摘要:
A digital camera (10) includes a face detecting section (74), a color temperature detecting section (76) and a flash device (86) having an LED array in which RGB LEDs are regularly arranged as a light source. When a shutter button (18) is pressed halfway, the face detecting section (74) reads out image data of a through image from a memory (60) and detects a person's face in the image. A CPU (64) identifies a scene based on brightness values of face and surrounding areas as, for example, a backlit scene, and specifies a face peripheral area according to an exposure pattern corresponding to the backlit scene. When the shutter button (18) is fully pressed, the CPU (64) sends a flash projection command to an LED control circuit (87), thereby illuminating the LEDs corresponding to the face peripheral area. By controlling illumination of the RGB LEDs, the LED control circuit (87) directs to project the flash light having color temperature that corrects the person's face color into an appropriate skin color.
