Patent ID: 7336288

Claim:
A sampling rate converting system for executing a conversion of a sampling rate of an image signal input into such a display that respective pixels each consisting of a plurality of subpixels are arranged in a matrix fashion and also respective pixels emit a light in response to a signal data corresponding to respective pixels to reproduce a luminance or a color every pixel, the system comprising: a subpixel number-of-pixel converter that inputs a high-definition luminance signal of a high-definition image signal whose number of pixels is larger than a number of pixels of the display, and outputs a subpixel sampling rate signal by converting a sampling rate of the high-definition luminance signal into a subpixel sampling rate based on a sampling rate in a direction along which the subpixels on the display are aligned and a number of subpixels constituting the pixel; a number-of-pixels-in-pixel-units converter that inputs the high-definition luminance signal, and applies a number-of-pixels converting process to the input high-definition image signal in units of pixel to output an interference suppressing signal; an image feature detector that senses a particular waveform pattern of a luminance signal or color difference signals constituting the high-definition image signal to output a control signal; and a mixer that mixes the subpixel sampling rate signal and the interference suppressing signal and controls a mixing rate thereof according to the control signal.
