Abstract: In an image-taking apparatus, a main CPU reads a sensitivity level that has been set, thereby determining whether a subject distance measured in AF processing is longer as compared to a threshold. The threshold is variable such that the higher the sensitivity level is the longer the threshold is. When the main CPU determines that the subject distance is longer as compared to the threshold, a metering/distance-measuring CPU causes a first light emitter having a xenon tube to emit light in response to an instruction from the main CPU. When the main CPU determines that the subject distance is shorter as compared to the threshold, the metering/distance-measuring CPU causes a second light emitter having an LED to emit light in response to an instruction from the main CPU.

Abstract: A white light LED flash for a digital camera is described that uses a blue light LED die in conjunction with red and green phosphor or quantum dot material over the LED die. The phosphor or quantum dot characteristics are selected so that the white light substantially matches an ambient light setting in the camera, such as the incandescent ambient light setting. Therefore, when a flash picture is taken under incandescent ambient light, and the flash emits the same type of light as the incandescent light, the flash will effectively brighten the incandescent light. The camera's color compensation algorithm associated with incandescent light illumination is then applied to the photograph and works optimally since the image is only illuminated by incandescent light. This concept is expanded to LED flashes that emulate other types of ambient light having associated color compensation algorithms programmed into the camera.
