Abstract
A circuit for adjusting image is adapted for rear projection display. The circuit for adjusting image includes a parameter input unit, a data buffer unit, and a geometry transfer unit. The parameter input unit is used to provide a vertical and a horizontal axis amendment parameters. The data buffer unit couples the parameter input unit to buffer the vertical axis amendment parameter and the horizontal axis amendment parameter. The geometry transfer unit is used to receive input frame data with a plurality of pixels, and then every pixel's vertical axis coordinates multiply the vertical axis amendment parameter to transfer every pixel to a new vertical axis coordinate, and every pixel's horizontal axis coordinates multiply the horizontal axis amendment parameter to transfer every pixel to a new horizontal axis coordinate. Finally, the transferred new vertical and horizontal axis coordinates are transmitted to a display for displaying images for users to watch.
