Abstract:
An imaging parameter recording apparatus and an imaging apparatus are disclosed. The setting states of various parts of an imaging system 1 at the time of imaging are detected by a system controller 9 and routed as imaging parameters to a recording/reproducing system 2. These imaging parameters are recorded along with the imaging data on a video tape 17. This enables not only the picture corresponding to the imaging data but also the imaging parameters at the imaging time to be reproduced at the reproducing time, so that not only the past setting state can be recognized, but also the past setting state can be newly set so that the picture of the same picture pattern can be imaged.
Abstract:
An aperture correction circuit adds to the input video signal an aperture correction signal formed from the input video signal and which is subject to non-linear processing to thereby effect the aperture correction for a picture of low or high contrast.
Abstract:
In a micro-processor based automatic registration compensation system for a multi-tube color television camera, the number of correcting points is increased by interpolation of a limited number of sampled error data. The sampling of errors, and generation of respective registration compensating signals therefrom are effected twice in respect to errors in the vertical direction and four times in respect to errors in the horizontal direction for video signals from a red pick-up tube and a blue pick-up tube, respectively, relative to a video signal from a green pick-up tube. The registration compensating signals thus obtained, particularly for the horizontal errors, are desirably applied to auxiliary deflection coils provided on each of the red and blue pick-up tubes.
