SOLID-STATE IMAGING DEVICE, CAMERA MODULE, AND ILLUMINANCE DETECTION METHOD

According to one embodiment, a solid-state imaging device includes a luminance integrating unit, a luminance observation value calculating unit, and an illuminance value conversion unit. The luminance integrating unit integrates a luminance value detected for every pixel. The luminance observation value calculating unit calculates a luminance observation value based on an integration result in the luminance integrating unit. The luminance observation value is an observation result of the luminance for an entire imaging screen. The illuminance value conversion unit converts the luminance observation value to an illuminance value. The luminance integrating unit integrates the luminance value discriminated in accordance with a condition set with respect to a luminance level.
