Abstract: A method for independently adjusting six color classes with the consideration of boundary colors on a display device comprises steps of: detecting a plurality of pixels of a display device and calculate a first tint and a second tint of the pixels; defining a first pixel, the first tint and second tint of the first pixel both locating in the targeted color class; defining a second pixel, the second pixel being close to the first pixel, and the first tint and the second tint of the second pixel both locating in the neighboring of the targeted color class; defining a third pixel, said third pixel being neither the first pixel nor the second pixel; finding the first pixel and second pixel and adjusting their colors; and finding the third pixel and keeping its original color.

Abstract: Color adjustment includes dividing a color space into m tints, and then dividing each tint into n small areas. A chromaticity of a first color is adjusted by a first predetermined amount. An amount smaller than the first predetermined amount is generated according to the first predetermined amount. A chromaticity of a color close to the first color is adjusted by the amount smaller than the first predetermined amount. The adjusted amount of each small area decreases progressively. Similarly, a gain of a second color is adjusted by a second predetermined amount. An amount smaller than the second predetermined amount is generated according to the second predetermined amount. A gain of a color close to the second color is adjusted by the amount smaller than the second predetermined amount. Similarly, the adjusted amount of each small area decreases progressively.

Abstract: To strengthen a color of an image pixel without producing contour artifacts includes generating a relation between luminance and maximum chrominance vectors in each sub-color palette, generating a saturation factor of the image pixel according to a maximum chrominance vector corresponding to luminance of the image pixel, and adjusting a chrominance vector of the image pixel according to the saturation factor.

Abstract: A method for dynamic contrast enhancement by area gray-level detection with an image comprising steps of: transferring color space of said image from color space of RGB to that with brightness Y; making a brightness distribution histogram based on brightness of said image to get a corresponding relation between a gray level value and a count; dividing the whole brightness distribution into even brightness distribution areas by gray level value, and calculating each amount of counts of each brightness distribution area; according to said amount of counts, deciding a transfer curve to do brightness histogram equalization to the image for forming a new image with enhanced contrast.

Abstract: A robust layered 3:2 pulldown film mode source detection method is proposed. The method provides video signals of three fields, a current field, a last field and a next field. The video signals are used to determine a film source. The method comprises steps of: define a plurality of layers and each layer has a threshold and a counter; compare each difference between pixels of the last field and the next field with each layer's threshold to obtain a comparing result; according to said comparing result, determine a change of said counter of each layer; and determine a result sequence by said counter to decide said film mode source.

Abstract: A method is proposed for independently adjusting single color on a display device, which contains following steps: detecting multiple pixels of a display device, and separating out the 1st and the 2nd tint of these pixels; if the 1st and the 2nd tint of a pixel are with the same color class, then adjust the color of the pixel; and if the 1st and the 2nd tint of a pixel are with the different color classes, then maintain the color of the pixel in the original status.
