Image sensor, control method, camera component and mobile terminal with raised event adaptability and phase detection auto focus

A control method, used in an image sensor, the image sensor comprising a two-dimensional pixel array and a lens array, the two-dimensional pixel array comprising a plurality of pixels, wherein at least a part of the pixels comprise two sub-pixels, a rectangular coordinate is established by taking the pixel as an origin, a length direction of the two-dimensional pixel array as an x-axis, and a width direction of the two-dimensional pixel array as a y-axis, the two sub-pixels lie in both a positive half axis and a negative half axis of the x-axis and lie in both a positive half axis and a negative half axis of the y-axis;

• wherein the lens array comprises a plurality of lenses, each covering one of the pixels;
• the control method comprising:
• exposing the sub-pixels to output sub-pixel information;
• calculating a phase difference according to the sub-pixel information to perform a focus process;
• and
• in an in-focus condition, exposing the plurality of pixels in the two-dimensional pixel array to obtain a target image,
• wherein the two-dimensional pixel array comprises a smallest repeating unit, and the smallest repeating unit comprise a plurality of panchromatic pixels and a plurality of color pixels.
