Abstract:
1. A display control circuit for converting input digital video data, which is input with a first cycle and has a first number of pixels, into output digital video data having a second number of pixels and a second cycle so as to be displayed, said circuit comprising: a selector for selecting one among a plurality of preset coefficients no greater than 1; a first multiplier circuit for multiplying input video data by the selected coefficient; a second multiplier circuit for multiplying input video data of one pixel adjacent to the input digital video data of the one pixel by (1−the coefficient); and an adder circuit for adding an output of the first multiplier circuit with an output of the second multiplier circuit, wherein the adder circuit outputs output digital video data; the output digital video signal is a signal supplied to a display apparatus employing a delta arrangement in which pixels of the same color are offset-arranged in each line, and the pixel number adjusting circuit modifies the weight for the odd-number lines and the even-number lines.
