Filed: 1992-11-27
Abstract: PURPOSE:To provide a digital X-ray photographing apparatus wherein regeneration of photographed image data which an operator requires during IVR can be immediately performed. CONSTITUTION:An X-ray photographed image is fed to an image treating part 10 and is recorded and collected in a magnetic disc apparatus 11. The photographed and collected photographed image data are regenerated on monitors 12 and 13 for photographing. This regenerating photographed image data can be selected and indicated by means of joy sticks 21 and 22. On monitors 15 and 16 for sight through, a menu screen indicating treatments which can be performed by using the joy sticks 21 and 22 and a sight-through screen are displayed by switching. An operator selects and indicates the photographed image data which he wishes to regenerate by using a joy stick 21. If necessary, the second menu screen is displayed on the monitor 15 for sight through and such a treatment as enlarged display of the regenerated image is selected.

Title: Picture-recording-state discriminating device for video tape
Inventor: ZEN HEIKOU
IPC: H04N5/93
Filed: 1992-12-22
Abstract: PURPOSE: To enable automatically discriminating a video recording state of a tape by A/D converting a DC component of an envelope signal, obtaining a mean value and comparing it with a reference value every occurrence period of a head switching pulse. CONSTITUTION: The envelope signal of a video signal is converted to a DC voltage by DC converters 4, 5 to be A/D converted by sampling frequencies from AND gates 18, 19. Then, an average means 23 divides the signals sampled during one frame by the sampling frequency to calculate the mean value. A comparison means 25 compares the mean value with the reference value from a reference value update means 27, and displays it on a display part D whenever the mean value lower than the reference value occurs to update the reference value with the mean value. Thus, the display value of the display part D is kept always to the lowest value, and the defective video recording state of a video or an audio on the tape is discriminated from this value.
