Imaging method for image sensor, imaging apparatus, and electronic device

An imaging apparatus, comprising:

• an image sensor, comprising:
• a photosensitive pixel array;
• a filter arranged on the photosensitive pixel array, wherein the filter comprises an array of filter units, each filter unit and a plurality of adjacent photosensitive pixels covered by the filter unit in the photosensitive pixel array form a synthesized pixel;
• and
• an image processing module, connected to the image sensor, configured to read an output of the photosensitive pixel array, and to extract pixel values of photosensitive pixels within different synthesized pixels from a read-out single-frame high-resolution image, and to combine the pixel values so as to obtain a plurality of multiple-frame low-resolution images and to synthesize the plurality of multiple-frame low-resolution images.

A mobile terminal, comprising:

• a housing;
• a processor;
• a memory;
• a circuit board;
• a power supply circuit and an image sensor, wherein the circuit board is located in a space defined by the housing, the processor, the memory and the image sensor are disposed on the circuit board;
• the power supply circuit is configured to supply power for each circuit or component in the mobile terminal;
• the image sensor comprises a photosensitive pixel array and a filter arranged on the photosensitive pixel array, the filter comprises an array of filter units, each filter unit and a plurality of adjacent photosensitive pixels covered by the filter unit in the photosensitive pixel array form a synthesized pixel;
• the memory is configured to store executable program codes;
• the processor is configured to execute a program corresponding to the executable program codes by reading the executable program codes stored in the memory so as to perform acts of:
• reading an output of the photosensitive pixel array, extracting pixel values of photosensitive pixels within different synthesized pixels from a read-out single-frame high-resolution image, and combining the pixel values so as to obtain a plurality of multiple-frame low-resolution images;
• and
• synthesizing the plurality of multiple-frame low-resolution images.
