Method and system for fine tuning frequency and phase of a sampling clock of analog signals (R, G, B) having digital information, for sampling the analog signals within an optimal sampling period, enabling optimal display by a digital display device (). Small amount of information from input signals is required for rapidly and accurately determining values of frequency and phase of the sampling clock. After measuring using a measurement system () and obtaining pixel values while sweeping phase values of signals using a phase locked loop (PLL) mechanism (), there is determining values of two parameters, (i) error of an initial frequency value of the sampling clock (Rx clock), proportional to error of an initial phase locked loop (PLL) division factor value, and (ii) phase of the sampling clock, without need for making additional measurements based on these values, using a control unit ().

Fine tuning a sampling clock of analog signals having digital information for optimal digital display

A method of electronic Keystone correction for electronic devices having visual displays which exhibit optical distortion on the display screen. The corrective method is based on computation and electronic (physical) manipulation of the pixels of a visual display screen grid, and features the principle steps of: 1) characterization of the size of an input image, 2) determination of the number of generated pixels in the output image, 3) determination of the real position of each pixel in the output image by performing an electronic distortion to the input image opposite to the optical distortion of the input image, 4) interpolation of the output value of all color components of each pixel of the input image, 5) correction of (non-uniform) edge effects at both ends of each line of pixels, 6) transmission of the output corrected image to the electronic display device, individually, pixel by pixel, or as complete set of corrected pixels of the image, and 7) display of the perfected corrected optical image. The method of this invention solves at least two universally known optical distortion problems involving trapezoidal distortion and computerized diagonal line drawing. Moreover, the method of this invention is applicable to real time domain of operation of electronic devices with visual displays.
