Title: Automatic discrimination and conversion circuit of polarity of horizontal and vertical synchronizing signal
Inventor: OIDE TAKAHIRO
IPC: H04N5/04
Filed: 1985-05-07
Abstract: PURPOSE:To allow a display device to receive a signal even with both positive and negative logic by discriminating automatically the polarity of a horizontal synchronizing signal and a vertical synchronizing signal of an input video signal so as to convert the output or polarity. CONSTITUTION:Suppose that the horizontal and vertical synchronizing signals are sent from an input terminal 1 by positive logic and the inside of the display device receives a signal with negative logic only. In case of a signal with a large duty ratio, it is integrated by a resistor and a capacitor and a comparator 2 compares it with a preset reference voltage so as to obtain the polarity of the inputted signal. The time constant CR is set to a value for larger than the period of the input signal. When the level of the output of the comparator 2 is logical H, the logic of the input signal is negative and when the output level of the comparator is 'L', then it is represented that the positive logic is used. In this case, the output of the comparator 2 is logical H. An XOR logic circuit 3 ORs exclusively the said signal and the input signal to convert the input signal into a required polarity.

Title: Binarization method of fringe pattern projected picture for shape measurement
Inventor: UEDA KENJI
IPC: G06T7/00
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To process data in a short time without limiting the measurement object by dividing the pattern into the rage in which at least one bright fringe is included in every scan line and binarizing the fringe image which the range using the binarization threshold value which is set for every range. SOLUTION: When the binarizing process of the fringe image having bright and dark fringe patterns formed by plural slit light beams is performed, the process is conducted by the binarzation threshold value having a fixed strength. Then, the widths of bright fringes become smaller as the fringes move from the center to the outer side and all fringes, which have luminance values less than a threshold valued disappear. Then, when the measurement of a shape is implemented by detecting the position of the fringes, an erroneous detection or a measurement unable case occurs. Therefore, the fringe picture data are divided into the ranges (for example, 50 pixels) so that at least one each of bright and dark fringes are included for every scan line and a binarization threshold value is determined for every ranges from the maximum and the minimum luminance values of each range.  When the fringe picture in each range is binarized using the threshold value, the variation in the widths of fringes caused by the unevenness in brightness is reduced and the binarization process is accurately performed.

Title: Communication controller
Inventor: KAMIYAMA TOSHIHIRO
IPC: H04L69/14
Filed: 1982-06-07
Abstract: PURPOSE:To avoid the overlapping between control and program writing, by performing program writing to its own line after the maximum required time of control is elapsed, after a request for suppressing the control to other lines is set in a request suppressing means. CONSTITUTION:The communication controller consists of a line connecting section, an execution controlling section, a connection controlling section and a memory. When a requst of program writing to its own line is generated, the execution controlling section sets a request suppressing circuit 3 of the line connection section with a command. If no DMA execution signal 38 is outputted in this case, a control circuit 5 outputs a suppression signal to invalidate DMA request signals 31-34 from a serial input/output controller 1. After the circuit 3 is set and the maximum required time of DMA is elapsed, the execution controlling section executes the program writing. Even if the setting of the circuit 3 and the start of DMA are done at the same time, the overlapped execution of the DMA and the program writing is avoided through the waiting of the maximum required time of the DMA.
