The driver circuit includes a first controlling circuit that outputs, to a gate of the auxiliary pMOS transistor, a first controlling signal that rises in synchronization with a rising of the first pulse signal and falls after a delay from a falling of the first pulse signal. The driver circuit includes a second controlling circuit that outputs, to a gate of the auxiliary nMOS transistor, a second controlling signal that rises in synchronization with a rising of the second pulse signal and falls after a delay from a falling of the second pulse signal.

A pixel-interpolation processing unit generates a sensitivity level value of an insufficient color component according to interpolation processing of image signals. A sensitivity level value of an insufficient color component in a pixel of attention is calculated, according to an arithmetic operation corresponding to an acquired color component of the pixel of attention, by assuming a geometric figure including sensitivity level values of acquired color components as vertexes. As the geometric figure, the same figure is used irrespectively of which color component the acquired color component is.

According to one embodiment, an image processing device includes a defect correcting unit, a noise-reduction processing unit, and a selecting unit. The defect correcting unit executes defect correction on a target pixel. The defect correcting unit switches, according to the level of contrast determined concerning a plurality of peripheral pixels, a first correction value obtained through averaging processing for signal values of the peripheral pixels and a second correction value other than the first correction value.
