CAMERA HAVING IMPROVED IMAGE QUALITY |
摘要 |
Under exposure determination unit 212 determines whether or not there is under exposure during exposure set using a hand vibration time limit. When a suitable exposure time is longer than the hand vibration time limit, the exposure time is increased by increasing the gain set for the hand vibration time limit. When a flash is used, the distance the emitted light of the flash must reach is determined from the flash guide number and open aperture value, and a determination is made as to whether or not the light emitted by the flash will reach the photographic subject. Under exposure is determined when the distance to the photographic subject is longer than the distance attained by the light emitted from the flash, and the gain is adjusted in accordance therewith.
