Abstract
A projection system, including the ray apparatus camera lens of treater, transmission image, receive and present the projection curtain of image and the focusing module of focusing, projection system still includes the distance sensor of distance between sensing projection curtain and the ray apparatus camera lens and the motor of being connected with the module of focusing, motor and distance sensor all with treater electric connection. Projection system, adopt the motor to carry out automatic focusing, avoided the loaded down with trivial details process of manual focusing, save time to work efficiency is greatly improved.
Description
Technical field
This utility model relates to a kind of optical projection system, particularly relates to the optical projection system of a kind of automatic focusing.
Background technology
Projector is the important tool that people carry out demonstrating at work, being typically necessary manual focusing before use, so that projector can clear, ideally show speech content, but this process is relatively complicated, and owing to the precision of projector is higher, manually regulation is readily adjusted and excessively loses time.
Utility model content
This utility model is i.e. to overcome prior art not enough, it is provided that can the optical projection system of automatic focusing.
Specifically, a kind of optical projection system described in the utility model, the ray machine camera lens of including processor, launching image, receive and present the projection screen of image and the focusing module focused, described optical projection system also includes sensing projection screen and the range sensor of the spacing of ray machine camera lens and the motor being connected with focusing module, described motor and range sensor all with processor electric connection.
Further, described projection screen is curtain or wall.
Further, described motor is motor.
Further, described range sensor and the spacing of projection screen are equal to ray machine camera lens and the initial separation of projection screen.
Optical projection system described in the utility model, uses motor to carry out automatic focusing, it is to avoid the complicated processes of manual focusing, saves the time, thus substantially increase work efficiency.
Accompanying drawing explanation
Fig. 1 is the three-dimensional exploded view of this utility model optical projection system；
Wherein, 100 is optical projection system, and 1 is processor, and 2 is ray machine camera lens, and 3 is projection screen, and 4 is range sensor, and 5 is motor, and 6 is focusing module.
Detailed description of the invention
Below in conjunction with accompanying drawing, optical projection system described in the utility model is illustrated without limitation in order to the public is more fully understood that described technology contents.
As it is shown in figure 1, optical projection system 100 described in the utility model, it is mainly used in computer or other intelligent terminal, it is achieved the display of lecture content.Described optical projection system 100 includes processor 1, the ray machine camera lens 2 launching image, receives and present the projection screen 3 of image and the focusing module 6 focused, described processor 1 is connected with intelligent terminal by the outside port of optical projection system, and receive its video signal, and launch image by ray machine camera lens 2, finally present on projection screen 3.Described projection screen 3 can be the wall of curtain or light color.
Described optical projection system 100 also includes sensing projection screen 3 and the range sensor 4 of spacing L of ray machine camera lens 2 and the motor 5 being connected with focusing module, and described motor 5 and range sensor 4 are all electrically connected with processor 1.Specifically, range sensor 4 senses the light that projection screen 3 reflects, thus draw the distance between ray machine camera lens 2 and projection screen 3, in the present embodiment, described range sensor 4 can immediately arrive at distance L equal to ray machine camera lens 2 and the initial separation of projection screen 3, such range information without converting with the spacing of projection screen 3.Described motor 5 is motor, and described processor 1 sets the number of times of the stepping of motor according to distance L drawn.When such as distance is 3 meters, stepping number of times is set to 4 steps.The L that i.e. adjusts the distance sets up relation one to one with motor stepping number of times, thus realizes automatic focusing.And set up these corresponding relations, then performed by processor, known technology should be belonging to, do not repeat them here.
It should be understood that; foregoing is not the restriction to described technical scheme; in fact; all improvement described technical scheme carried out with identical or approximation principle; including the shape of each several part, size, the improvement of material used; and the replacement of identity function element, all within the technical scheme that this utility model is claimed.
Claims (4)
