Abstract:
1. An image-signal processing device comprising: an image-enlargement processing unit configured to generate image signals representing an image that has been enlarged by repeating pixels; a pattern-data output unit configured to output, for each of repetition areas that are obtained by repeating the pixels, a pattern data item in accordance with signals that are obtained by removing signals corresponding to a predetermined number of upper bits from a corresponding one of the image signals, the pattern data item being used to reproduce, in the pixels included in the repetition area, gradation based on the signals that are obtained by removing the signals corresponding to the predetermined number of upper bits from the image signal; and an addition unit configured to add, for each of the repetition areas, the pattern data item to the signals corresponding to the predetermined number of upper bits included in a corresponding one of the image signals, wherein when the number of bits corresponding to the signals that are obtained by removing the signals corresponding to the predetermined number of upper bits from the image signal is set to m, the number of pixels included in the repetition area is “2
