ABSTRACT:
An image signal processing circuit according to the present invention comprises an image signal processing unit, a line memory, a logic unit, an output pad and a data replacing unit. The image signal processing unit generates image data from an inputted image signal. The line memory temporarily memorizes the image data per line and outputs the memorized image data while switching to and from effective and ineffective. The logic unit generates digitally processed image data by digitally processing the image data outputted from the line memory. The output pad outputs the digitally processed image data. The data replacing unit generates dummy data and replaces data in a data region set as ineffective by the line memory among the image data outputted from the line memory or the digitally processed image data outputted from the logic unit with the dummy data.
