Abstract:
According to one embodiment, an image processing device includes a black level regulating unit. The black level regulating unit has a frame integration average holding unit. A frame integration average is an integration average of an optical black signal using a video frame as a unit. The frame integration average holding unit holds the frame integration average as a signal to be applied to a black level regulation of an effective pixel signal. The frame integration average holding unit updates the frame integration average when an image pickup condition is changed.
