Abstract
Image quality adjustment of an inputted image signal is performed with higher accuracy to display a more preferable image to the user. An attribute information determining unit obtains first attribute information indicating the format of the inputted image signal and second attribute information indicating transmission characteristics of the image signal. An image quality adjustment value calculating unit calculates optimal image quality adjustment values for the image signal from the obtained first and second attribute information. An image processing unit adjusts the image quality of the image signal based on the optimal image quality adjustment values and then outputs the image to an image display. The second attribute information includes the bit rate, resolution, and frame rate of the image signal.
