MULTIPLE SUB SAMPLE SIGNAL PROCESSING CIRCUIT

摘要

PURPOSE:To provide a multiple sub sample signal processing circuit whose circuit scale is small. CONSTITUTION:The output signal of a signal processing circuit 2 is interpolated in a field by an animation LPF/enhancer 11 and the output signal of a still picture interpolation circuit 5 is still-picture enhanced by the animation LPF/ enhancer 11. The signal interpolated in the field is animation enhanced by an animation enhancer 4 and a mixing circuit 8 proportionately mixes the animation enhanced signal and the still-picture enhanced signal. Since the animation LPF/enhancer 11 is provided with an LPF for limiting a band characteristic to a horizontal frequency 4MHZ, the line memory of the animation LPF and the line memory of the enhancer can be made common and the circuit scale is reduced.
