Abstract:
1. An image generation apparatus that generates a target video sequence in color from a plurality of input video sequences, each input video sequence corresponding to a different color component of a plurality of color components, said image generation apparatus comprising: an image receiving unit configured to receive, as the plurality of input video sequences, a plurality of video sequences obtained by shooting a same subject with a phase difference, such that at least one of (i) exposure start times for the color components corresponding to the received video sequences are different from each other and (ii) exposure end times for the color components corresponding to the received video sequences are different from each other; and an image integration processing unit configured to generate the target video sequence having a frame interval which is shorter than each frame exposure period of the received video sequences, wherein each respective frame exposure period of the frame exposure periods is a period between an exposure start time and a corresponding exposure end time of a frame within a respective received video sequence of the received video sequences, and wherein the target video sequence is generated from the plurality of received video sequences by reducing a sum of a difference, for each of the different color components, between a value of a frame image of one of the frame exposure periods of one of the received video sequences and a sum of values of a plurality of frame images of the target video sequence included in the one frame exposure period of the received video sequence.
