ABSTRACT:
An image pickup device, capable of enlarging images while electronically enlarging the same, picks up images of an object while electronically enlarging the same by two times relative to those in the normal image pickup. In the enlarging image pickup mode, signals having been delayed by a 6H delay circuit are interpolated by a luminance signal interpolating circuit. Horizontal contour of an image based on the interpolated signals is corrected by a horizontal aperture circuit, while vertical contour is corrected by a vertical aperture circuit in response to outputs of the 6H delay circuit. Horizontal contour correcting signals and vertical contour correcting signals are added by an aperture adding circuit. Meanwhile, color-difference signals have their random noises eliminated by a CNR circuit, and are delayed by another 6H delay circuit and interpolated by a color-difference signal interpolating circuit. The interpolated signals are converted by a color-difference signal converting circuit into color-difference signals which are applied to an encoder. For the 6H delay circuit, n/2 CCD 1H delay lines are employed, which can delay the luminance signals or the color-difference signals by n horizontal scanning periods, so that the delay circuit can be reduced in number.
