Abstract: 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.

Abstract: 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.

The control unit is adapted to determine the search precision on the basis of a pixel structure of a display device for displaying the progressive scanning picture.

Abstract: The generation of thumbnail images from encoded image data at high speed is carried out. In decoding encoded image data, without performing inverse DCT, only the DC coefficient among the DCT coefficients of each block is extracted. For an I picture, the DC coefficient is outputted as decoded data on the corresponding block. For a P picture and a B picture, a motion compensation value calculated based on the corresponding motion vector is added to the DC coefficient and the sum is used as the pixel value of the corresponding block. The calculation to be made for motion compensation can be greatly simplified by reducing the motion vector accuracy to an eight-pixel accuracy (an accuracy corresponding to a unit of a block), making it possible to generate thumbnail images at high speed.
