- FIG. 21 is a schematic diagram for explaining the operation of setting the display frame rate of the image data of the reproduction part to the low speed setting or the high speed setting and deleting the image data other than the reproduction part.
- the control unit 42 and the frame rate control unit 42b perform the same processing as steps S601 to S605 described above (steps S901 to S905).
- the frame rate control unit 42b sets the display frame rate of the image data to the normal setting with the shift of the low-speed playback mark and the high-speed playback mark in the series of image data of the subject 1 being added (Step S1). S904), the display frame rate of the image data with the low-speed playback mark is changed to this normal setting power (Step S902), and the display frame rate of the image data with the high-speed playback mark is changed to this normal setting power high speed. Change to setting (step S905).
- the control unit 42 determines whether or not a skip mark is added to the image data of the display frame rate of the low speed setting, the high speed setting, or the normal setting (step S906) o control If the unit 42 determines that no skip mark is given to the image data (step S906, No), the display unit 12 is informed of the subject 1 corresponding to the image data. Control is performed to display the image at the display frame rate determined by the frame rate control unit 42b (step S907). On the other hand, when the control unit 42 determines that a skip mark has been added to this image data (step S906, Yes), the frame rate control unit 42b obtains this image data from a series of image data to be displayed. Perform the deletion process. Based on this, the control unit 42 does not display the image data on the display unit 12.

Is not displayed, that is, the image is cut, and the image of the medically abnormal part such as the bleeding part or the lesion part is displayed at low speed in the image of the reproduction part, and this medically abnormal part is displayed. It was configured to display the image of the replayed part except for at high speed. Therefore, when displaying a series of images of a subject, it is possible to easily cut an image other than the observation target region, and forcibly display a medically abnormal portion of the image of the observation target region at a low speed. It is possible to realize an image display apparatus that can enjoy the effects of the third embodiment described above and can easily observe an abnormal part of an organ designated as an observation target.
- the examiner can automatically display only an image of an organ designated as an observation target, for example, an image of the small intestine, among a series of images of the subject.
- an image of a medically abnormal part such as a bleeding part or a lesion part can be automatically displayed at a low speed.
- the examiner can easily observe the medically abnormal region and can observe the organ designated as the observation target using the pseudo moving image. This is useful for examining the condition of the organ in the subject's ability.
- the image display apparatus can display a series of images taken in time series in the digestive tract of a subject, and in particular, a desired observation target site or a medically abnormal site. It is suitable for an image display device that can shorten the time for observing a series of images in a subject without obstructing observation.
