摘要： PROBLEM TO BE SOLVED: To use a single signal line for plural signals to a switch part by separating the blocks between a switch and a selector in order to write an identification code into each video signal and to sequentially send the video signals to a single output line at the switch side and then to demodulate the identification code and to select and output a desired video signal at the selector side, respectively, thus simplifying the construction work. SOLUTION: A control part 2 generates the switch signals 7 at a time interval that is previously set and outputs the identification codes synchronously with generation of the signals 7. The identification codes are written into the blanking periods of video signals at an addition part 4, and the video signals are sequentially outputted to a signal output line. A reading part 11 reads out the identification codes which are written into the blanking periods of video signals. A demodulation part 13 demodulates the identification codes, and a coincidence selection part 14 confirms coincidence between a desired video signal and its identification code and controls a memory part 12 to output only the desired video signal to a terminal 17. Thus, it eliminates the need for constructing plural video signal input lines in the long distances.

摘要： PURPOSE:To easily set different recording times and to improve the operatbility by constituting the titled method so as to record a picture in changing a picture recording time by depressing a self-timer operating element once or twice. CONSTITUTION:When a self timer button 1 is depressed once during recording stand-by state, an LED display part 2 is made blink by repititious pulses 21 that rises and drops every 250msec starting at a self timer starting point (a), but depressing twice the same makes the display part 2 blink by repetious pluses 25 rising and dropping at every 500msec, both for a duration of T1=10sec. When a point (d) slightly prior to a recording starting point (b) i.e. T1=8sec is used, the generation of the pulses 21 (25) stops, then the LED display part 2 turns off for a time T4=2sec to notice in advance that the recording time soon starts. Then, the display part 2 is turned on by a turn-on signals 22 (26) generated at the recording starting point (b). When the button 1 is depressed only once, the turn-on signal is generated for a time T2=30sec, and the display part 2 ends turning-on when the self timer ends counting, and thus the recording is ended. Also, when the button 1 is depressed twice, the recording state is continued.

摘要： PROBLEM TO BE SOLVED: To make it possible to prevent a picture from distortion by shutter shake in photographing by providing a means for delaying while the shutter shake settles from when a recording start signal from a recording start button enters a CPU until when recording is actually started. SOLUTION: When a photographer presses a photographing button 18 so as to record an image, the recording start signal is fetched by a main CPU 15. After that, just for a time when shutter shake caused by pressing the photographing button 18 settles, the main CPU 15 delays a recording start time, compresses an image by an image compressor 6 after the shutter shake settles and prepares an image compression file. Or, in this case, when delaying, after the photographing button 18 is pressed, a delay circuit for delaying the recording start signal is provided not in the main CPU 15, and it is constituted so that the delayed recording start signal enters the main CPU 15.

摘要： PROBLEM TO BE SOLVED: To allow a user to easily read characters inserted on a video image at all times, regardless of the luminance levels around the characters. SOLUTION: An input video signal A is fed to a switch 5 and a luminance level detection circuit 3. The luminance level detection circuit 3 detects a luminance level at a position of the video signal A, to which a character signal is inserted, compares and discriminates the quantity of the luminance level and a threshold level TL. Then a character signal level variable circuit 4 produces a high level DC voltage E when he luminance level is lower than the level TL and produces a low level DC voltage E, when the luminance level is higher than the level TL and gives the produced voltage to the switch 5. The switch 5 normally selects a video signal B. When a character generator 6 generates a character signal G through the control of a microcomputer 7, the switch 5 selects a signal period of the character signal G and a DC voltage E from the character signal level variable circuit 4.
