1. An electronic device with image identification function, comprising: a storage unit configured to store a color source image in memory; texture determination circuitry, electrically connected to the storage unit, configured to perform texture feature extraction on the color source image to obtain a plurality of texture parameters; color determination circuitry, electrically connected to the storage unit, configured to perform texture feature extraction on the color source image to obtain a plurality of color momentums; and identification circuitry, electrically connected to the texture determination circuitry and the color determination circuitry, configured to weight the plurality of texture parameters and the plurality of color momentums to obtain an image identification parameter corresponding to the color source image and to output the image identification parameter to the storage unit, wherein weights corresponding to the plurality of texture parameters and weights corresponding to the plurality of color momentums are adjusted according to size of the color source image.
