Abstract
Abstract 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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
253 words
An apparatus for producing a hard copy of a picture, comprising: first input means for receiving a video signal representing a picture which was pickup by a color image pickup device; second input means for receiving data representing picture processing conditions according to which the video signal is to be processed, the data representing picture processing conditions including information relating to the kind of a color separating filter associated with the color image pickup device; picture processing means for processing the video signal according to the data received by said second input means; store means for storing a plurality of groups of color conversion coefficients, wherein each of said groups of color conversion coefficients is associated with a different kind of color separating filter usable with a color image pickup device; picture recording means for recording on a recording medium the picture which is represented by the video signal processed by said picture processing means; and picture display means for displaying the picture which is represented by the video signal processed by said picture processing means; said picture processing means being operative in response to the information included in the data received by said second input means to read a particular one of the groups of color coefficients which is associated with the kind of color separating filter associated with said color image pickup device out of said store means, and for subjecting the video signal to color correction according to the group of color conversion coefficients read out of said store means.
Claim 2
Independent Claim
253 words
An apparatus for producing a hard copy of a picture, comprising: first input means for receiving a video signal representing a picture which was pickup by a color image pickup device; second input means for receiving data representing picture processing conditions according to which the video signal is to be processed, the data representing picture processing conditions including information relating to the kind of a color separating filter associated with the color image pickup device; picture processing means for processing the video signal according to the data received by said second input means; store means for storing a plurality of groups of color conversion coefficients, wherein each of said groups of color conversion coefficients is associated with a different kind of color separating filter usable with a color image pickup device; picture recording means for recording on a recording medium the picture which is represented by the video signal processed by said picture processing means; and picture display means for displaying the picture which is represented by the video signal processed by said picture processing means; said picture processing means being operative in response to the information included in the data received by said second input means to read a particular one of the groups of color coefficients which is associated with the kind of color separating filter associated with said color image pickup device out of said store means, and for subjecting the video signal to color correction according to the group of color conversion coefficients read out of said store means.
