Claims
- 1. An image sensing apparatus, comprising:(a) image sensing means including a plurality of photo-electric converting elements for converting image light coming from an object to be photographed into an electric image signal, said photo-electric converting elements being arranged in two-dimensional offset sub-sampling structure arrangement; (b) common memory means for storing an output of said image sensing means; (c) two dimensional low-pass filter means for interpolating the image signal stored in common memory means in a vertical direction and in a horizontal direction and for producing an interpolated image signal; (d) recording or reproducing means for recording said interpolated image signal produced by said two dimensional low-pass filter means on a recording medium or reproducing a recorded interpolated image signal from said recording medium; (e) offset-subsampling means for offset-subsampling the reproduced interpolated image signal reproduced by said recording or reproducing means to thin out said interpolated image signal; and (f) switch means for selectively supplying the output of said image sensing means and an output of said offset-subsampling means to said common memory means.
- 2. An image sensing apparatus according to claim 1, wherein said common memory means has a capacity for storing the image signal for one frame from said image sensing means.
- 3. An image sensing apparatus according to claim 1, wherein said offset-subsampling means includes a switch circuit.
- 4. An image sensing apparatus according to claim 1, wherein said offset-subsampling means performs a two-dimensional offset sub-sampling.
- 5. An image sensing apparatus according to claim 1, wherein said two dimensional low-pass filter means performs interpolation.
- 6. An image sensing apparatus according to claim 1, wherein said reproduced signal is supplied to said two dimensional low-pass filter means to reduce the data amount of said image signal.
