Patent

CA 2737184

An apparatus and method for capturing an image on a mobile device (100) having a flash module (200) comprising a red light source (204) and a white light source (202) is presented herein. A detection of a color spectrum of ambient light (160) is made using image data sensed by an image sensor (210). Additionally, a determination of an intensity of red light when combined with an associated intensity of white light results in a color spectrum that substantially matches the color spectrum of the ambient light (160). The flash module (200) emits white light from the white light source (202) of the flash and red light from the red light source (204) of the flash module (200). An image from a camera module (220) is recorded during the emission of the white and red light.
