Patent number: 7480454Abstract: Mobile equipment includes LEDs supplied with a current to emit red light, green light and blue light, FETs and a booster circuit for controlling the current supplied. The current supplied is controlled to supply all of the LED with a current of a low level to illuminate an object in a shooting mode with light for illumination. Thus in the shooting mode a white spot light illuminates the object, and the object can clearly be confirmed. At the moment of shooting, a current supplied can be increased at a burst to emit white flashlight to illuminate the object. A satisfactory image can thus be obtained. The source of light for illumination can be formed of miniature, light-weight LED, and does not impair in mobility mobile equipment having the source of light incorporated therein.Type: GrantFiled: August 27, 2007Date of Patent: January 20, 2009Assignee: Sharp Kabushiki KaishaInventor: Kouji Yamashita
