Abstract: In a display control circuit of this invention, a write gray scale level determining part outputs write gray scale level data for performing overshoot drive on a liquid crystal display device. Moreover, an achievable gray scale level determining part outputs achievable gray scale level data indicating a gray scale level which achieves after a lapse of one frame. Further, an error noise predicting part compares, with a predetermined threshold value, predicted values as differences between gray scale level values of plural pieces of input image data and a mean gray scale level value of these gray scale level values to control a data selecting part such that when at least one of the predicted values exceeds the threshold value, the data selecting part gives, to an image compressing part, the input image data rather than the achievable gray scale level data predicted that a decoding error becomes large. This configuration allows suppression or elimination of after-image noise.

Abstract: The vector detecting unit detects a motion vector even for a block that is encoded in the intra mode, and the detected motion vector is stored in the reference vector storing unit. Even for a block that has been encoded in the intra mode, the initial vector calculating unit calculates an initial point with the use of a reference vector, the initial point serving as an initial point used in a motion vector detection process during hierarchical block matching. Thus, it is possible to calculate an initial point with a high precision level with the use of motion information from the vicinity of a target block for which a motion vector is to be detected.

Abstract: A series of transmission gears use an internally meshing planetary gear structure. The structure has a first shaft, eccentric bodies provided on the first shaft, and external gears mounted on the eccentric bodies through bearings. An internal gear internally meshes with the external gears, and a second shaft is connected to the external gears through means for transmitting only the rotational component of the external gears. The series includes a group of sub-series of the transmission gears, including transmission gears which are different from each other in a speed change ratio within a range from a low speed change ratio to a high speed change ratio, and which are the same in the mating dimension for installation to a mating machine. The transmission gears in the same sub-series include a type of transmission gears of a low angular backlash type which do not reduce the angular backlash. Each type of transmission gear has a same speed change ratio, a same mating dimension, and a same transmission capacity.
