Japanese Patent JP2615693

B2

PURPOSE:To minimize the deterioration in quality of a picture and to obtain a picture with high quality by detecting the fluctuation among picked-up signals as a moving length, controlling the area to be read of a memory depending on the magnitude of said moving length, and interpolating the signal read out from the memory in accordance with the read area. CONSTITUTION:Picked-up signals from an image pickup element 10 are converted to digital signals by an A/D converter 11, and signals equal to one-field length are written in the memory 12. Simultaneously to the memory 12, the signals are inputted to a moving length detecting circuit 14, where a moving length is obtained by representative point matching method. By using thus obtained moving length, a cutting-out size control part 50 determines the cutting-out size of an image from among the image signals written in the memory 12. Through this moving length and the position of scanning Ix, Iy within the cutting-out size, a moving length control circuit 17 obtains the read address of the memory 12. And the signals read out from the memory 12 are interpolated by an interpolation circuit 13, and outputted as one signal. As a result, the deterioration in resolution can be suppressed at minimum, and the sufficient correction of the fluctuation of the picture and the high quality of a picture are made compatible.
