Method and system of processing images for improved display
Image processing may be performed to generate a color image for display on a color display screen and a monochrome image for display on a monochrome display screen, where an overlap of the images may produce a resultant color image at one or more depths. The one or more depths may be determined by an amount of blur applied to one image and an amount of sharpness applied to other. The one or more depths may be determined by a gamma value of the monochrome image. Since the monochrome display screen may have fewer or no color filters and/or a lower resolution, the monochrome display screen may pass more light than conventional color display screens. As such, less light can be used to illuminate color images displayed at different depths using a color display screen and a monochrome display screen, thereby reducing energy consumption of the display device.
