ABSTRACT:
An on-screen edit/display controller has an input unit which is adapted to receive overlaying input data that includes a region header and overlaying image data. The region header defines the location and size of a user-defined region of a display, while the overlaying image data includes mixing weight data and pixel data of a user-defined overlaying image. A mixing unit is adapted to receive pixel data of an original image from an external data source and the overlaying image data from the input unit. The mixing unit is operable in a normal mode, wherein the mixing unit outputs the pixel data of the original image, and a mixing mode, wherein the mixing unit outputs the sum of the product of the pixel data of the overlaying image and a first mixing ratio, and the product of the pixel data of the original image and a second mixing ratio. The sum of the first mixing ratio, which corresponds to the mixing weight data and which ranges from 0 to 1, and the second mixing ratio is equal to 1. An output control unit receives the region header from the input unit and controls the mixing unit to operate in the normal mode when a portion of the display which is outside the user-defined region is being scanned, and in the mixing mode when the user-defined region is being scanned.
