ABSTRACT:
Solid-state imaging elements each having a smaller number of pixels are employed to realize an imaging device for taking a high-definition picture which is four or more times larger in the number of pixels than each of the solid-state imaging elements, and also an apparatus for recording/playing back (or transmitting) the high-definition picture. A two-dimensional space which includes, at least, nH spatial sampling points in a horizontal direction and nV spatial sampling points (nV lines) in a vertical direction, totaling (nH.times.nV) spatial sampling points, is imaged under the condition that light is sensed at, at most, 1/2 of the sampling points of the two-dimensional space. Thus, the imaging device delivers as its output a video signal containing effective pixel information items which correspond to the light-sensed sampling points and which are, at most, (nH.times.nV)/2 in terms of the number of pixels.
