Abstract
Provided are an image sensor (10), a camera assembly (40), and a mobile terminal (90). The image sensor (10) includes panchromatic pixels and color pixels. The color pixels have a narrower spectral response than the panchromatic pixels, and the color pixels have a larger conversion gain than the panchromatic pixels.
Claims20
An image sensor, comprising:
- panchromatic pixels;
- and
- color pixels each having a narrower spectral response and a greater conversion gain than the panchromatic pixels, the conversion gain of each of the panchromatic pixels and the color pixels being in negative correlation with a capacitance value of an additional capacitor of the pixel;
- wherein each of the panchromatic pixels comprises a first additional capacitor connected to a floating diffusion unit of the panchromatic pixel, and each of the color pixels comprises no additional capacitor;
- or,
- wherein each of the panchromatic pixels comprises a first additional capacitor connected to a floating diffusion unit of the panchromatic pixel, each of the color pixels comprises a second additional capacitor connected to a floating diffusion unit of the color pixel, the capacitance value of the first additional capacitor of each of the panchromatic pixels is larger than the capacitance value of the second additional capacitor of each of the color pixels.
