摘要： An object of the present invention is to provide a technique of appropriately compensating for loss of even an entire image frame due to data error such as a transmission error to allow display of a high quality image. An image display apparatus of the present invention comprises: a decoding unit which decodes an encoded bit stream into an image signal; an interpolation image generating unit which generates an interpolation frame based on frames of the decoded image signal; and a control unit which detects an error in the encoded bit stream and controls the interpolation image generating unit; wherein when a frame of the encoded bit stream is lost (that is, it has not been able to be decoded) due to an uncorrectable error, the above interpolation frame is displayed instead of the lost frame.

摘要： A disclosed technique for adjusting the image quality uses a moving picture for a sample stored in advance on a storage medium. A plurality of sample moving picture images, based on the moving picture for a sample read from the storage medium, having different image quality relative to each other are displayed on the screen. This technique enables confirmation of how the actual image having been subjected to the image quality adjustment would be displayed in an apparatus for displaying a moving image, such as a television receiver, because the sample stored on the storage medium is a moving picture.

摘要： In a cellular phone terminal, a bit error rate measurement section measures a bit error rate of broadcast data received by a broadcast reception section for receiving a digital broadcast to output broadcast data while a transmission operation of a communication transmission section for wirelessly communicating with a broadcasting communication network is performed. When the measured bit error rate is equal to or higher than a predetermined threshold, stopping of the transmission operation of the communication transmission section is instructed. Thus, a failure such as interruption of television broadcasting reproduction can preliminarily be prevented by avoiding error occurrence in reception of the 1 segment broadcasting service due to an influence of a transmission electric wave in data communication. As a result, stable reception of the 1 segment broadcasting service can be executed.

摘要： A sub-field lighting image display apparatus according to the present invention improves a dynamic false contour, motion judder, and the like occurring when displaying an image to which frame rate conversion is applied. A frame rate conversion section converts a frame rate for an input image. A motion vector detection section detects motion vector V0 between frames in the input image and finds motion vector V after the frame rate conversion based on the detected motion vector V0. When the frame rate conversion section repeatedly outputs the input image as an interpolation image, a motion vector correction section corrects the motion vector V to V1 using V1=V×α, where 0≦α

摘要： The present invention relates to a technology of appropriately improving image resolution. According to an image signal processing method of the present invention, an input video signal contains an image signal whose pixel size is converted at a specified magnification scale. The input image signal is used to calculate sampling frequencies for image signals before and after the pixel size conversion. A ratio of sampling frequencies before and after the pixel size conversion is used to determine the specified magnification scale. A sampling phase for the image signal before the pixel size conversion is calculated from the input image signal after the pixel size conversion. A sampling carrier for the image signal before the pixel size conversion is generated from the sampling frequency and the sampling phase both before the pixel size conversion.
