    摘要: A signal processing method comprises the steps of: inputting three signals specifying a color of one pixel; and generating four signals from the input three signals, wherein each of said four signals represents intensities of four different colors to display a color of one pixel by mixing colors, wherein said generating step includes a first converting step of converting the input three signals to two signals representing intensities of two colors among the four colors and a signal representing intensity of a mixed color obtained by mixing (a) the four colors or (b) a plurality of colors among the four colors; and a second converting step of converting the signal representing intensity of the mixed color to a plurality of signals representing intensities of a plurality of colors including at least other two colors different from the two colors.

    摘要: An image processing method includes the steps of detecting a dynamic range of input image data, performing resolution conversion processing to increase the number of grayscale levels of the input image data, and performing dithering processing to reduce the number of grayscale levels of each pixel of the input image data. The number of pseudo grayscale levels in the dithering processing is determined, based on a parameter indicating the level of the dynamic range and a parameter concerning the resolution conversion processing.

    摘要: An image processing method includes the steps of performing resolution conversion processing on input image data to increase the number of grayscale levels, performing edge enhancement processing to increase the number of grayscale levels of the input image data, and performing dithering processing to reduce the number of grayscale levels of each pixel of the input image data. The number of pseudo grayscale levels is determined, based on a combination of a parameter concerning the resolution conversion processing and a parameter indicating the level of the edge enhancement processing.
