ABSTRACT:
An image processing apparatus for converting different television standard signals includes an image pickup apparatus for selectively outputting an image signal of one of (i) a first television scheme and (ii) a second television scheme having a larger number of pixels than the first television scheme. An image pickup device is provided having a number of pixels corresponding to the first television scheme. A memory is provided for storing an output image signal from the image pickup device at a frequency corresponding to the first television scheme. An interpolation signal generating circuit is provided for generating an interpolation signal by adding a constant signal to a television signal corresponding to the second television scheme for compensating for an output of the second television signal. Video signal forming circuitry is also provided for forming a video signal by combining the signal read out from the memory and the interpolation signal generated by the interpolation signal generating circuitry.
