Title: Parameter curved line generator
Inventor: KAI NAOYUKI
IPC: G06T11/20
Filed: 1988-12-28
Abstract: PURPOSE:To generate a desired parameter curved line at high speed in a ratio of one point to two clock cycles on the average by performing a bi-secting operation on the control point of a Bezier curved line supplied to a register in advance repeatedly. CONSTITUTION:The x-coordinate and y-coordinate of each control point of the curved line to be generated are set on a parameter curved line generator. After that, the x-coordinate and the y-coordinate of the each control point of the Bezier curved line divided sequentially are held at a register 11. A bi- secting circuit 12 generates each control point of two pairs of Bezier curved line by performing the operation of a calculation equation to compute the control point Pi' and the control point Pi''. A stack memory 13 holds each control point of the Bezier curved surface on one side of the two pairs generated at the circuit 12. A judging circuit 14 checks the extent of the division of the Bezier curved line based on the content of the register 11, and judges whether or not bi-secting should be continued further. In such a manner, the desired parameter curved line can be generated by performing the bi-secting operation on the control point of the Bezier curved surface repeatedly.

IPC: H04N5/217
Filed: 1988-12-29
Abstract: PURPOSE:To obtain a picture signal from which high frequency noise is reduced or eliminated without giving a fog to the edge of a picture by taking a difference of an original picture signal to form a difference signal, reducing and eliminating the high frequency noise included in the difference signal without giving a fog to the difference signal and forming a picture signal from the corrected difference signal. CONSTITUTION:An MPU 1 reads a data comprising (n+1) sets of picture signals digitized by an A/D converter 3 and obtains a difference signal by making the data correspondent to each picture element of a sensor 5. Then if a difference signal is comparatively small and whether or not a difference signal with nearly equal to an absolute value and a different sign exists in the vicinity of the former difference signal are checked and when the signal exists, they are cancelled to make the difference signal zero. A picture signal is obtained from the difference signal corrected in this way. That is, the difference signal is reduced or eliminated without giving a fog to the difference signal and the picture signal is obtained from the corrected difference signal. Thus, high frequency noise is reduced or eliminated without giving a fog to the edge of the picture.
