  • Imaging element and imaging device
    Patent number: 12615447
    Abstract: A variation in sensitivity of pixels is reduced. A pixel array unit includes a Bayer array, a red pixel group with red pixel blocks in two rows and two columns, a green pixel group with green pixel blocks in two rows and two columns, and a blue pixel group with blue pixel blocks in two rows and two columns. Each pixel group includes pixel blocks arranged in two rows and two columns with the pixels including a color filter transmitting light of the color of the respective pixel group, and with an on-chip lens common to the pixel group. Each pixel group performs photoelectric conversion of incident light transmitted through the respective color filters and generates an image signal corresponding to the respective pixel group color. The on-chip lens has a different shape for each of the red pixel group, the green pixel group, and the blue pixel group.
