1. An image obtaining method, applied to an image sensor, the image sensor comprising a filter array and a pixel array, the filter array comprising minimal repeating units, each minimal repeating unit comprising a plurality of filter groups, each filter group comprising a color filter and a panchromatic filter, a waveband of light passing through the color filter being narrower than a waveband of light passing through the panchromatic filter, the color filter and the panchromatic filter each comprising a plurality of sub-filters, the pixel array comprising a plurality of pixels, each pixel corresponding to one sub-filter in the filter array and being configured to receive light passing through the sub-filter to generate an electrical signal, the method comprising:
outputting an image in at least one of a plurality of image output modes, wherein the plurality of image output modes comprising:
a full-size mode in which a first image is obtained according a first pixel value read from each pixel;
a first binning mode in which a second image is obtained according to a second pixel value and a third pixel value, wherein the second pixel value is read from binning of a plurality of pixels corresponding to the panchromatic filter, and the third pixel value is read from binning of a plurality of pixels corresponding to the color filter; and
a second binning mode in which a third image is obtained according to a fourth pixel value and a fifth pixel value, wherein the fourth pixel value is read from binning of a plurality of pixels corresponding to all panchromatic filters in the filter group, and the fifth pixel value is read from binning of a plurality of pixels corresponding to all color filters in the filter group.
