embodiment of the present application is a result of rounding a ratio of the target exposure time length to the grouped number N, in this case, M is equal to N, and the target exposure time length is determined by the frame rate of the target sensor. In the case where the target exposure time period is 33ms, the preset time period is the rounded result of 33/4, that is, the preset time period is 8. In the case where the target exposure time period is 25ms, the preset time period is the rounded result of 33/4, i.e., the preset time period is 6. Taking the exposure time of each frame as 33ms, and the preset time is 8ms as an example, as shown in fig. 5, the first group of pixels (R0, G0, G '0, B0) starts exposure at time 0, the corresponding image is output at time 33ms, the second group of pixels (R1, G1, G' 1, B1) starts exposure at time 8ms, the corresponding image is output at time 41ms, the third group of pixels (R2, G2, G '2, B2) starts exposure at time 16ms, the corresponding image is output at time 49ms, the fourth group of pixels (R3, G3, G' 3, B3) starts exposure at time 24ms, and the corresponding image is output at time 57 ms. Namely, 4 images of four groups of pixel points can be obtained at the moment of 57ms, and only one image can be obtained in 57ms for the sensor in the prior art, namely, the frame rate is increased by 4 times by the image exposure method, namely 120 fps.
In an optional implementation manner of the embodiment of the present application, starting or stopping exposure of the second group of pixel points in the process of exposing the first group of pixel points, which is related in step 304, specifically includes: in the process of exposing the first group of pixel points, starting the exposure of the second group of pixel points;
based on this, the method of the embodiment of the present application may further include: step 310, at the second moment, stopping the exposure of the first group of pixel points and the second group of pixel points;
and after determining the first image and the second image, the method of an embodiment of the present application further comprises: step 312, the first image and the second image are synthesized to obtain the target image.
As can be seen from the foregoing steps 304 to 312, in the embodiment of the present application, the exposure start time of each group of pixels is different, and the exposure end time of each group of pixels is the same.
It should be noted that, in the embodiment of the present application, other groups of pixel points in the subsequent N groups of pixel points may also be continuously exposed, the starting time of the subsequent exposure is different from the previous starting time of the subsequent exposure, but the ending time of the subsequent exposure is the same, and the number of the pixel point groups that are exposed most is N. That is to say, in the process of exposing the second group of pixel points, the exposure of the third group of pixel points is started or stopped until the exposure of the Mth group of pixel points is started or stopped, wherein M is more than or equal to 3 and is less than or equal to N. On the basis, the exposure of the M +1 th group of pixel points can be started or stopped in the process of exposing the M-th group of pixel points until the exposure of the N-th group of pixel points is started or stopped.
Further, after the pixel point groups are exposed, corresponding images are obtained, and the obtained images can be synthesized, so that a High-Dynamic Range (HDR) effect can be achieved.
In another optional implementation manner of the embodiment of the present application, the method of the embodiment of the present application further includes: step 314, at the first moment, exposure is started to the second group of pixel points;
based on this, in the process of exposing the first group of pixels involved in step 304 of the present application, the exposure of the second group of pixels is started or stopped, specifically including: stopping the exposure of the second group of pixel points in the process of exposing the first group of pixel points;
based on this, after determining the first image and the second image, the method of the embodiment of the present application further includes: and step 316, synthesizing the first image and the second image to obtain a target image.
As can be seen from the above steps 314 to 316, in the embodiment of the present application, the exposure start time of each group of pixels is the same, and the exposure end time of each group of pixels is different.
It should be noted that, in the embodiment of the present application, other groups of pixel points in the subsequent N groups of pixel points may also be continuously exposed, the starting time of the subsequent exposure is the same as the previous starting time of the subsequent exposure, but the ending time of the subsequent exposure is different, and the number of the pixel point groups that are exposed most is N. That is to say, in the process of exposing the second group of pixel points, the exposure of the third group of pixel points is started or stopped until the exposure of the Mth group of pixel points is started or stopped, wherein M is more than or equal to 3 and is less than or equal to N. On the basis, the exposure of the M +1 th group of pixel points can be started or stopped in the process of exposing the M-th group of pixel points until the exposure of the N-th group of pixel points is started or stopped. Further, after the pixel point groups are exposed, corresponding images are obtained, and the obtained images can be synthesized, so that a High-Dynamic Range (HDR) effect can be achieved.
Taking the above fig. 4 as an example, the grouping number of the pixels is 4, the exposed pixel groups are also 4, the exposure starting time of the 4 groups of pixels is different, and the exposure ending time is the same, for example, the grouped 4 groups of pixels are: (R0, G0, G '0, B0), (R1, G1, G' 1, B1), (R2, G2, G '2, B2), (R3, G3, G' 3, B3). The first group of pixel points (R0, G0, G' 0, B0) start exposure at the time of 0, and the exposure time is set to be 33 ms; the second group of pixel points (R1, G1, G '1, B1) and the third group of pixel points (R2, G2, G' 2, B2) start exposure at the time of 8ms, and the exposure time is set to be 25 ms; the fourth group of pixel points (R3, G3, G' 3, B3) starts exposure at 16ms and sets the exposure time to 17 ms. As shown in fig. 6, 4 images, i.e., overexposure, normal exposure, and underexposure, can be obtained at 33 ms; and then, the four images are synthesized to achieve the effect of a High-Dynamic Range (HDR) image.
It should be noted that the setting of the exposure duration is only an example, as long as all the grouped pixels are exposed within the exposure duration of each frame of image corresponding to the target sensor, for example, the first group of pixels (R0, G0, G' 0, B0) start to be exposed at time 0, and the exposure time is set to be 33 ms; the second group of pixel points (R1, G1, G '1, B1) and the third group of pixel points (R2, G2, G' 2, B2) start exposure at the moment of 6ms, and the exposure time is set to be 27 ms; the fourth group of pixel points (R3, G3, G' 3, B3) starts exposure at 18ms, and the target exposure time is set to 15 ms.
Therefore, through the embodiment of the application, on the premise that the frame rate is not influenced, the pixel points of the sensor are grouped, and then step-type exposure is carried out on each group of pixel points. The images are output at fixed time, multiple groups of images with different exposures can be obtained, and then the multiple groups of images are synthesized, so that the HDR effect is achieved.
