Abstract

A portable electronic communication device includes an image memory that stores an image in its original colors; a display that presents the image, in its original colors, when received from the image memory, based on an instruction, received from a user of the portable electronic communication device, to present the image without adjustment to the original colors; and a white balance adjustment device including multiple image signal adjusters that adjust signal levels of image signals corresponding to particular colors, where, when another instruction is received from the user to adjust the original colors, the white balance adjustment device controls the multiple image signal adjusters, based on user input, to select color adjustments and apply the color adjustments to create a color-adjusted image. The portable electronic device also includes another memory that stores the color-adjusted image, where the display is configured to present the color-adjusted image when received from the other memory.
