 光学アダプタAを挿入部21に装着し、ストッパ73に当て止めされるまで挿入部21を挿入孔72に挿入する(図9)。ユーザが操作部11を介して検査処理開始の指示入力をすると、制御部61は、メモリ63から判定部64のプログラムを読み込んで実行し、検査処理が開始される。 The optical adapter A is attached to the insertion portion 21, and the insertion portion 21 is inserted into the insertion hole 72 until it is held against the stopper 73 (FIG. 9). When the user inputs an instruction to start the inspection process via the operation unit 11, the control unit 61 reads the program of the determination unit 64 from the memory 63 and executes the program, and the inspection process is started.
 制御部61は、装着された光学アダプタAが、例えば、近点観察用又は遠点観察用のいずれであるか、また、計測用であるか否か等、光学アダプタAの種類をユーザに指示入力させる。 The control unit 61 instructs the user the type of the optical adapter A, such as whether the mounted optical adapter A is for near point observation or far point observation, or whether it is for measurement, for example. Let me input.
 図6に示すように、第1及び第2のターレット83、84を観察孔C1にセットする(S1)。制御部61は、モータ83b、84bの各々に対して第1及び第2のターレット83、84を回動させるための制御信号を出力し、第1及び第2のターレット83、84の各々の観察孔C1を光学アダプタAに対向するように配置させる(図10)。これにより、照明部23は、光検出部82に照明光を照射できるようになる。 As shown in FIG. 6, the first and second turrets 83 and 84 are set in the observation hole C1 (S1). The control unit 61 outputs a control signal for rotating the first and second turrets 83 and 84 to each of the motors 83 b and 84 b, and observes each of the first and second turrets 83 and 84. The hole C1 is disposed to face the optical adapter A (FIG. 10). Thereby, the illumination unit 23 can emit the illumination light to the light detection unit 82.
 照明部23を発光させる(S2)。制御部61は、光源14に対し、光源14を駆動させるための制御信号を出力する。制御信号が入力されると、光源14は、照明光をライトガイドGに出力する。照明部23は、照明窓A2を介し、ライトガイドGから導光された照明光を光検出部82に照射する。 The illumination unit 23 emits light (S2). The control unit 61 outputs a control signal for driving the light source 14 to the light source 14. When the control signal is input, the light source 14 outputs illumination light to the light guide G. The illumination unit 23 illuminates the light detection unit 82 with the illumination light guided from the light guide G through the illumination window A2.
 輝度値が所定範囲であるか否かを検出する(S3)。照明光が照射されると、光検出部82は、輝度値を含む検出信号を制御部61に出力する。制御部61は、光検出部82から入力される輝度値が、メモリ63に記憶された輝度値の所定範囲内であるか否かを判定する。輝度値が所定範囲内であると、制御部61が判定するとき、処理はS6に進む。一方、輝度値が所定範囲内ではないと、制御部61が判定するとき、処理はS4に進む。 It is detected whether the luminance value is within a predetermined range (S3). When the illumination light is irradiated, the light detection unit 82 outputs a detection signal including the luminance value to the control unit 61. The control unit 61 determines whether the luminance value input from the light detection unit 82 is within a predetermined range of the luminance values stored in the memory 63. When the control unit 61 determines that the luminance value is within the predetermined range, the process proceeds to S6. On the other hand, when the controller 61 determines that the luminance value is not within the predetermined range, the process proceeds to S4.
 輝度値の所定範囲は、例えば、製造時の輝度値の計測値の上下5%の範囲内等の範囲に予め設定される。 The predetermined range of the luminance value is, for example, set in advance within a range of 5% above and below the measured value of the luminance value at the time of manufacture.
 S4では、警告メッセージの表示をする。制御部61は、警告メッセージを表示部51に表示させ、ユーザに対し、光学アダプタAの装着状態が異常であることを知らせ、検査処理を終了するか否かの指示入力を促す。 In S4, a warning message is displayed. The control unit 61 displays a warning message on the display unit 51, informs the user that the mounting state of the optical adapter A is abnormal, and prompts the user to input an instruction as to whether or not to end the inspection process.
 検査処理を終了するか否か判定する(S5)。S4において、検査処理を終了するための指示入力があるとき(S5:YES)、処理は終了する。一方、検査処理を継続するための指示入力があるとき(S5:NO)、処理はS6に進む。なお、S4の処理が、例えば、10回等、所定回数以上行われるとき、ユーザに対し、光源14又はライトガイドGの故障の可能性を知らせるための警告メッセージを表示部51に表示させてもよい。 It is determined whether to end the inspection process (S5). When there is an instruction input for ending the inspection process in S4 (S5: YES), the process ends. On the other hand, when there is an instruction input for continuing the inspection process (S5: NO), the process proceeds to S6. When the process of S4 is performed a predetermined number of times such as ten times or more, a warning message may be displayed on the display unit 51 to notify the user of the possibility of the failure of the light source 14 or the light guide G. Good.
 S6では、近点観察用又は遠点観察用のどちらの光学アダプタAの検査処理をするかを判定する。ユーザの指示入力に基づき、装着された光学アダプタAが近点観察用であるとき(S6:近点観察)、処理はS7に進む。一方、装着された光学アダプタAが遠点観察用であるとき(S6:遠点観察)、処理はS8に進む。 In S6, it is determined which of the optical adapter A for near point observation or far point observation is to be inspected. When the mounted optical adapter A is for near point observation (S6: near point observation) based on the user's instruction input, the process proceeds to S7. On the other hand, when the mounted optical adapter A is for far-point observation (S6: far-point observation), the process proceeds to S8.
 続いて、近点観察用の光学アダプタAの検査処理について説明をする。 Subsequently, an inspection process of the optical adapter A for near point observation will be described.
 図7に示すように、S7では、計測用の光学アダプタAの検査処理をするか否かを判定する。ユーザの指示入力の結果に基づき、装着された光学アダプタAが計測用の光学アダプタAであるとき(S7:YES)、処理はS11に進む。一方、装着された光学アダプタAが計測用の光学アダプタAではないとき(S7:NO)、処理はS21に進む。 As shown in FIG. 7, in S7, it is determined whether the inspection process of the optical adapter A for measurement is to be performed. When the mounted optical adapter A is the measurement optical adapter A based on the result of the user's instruction input (S7: YES), the process proceeds to S11. On the other hand, when the mounted optical adapter A is not the measurement optical adapter A (S7: NO), the process proceeds to S21.
 S11では、第1のターレット83を計測チャートC3にセットする。制御部61は、第1のターレット83を計測チャートC3にセットするための制御信号をモータ83bに出力し、計測チャートC3が光学アダプタAに対向するように、第1のターレット83を回動させる。 At S11, the first turret 83 is set to the measurement chart C3. The control unit 61 outputs a control signal for setting the first turret 83 to the measurement chart C3 to the motor 83b, and rotates the first turret 83 so that the measurement chart C3 faces the optical adapter A. .
 計測チャートC3を計測する(S12)。制御部61は、撮像部24を駆動させ、観察窓A3を介して撮像部24に被写体像を取得させる。撮像部24には、計測用の光学アダプタAにより、互いに視差を有する右眼用及び左眼用の被写体像が投影される。撮像部24は、右眼用及び左眼用の被写体像を撮像信号に変換し、画像処理部41に出力する。画像処理部41は、撮像部24から入力される撮像信号に基づいて、所定の画像処理をし、右眼用画像及び左眼用画像を制御部61に出力する。制御部61は、右眼用画像及び左眼用画像の各々に基づいて、2点間距離D3を所定の演算処理によって算出する。これにより、内視鏡装置1では、光学アダプタAを介し、計測チャートC3上の2点間距離D3が計測される。 The measurement chart C3 is measured (S12). The control unit 61 drives the imaging unit 24 and causes the imaging unit 24 to acquire a subject image through the observation window A3. On the imaging unit 24, subject images for the right eye and for the left eye having parallax with each other are projected by the optical adapter A for measurement. The imaging unit 24 converts subject images for the right eye and the left eye into imaging signals, and outputs the imaging signals to the image processing unit 41. The image processing unit 41 performs predetermined image processing based on the imaging signal input from the imaging unit 24, and outputs the right-eye image and the left-eye image to the control unit 61. The control unit 61 calculates the two-point distance D3 by a predetermined calculation process based on each of the right-eye image and the left-eye image. Thereby, in the endoscope apparatus 1, the distance D3 between two points on the measurement chart C3 is measured via the optical adapter A.
 2点間距離D3が所定範囲内であるか否かを判定する(S13)。制御部61は、S12によって計測した2点間距離D3が、メモリ63に記憶された2点間距離D3の所定範囲であるか否かを判定する。S12によって算出した2点間距離D3が所定範囲内であると、制御部61が判定するとき、処理は終了する(S13:YES)。一方、S12によって算出した2点間距離D3が所定範囲内ではないと、制御部61が判定するとき、処理はS14に進む(S13:NO)。 It is determined whether the distance D3 between two points is within a predetermined range (S13). The control unit 61 determines whether the two-point distance D3 measured at S12 is within the predetermined range of the two-point distance D3 stored in the memory 63. When the control unit 61 determines that the two-point distance D3 calculated in S12 is within the predetermined range, the process ends (S13: YES). On the other hand, when the control unit 61 determines that the two-point distance D3 calculated in S12 is not within the predetermined range, the process proceeds to S14 (S13: NO).
 2点間距離D3の所定範囲は、例えば、製造時における2点間距離D3の算出値の上下5%の範囲内等の範囲に予め設定される。 The predetermined range of the two-point distance D3 is set, for example, in the range of 5% above and below the calculated value of the two-point distance D3 at the time of manufacture.
 S14では、警告メッセージを表示する。制御部61は、2点間距離D3が所定範囲ではないことをユーザに知らせるための警告メッセージを表示部51に表示させる。警告メッセージの表示後、処理は終了する。 In S14, a warning message is displayed. The control unit 61 causes the display unit 51 to display a warning message for notifying the user that the two-point distance D3 is not within the predetermined range. After the warning message is displayed, the process ends.
 S21では、第1のターレット83を解像チャートC2にセットする。制御部61は、第1のターレット83を解像チャートC2にセットするための制御信号をモータ83bに出力し、解像チャートC2が光学アダプタAに対向するように、第1のターレット83を回動させる。 At S21, the first turret 83 is set to the resolution chart C2. The controller 61 outputs a control signal for setting the first turret 83 to the resolution chart C2 to the motor 83b, and rotates the first turret 83 so that the resolution chart C2 faces the optical adapter A. Move it.
 解像チャートC2の画像を取得する(S22)。制御部61は、撮像部24を駆動させ、撮像部24に解像チャートC2の被写体像を取得させる。撮像部24によって取得された被写体像は、画像処理部41を介し、観察画像として制御部61に入力される。 An image of the resolution chart C2 is acquired (S22). The control unit 61 drives the imaging unit 24 to cause the imaging unit 24 to acquire an object image of the resolution chart C2. The subject image acquired by the imaging unit 24 is input to the control unit 61 as an observation image through the image processing unit 41.
 解像度が所定範囲内であるか否かを判定する(S23)。制御部61は、S22によって取得された観察画像と、メモリ63に記憶された基準画像とに対し、パターンマッチング処理をする。観察画像が基準画像と近似するとき、観察画像の解像度が所定範囲内であると制御部61が判定し(S23:YES)、処理は終了する。一方、S22によって取得された観察画像が基準画像に近似しないとき、観察画像の解像度が所定範囲内ではないと、制御部61が判定し(S23:NO)、処理はS24に進む。 It is determined whether the resolution is within a predetermined range (S23). The control unit 61 performs pattern matching processing on the observation image acquired in S22 and the reference image stored in the memory 63. When the observation image approximates the reference image, the control unit 61 determines that the resolution of the observation image is within the predetermined range (S23: YES), and the process ends. On the other hand, when the observation image acquired in S22 does not approximate the reference image, the control unit 61 determines that the resolution of the observation image is not within the predetermined range (S23: NO), and the process proceeds to S24.
 パターンマッチング処理の例として、制御部61は、例えば、観察画像及び基準画像の各々の画素値に基づいて互いの近似の程度を示す特徴量を算出し、特徴量が所定閾値以上であるとき、観察画像の解像度が所定範囲内であると判定し、一方、特徴量が所定閾値未満であるとき、観察画像の解像度が所定範囲内ではないと判定してもよい。 As an example of the pattern matching process, for example, the control unit 61 calculates feature quantities indicating the degree of approximation with each other based on the pixel values of each of the observation image and the reference image, and when the feature quantities are equal to or more than a predetermined threshold value It may be determined that the resolution of the observation image is within the predetermined range, while the resolution of the observation image is not within the predetermined range when the feature amount is less than the predetermined threshold.
 解像度の所定範囲は、例えば、製造時に撮像された解像チャートC2の観察画像である基準画像の解像度の上下5%の範囲内等の範囲に予め設定される。所定閾値は、特徴量及び解像度の所定範囲に応じて予め設定される。 The predetermined range of resolution is set, for example, in the range of 5% above and below the resolution of the reference image which is an observation image of the resolution chart C2 captured at the time of manufacture. The predetermined threshold is preset according to the predetermined range of the feature amount and the resolution.
 なお、パターンマッチング処理は、画素値に基づいて特徴量を算出して行われる方法に限定されるものではない。 The pattern matching process is not limited to the method performed by calculating the feature amount based on the pixel value.
 S24では、警告メッセージを表示する。制御部61は、観察画像の解像度が、所定範囲内ではないことをユーザに知らせるための警告メッセージを表示部51に表示させる。警告メッセージの表示後、処理は終了する。 In S24, a warning message is displayed. The control unit 61 causes the display unit 51 to display a warning message for informing the user that the resolution of the observation image is not within the predetermined range. After the warning message is displayed, the process ends.

When the optical adapter A is the measurement optical adapter A based on the result of the user's instruction input, the process proceeds to S31. On the other hand, when the optical adapter A is not the measurement optical adapter A, the process proceeds to S41.

 2点間距離D3が所定範囲内であるか否かを判定する(S33)。S32によって算出した2点間距離D3が所定範囲内であると、制御部61が判定するとき(S33:YES)、処理は終了する。一方、S32によって算出した2点間距離D3が所定範囲内ではないと、制御部61が判定するとき(S33:NO)、処理はS34に進む。 It is determined whether the distance D3 between two points is within a predetermined range (S33). When the control unit 61 determines that the two-point distance D3 calculated in S32 is within the predetermined range (S33: YES), the process ends. On the other hand, when the controller 61 determines that the two-point distance D3 calculated in S32 is not within the predetermined range (S33: NO), the process proceeds to S34.
 S34では、警告メッセージを表示する。制御部61は、計測結果が、所定範囲内ではないことをユーザに知らせるための警告メッセージを表示部51に表示させる。警告メッセージの表示後、処理は終了する。 In S34, a warning message is displayed.
