Imaging Control Method and Apparatus, Electronic Device, and Computer Readable Storage Medium

An apparatus for imaging control, applicable to an imaging device, and the apparatus comprising:

• a processor;
• and
• a memory, configured to store software modules executable by the processor,
• wherein the processor is configured to run a program corresponding to the software modules by reading the software modules stored in the memory, the software modules comprising:
• a first determining module, configured to determine whether a shooting scene of the imaging device is a dim environment;
• a second determining module, configured to determine an exposure ratio of a long exposure pixel to a short exposure pixel of the imaging device when the shooting scene is the dim environment;
• a third determining module, configured to determine that the shooting scene is with a high dynamic range when the exposure ratio is greater than a first exposure ratio threshold;
• a control module, configured to, when the shooting scene is with the high dynamic range, control a pixel unit array of the imaging device to expose for a plurality of times with at least two exposure durations to generate a plurality of first images;
• and
• a processing module, configured to perform compositing process according to the plurality of first images to generate a composited image.

An electronic device, comprising a housing, a memory, a processor, a circuit board, a power supply circuit, and an imaging device, wherein,

• the circuit board is arranged inside a space enclosed by the housing;
• the processor and the memory are disposed on the circuit board;
• the power supply circuit is configured to provide power for respective circuits or components of the electronic device;
• the imaging device comprises a pixel unit array composed of a plurality of photosensitive pixel units, each photosensitive pixel unit comprises a plurality of original pixels, and the plurality of original pixels in each photosensitive pixel unit comprise long exposure pixels, short exposure pixels and medium exposure pixels;
• the memory is configured to store executable program codes;
• and
• the processor is configured to execute a program corresponding to the executable program codes by reading the executable program codes stored in the memory to:
• determine whether a shooting scene of the imaging device is a dim environment;
• determine an exposure ratio of the long exposure pixel to the short exposure pixel when the shooting scene is the dim environment;
• determine that the shooting scene is with a high dynamic range, when the exposure ratio is greater than a first exposure ratio threshold;
• control the pixel unit array to expose for a plurality of times with at least two exposure durations, to generate a plurality of first images;
• and
• compost the plurality of first images to generate a composited image.
