Solid-state imaging device, image processing apparatus, and a camera module having an image synthesizer configured to synthesize color information

摘要

According to one embodiment, a solid-state imaging device includes a first image sensor, a second image sensor, and an image pickup processing circuit. The first image sensor is configured to output a first image signal according to an intensity distribution of each of color lights from an object. The second image sensor is configured to output a second image signal according to a luminance distribution of the light from the object. The image pickup processing circuit includes an image synthesizer. The image synthesizer is configured to synthesize color information included in the first image signal and luminance information included in the second image signal.

1. A solid-state imaging device comprising:
a first image sensor configured to output a first image signal according to an intensity distribution of each of color lights from an object; a second image sensor configured to output a second image signal according to a luminance distribution of the light from the object; and an image pickup processing circuit configured to process the first image signal and the second image signal, wherein the image pickup processing circuit includes an image signal separator configured to separate the first image signal which has been received from the first image sensor, into color information and first luminance information, a luminance information synthesizer configured to synthesize the first luminance information and second luminance information included in the second image signal with each other so as to produce synthesized luminance information, an image synthesizer configured to synthesize the color information output from the image signal separator and the synthesized luminance information produced by the luminance information synthesizer with each other so as to produce synthetic image data, a parallax amount calculator configured to calculate parallax amount of a first image acquired by the first image sensor and a second image acquired by the second image sensor, and a parallax corrector configured to correct a parallax between the first image and the second image, and the parallax amount calculator calculates the parallax amount by using the first luminance information output from the image signal separator and the second luminance information, and the luminance information synthesizer synthesizes the first luminance information and the second luminance information output from the parallax corrector with each other.
