1. An electronic device comprising:
an image sensor configured to sense light sourced from a subject and generate an image layer; and
an image processor configured to:
generate a feature map by performing a convolution operation on the image layer and a fixed-size kernel;
generate a final feature map by performing convolution operations on a variable-size kernel and the feature map; and
generate image data including channels in which the final feature map is classified for each color,
wherein the image processor comprises:
a fix network configured to generate the feature map by performing the convolution operation on the fixed-size kernel and the image layer;
a variable network configured to generate a plurality of feature maps by performing the convolution operations using the variable-size kernel, wherein the plurality of feature maps include the final feature map and are different from the feature map;
an image detector configured to detect the channels classified for each color from the final feature map among the plurality of feature maps and generate feature data including the channels; and
a data output circuit configured to output the feature data as it is, or output the image data by processing, compressing, or encrypting the feature data.
