An apparatus for producing a hard copy of a picture picked up by a color image pickup device processes a video signal representing the picture according to data representing picture processing conditions entered by a data input unit. The data relates to the kind of a color separating filter associated with the image pickup device. A storage has groups of color conversion coefficients stored therein, each of which group specifies color conversion associated with the kind of a color separating filter, in accordance with the data relating to the kinds of color separating filters which are usable with image pickup devices. The picture represented by the processed video signal is recorded on a recording medium and displayed on a picture display. In response to the data received by the data input unit, a particular one of the groups of color conversion coefficients which is associated with the received data is read out of the storage, and the video signal is subjected to color correction according to the group of color conversion coefficients thus read out.
