    摘要: An electronic flash light is emitted from a camera by causing light-emitting diodes corresponding to red, green and blue simultaneously. Light emission of the light-emitting diodes corresponding to respective colors is controlled in accordance with the light-receiving characteristics of the light-receiving elements. For example, by adjusting the on and off duration ratio of switches in accordance with the light-receiving characteristics, the quantity of light emitted by the light-emitting diodes is adjusted.

    摘要: Electronic equipment includes a processing unit which controls light emission from LEDs by referring to music data described in a music file such as a MIDI file. The processing unit controls light emission from the LEDs by detecting the occurrence of sound described in the music file. Light emission from the LEDs may be controlled in accordance with tone data and/or a track number included in the music file. Alternatively, light emission from the LEDs may be controlled in accordance with volume data.

    摘要: Light-emitting parts are attached to a light guide plate of a backlight unit so as to be illuminated by the backlight. A measuring unit formed by light-receiving parts is provided on the opposite side of the light guide plate. The measuring unit detects the luminance or color tone of light inside the light guide plate. A control unit subjects the luminance or color tone to feedback control in accordance with a result of measurement.

    摘要: A booster converter outputs a boosted voltage. A plurality of LEDs emit light of respective colors. The transistors establish or shut connection between the LEDs and a main driving circuit. A variable current circuit feeds a current to drive the LEDs. A PWM control unit effects control to cause the LEDs to emit light with respective tones of color. A PWM circuit executes PWM modulation in accordance with an instruction from the PWM control unit. A setting control unit 138 controls the magnitude of the driving current fed by the variable current circuit in accordance with an instruction from a second light emission control unit. In an image pickup mode, an additional driving circuit feeds a driving current to the LEDs so that the LEDs operate as an electronic flash.
