Abstract
A display panel driver includes: a correction calculation section which performs correction calculations on input image data to generate saturation-enhanced output image data and a drive circuitry driving the display panel in response to the output image data and a starting point control section. The correction calculation section generates red (R) data, green (G) data and blue (B) data of the output image data by performing the correction calculations on R data, G data and B data of the input image data, respectively. The starting point control section controls the positions of starting points of the input-output curves of the correction calculations.
Claims20
A display driver, comprising:
- processing circuitry configured to:
- control a starting point of an input-output curve between input color data and output color data for performing correction calculations, the starting point of the input-output curve corresponding to an allowed minimum value of the input color data;
- and
- enhance a saturation of received image data by performing a correction calculation for at least one color of a plurality of colors of the image data;
- and
- drive circuitry configured to drive a display panel in response to the enhanced-saturation image data.
An image processing apparatus, comprising:
- starting point control circuitry configured to control a starting point of an input-output curve between input color data and output color data for performing correction calculations, the starting point of the input-output curve corresponding to an allowed minimum value of the input color data;
- and
- correction circuitry configured to enhance a saturation of received image data by performing a correction calculation for at least one color of a plurality of colors of the image data.
A method, comprising:
- controlling a starting point of an input-output curve between input color data and output color data for performing correction calculations, the starting point of the input-output curve corresponding to an allowed minimum value of the input color data;
- and
- generating, using the starting point, saturation-enhanced image data by performing a correction calculation for at least one color of a plurality of colors of received image data.
