PROBLEM TO BE SOLVED: To provide images which facilitate comparative observation between plural video images captured in plural imaging ranges of an eyeground, to thereby assist in performing suitable diagnosis.SOLUTION: An image display apparatus acquires plural video images captured by imaging plural imaging ranges of an eyeground and time-phase data based on a biological signal at the capturing of each of the plural video images, and displays at least one frame of each of the plural video images at a display timing synchronized based on the time-phase data. The image display apparatus determines, in each of the plural video images, exception frames based on the image features of each of plural frames, and selects sections to be played back in synchronization from the plural video images such that the display of the exception frames is suppressed.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT
