Ａ、産業上の利用分野
本発明は、閃光撮影時の赤目現象を防止するカメラの赤
目防止制御装置に関する。DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a red-eye prevention control device for a camera that prevents red-eye phenomenon during flash photography.
Ｂ、従来の技術
赤目現象とは、電子閃光装置を用いたカラー写真撮影に

毛細血管が多数存在し、その血液中のヘモグロビンが赤
色であるので、その反射光が赤みを帯びて写るのである
。B. Prior Art The red-eye phenomenon refers to a phenomenon in which human eyes appear to glow red or gold when photographing in color using an electronic flash device. This phenomenon occurs when the flash of light from the light emitting part of an electronic flash device passes through the pupil of the eye and is reflected by the retina, and the reflected light is reflected by the fino? It is also a male that appears in the picture. There are many capillaries in the retina of the eye, and the hemoglobin in the blood is red, so the reflected light appears reddish.
赤目現象が写真で顕著に現れるのは、以下のような条件
下であることが経験的に判明している。It has been empirically determined that the red-eye phenomenon appears conspicuously in photographs under the following conditions.
１）撮影環境が暗い場合
人間の眼の瞳孔の大きさは周囲の明るさによっ° て変
化し、暗い場合にはその直径が約７〜８＋１１１１に拡
がっている。このときは眼への入射光量および反射光量
は多くなるので、当然赤目現象も目立ちやすい。1) When the photographing environment is dark The size of the pupil of the human eye changes depending on the surrounding brightness, and when it is dark, the diameter expands to about 7 to 8 + 1111. At this time, since the amount of light incident on the eye and the amount of reflected light increase, the red-eye phenomenon is naturally more noticeable.
２）電子閃光装置の発光部と撮影レンズ光軸との距離が
近い場合
眼の網膜部分はかなりの高反射率であると同時に、また
反射の指向性も高い。従って電子閃光装置の発光部と撮
影レンズ光軸とが近く、網膜による正反射光がそのまま
撮影レンズに入射しやすい位置関係に３つの要素（発光
部、撮影レンズ、眼）がある場合は、赤目は強く発生す

閃光光源の発光部とを見込む角度が、ある程度以下の小
さい角度以下になっているときには、赤目は必ず発生す

て、電子閃光装置の発光部を撮影レンズ光軸から離せは
赤目の発生が防止されるが、カメラから被写体までの距
離（以下、被写体距離と呼ぶ）により限界があり、被写
体距離が所定値以上では赤目を避けることは困難である
。2) When the distance between the light emitting part of the electronic flash device and the optical axis of the photographing lens is short, the retina of the eye has a fairly high reflectance and also has high reflection directionality. Therefore, if the light emitting part of the electronic flash device and the optical axis of the photographing lens are close to each other, and there are three elements (light emitting part, photographing lens, and eye) in a positional relationship where the light regularly reflected by the retina easily enters the photographing lens, red-eye occurs strongly. That is, when the angle at which the photographic lens and the light emitting part of the flash light source are viewed by the eyes of the person who is the subject is less than a certain small angle, red eye always occurs. Empirically, this angle is approximately 2-2.5 degrees. Therefore, red-eye can be prevented by moving the light emitting part of the electronic flash device away from the optical axis of the photographic lens, but there is a limit depending on the distance from the camera to the subject (hereinafter referred to as subject distance), and the subject distance is greater than a predetermined value. It is difficult to avoid red eyes.

The July 1952 issue discloses a method to prevent red-eye by allowing your eyes to get used to a bright environment before taking a photo, and then firing the flash while your pupils are reduced to 3 mm or less. Also,
Japanese Patent Publication No. 58-4.8088 discloses that pre-irradiation is performed using a pre-irradiation lamp before photographing for the time required for the pupil to close and move, and when the pupil has reached almost its minimum diameter, an electronic flash device is used. A technique has been disclosed for photographing by emitting light from the light emitting part of the camera. Furthermore, in Japanese Patent Publication No. 58-9130, two flash discharge tubes are provided, and after the -power discharge tube emits a pre-emission to close the pupil, the second discharge tube emits the main light and the actual light is emitted. A method for photographing is disclosed.

写真が撮影されてしまう。C0 Problems to be Solved by the Invention However, with this type of device, if the subject does not look at the camera during the pre-irradiation but looks at the camera during the main flash, the pupil may shrink even after the pre-irradiation. I can't do it,
Red eye is not prevented. Additionally, since the flash is fired twice, the pre-irradiation and the main flash, there is a risk that the subject may mistakenly think that the shooting has finished during the pre-irradiation and turn to the side or close their eyes. When photography is performed, an undesirable photograph is taken.

If the temperature is below this level, red eyes will occur more frequently. Now, taking lens R
When the distance between the optical axes of E and the xenon tube Xel is H, the angle is expressed as ta mouth θ = H/D, and from this formula, the subject distance is D = H/1a
It can be expressed as nO(1). Therefore, for example, if the distance H between the optical axes of the photographing lens RE and the xenon tube Xel of the electronic flash device 10 is 0.1 m, and it is specified that red eye will occur when o = 2 degrees or less, red eye will occur due to the distance to the subject. It can be considered that this occurs at approximately D=28.6XO, lm=2.86m or more. therefore,(
The subject distance determined by formula 1) can be used as a reference value for determining the photographing conditions under which red eye occurs.

赤目が発生すると言うことができる。On the other hand, when the subject brightness B is so high that it exceeds a predetermined standard, the pupils are closed, so the red-eye phenomenon hardly occurs. In other words, it can be said that red eye occurs when the subject's lateral power is less than a predetermined reference value at which the human pupil becomes large enough to cause red eye.

If these conditions are satisfied in step S12, the process proceeds to step 813; if not, the process proceeds to step 81.
．． Proceed to step 4. In step S13, the red-eye prevention mode is set, and then the process returns to step S2, and the processes from step 82 onwards are repeated. Note that the above-mentioned distance H is calculated within the CPU 1 by inputting a signal corresponding to the height position of the cannon tube Xel from the electronic flash device 10 side to the camera side, for example.

Furthermore, although an example has been shown in which the electronic flash device is automatically activated when the subject is dark, the main flash may be performed manually in conjunction with the release operation. Furthermore, the camera side automatically determines red eye detection based on the subject distance and subject brightness B, and pre-irradiation is performed by pressing the release button all the way down, but only a warning is given, and whether or not to perform pre-irradiation is determined separately. The photographer may select one using a switch. Alternatively, the camera may not make any determination as to whether red-eye has occurred, and the photographer may operate an operation switch after determining that the photographing conditions are such that red-eye has occurred, and when a release operation is performed at this time, pre-irradiation may be performed.
