Image sensing device including different types of sub-pixels and imaging device including the same

An imaging device comprising:

• an image sensing device comprising a plurality of pixels, each pixel configured to respond to incident light to produce photocharges corresponding to the incident light and include a first sub-pixel and a second sub-pixel surrounding the first sub-pixel, wherein the first sub-pixel is one of a color sub-pixel configured to selectively sense first color light within the incident light and a white sub-pixel configured to sense the incident light at different colors;
• and the second sub-pixel is the other of the color sub-pixel and the white sub-pixel;
• and
• an image signal processor communicatively coupled to the plurality of pixels and configured to process image data generated from each of the first sub-pixel and the second sub-pixel,
• wherein the image signal processor is configured to:
• determine data indicating a result of calculation between first image data generated from the first sub-pixel and second image data generated from the second sub-pixel to be image data of each pixel including the first sub-pixel and the second sub-pixel.

An imaging device comprising:

• a pixel array including pixels that are arranged in rows and columns,
• wherein each pixel includes:
• a first sub-pixel including a first photoelectric conversion element disposed in a substrate and configured to produce an electrical signal in response to first light incident to the first photoelectric conversion element;
• and
• a second sub-pixel including a second photoelectric conversion element disposed in the substrate and configured to produce a second electrical signal in response to second light incident to the second photoelectric conversion element,
• wherein one of the first sub-pixel and the second sub-pixel is a white sub-pixel configured to transmit incident light to a corresponding photoelectric conversion element without optically filtering the incident light, and
• wherein:
• the first sub-pixel is disposed at a center of each pixel;
• the second sub-pixel is arranged to surround the first sub-pixel;
• and
• the first sub-pixel is configured to have a larger area than an area of the second sub-pixel.
