Abstract
The present invention provides a camera having strobe unit, comprising a strobe flashing unit for emitting illumination light toward an object, a switch for switching states of flashlight emanating from the strobe flashing unit by selecting normal flashlight or flashlight that is effective in alleviating a red-eye phenomenon and that contains less red light than normal flashlight, an information recorder for recording photographic information on film, and a recording control unit for allowing the information recorder to record flashlight selected by the switch.
Claims20
A camera having a strobe unit, comprising:
- a strobe flashing means for emitting illumination light toward an object;
- a switching means for switching states of flashlight emanating from said strobe flashing means by selecting one of a normal flashlight and a flashlight that is effective for alleviating a red-eye phenomenon and that contains less red light than normal flashlight does;
- an information recording means for recording photographic information on a film, and
- a recording control means for allowing said information recording means to record a flashlight selected by said switching means.

A camera having a strobe unit, comprising:
- a strobe flashing means for emitting illumination light toward an object;
- a strobe flashlight changing means for changing a spectrum of visible light emitted by said strobe flashing means for purpose of red-eye reduction;
- a magnetic recording means for recording given photographic information in a magnetic recording medium on a film;
- a strobe flashlight checking means for check that strobe flashlight emanating from said strobe flashing means has been changed by said strobe flashlight changing means;
- and
- a recording control means that, when said strobe flashing means flashes, causes said magnetic recording means to record on said magnetic recording medium information concerning correction of a print of an image associated with said information according to a result of checking made by said strobe flashlight checking means to compensate for a change in a spectrum of visible light.

A camera having a strobe unit, comprising:
- a light source for emitting illumination light toward an object;
- a flashlight spectrum changing means for selectively reducing red light in a visible range contained in illumination light emanating from said light source for preventing red-eye phenomenon;
- a red-eye phenomenon determining means for determining whether an image to be photographed is prone to a red-eye phenomenon;
- and
- a control means that when said red-eye phenomenon determining means determines that a red-eye phenomenon may occur, activates said flashlight spectrum changing means.
2 more elements
A strobe unit, comprising:
- a plurality of light sources for emitting flashlights said sources having different spectra;
- a red-eye phenomenon determining means for determining whether an image to be photographed is prone to a red-eye phenomenon;
- and
- a flashlight control means that when said red-eye phenomenon determining means determines that a red-eye phenomenon will not occur, allows said plurality of light sources to flash at a given ratio of amounts of light so that a combination of the spectra of light emanating from said plurality of light sources resemble a spectrum of sunlight, and that when said red-eye phenomenon determining means determines that a red-eye phenomenon may occur, controls flashing of said plurality of light sources so that flashlight emanating from said plurality of light sources will contain less red light than a flashlight emitted at said given ratio of amounts of light.
