Abstract

A camera comprises a lens and an LED array at its front. The LED array is composed of red, green and blue LEDs (2, 3, 4), which are individually turned on and off for light emitting purposes, as well as changeable in their quantities of red, green and blue lights to be emitted under control of an MPU (7). Thus, the LED array is capable of emitting light having any color having a different brightness by controlling the respective quantities of red, green and blue lights to be emitted by the corresponding LEDs (2, 3, 4). That is, the camera is capable of irradiating an object with light having a desired color for image pickup.
