Title: Correcting method for vision sensor
Inventor: SUMIDA TATSUO
IPC: G06T3/00
Filed: 1990-02-05
Abstract: PURPOSE:To correct the distortion of a picture by calculating difference between a parallel line interval to be obtained at a position, where the distortion of the picture is least, and a parallel line interval in a scanning direction, calculating the moving amounts of picture elements from the difference and the coordinate values of the picture elements and moving the picture elements backward. CONSTITUTION:The parallel line interval near the picture, where the distortion of the picture is a little, is subtracted from the parallel line interval obtained by scanning picture data, and difference (c) of a parallel line interval (b) is calculated and written into a correction memory. In order to calculate the moving amounts of the picture elements from the value of this difference (c), a position is decided as the reference of movement in the picture data related to scanning. Assuming a moving amount (d) is 0 at the reference position, a point obtaining the difference of the parallel line interval is searched from the reference position to the end of the picture. When the value of the calculated moving amount (d) for each picture element is positive, the picture elements are moved so as to approach the reference position, and when the value is negative, the picture elements are moved so as to be separated from the reference position. Thus, the picture distortion can be corrected.

Filed: 1982-02-22
Abstract: PURPOSE:To give the titled transistor the characteristics thereof will be applicable to the manufacture of super high speed transistor and an extra high speed integrated circuit by a method wherein AlAs is used instead of AlxGa1-xAs in order to prevent the lowering of electronic mobility due to the clustering in AlxGa1-xAs. CONSTITUTION:The point which is different from the structure heretofore in use is that AlAs is used instead of AlxGa1-xAs. In the same manner as in the case of structure heretofore in use, a two-dimensional electron gas layer 8 is formed in the vicinity of the AlAs/GaAs hetero interface. Moreover, as the AlAs layer is a two-element III-V group compound semiconductor, it has no clustering generating from mixed crystal as in the case of AlxGa1-xAs. Accordingly, the scattering of electron on the hetero interface is reduced, and a high-speed electrostatic transistor, which is higher in speed than AlxGa1-xAs/GaAs HEMT, can be manufactured. The thickness of a non-doped high purity GaAs layer 2 is 0.5-1mum, a non-doped AlAs layer 3a is 50-100Angstrom , an Si doped N type AlAs is 1-0.5mum, and the carrier density is 0.5-2X10<18>cm<-3> or thereabout.
