According to one embodiment, a solid-state imaging device includes an illuminance value calculating unit and an illuminance value output unit. The illuminance value calculating unit calculates an illuminance value based on an integration result of luminance values. The illuminance value output unit outputs the illuminance value calculated by the illuminance value calculating unit by setting, as a target, a subject image obtained through application of one of two or more illuminance measurement conditions. The two or more illuminance measurement conditions are set in advance by varying at least one of an electronic shutter time and an analog gain.

According to one embodiment, a camera module has an exposure control unit. When an exposure error has reached within a coring range by first exposure control, the exposure control unit switches exposure control from the first exposure control to second exposure control. The exposure error shows a deviation of an exposure evaluation value to an exposure target value. In the second exposure control, an exposure change amount is reduced than at the time of the first exposure control. When the exposure error has reached a zero level by the second exposure control, the exposure control unit stops the exposure control.

According to one embodiment, a solid-state imaging device includes a signal level comparing circuit. The signal level comparing circuit compares the levels among the signals of first peripheral pixels, the levels among the signals of second peripheral pixels, the levels among the signals of third peripheral pixels. The first peripheral pixels are arranged with the pixels for colors other than the color for the target pixel interposed between the first peripheral pixels and the target pixel. The second peripheral pixels are disposed on extension lines in directions from the target pixel to the first peripheral pixels, and the third peripheral pixels are disposed between the second peripheral pixels.

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.

An analog signal photo-electrically converted in a pixel of a light receiving area is converted to a digital signal by an ADC. The digital signal is processed by a digital signal processing circuit, and then, successively output as a digital video signal. The digital signal processing circuit has a first signal processing block for detecting and correcting a pixel defect and preventing a noise, and a second signal processing block for restoring apparent resolution lost by the processing by the first signal processing block.
