Abstract: PROBLEM TO BE SOLVED: To attain a shape operation with a small memory quantity by calculating the inclination of a relative face and the distance of pixels in the depth direction from the ratio of luminance values between adjacent pixels. SOLUTION: The luminance values of respective pixels are mutually compared and a face including a pixel having the maximum luminance is selected as reference face A.

Then, a face B adjacent to the face A is determined and the relative ratio of intensity of reflected light is determined based upon the ratio of the luminance of the face B to that of the face A. Then, the angle of the intersection line of the faces A, B is measured from picture data. A part having a large luminance change is detected as the edge of the face and the inclination ηof the edge is found out. Then, the normal vector (m) of the face B is found out by a prescribed equation.  Then, the face A and the vector (n) are respectively substituted for the face B and the vector (m) and the processing of a face adjacent to the new face A is repeated to recursively calculate the angle of the face.

Abstract: PURPOSE:To surely and accurately extract a desired data and to attain picture reproduction without position fluctuation by replacing a video signal read from a memory into a composite synchronizing signal generated by a reference synchronizing signal generator. CONSTITUTION:When a blanking signal BLNK is fed to a switch 16, it is thrown to the position of Y to select a composite synchronizing signal CSYNC. Thus, a composite synchronizing signal CSYNC is outputted from an output terminal 12 in place of a horizontal synchronizing signal of a video signal Vout, a vertical synchronizing signal and an equalizing pulse. Thus, the composite synchronizing signal CSYNC of the video signal Vout is replaced into the composite synchronizing signal CSYNC synchronously with it and a horizontal synchronizing signal and a vertical synchronizing signal with excellent waveform in the video signal Vout obtained at the output terminal 12 are set at a correct position. Thus, the deviation in the vertical direction of a reproduced picture is prevented on the monitor screen and a desired data added in a vertical blanking period of the video signal Vout is surely and accurately extracted.
