Abstract:
A liquid crystal display device comprising:a controller which converts an original digital image data into converted digital image data in accordance with magnification signals; and a liquid crystal display unit which displays said converted digital image data; wherein said controller comprises: an input unit, which inputs said original digital image data; and a converted image generation circuit, which generates interpolation pixels for interpolating the original digital image data in accordance with said magnification signals, interpolates said original digital image data with said interpolation pixels to generate said converted digital image data, wherein said converted image generation circuit generates as to each of the interpolation pixels, a value representing a gray scale level of said interpolation pixel concerned for interpolating between adjacent two pixels of said original digital image data, by using a first type of interpolation equation which is a linear function specified by the adjacent two pixels when a difference between values of the adjacent two pixels is equal to a threshold or less than the threshold, and by using a second type of interpolation equation which is a curve function specified by the adjacent two pixels when the difference between the values of the adjacent two pixels is larger than the threshold.
