Abstract
An electronic camera having an electronic flash including a plurality of light emitting diodes (LEDs) that emit different wavelength light is disclosed. Electric energy is supplied to a capacitor to the LEDs. A system controller controls light emitting amounts of the LEDs so that a color temperature of the electronic flash light becomes a color temperature that has been manually set with a color temperature setting switch or a color temperature of a light source determined by color temperature sensors.
Claims29
An electronic camera comprising:
- an imager configured to receive ambient light around a subject to be imaged and output color image signals of the received ambient light around the subject;
- a flash light source configured to emit a light, the flash light source adjusting a color temperature of the light to be emitted by a pulse width modulation control;
- an input device configured to choose at least an automatic mode;
- a processor configured to control the electronic camera, the processor performing a white balance control of the color image signals according to a color temperature of the ambient light determined according to the color image signals thereof, adjusting the color temperature of the light emitted from the flash light source to a color temperature that is closest to the color temperature of the ambient light, and controlling a light emitting time of the flash light source, in the automatic mode;
- and
- a monitor configured to display an image according to the image signals subjected to the white balance control.
