1. A method of operation of a de-interlacer/scaler for display of stereoscopic images, comprising: determining whether or not stereoscopic images are to be displayed; if not, then: enabling image processing algorithms at a de-interlacer/scaler that utilize pixel data for temporally or spatially adjacent pixels that represent images, and at the de-interlacer/scaler, receiving consecutive frames of video information representing the images; and sending non-stereoscopic images from the de-interlacer/scaler to a display; if so, then: at the de-interlacer/scaler, receiving consecutive frames of video information that contain alternating left and right eye images from a decoder, and at the de-interlacer/scaler, disabling all image processing algorithms that utilize pixel data for temporally or spatially adjacent pixels that represent images, where at least one pixel is for the left eye and one pixel is for the right eye; at the de-interlacer/scaler, carrying out at least one image processing algorithm that does not utilize pixel data for temporally or spatially adjacent pixels that represent images; and sending stereoscopic images from the de-interlacer/scaler to the display.
