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 condition judging unit judges whether a target pixel corresponds to a defect condition based on a signal of the target pixel and a signal of a horizontal peripheral pixel. A signal substituting unit performs signal substitution on the target pixel corresponding to the defect condition. When the condition judging unit judges that at least one of a vertical peripheral pixel and an oblique peripheral pixel corresponds to the defect condition, the signal substituting unit stops the signal substitution on the target pixel.

Image processing device with defect correcting circuit and image processing method

A shading correcting device includes a correction-coefficient interpolation unit that calculates a color shading correction coefficient used at a position of a pixel at which the color shading correction coefficient is not set among pixels in an image signal by an interpolation process using a color shading correction coefficient set at a predetermined position. A color shading correction coefficient sent to the correction-coefficient interpolation unit is a color shading correction coefficient that is for a first color and corresponds to a pixel value of a second color adjacent to a pixel of the first color.

Shading correcting device and imaging apparatus

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.
