Abstract: A communication terminal performs a discrete cosine transform and a quantization process in accordance with a selected coding mode so as to reduce loads caused by these processings and suppress degradation of picture quality. When performing coding of a moving picture inputted through a picture input part, a control part determines which coding mode among 4×4 intra prediction coding on a luminance signal, 16×16 intra prediction coding, intra prediction coding on a color-differential signal, and inter prediction coding is performed. In accordance with the selected coding mode, and in view of a predictive error, the processing content in the discrete cosine transform and the quantization process is switched.

Abstract: An information processing apparatus is presented that includes a first determination unit which determines whether a processing target frame is a frame of a predetermined type and a second determination unit which determines whether an interval between the frame and a frame of the predetermined type located temporally nearest in the forward direction, exceeds a predetermined frame count. In addition, a conversion unit is included which converts the processing target frame into a frame of the predetermined type, when the second determination unit determines that the interval exceeds the predetermined frame count.

Abstract: In a moving picture encoding apparatus, a processing load detection section detects a load and outputs load information and a video encoder judges a load level based on the load information. A start pixel in target pixels is determined depending on the load level, the evaluation value is calculated from pixels specified by the start pixel, a encoding cost is calculated based on the evaluation value to select one of prediction modes for minimizing the encoding cost. The start pixel is so selected as to exclude the pixels which are spatially neighboring to reference pixels for prediction, instead of all pixels within a 4×4 pixel block as the processing load becomes large. Thus, the picture processing amount is reducing while suppressing the deterioration of the encoding performance.

Abstract: The optical surface of a lens (21) held and rotated by the rotating shaft (12) of a lathe is cut or ground into an aspherical surface from a direction perpendicular to the axis of the rotating shaft (12) and the axial direction of the rotating shaft (12) while a processing locus (t) which is concentric or spiral about the rotating shaft (12) as the center is formed. In processing, the lens (21) is arranged in a grinding region (20) at a position spaced apart from the turning center (Zo) of the processing locus (t).

Abstract: An object is to reduce the inconvenience given to the binocular vision function when wearing and using spectacles making use of a pair of progressive power lenses having different distance dioptric power for right and left. For this reason, the present invention associates, in a pair of progressive power lenses corresponding to the right and left eyes, an average dioptric power distribution and an astigmatism distribution determined from prescribed dioptric power and a wear state of one of the progressive power lenses with an average dioptric power distribution and an astigmatism distribution determined from prescribed dioptric power and a wear state of the other progressive power lens, and thereby average dioptric power distributions and astigmatism distributions of the respective progressive power lenses are changed.

Abstract: An input image signal is coded by an encoder to be outputted as a basic code string, and the basic code string is delayed by a code-string delay circuit for a predetermined period of time to be outputted as an additional code string. The basic code string is synthesized with the additional code string by a code-string synthesizer to be outputted as an output code string. Thus, there is provided an image data coding system which can quickly restore data even if the data is lost due to error and in which the increased code amount is less than the cycle refresh and the error correction.
