4. 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.

6. 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. - View Dependent Claims (7, 8, 9)

10. 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.
