Description
Technical field
The present invention is about a kind of indicating device that is used for an optical projection system.In more detail, the present invention is in the optical projection system, and the luminous energy of convertible projected picture is as power supply, and wireless transmission capable of using and the device of initiatively projected picture being indicated.
Background technology
When using the projection equipment, indicating device on the market has various different appearance and function, and modal a kind of indicating device is a laser pen, and it can produce luminous point and indicate emphasis at any time, is indispensable instrument indispensable in the bulletin.
Each function of traditional laser pen is more and more perfect after several times improveing; Except the most basic luminous point indication; The laser pen of a new generation has still added the easy control function of part, and for example remote-controlled computer carries out transparency and skips, and bulletin can not interrupted because of the needs operating computer in carrying out.Yet the laser pen major function is still and on projected picture, produces the indication luminous point, so comparatively power consumption often runs into the puzzlement that needs to change battery in the use, if adopt jumbo battery to cause the volume of laser pen excessive again easily.
In addition; Present presentation software is quite ripe, for example, in bulletin carries out, points out if will make emphasis; The user understands the mouse of direct control computer usually; Switch in the presentation software to the paintbrush function, or utilize computer graphics special-purpose ruling pen and plotting sheet, directly paintings emphasis mark is write or enclosed to this bulletin file.This kind mode has following shortcoming; Can't directly go to carry out because bulletin is underway with laser pen; Must just switch to the paintbrush pattern through computation, or must just be able to draw, the bulletin process is interrupted through other computer graphics instruments; And must itself edit the bulletin file on using; Switch to the paintbrush pattern and with mouse during as instrument, scope of its circle picture is produced by random towing especially, can't with the emphasis part in addition carefully and neatly sign reach and effectively be presented on the projected picture.
Summary of the invention
A purpose of the present invention; Be to provide a kind of indicating device that is used for optical projection system, because the projected picture that optical projection system is throwed has sufficient luminous energy, and indicating device of the present invention is provided with photoelectric conversion device; Can be electric energy with this luminous energy local transitions just, confession itself be used.Thus, indicating device of the present invention can solve the problem of replacement battery.
Another object of the present invention is that this indicating device can initiatively launch a signal, pick out the position of indicating device with respect to projected picture in order to optical projection system, and optical projection system can be noted down the position of indicating device, and immediately be shown in projected picture.Thus, for example, carry out the signs such as symbol, emphasis line, frame choosing of directly projected picture being annotated in the process at bulletin, the user need not operating computer equipment, makes the bulletin process more coherent smooth and easy.Can infer ground, this kind mode is not only easy and simple to handle, and the mark that is increased is unlikely mixed and disorderly, more presses close to the mode that user institute desire is expressed.
For reaching aforementioned purpose, the present invention provides a kind of indicating device that is used for an optical projection system, and indicating device comprises a body, a transmitting device and a photoelectric conversion device.Wherein transmitting device is arranged in the body and in order to launch a signal; Photoelectric conversion device is arranged on the body and in order to the luminous energy that will be projeced into a projected picture and partly converts an electric energy into, to provide to this transmitting device use.
After consulting embodiment graphic and that describe subsequently, affiliated technical field has common knowledge the knowledgeable and just can understand other purpose of the present invention, advantage and technological means of the present invention and implement aspect.
