| Abstract: | The scaler chip is used in LCD system, and translates the input images which have different resolution to the fixed resolution image. This article started with the general video signal and working condition of scaler, then analyze and define the parameters needed to be measured, these parameters included the polar of input control signals, some signal period and the dimensions of active pixel region. Furthermore, principle and means based on demarcating the timings of the input signals with counter were depicted to implement measurement. Register save result of counter to compute, finally the measurement result are presented. The design can measure rapidly and avail the input signal format, and is satisfied to the scale system performance requirement. |
