Image capturing apparatus and image capturing method
First Claim
1. An image capturing apparatus having a display device capable of displaying an image, comprising:
- (a) an image capturing device which generates an image of a subject;
(b) a driver which sequentially drives said image capturing device at timings based on a high frame rate higher than a display frame rate used at the time of displaying a moving image on said display device;
(c) an image capturing controller which sequentially captures two or more images while changing an image capturing condition each time said image capturing device is driven by said driver; and
(d) a synthesizer which synthesizes said two or more images, thereby generating a synthetic image, wherein with respect to changing in said image capturing condition by said image capturing controller, said image capturing condition is changed in two or more levels.

Abstract
The image capturing apparatus can perform image capturing at a high frame rate higher than a frame rate used for displaying a moving image. In image capturing with flashlight in the image capturing apparatus, the high frame rate is set and three images are successively captured while increasing the light emission amount of the flashlight in order. A region in the lower portion of the image captured first, a region in the center portion of the image captured second, and a region in the upper portion of the image captured third, the exposure level being proper in each of these regions, are extracted and combined. As a result, a high-quality synthetic image in which exposure is proper from the front side to the deep side in image capturing in a room can be generated.

9. An image capturing method using an image capturing device which generates an image of a subject, the method comprising the steps of:
-
(a) sequentially driving said image capturing device at timings based on a high frame rate higher than a display frame rate used at the time of displaying a moving image on a display;
(b) sequentially capturing two or more images while changing an image capturing condition each time said image capturing device is driven in said step (a); and
(c) synthesizing said two or more images, thereby generating a synthetic image, wherein with respect to changing in said image capturing condition in said step (b), said image capturing condition is changed in two or more levels.
