Method and apparatus for obtaining high resolution image, and electronic device for same

An image processing apparatus, applied in an electronic device, wherein the electronic device comprises an imaging apparatus comprising an image sensor, the image sensor comprises an array of photosensitive pixel units and an array of filter units arranged on the array of photosensitive pixel units, each filter unit corresponds to one photosensitive pixel unit, and each photosensitive pixel unit comprises a plurality of photosensitive pixels;

• the image processing apparatus comprises a non-transitory computer-readable medium comprising computer-executable instructions stored thereon, and an instruction execution system which is configured by the instructions to implement:
• outputting a merged image by the image sensor, wherein, the merged image comprises an array of merged pixels, the photosensitive pixels in a same photosensitive pixel unit are collectively output as one merged pixel;
• determining whether there is a target object in the merged image;
• and
• converting the merged image into a restoration image using a second interpolation algorithm, wherein the restoration image comprises restoration pixels arranged in an array, each photosensitive pixel corresponds to one restoration pixel;
• and converting the restoration image into a merged true-color image when there is a target object in the merged image.

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

• the circuit board is enclosed by the housing;
• the processor and the memory are positioned on the circuit board;
• the power supply circuit is configured to provide power for respective circuits or components of the electronic device;
• the imaging apparatus comprises an image sensor, wherein the image sensor comprises an array of photosensitive pixel units and an array of filter units arranged on the array of photosensitive pixel units, each filter unit corresponds to one photosensitive pixel unit, and each photosensitive pixel unit comprises a plurality of photosensitive pixels;
• the memory is configured to store executable program codes;
• and
• the processor is configured to run a program corresponding to the executable program codes by reading the executable program codes stored in the memory, to perform following operations:
• outputting a merged image by the image sensor, wherein, the merged image comprises an array of merged pixels, and the photosensitive pixels in a same photosensitive pixel unit are collectively output as one merged pixel;
• determining whether there is a target object in the merged image;
• and
• when there is the target object in the merged image, converting the merged image into a restoration image using a second interpolation algorithm, wherein the restoration image comprises restoration pixels arranged in an array, each photosensitive pixel corresponds to one restoration pixel;
• and converting the restoration image into a merged true-color image.
