Samsung patents image processor that adjusts settings based on data statistics

1. An image processing device comprising: an encoder configured to compress image data including pixel values of a pixel group in units of pixel groups to generate a bitstream and to decompress the bitstream to generate first restored data; and a decoder configured to receive the bitstream from the encoder and decompress the bitstream to generate second restored data, wherein the encoder comprises a first statistic circuit configured to generate first statistical data based on the first restored data and change a setting value of the encoder based on the first statistical data, wherein the decoder comprises a second statistic circuit configured to generate second statistical data based on the second restored data and change a setting value of the decoder based on the second statistical data, wherein the image sensor further comprises firmware configured to generate a first configuration parameter that corresponds to the setting value of the encoder by performing an arithmetic operation based on the first statistical data, wherein the encoder further comprises: a first advanced peripheral bus (APB) interface configured to receive the first configuration parameter from the firmware and transmit the first configuration parameter to at least one encoder register of the encoder, a first parameter generation circuit configured to receive the first statistical data from the first statistic circuit and generate a second configuration parameter that corresponds to the setting value of the encoder by performing the arithmetic operation based on the first statistical data; and a first multiplexer configured to receive the first configuration parameter from the first APB interface and receive the second configuration parameter from the first parameter generation circuit, select one of the first configuration parameter and the second configuration parameter, and transmit one of the first configuration parameter and the second configuration parameter that is selected to the at least one encoder register, such that the at least one encoder register changes the setting value of the encoder to the one of the first configuration parameter and the second configuration parameter that is selected.
