Abstract
Disclosed in the present application are an image acquisition method, an imaging apparatus, an electronic device, and a non-transitory computer-readable storage medium. The image acquisition method includes: controlling exposure of a pixel array; and performing an interpolation process on a first colored original image and a second colored original image according to a first panchromatic original image, and fusing an interpolated image and the first panchromatic original image to obtain a target image with same resolution as resolution of the pixel array.

An image acquisition method applied to an image sensor, wherein the image sensor comprises a pixel array, the pixel array comprises a plurality of panchromatic photosensitive pixels and a plurality of color photosensitive pixels, and the color photosensitive pixels have a narrower spectral response than the panchromatic photosensitive pixels;
- the pixel array comprises minimal repeating units, each of the minimal repeating units comprises a plurality of subunits, and each of the subunits comprises a plurality of monochromatic photosensitive pixels and a plurality of panchromatic photosensitive pixels;
- the image acquisition method comprises:
- controlling exposure of the pixel array, wherein for a plurality of photosensitive pixels in a same subunit, at least one of the monochromatic photosensitive pixels is exposed for a first exposure time, and at least another one of the monochromatic photosensitive pixels is exposed for a second exposure time shorter than the first exposure time, and at least one of the panchromatic photosensitive pixels is exposed for a third exposure time shorter than the first exposure time;
- and
- performing an interpolation process on a first colored original image and a second colored original image according to a first panchromatic original image, and fusing an interpolated image and the first panchromatic original image to obtain a target image with a same resolution as resolution of the pixel array;
- wherein the first colored original image is obtained from first-color information generated by the monochromatic photosensitive pixels exposed for the first exposure time, and the second colored original image is obtained from second-color information generated by the monochromatic photosensitive pixels exposed for the second exposure time;
- and the first panchromatic original image is obtained from first panchromatic information generated by the panchromatic photosensitive pixels exposed for the third exposure time.
