1. An image processing method, performed by an electronic device, the electronic device comprising multiple narrow-band filters and at least one wide-band filter,
the method comprising:
acquiring a target object through each of the narrow-band filters to obtain a narrow-band channel image comprising the target object, the narrow band filters comprising at least three filters with each narrow-band filter configured to output a respective channel of infrared color, and the at least one wide-band filter is configured to output a grey narrow-band channel image without a narrow band filtering effect;
fusing multiple narrow-band channel images in one-to-one correspondence with the multiple narrow-band filters to obtain a color image comprising a contour of the target object;
acquiring the target object through the at least one wide-band filter to obtain a grayscale wide-band channel image comprising the target object, the grayscale wide-band channel image having no wavelength differentiation; and
performing image enhancement processing on the color image comprising the contour of the target object based on the grayscale wide-band channel image to obtain the enhanced color image that also comprises the contour of the target object.
