    摘要: 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.

    摘要: An electronic still camera comprises a solid state image pickup element including photosensitive elements, a vertical transfer CCD and a horizontal transfer CCD, and a read drive circuit for the solid state image pickup element. Before the start of reading the signal from the solid state image pickup element, at least one pulse is applied to the horizontal transfer CCD to remove electric charges of the interior of the CCD to nullify dark current. The above-described pulse applied to the horizontal transfer CCD before the start of reading the signal from the solid state image pickup element lies in an image pickup period, and the frequency of the above-described pulse of this time is less than the frequency in the read period.
