Abstract: An image processing method based on a dither algorithm and a display device are disclosed. The method includes: obtaining a to-be-displayed image, and determining a first region and a second region of the to-be-displayed image, where the first region and the second region are determined according to a coverage range of a visual field of a user on a display screen; determining a first dither algorithm corresponding to the first region and a second dither algorithm corresponding to the second region, where parameter matrices the first dither algorithm and the second dither algorithm are different; and obtaining a rendered image of the to-be-displayed image by rendering the first region according to the first dither algorithm and rendering the second region according to the second dither algorithm, and displaying the rendered image on the display screen.

Abstract: The present disclosure provides a data mutex filter circuit and a data mutex filtering method. The data mutex filter circuit has a main input terminal and a main output terminal and including a preprocessing sub-circuit and a 1st-stage filter sub-circuit to an Nth-stage filter sub-circuit which are cascaded, N being an integer greater than or equal to 2. The 1st-stage filter sub-circuit has an input terminal coupled to the preprocessing sub-circuit, and the Nth-stage filter sub-circuit has an output terminal coupled to the main output terminal. Each stage of filter sub-circuit is configured to compare whether input data currently received at the main input terminal is the same as history data stored therein, and feed back a comparison result to the preprocessing sub-circuit; the preprocessing sub-circuit outputs corresponding data to the 1st-stage filter sub-circuit according to the comparison result fed back by each stage of filter sub-circuit.
