Claims (1)

[Claims for Utility Model Registration] (1) A flash device that emits a flash of light at a subject, a red-eye prevention means that emits a first red-eye prevention light that shrinks the human pupil toward the subject, and a camera or the flash device. A display light for notifying the state and a second red-eye prevention light having a brightness higher than the display light and lower than the first red-eye prevention light in order to shrink the human pupil are directed toward the subject, respectively. a light emitting means capable of emitting light; and a red eye determination means for determining a red eye occurrence condition and outputting a red eye determination signal when the brightness information indicates that the pupil has become large enough to cause a red eye phenomenon. , a distance measuring means that outputs a long-distance signal when it detects that the distance to the subject is equal to or greater than a predetermined distance; The control means includes a control means for irradiating at least one of the prevention lights toward the subject, and the control means controls the control means to emit light from the flash device when both the red-eye determination signal and the long-distance signal are output. The first red-eye prevention light is emitted toward the subject, and when the red-eye determination signal is output but the long-distance signal is not output, the first red-eye prevention light is prohibited from emitting light, and the flash device is configured to emit light. A red-eye prevention control device for a camera, characterized in that the red-eye prevention means and the light emitting means are controlled to first emit the second red-eye prevention light toward a subject. (2) The control means causes the light emitting means to generate the display light when the flash device completes charging for flash light emission, and when the display light is not emitted even if the red eye determination signal is output, the control means causes the display light to be emitted from the light emitting means. 2. The red-eye prevention control device for a camera according to claim 1, characterized in that it does not generate red-eye prevention light.
