Abstract: An electronic device includes an image sensor including an image generator configured to generate and output a pixel image, an image processing device configured to process the pixel image, and a storage unit configured to store the pixel image, and an application processor configured to generate a mode setting signal and configured to transmit the generated mode setting signal to the image processing device. The image processing device is configured to generate a plurality of path selection signals for selecting a path to use by the image processing device to process the pixel image, based on the mode setting signal. The image processing device selects a compression ratio for the pixel image based on at least one of an input signal of a user, an analysis result of the pixel image, and a motion signal of the image sensor, and compresses the pixel image based on the selected compression ratio.

Abstract: The present disclosure provides an image encoder. The image encoder is configured to encode an original image and reduce compression loss. The image encoder comprises an image signal processor and a compressor. The image signal processor is configured to receive a first frame image and a second frame image and generates a compressed image of the second frame image using a boundary pixel image of the first frame image. The image signal processor may include memory configured to store first reference pixel data which is the first frame image. The compressor is configured to receive the first reference pixel data from the memory and generate a bitstream obtained by encoding the second frame image based on a difference value between the first reference pixel data and the second frame image. The image signal processor generates a compressed image of the second frame image using the bitstream generated by the compressor.
