An image generation apparatus generates a new video sequence with a high S/N ratio and suppressed motion blurs, from an original video sequence and a still image which are generated by capturing the same dark, moving object. The image generation apparatus includes: a capture condition decision unit (105) which decides, based on an incident-light amount, capture conditions under which the original video sequence and the still image are to be captured; an image receiving unit (101) which receives the original video sequence and the still image which are generated under the capture conditions; an integration processing unit (104a) which generates, from the original video sequence and the still image, the new video sequence including frames having a resolution equal to or higher than the still image, at a frame rate equal to or higher than the original video sequence, by reducing a difference between (i) a value of the still image and (ii) a sum of values of the frames in the new video sequence which correspond to an exposure period for the still image. The capture condition decision unit (105c) decides a longer duration of an exposure period as a duration of the still image capturing, as the incident-light amount is smaller. Here, the duration is longer than an frame interval of the original video sequence. |
