Disclosed are an image semantic segmentation method, a logical integrated circuit, a system and an electronic device. The logical integrated circuit includes a convolution processing module and a deconvolution processing module. The convolution processing module performs convolution operation processing on an image to generate a piece of feature data of each and every feature image block of the image. The deconvolution processing module is configured to perform deconvolution operation processing on each piece of feature data to obtain an respective image block region; determine an approximation degree of the each piece of feature data and each and every preset semantic category of multiple preset semantic categories, and classify the each piece of feature data into a preset semantic category; and fill each image block region corresponding to the each piece of feature data with a filling color to achieve semantic segmentation of the image.
