摘要： An n-filter according to the present invention includes a nonlinear filter, a pattern detector, and a switch. The nonlinear filter maintains a steep edge whose size is larger than a predetermined threshold in fluctuations of pixels constituting an input image signal and, at the same time, smoothes a non-edge portion that does not include the edge. The pattern detector detects a fine edge in the fluctuations of the pixels constituting the input image signal and notifies the switch that the fine edge exists. The switch outputs the input image signal or an image signal output from the nonlinear filter to the subsequent stage in accordance with the notification from the pattern detector.

摘要： The present invention relates to a display control apparatus and method, and a program which make it possible to suppress deterioration in the image quality of an image.A backlight luminance calculating section (121) finds the backlight luminance of light to be radiated by a backlight, on the basis of the image signal of an image. A subtraction section (142) finds the difference between the backlight luminance from the backlight luminance calculating section (121), and a backlight luminance from an addition section (141). A multiplication section (143) multiplies the found difference by a cyclic coefficient indicating the degree of contribution of the difference to correction of the backlight luminance, obtaining a correction value. The addition section (141) adds the correction value to the backlight luminance to correct the backlight luminance. Also, from the image signal and the backlight luminance, a division section (124) calculates the transmittance of light in a liquid crystal panel that displays an image by transmitting light from the backlight. The present invention can be applied to a liquid crystal display apparatus.
