Method for black level correction, non-transitory computer-readable storage medium, and chip

A non-transitory computer-readable storage medium, storing with a computer instruction, wherein the computer instruction is configured to enable a computer to execute a method for black level correction, comprising:

• determining whether a first image sensor and/or a second image sensor triggers a calibration mode based on a calibration signal;
• performing, in response to the first image sensor triggering the calibration mode and the second image sensor not triggering the calibration mode, first image acquisition through the first image sensor based on a first automatic exposure configuration, and obtaining a calibration result by performing black level calibration;
• obtaining, in response to the first image sensor not triggering the calibration mode and the second image sensor triggering the calibration mode, an image to be processed by performing second image acquisition through the first image sensor based on a second automatic exposure configuration;
• and
• performing black level correction on the image to be processed based on the second automatic exposure configuration and the calibration result;
• wherein the method further comprises:
• setting a calibration frequency for the first image sensor and/or the second image sensor, wherein the calibration frequency at least comprises a calibration acquisition frequency and a calibration acquisition frame number, and the calibration acquisition frame number is greater than or equal to 1;
• and
• obtaining the calibration signal based on the calibration frequency, wherein the calibration signal is used to instruct the first image sensor and/or the second image sensor to start the calibration mode.
