Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further elaborated.
Be illustrated in figure 1 the syndeton schematic diagram of fixed-focus system of the present invention, a kind of projector equipment fixed-focus system, comprise the electromotion focusing unit for regulating projection lens focal length, focus control module, described electromotion focusing unit comprises the focusing component for moving lens, for driving the focusing CD-ROM drive motor of described focusing component; The described control module that focuses comprises and focuses control processor and focus Trackpad, described in focus Trackpad and focus control processor and be electrically connected, focus control processor and be electrically connected with focusing CD-ROM drive motor.
If Fig. 2 is fixed-focus system of the present invention assembling schematic diagram; Described focusing component comprises focusing wheel 1, focusing lever 2 and the stop means 3 for limiting lens moving stroke, drives focusing lever to move by the rotation of drive motor focusing wheel, realizes further controlling the mobile of camera lens by the movement of focusing lever.
Be illustrated in figure 3 electromotion focusing cellular construction schematic diagram of the present invention, described CD-ROM drive motor 4 drive focusing wheel 1 along clockwise direction or counterclockwise transmission drive focusing lever to move up and down, realize moving forward and backward camera lens further by the mobile of focusing wheel, thus realize the adjustment of lens focus; As the embodiment that is enumerated, when wheel clockwise direction of focusing is rotated, drive focusing lever to move downward, thus camera lens is moved backward; Otherwise, when wheel of focusing counterclockwise rotates, then drive focusing lever to move upward, thus camera lens moved forward.
A kind of projector focuses method, comprises the following steps:
(1) open projector equipment, electromotion focusing unit moves focusing to camera lens automatically in focusing stroke range;
(2) when electromotion focusing unit projected picture is transferred to the most clearly position time, focus Trackpad by striking and realize focusing.
Further, the focusing stroke of described electromotion focusing unit is focused control processor and is controlled.
Be illustrated in figure 4 the embodiment of the present invention and focus method schematic diagram; Described step determines that the step of the most clear projected picture comprises in (2), when electromotion focusing unit moving lens is to during shortly past the most clear projected picture position, manual striking focuses Trackpad, focusing control processor is first focus position by this position mark, subsequently, electromotion focusing unit drives camera lens to focus between position and initial focusing position mobile focusing first, thus reduces the scope of focusing stroke, improves the degree of accuracy that focuses and focuses efficiency.
If Fig. 5 is that the present invention repeatedly focuses method schematic diagram, focuses step and also comprise in described step (2), when projected picture is adjusted to pre-clear position by electromotion focusing unit, striking focuses Trackpad, focuses control processor and is recorded as first and focuses position, electromotion focusing unit continues moving lens position and focuses, and when being transferred to projected picture the most clearly, when projected picture starts to fog, striking focuses Trackpad again, focuses control processor and this position is recorded as second focuses position, subsequently, camera lens is focused position and first second and focuses between position and move back and forth focusing by electromotion focusing unit, when projected picture is transferred to the most clear, striking focuses Trackpad, determine pinpointed focus, as further preferred version, also can focus in focusing stroke that position and second focuses position first and reduce focusing stroke further, such as, focus position at camera lens from second to return first and focus the process of position, determine that the 3rd focuses position and the 4th and focus position, thus focusing of the best is locked in the 3rd and focuses position and the 4th and focus between position, reduce further and focus stroke range, improve the degree of accuracy that focuses and focus efficiency.
Further, stroke range is focused above by what constantly reduce electromotion focusing unit, repeatedly focus and determine in the process of pinpointed focus afterwards, often reduce stroke range of once focusing, the speed of electromotion focusing unit moving lens is slack-off, and namely focal length variations slows down, such as, before zoom speed is reduced to 1/2nd, be conducive to operator like this and determine best projected picture position more easily, thus realize focusing more accurately.
Based on a projector equipment telepilot matching method for above-mentioned fixed-focus system, comprise the following steps:
