<p>Process for partial electronic retouching during the reproduction of colour images. The sampling point by point of the image and the analog-digital transformation provides values representative of colours. These values representative of individual components of colours are stored in a memory (1). For each colour component to be retouched, a colour increment is determined independent of the location which represents at that moment the smallest variation to be brought to the colour representing value. When, for each point of image to be retouched, the retoucher engages a probe (51) of an acquisition device for recording coordinates to mark the point, a retouching factor depending on the location will be searched translating the magnitude or extent of the retouching by a numeral giving the number of increments of the value representative of the colour to be added or subtracted for each point. A correction value depending on the point and individually for each point will be calculated from the colour increment and the retouching factors. For the control, the retouched and non retouched images will be represented on a monitor. </p> |
