The image processing circuit has a first scaling circuit, a plurality of line buffers, a first sharpness circuit, a second scaling circuit, and a second sharpness circuit. The first scaling circuit enlarges an input image along a first direction to generate a first enlarged image. The line buffers temporarily store the pixel values of a plurality of pixel rows of the first enlarged image. The first sharpness circuit vertically sharpens the first enlarged image to generate a first sharpened image. The second scaling circuit enlarges the first sharpened image along a second direction to generate a second enlarged image. The second sharpness circuit horizontally sharpens the second enlarged image to generate a second sharpened image. Accordingly, it is possible to use the line buffers having shorter data lengths to perform the vertical sharpening.

摘要： A circuit for detecting motion pictures includes a first-stage motion picture detecting unit and a second-stage motion picture detecting unit. The first-stage motion picture detecting unit analyzes a current image frame and a previous image frame to calculate a first motion value associated with the current image frame. The second-stage motion picture detecting unit receives the first motion value, compares the first motion value against an adjusted motion value, and outputs and stores a larger one as a second motion value. The adjusted motion value is a value derived by adjusting an adjacent previous second motion value.
