IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM

WIPO Patent Application WO/2016/129405

A1

The present disclosure pertains to an image processing device, an image processing method, and a program with which it is possible to reduce the effect of a flicker during high-dynamic-range (HDR) image-capturing. A flicker detection unit calculates the amplitude and period of a flicker component from an image signal, among a short-time exposed image signal obtained from pixels exposed to light for a short time and a long-time exposed image signal obtained from pixels exposed to light for a long time, that includes the flicker component due to the flickering of a light source. A composition processing unit changes a blend ratio when combining the short-time exposed image signal and the long-time exposed image signal according to the amplitude of the flicker component, and combines the short-time exposed image signal and the long-time exposed image signal in accordance with the blend ratio. Furthermore, an image-capture control unit performs a control for changing the exposure time of the image signal that includes the flicker component according to the period of the flicker component. The present technology can be applied to, e.g., an image-capturing device with which it is possible to capture a HDR image.
