Patent ID: 7873271

Claim:
A photography apparatus, comprising: imaging means for performing at least two photography operations including a first photography operation and a second photography operation with different photography conditions for a single subject, and obtaining a plurality of image signals corresponding to the plurality of photography operations; light emitting means, for emitting flash toward the subject; image signal processing means, for processing the plurality of image signals; and control means, for controlling the imaging means, the light emitting means, and the image signal processing means such that they perform photography operations according to a standard photography method, comprising the steps of: performing the first photography operation while emitting flash; performing the second photography operation while preventing the flash from being emitted; calculating a flash influence signal value F 1 , which is the amount of influence due to flash emission within an image signal P 1 obtained by the first photography operation; calculating a flash influence signal value F 2 , which is the amount of influence due to flash emission in the case that flash was emitted during the second photography operation, based on the differences between the imaging conditions of the first photography operation and the imaging conditions of the second photography operation and the flash influence signal value F 1 ; and obtaining an image signal P 2 ″, which is an image signal which is estimated to be obtained in the case that flash was emitted during the second photography operation, by adding the flash influence signal value F 2 to an image signal P 2 obtained by the second photography operation.
