<P>PROBLEM TO BE SOLVED: To provide a solid-state imaging device which can realize a highly accurate illuminance detection and a camera module. <P>SOLUTION: According to one embodiment, a solid-state imaging device 12 includes an image sensor 20, a luminance average calculating unit 21, a threshold generation unit 22, a luminance integrating unit 23, a luminance observation value calculating unit 24, and an illuminance value conversion unit 25. The luminance average calculating unit 21 calculates the average of a luminance value for each pixel. The threshold generation unit 22 generates a threshold at a luminance level, based on an average value calculated in the luminance average calculating unit 21. The luminance observation value calculating unit 24 calculates a luminance observation value, based on an integration result in the luminance integrating unit 23. The luminance observation value is the observation result of the luminance for an entire imaging screen. The illuminance value conversion unit 25 converts the luminance observation value from the luminance observation value calculating unit 24 to an illumination value. The luminance integrating unit 23 integrates the luminance value discriminated by comparison with the threshold generated in the threshold generation unit 22, of the luminance values detected in the image sensor 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
