Abstract:
1. An image signal processor for processing a main input image signal and a sub input image signal for forming a picture-in-picture PIP image comprising: a first input unit receiving and outputting the main input image signal; a second input unit receiving and outputting the sub input image signal; first and second multiplexers connected to each receive an output of the first input unit and the second input unit; a noise removal unit connected to receive an output of one of the multiplexers for removing noise from an image signal input thereto; a first scaler connected to receive an output of the noise removal unit for scaling an image signal input thereto; a second scaler connected to receive an output of the other one of the multiplexers for scaling an image signal input thereto; and an output multiplexer connected to receive an output of the first and second scaler to provide a main output image signal or a sub output image signal.
