Image generation apparatus and image generation method
First Claim
1. An image generation apparatus that generates, from a plurality of video sequences obtained by photographing a same object, a new video sequence which represents the same object, said image generation apparatus comprising:
- an image receiving unit operable to receive a first video sequence including frames having a first resolution and a second video sequence including frames having a second resolution which is higher than the first resolution, each frame of the first video sequence being obtained with a first exposure time, and each frame of the second video sequence being obtained with a second exposure time which is longer than the first exposure time; and
an image integration unit operable to generate, from the first video sequence and the second video sequence, the new video sequence including frames having a resolution which is equal to or higher than the second resolution, at a frame rate which is equal to or higher than a frame rate of the first video sequence, by reducing a difference between a value of each frame of the second video sequence and a sum of values of frames of the new video sequence which are included within an exposure period of a frame of the second video sequence.

Abstract
An image generation apparatus includes an image receiving unit which receives a first video sequence including frames having a first resolution and a second video sequence including frames having a second resolution which is higher than the first resolution. Each frame of the first video sequence is obtained with a first exposure time, and each frame of the second video sequence is obtained with a second exposure time which is longer than the first exposure time. The image generation apparatus also includes an image integration unit which generates, from the first video sequence and the second video sequence, a new video sequence including frames having a resolution which is equal to or higher than the second resolution, at a frame rate which is equal to or higher than a frame rate of the first video sequence. The new video sequence is generated by reducing a difference between a value of each frame of the second video sequence and a sum of values of frames of the new video sequence which are included within an exposure period of the frame of the second video sequence.

11. An image generation method for generating a new video sequence from a plurality of video sequences, said image generation method comprising:
-
receiving a first video sequence including frames having a first resolution and a second video sequence including frames having a second resolution which is higher than the first resolution, each frame of the first video sequence being obtained with a first exposure time, and each frame of the second video sequence being obtained with a second exposure time which is longer than the first exposure time; and generating, from the first video sequence and the second video sequence, the new video sequence including frames having a resolution which is equal to or higher than the second resolution, at a frame rate which is equal to or higher than a frame rate of the first video sequence, by reducing a difference between a value of each frame of the second video sequence and a sum of values of frames of the new video sequence which are included within an exposure period of a frame of the second video sequence.

12. A computer-readable medium having a computer program recorded thereon, said computer program for generating a new video sequence from a plurality of video sequences, said computer program causing a computer to execute:
-
receiving a first video sequence including frames having a first resolution and a second video sequence including frames having a second resolution which is higher than the first resolution, each frame of the first video sequence being obtained with a first exposure time, and each frame of the second video sequence being obtained with a second exposure time which is longer than the first exposure time; and generating, from the first video sequence and the second video sequence, the new video sequence including frames having a resolution which is equal to or higher than the second resolution, at a frame rate which is equal to or higher than a frame rate of the first video sequence, by reducing a difference between a value of each frame of the second video sequence and a sum of values of frames of the new video sequence which are included within an exposure period of a frame of the second video sequence.
