Abstract
According to an embodiment of the present disclosure, a part estimated to have a high degree of generation of false color for predetermined parts of an input image imaged by different exposure times at a predetermined spatial period is detected. A false color intensity value indicating an estimated degree of generation of false color is calculated for each of the predetermined parts. A high dynamic range image is generated by executing processing to merge long-time exposure pixels and short-time exposure pixels making up the input image. False color correction processing is executed according to the intensity of the false color intensity value, to the high dynamic range image. The present disclosure may be applied to, for example, an image processing unit within a solid state image sensor.
