Short exposure time which is combined with a long exposure time in acccordance with a scene change |
摘要 |
An image pickup apparatus includes an image pickup unit configured to output a long-exposure image signal with a relatively long exposure time and a short-exposure image signal with a relatively short exposure time; a signal processing unit configured to generate a combined image signal with a relatively wide dynamic range at least wider than that of the long-exposure image signal or that of the short-exposure image signal by combining the long-exposure image signal and the short-exposure image signal; a detection unit configured to generate a luminance integrated value of the combined image signal; and a control unit configured to perform exposure correction control using the luminance integrated value. The control unit initializes a correction value for use in the exposure correction control during a scene change. |
