IMAGE PICKUP APPARATUS, IMAGE PICKUP METHOD, AND PROGRAM THEREFOR |
摘要 |
An image pickup apparatus includes an image pickup unit selectively performing an image capturing operation in a normal image capturing mode where an exposure image signal is output in a unit period and a combined image capturing mode where long- and short-exposure image signals are output in the unit period; a signal processing unit generating a combined image signal with a dynamic range wider than that of the long-exposure image signal or the short-exposure image signal by combining the long-exposure image signal and the short-exposure image signal; a detection unit generating a luminance integrated value of the combined image signal; and a control unit performing exposure correction control using the luminance integrated value. The control unit initializes a correction value used in the exposure correction control when the mode is switched from the normal image capturing mode to the combined image capturing mode.
