Abstract
An electronic device may include noise statistics circuitry to receive input image data corresponding to an image displayable on an electronic display. The input image data may include one or more channels of pixel data. The noise statistics circuitry may also determine a subset of pixel data of a channel of pixel data that qualifies for statistics gathering according to qualification criteria. Additionally, the noise statistics circuitry may determine noise statistics based on the subset of pixel data, and identify image features within the subset of pixel data based on the noise statistics. The image features may include frequency signatures, differentiated from noise, that correspond to features of content of the image. The electronic device may also include enhancement circuitry to enhance the input image data based on the noise statistics and the identified image features. Such enhancement circuitry may substantially preserve the image features within the input image data.
