Claim Text:
1. An image processing device, comprising: a plurality of input terminals to which an input image signal is input; contour direction estimating circuitry that estimates a contour direction in which a signal value is a constant value for each of a plurality of pixels; a low pass filter that smoothes the signal value of a pixel of the plurality of pixels based on the signal value of each reference pixel serving as a pixel of a reference region according to the pixel and arranged in the contour direction of the pixel estimated by the contour direction estimating circuitry for each of the plurality of pixels; and parameter deciding circuitry that decides an intensity of smoothing by the low pass filter, wherein the parameter deciding circuitry decides the intensity of smoothing based on a type of the input terminal when a resolution of the input image signal is determined to be unique based on the type of the input terminal to which the input image signal is input among the plurality of input terminals, and the parameter deciding circuitry decides the intensity of smoothing based on a resolution ratio that is a ratio of resolution of an input image signal and resolution of an output image signal when the resolution of the input image signal is not determined to be unique based on the input terminal to which the input image signal is input among the plurality of input terminals.
