Control method and electronic device

An electronic device, comprising:

• a pixel-cell array, comprising a plurality of photosensitive pixel-units, each photosensitive pixel-unit of the photosensitive pixel-units comprising at least two exposure pixels, the at least two exposure pixels comprising at least one medium-exposure pixel;
• a processor;
• and
• a memory, storing a computer program operable on the processor, wherein the computer program, when executed by the processor, implements:
• determining an ambient brightness level of a photographing environment;
• adjusting a first ratio to be a first value, in response to a brightness level of the photographing environment belonging to a high-level or a low-level, wherein the first ratio indicates a ratio of the at least one medium-exposure pixel in the each photosensitive pixel-unit;
• and
• adjusting the first ratio to be a second value, in response to the brightness level of the photographing environment belonging to a medium-level, wherein the low-level, the medium-level, and the high-level are in an ascending order, and the first value is greater than the second value;
• wherein at least one of the at least one medium-exposure pixel in the each photosensitive pixel-unit is switched to at least one of a short-exposure pixel and a long-exposure pixel, such that the first ratio is reduced to be the second value;
• wherein an exposure duration of a long-exposure pixel is greater than an exposure duration of a medium-exposure pixel, and the exposure duration of the medium-exposure pixel is greater than an exposure duration of a short-exposure pixel.

A non-transitory computer-readable storage medium, storing a computer program, when executed by a processor, implements:

• determining an ambient brightness level of a photographing environment;
• adjusting a first ratio to be a first value, in response to a brightness level of the photographing environment belonging to a high-level or a low-level, wherein the first ratio indicates a ratio of the at least one medium-exposure pixel in the each photosensitive pixel-unit;
• and
• adjusting the first ratio to be a second value, in response to the brightness level of the photographing environment belonging to a medium-level, wherein the low-level, the medium-level, and the high-level are in an ascending order, and the first value is greater than the second value;
• wherein the adjusting a first ratio to be the first value comprises:
• switching at least one of a short-exposure pixel and a long-exposure pixel in the each photosensitive pixel-unit to at least one of another medium-exposure pixel, such that the first ratio is increased to be the first value;
• wherein an exposure duration of a long-exposure pixel is greater than an exposure duration of a medium-exposure pixel, and the exposure duration of the medium-exposure pixel is greater than an exposure duration of a short-exposure pixel.
