Abstract
In a recording and reproducing apparatus having an image sensor which had photoelectric conversion elements arranged in a two-dimensional offset manner and a signal processing part which is arranged to include a two-dimensional filter and a frame memory, a circuit is arranged to enable the two-dimensional filter which forms a luminance signal in recording to be used also for reproduction; and a sampling action for a reproducing operation is arranged t be performed in the form of sub-sampling for every field.
Claims20
A recording and reproducing apparatus having an image sensor which has photoelectric conversion elements arranged in a two-dimensionally offset manner and a signal processing part which is arranged to include a two-dimensional filter and a frame memory, comprising:
- a) a circuit arranged to enable said two-dimensional filter which is arranged to form a luminance signal in recording to be used also for reproduction;
- and
- b) sampling means arranged to perform sub-sampling for every field during a reproducing operation.
A recording and reproducing apparatus comprising:
- a) image sensing means having a plurality of photoelectric conversion elements which are in a two-dimensionally offset structural arrangement;
- b) recording and reproducing means for recording and reproducing an electrical video signal on and from a recording medium;
- c) sampling means for sampling a reproduced output of said recording and reproducing means;
- d) memory means for selectively storing a video signal output from said image sensing means or a video signal output from said sampling means;
- and
- e) a two-dimensional filter arranged to form at least a luminance signal from an output of said memory means.
A recording and reproducing apparatus comprising:
- a) image sensing means having a plurality of photoelectric conversion elements which are in a two-dimensionally offset structural arrangement;
- b) recording and reproducing means for recording and reproducing a sampled video signal on and from a recording medium;
- c) memory means for selectively storing a video signal output from said image sensing means, a video signal output from said recording and reproducing means or a video signal output from a two-dimensional filter;
- d) said two-dimensional filter arranged to perform a filtering process at least on an output of said memory means;
- and
- e) sampling means arranged to sample an output of said two-dimensional filter and to supply the sampled output to said recording and reproducing means or to said memory means.
A reproducing apparatus comprising:
- a) reproducing means for reproducing a recorded video signal;
- b) means for sub-sampling the video signal reproduced by said reproducing means;
- and
- c) signal processing means for processing the reproduced video signal sub-sampled by said sub-sampling means.
