Abstract
A device suppresses blur by light refraction in a photographically formed image, thereby stabilizing the image. The device includes a detector for detecting whether a conversion lens for varying the focal length of the photographic lens is attached in front of the device or not, or a setting device for setting the presence or absence of such a conversion lens, the amount of light refraction being varied in accordance with the output of the detector or the setting device.
Claims13
A photographic system for stabilizing a photographically formed image, comprising:
- a photographic lens means for forming said image;
- a light refraction means for causing light refraction in order to stabilize the image;
- a conversion lens means for converting the focal length of said photographic lens means;
- and
- a means for varying the light refraction amount of said light refraction means in accordance with whether said conversion lens means is attached.
An image stabilizing device which is provided between a photographic lens and a conversion lens means for converting the focal length of said photographic lens and which is adapted to stabilize images formed by said photographic lens, comprising:
- a light refraction means for causing light refraction;
- and
- a means for varying the light refraction amount of said light refraction means in accordance with whether said conversion lens means is attached.
An image stabilizing system comprising:
- an objective lens means;
- a variable-apex-angle prism means for stabilizing an image, which is arranged at the rear of said objective lens means to refract light;
- and
- means for varying a light deflection angle of said variable-apex-angle prism means in accordance with the optical characteristics of said objective lens means.
