Abstract:
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.
