Color conversion image processing system with modified intensity information calculation

摘要

An image processing system changes the color of a portion of an image to another color while maintaining the shades of the original image and which can also implement color changes between the three primary colors. The system utilizes a calculator which calculates modified intensity information from intensity information of color components read out from an image memory. The modified intensity information or the intensity information read out from the image memory is selected by a selector and fed to a look-up table memory through a gate. The look-up table memory converts the modified intensity information or the intensity information to converted intensity information in accordance with a predetermined function. A display displays an image on the basis of the converted intensity information outputted from the look-up table memory.
