Filed: 1995-05-01
Abstract: PURPOSE: To obtain a sharp image by applying image processing to image data whose gradation level is a prescribed level with a quadratic differentiation operator and adding a prescribed natural number to the gradation level of each picture element to the sum to a prescribed range thereby reducing a thermal history of a heat generating element. CONSTITUTION: A video signal separated into a luminance signal and a color difference signal is quantized by an A/D converter 13, in which the video signal is converted into a digital signal with, e.g. 256 gradation number. The digitized luminance data and color difference data are written in an image memory 14. The data read from the memory 14 are given to a color adjustment circuit 15, in which color correction is executed. The luminance data and color difference data given from the circuit 15 to a thermal history correction section 16 are corrected by an approximated equation using a quadratic differentiation operator. A value 128 is added to a gradation level subject to correction.  Then a gradation level of a picture element whose gradation level is 0 or below is set to 0, a gradation level of the picture element with 512 or over is set to 511 and the picture element with an intermediate gradation level is not modified. Thus, the gradation number of the luminance data and color difference data is converted from 256 into 512 gradation number.

Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To enable transportation of steel to be freely changed over in forward and backward directions by providing a locking mechanism for two pawls for transporting forward and backward in the manner that, with one pawl standing up, the other falls down and that, with one pawl falling down, it is prevented from standing up.
