摘要： Method and systems for autofocus triggering focusing are disclosed herein. In one example, a system may include a lens, a memory component configured to store lens parameters of the lens and regions of focus corresponding to the lens parameters, and a processor coupled to the memory and the lens. The processor may be configured to focus the lens on a target object at a first instance of time, receive information indicative of distances from an imaging device to the target object over a period of time, obtain lens parameters of the lens, and determine a region of focus, and trigger the lens to re-focus on the target object if the distance to the target object indicates the target object is outside of the region of focus and the distance to the target object is unchanged for a designated time period.

摘要： There is disclosed a microfilm reader-printer which permits to be set a number of pages of printing which exceeds a maximum number of pages of continuous printings of the printer body. The printer body outputs a completion signal to a device which set the number of pages of printing when printing is completed. The device sends a print request signal to the printer body every time when it receives a complete signal, until completion of printing for the set number of pages. The printer body completes the printing operation once for each maximum continuous number of pages of printing, but resumes printing if a print request signal is outputted successively.

摘要： In the disclosed finder, an auxiliary lens for changing the magnification power is inserted into the space between an objective lens and an eyepiece. The size of the viewfield frame is simultaneously changed to maintain a constant percentage of the viewfield of the finder. The required rate of change of magnification power that the auxiliary lens must attain to leave the size of the viewfield frame of the finder unchanged can be reduced with the advantage of minimizing the bulk and size of the finder.

摘要： The present invention is directed to a reader printer which handles an image of a microfilm held by an aperture card and maintained in such a manner that the microfilm center aligns with the center of card aperture. At the time of printing, the image of the microfilm is projected by scanning from a scanning start position that is same irrespective of film sizes on a photosensitive member, and the image thereon is transferred to a paper sheet which is provided by cutting the web supplied from rolled paper. The supply of the web is controlled by a first timer which starts simultaneously with start of scanning and the cutting of the web is controlled by a second timer which starts simultaneously with expiration of the first timer.

摘要： In the disclosed finder, a half transparent surface positioned behind a photographic lens splits off part of the light passing through the photographic lens to a first image plane at a position equivalent to a focal plane of the photographic lens. At least two lens components refocus light from the first image plane onto a second image plane conjugate to the first one. An image on the second plane is observed through an eyepiece. An even number of reflective surfaces, but not less than four, including the half transparent surface, are arranged in an optical path from the photographic lens to the eyepiece and at least one of these reflective surfaces lies between the two lens components. A decrease in the physical length of the finder and an increase in the image magnification are achieved.

摘要： A Kepler telescope type optical finder system for an SLR camera comprises a simple and compact prism having a generally wedge shape as contrasted with finder optical systems using surface mirrors or pentaprisms. The prism may be shaped so that the angle formed by the incident optical axis thereto and the emitting optical axis therefrom is smaller than 90.degree. in order to further miniaturize the overall size of the camera. In this case, an additional wedge-shaped prism is inserted between the first focal plane of the optical system and the prism in order to reduce the chromatic aberration. The additional wedge-shaped prism may be provided with a surface formed into the surface of the condenser lens.
