Image pickup apparatus, image pickup method, exposure control method, and program

摘要

An image pickup apparatus includes: an image pickup unit configured to generate a long-exposure image signal and a short-exposure image signal from incident light and output the generated signals as image pickup signals, the long-exposure image signal being generated by exposure for a relatively long period and the short-exposure image signal being generated by exposure for a relatively short period; a signal processing unit configured to generate a combined image signal by combining the long-exposure image signal and the short-exposure image signal, the combined image signal having a dynamic range that is relatively wider than that of at least any one of the long-exposure image signal and the short-exposure image signal; a detection unit configured to obtain a luminance integrated value and a luminance histogram of the combined image signal; and a control unit configured to perform exposure correction control using the luminance integrated value and the luminance histogram.
