Further, when the display control unit 52 determines that the instruction information for instructing the image display of the image group Pa is input (step S103: Yes), the image display control unit 53 controls the display unit 40 with respect to the body cavity. The in-vivo images in the image group Pa are displayed in the inner image display area A1 in the order of frame numbers (step S104).

  Next, the display control unit 52 determines whether an image is designated (step S105). If no image is specified (step S105: No), the display control unit 52 determines whether the final image has been displayed (step S109), and if the image display has not been displayed until the final image (step S109) If NO in step S109, the process returns to step S104 to display an image by the image display control unit 53. If the image display is displayed up to the final image (in the case of YES in step S109), the above-described process is performed. End the operation.

  Further, when the left button of the mouse is double-clicked while the mouse of the input unit 20 is operated and the cursor 21 on the screen is moved onto the body cavity image, the display control unit 52 specifies the image. Judge that it was made. When this image is designated, the reduced image display control unit 56 causes the thumbnail image of the designated image to be displayed in the thumbnail image display area A2 in the order of the frame number (step S106). Then, the scale display control unit 54 performs control so that the time bar 42 is displayed at a predetermined position in the image display area W (step S107). At this time, the scale display control unit 54 sets the distance corresponding to the time on the time bar 42 as the base point at the position corresponding to the imaging time (specified time) of the image specified by the input unit 20. = K√ | x | is defined by a function, and the time bar 42 is controlled to be displayed. Further, the index display control unit 55 performs control so that the index 44 indicating the position corresponding to the imaging time of the image designated by the input unit 20 is displayed at the corresponding position on the time bar 42 (step S108). .

  In step S109, the display control unit 52 determines whether or not the final image is displayed. If the image display is not displayed until the final image (step S109: No), the process returns to step S104. The image display by the image display control unit 53 is performed, and when the image display is displayed up to the final image (step S109: Yes), the above operation is terminated.

  As described above, in this embodiment, the scale display control unit 54 defines the distance corresponding to the time by the function based on the position corresponding to the specified time according to the designation of the image from the input unit 20. Since the display control of the bar 42 is performed, the distance corresponding to a specific range as a specific time zone with the position corresponding to the specified time as a base point is enlarged, and the distance to the time is displayed shorter as the time is further away from the specified time.
