Abstract
An image sensor, a camera module, and an electronic device are provided. The image sensor includes a pixel array and a control circuit. The pixel array includes a plurality of row pixels and a plurality of column pixels. The control circuit is configured to receive a first instruction to control an intersection region of a part of the plurality of row pixels and a part of the plurality of column pixels to detect an illumination intensity. The control circuit is further configured to receive a second instruction to control at least part of the pixel array to acquire an image.
Claims19
An image sensor, comprising:
- a pixel array comprising a plurality of pixel rows and a plurality of pixel columns;
- and
- a control circuit configured to:
- receive a first instruction to control an intersection region of a part of the plurality of pixel rows and a part of the plurality of pixel columns to detect a illumination intensity;
- and
- receive a second instruction to control at least part of the pixel array to acquire an image,
- wherein the intersection region is a ring-shaped intersection region, and the ring-shaped intersection region is arranged to surround a center of the pixel array,
- wherein the ring-shaped intersection region is centrosymmetrically arranged with respect to the center of the pixel array, and
- wherein a ratio of an area of the intersection region to an area of the pixel array ranges from 0.1 to 0.2 or from 0.3 to 0.4.
A camera module, comprising:
- an image sensor;
- and
- an optical filter arranged above the image sensor,
- wherein the image sensor comprises:
- a pixel array comprising a plurality of pixel rows and a plurality of pixel columns;
- and
- a control circuit configured to:
- receive a first instruction to control an intersection region of a part of the pixel rows and a part of the pixel columns to detect a illumination intensity, so as to control the image sensor to operate in a light sensing mode;
- and
- receive a second instruction to control the pixel array to acquire an image, so as to control the image sensor to operate in an imaging mode,
- wherein the intersection region is a ring-shaped intersection region and the ring-shaped intersection region is arranged to surround a center of the pixel array,
- wherein the ring-shaped intersection region is centrosymmetrically arranged with respect to the center of the pixel array, and

An electronic device, comprising:
- a camera module comprising:
- an image sensor comprising:
- a pixel array comprising a plurality of pixel rows and a plurality of pixel columns;
- and
- a control circuit configured to:
- receive a first instruction to control an intersection region of a part of the plurality of pixel rows and a part of the plurality of pixel columns to detect a illumination intensity;
- and
- receive a second instruction to control at least part of the pixel array to acquire an image;
- and
- an optical filter arranged above the image sensor;
- and
- a processor coupled to the image sensor and configured to generate the first instruction and the second instruction,
- wherein the intersection region is a ring-shaped intersection region and the ring-shaped intersection region is arranged to surround a center of the pixel array,
- wherein the ring-shaped intersection region is centrosymmetrically arranged with respect to the center of the pixel array, and
- wherein a ratio of an area of the intersection region to an area of the pixel array ranges from 0.1 to 0.2 or from 0.3 to 0.4.
