Title:
IMAGE SENSOR, CAMERA ASSEMBLY, AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2021/159944
Kind Code:
A1
Abstract:
An image sensor (10), a camera assembly (40), and a mobile terminal (60). The image sensor (10) comprises panchromatic pixels and color pixels. The pixel area of the color pixels is greater than that of the panchromatic pixels. The doping concentration (C1) of the n-potential well layers (1172) of the panchromatic pixels is greater than the doping concentration (C2) of the n-potential well layers (1172) of the color pixels, so that the panchromatic pixels have a full well capacity greater than that of the color pixels; and/or, the depth (H1) of the n-potential well layers (1172) of the panchromatic pixels is greater than the depth (H2) of the n-potential well layers (1172) of the color pixels, so that the panchromatic pixels have the full well capacity greater than that of the color pixels.
