IMAGE DISPLAY DEVICE AND METHOD FOR DETERMINING CHARACTERISTICS OF CONVERSION CIRCUIT OF THE IMAGE DISPLAY DEVICE, IN WHICH VERTICAL SCALING FILTER CHARACTERISTIC IS CHANGED ACCORDING TO A SELECTED SCAN METHOD

摘要

PURPOSE: An image display device and a method for determining characteristics of a conversion circuit of the image display device are provided to have good image quality by providing optimum vertical space frequency response characteristics. CONSTITUTION: A switching signal(S12) switches a conventional scanning and an interlacing scanning. A resolution conversion unit(7) performs magnification and reduction of an image size. A driving control circuit unit(6) outputs a scanning control signal(S10) according to the switching signal. A resolution conversion control unit(12) outputs conversion parameter(S6) appropriate for each mode of the conventional scanning or the interlacing scanning.
