DISPLAY DEVICE, DISPLAY DATA PROCESSING DEVICE, AND DISPLAY DATA PROCESSING METHOD

摘要

A display device includes: an extraction unit extracting an edge component of a display data signal; an adder unit adding an edge component to the display data signal; a signal generation unit generating a control signal in accordance with the display data signal and an output signal of the adder unit; a correction unit carrying out correction processing on the edge component in accordance with the control signal and outputting the corrected edge component to the adder unit; and a display unit carrying out a display operation in accordance with the output signal of the adder unit.

主权项

1. A display controller comprising:
a circuitry configured to output a second image data, the second image data being generated by adding an edge component to an first image data; and wherein the edge component includes a minus direction component and a plus direction component, and the circuitry is configured to execute at least one of image processings selected from a group consisting of: (i) a first processing so as to set a magnitude of the minus direction component greater when a gradation level of the display data is high than a magnitude of the minus direction component when a gradation level of the display data is low; and (ii) a second processing so as to set a magnitude of the plus direction component smaller when a gradation level of the display data is high than a magnitude of the plus direction component when a gradation level of the display data is low.
