Abstract
The invention discloses an autofocus projector which comprises a frame, a light source, a lens (1) and the like. A test lens (3) and a focusing test circuit (4) are arranged on the front end of the projector (2). A lens adjusting device (5) is arranged. When the projector is used, the test lens (3) acquires a projection image of the projector on a screen. The focusing test circuit (4) carries out corresponding definition detection. A lens adjustment device (5) carries out corresponding lens (1) focal adjustment. After repeated test, the projector acquires a best projection effect. A prompt module (6) is arranged. When automatic focusing is completed, corresponding prompt information is issued. The shape structure of the test lens (3) is in a pinhole structure. The diameter of the lens is less than 1cm. Automatic focusing of the projector is realized, so that the use of a user is convenient, and the work efficiency is improved.
Description
Technical field
The present invention relates to a kind of projector.
Background technology
Projector in existing work is common office appliance, and it generally needs manual focus, very trouble while use.
Summary of the invention
Object of the present invention is just to provide a kind of projector that can automatically realize focusing.
The present invention realizes like this.Automatically the projector of focusing, comprise frame, light source, camera lens etc., at the front end of projector, testing lens and focusing test circuit are set, lens adjusting apparatus is set, when use, testing lens obtains the projection image of projector on screen, focusing test circuit carries out corresponding sharpness detection, and lens adjusting apparatus carries out corresponding lens focus adjustment, thereby test makes projector obtain best projection effect repeatedly.
Automatically the projector of focusing, arranges reminding module, can send corresponding information when automatic focusing completes.
Automatically the projector of focusing, the mode of prompting can be that auditory tone cues or LED light show.
Automatically the projector of focusing, arranges automatically to focal switch, to control enabling of automatic focusing function.
Automatically the projector of focusing, the outer pin structure of contour structures of testing lens, diameter of lens is less than 1 centimetre.
The projector of above-mentioned automatic focusing, can realize the automatic focusing of projector, and person easy to use uses, and increases work efficiency.
Accompanying drawing explanation
Accompanying drawing is the structural representation of the projector of automatic focusing.
Number in the figure is respectively: 1-camera lens, 2-projector, 3-testing lens, 4-focusing test circuit, 5-lens adjusting apparatus, 6-reminding module, 7-are automatically to focal switch.
