    摘要: When a video signal type detecting section detects a video signal of PAL/SECAM (50 Hz) video signal, the input image data is subjected to enhancing conversion with a degree lower than the degree of enhancing conversion in the case of NTSC (60 Hz). With this, the response speed of liquid crystal is improved and an image noise on account of excessive enhancement is eliminated, so that the deterioration in image quality is prevented. As a result, the enhancing conversion with respect to the input image data is performed in such a manner as to compensate the optical characteristics of the liquid crystal display panel, and an image noise on account of excessive enhancing conversion with respect to PAL/SECAM (50 Hz) image data, and hence high-quality image display is realized.

    摘要: An edge detecting circuit detects whether a particular pixel belongs to an edge by determining whether the differential value of the pixel from the neighboring pixel is equal to or greater than a threshold. Based on the detection result, an emphasis converter stops OS drive when the image of a pixel area is regarded as an edge image in accordance with the detected result of the edge detecting circuit and implements OS drive when the image of a pixel area is not regarded as an edge image. In this way, the edge detecting circuit detects edge portions of the input video, whereby OS drive in the emphasis converter can be controlled so as to be turned on and off.

    摘要: When a video signal type detecting section detects an interlace signal, an I/P conversion section subjects the interlace signal to I/P conversion, and the signal is supplied to an enhancing conversion section. In the enhancing conversion section, the image data is subjected to enhancing conversion, so that optical characteristics of a liquid crystal display panel is corrected. On this occasion, the degradation of the quality of a reproduced image due to the enhancement of unwanted changes (false signal), by causing the degree of the enhancing conversion of the image data having been subjected to the I/P conversion to be lower than the degree of the enhanced conversion of the image data inputted as the progressive signal. As a result, the enhancing conversion of the input image data is performed in such a manner as to correct the optical response characteristics of the liquid crystal panel, so that it is possible to restrain the enhancement of unwanted changes occurring at the outline of the image on the occasion of subjecting the interlace image signal to the I/P conversion, and hence high-quality image reproduction is realized.

    摘要: When receiving an interlaced video signal, an I/P conversion section converts the interlaced video signal into a progressive video signal by any of two or more I/P conversion methods. Further, an emphasis conversion section subjects the progressive video signal to emphasis conversion. Here, a control CPU controls the degree of emphasis conversion performed by the emphasis conversion section so as to be changed in accordance with which kind of conversion method among the two or more conversion methods is used for the conversion. This makes it possible to subject video data supplied to a liquid crystal display panel to emphasis conversion with a degree corresponding to the conversion method. As a result of this, it is possible to implement a liquid crystal display device which can realize both improvement in response speed of a liquid crystal display device and improvement in quality of video image displayed on the liquid crystal display device.
