PRE-IMAGE CAPTURE COLOR EFFECTS

摘要

A system and method for apply color effects to a digital camera is described. The system comprises a controller 220 communicatively coupled to an image sensor 222. The controller 220 generates and processes a plurality of color images. The controller comprises a camera control unit 224 that receives at least one color effect parameter and stores a plurality of RGB bias values corresponding to the different color effects. A camera processing unit 226 is communicatively coupled to the camera control unit 224 and receives 422 the color effect parameter and the color image. The camera processing unit is configured to convert 424 the color images to a plurality of gray scale images, and apply 426 the RGB bias values to the gray scale images to generate modified images having the color effect associated with the color effect parameter. A preview mode displays 428 the modified images before the modified image is captured in a non-volatile memory.
