IPC: H04N5/91
Filed: 1994-03-09
Abstract: PURPOSE: To provide a video modulation synchronizing method using a constant time base. CONSTITUTION: Continuous pixels expressing the video data of a continuous line for raster scanning are buffered, phase adjustment between a synchronizing signal of a specific level and an adjacent system clock signal having specific frequency is found out and real phase adjustment and predicted phase adjustment between the final pixels of respective lines are found out to find out a phase adjustment difference between the start and end of each line. The phases of respective continuous pixels for system clock signals are gradually adjusted in accordance with the number of system clock signals in the line and the phase adjustment difference and the pixels of the video data are synchronized with respective system clock signals.  When practical phase adjustment with a system clock signal is determined at the end of each line, the phase adjustment between the start and end of the line is determined from the phase adjustment of the line and the stored phase adjustment of the preceding line, and when predicted phase adjustment at the end of each line is executed, the estimated value is changed in each line only by quantity equal to the real phase adjustment at the start of the line and the estimated phase adjustment at the end of the line.

Title: Phase compensating circuit
Inventor: ATOBE MASAAKI
IPC: H03H7/20
Filed: 1986-02-25
Abstract: PURPOSE:To improve reliability of the titled device with use of a phase demodulating device, etc. by compensating the pass phase fluctuation which is produced by the frequency fluctuation of the signal wave when the signal wave having the frequency fluctuation passes through a circuit having a delay time. CONSTITUTION:The signal outputted from a terminal 112 is compared with the signal output emerging at a terminal 201 through a variable phase circuit 22 by a phase comparator 21. Thus the phase difference between these signal and output is detected and fed back to the circuit 22. As a result, the phase of the signal outputted to the terminal 201 is controlled to be approximately equal to the phase outputted to the terminal 112. Furthermore a proper amplifier circuit is set between the comparator 21 and the circuit 22 to amplify the output of the comparator 21. This improves the compensating characteristics for the pass phase fluctuation.

IPC: G03B13/12
Filed: 1987-02-20
Abstract: PURPOSE:To obtain high optical performance with which the diopter of a finder image can be maintained in a specified position by fixing respective lens groups and changing the refracting power of the prescribed lens group. CONSTITUTION:The finder image 6 is observed by an eyepiece lens 4 through a Porro prism 5. The variable power of the finder magnification is executed by changing the refracting power of the refracting power variable lens in the 1st lens group 1 and the 2nd lens group 2. For example, both the 1st lens group 1 and the 2nd lens group 2 are fixed and the refracting power of the refracting power variable lens is changed, by which the 1st lens group 1 is weakened in the negative refracting power and the 2nd lens group 2 is weakened in the positive refracting power. The finder magnification is thus changed from the low to the high power. The prescribed variable power ratio is thereby easily obtd. and the maintenance of the diopter at the specified position is permitted. The high optical performance is thus obtd.
