Description

用于一投影系统的指示装置 Means for instructing a projection system

技术领域 FIELD

[0001] 本发明关于一种用于一投影系统的指示装置。 [0001] The present invention relates to a projection system for a pointing device. 更详细地说,本发明为投影系统中,可转换投影画面的光能作为电源,并且可利用无线传输而主动对投影画面进行指示的装置。 More particularly, the present invention is a projection system, the projection screen can convert light energy as a power source, and may be an indication of a active picture projection using radio transmission.

背景技术 Background technique

[0002] 在使用投影器材时,市面上的指示装置有各种不同造形及功能,最常见的一种指示装置是激光笔,其可产生光点随时指示重点,是简报中不可或缺的必备工具。 [0002] When using projection equipment, indicating means on the market there are various Zaoxing and functions, the most common device is a laser pointer for indicating that the light spot may be generated at any time direct the focus, it must be integral presentation Preparation tool.

[0003] 传统的激光笔各部功能在几经改良后愈来愈完善,除了最基本的光点指不之外, 新一代的激光笔尚附加了部分简易的控制功能,例如可遥控电脑进行投影片换页,让简报进行中不会因需要操作电脑而受打断。 [0003] The conventional laser pointer function of each part after much improved more and more perfect, but the most rudimentary means not outside the spot, the new generation of laser pen still some simple additional control features such as remote computers Powerpoint feed, make presentations in progress will not need to operate computers but by the break. 然而,激光笔主要功能仍是在投影画面上产生指示光点,故较为耗电,使用上经常遇到需要更换电池的困扰,若采用大容量的电池又容易造成激光笔的体积过大。 However, the main function of the laser pen is still generated in the light spot on the projection screen indication, it consumes more power, problems often encountered need to replace the use of battery, the use of a large-capacity battery and easy to create excessive volume of the laser pointer.

[0004] 此外,目前的简报软件已相当成熟,譬如,在简报进行中若要作重点提示,使用者通常会直接操作电脑的鼠标,来切换简报软件中的到画笔功能,或利用电脑绘图专用的绘图笔及绘图板,直接对该简报文件进行书写或圈画作重点标注。 [0004] Further, the present presentation software is quite mature, for example, in a presentation for the MLA to prompt the user usually directly operate a computer mouse, to switch the function to brush presentation software, or the use of special computer graphics the pen and graphics tablet, to write or direct the focus ring paintings marked the briefing document. 此种方式存有如下缺点,因为简报在进行中无法直接以激光笔去执行,必须通过电脑操作才可切换到画笔模式,或是必须通过其他电脑绘图工具才得以绘制,如此会使简报过程受到打断,且使用上必须对简报文件本身进行编辑,切换到画笔模式且以鼠标作为工具时,其圈画的范围更是由随意拖曳所产生,无法将重点部份加以工整标示及有效呈现于投影画面上。 In this way there the disadvantage, since during the presentation can not be executed directly to the laser pointer, the computer must be switched by the operation mode is available to the pen, or be able to draw it by other computer drawing tools, so the process will be presentations interrupted, and the use of the file must be edited for presentation itself, to switch to the brush mode and when the mouse as a tool mark your range is generated by the random drag, can not be neatly labeled and focus most effectively presented projected on the screen.

发明内容 SUMMARY

[0005] 本发明的一目的,在于提供一种用于投影系统的指示装置,由于投影系统所投射的投影画面具有充足的光能,而本发明的指示装置上设有光电转换装置,恰可将该光能局部转换为电能,供本身使用。 [0005] The object of the present invention is to provide a pointing device for a projection system, the projection system due to the projected projection have sufficient energy, and is provided with a photoelectric conversion device of the present invention, the pointing device, may be appropriate the local energy is converted into electrical energy for their own use. 如此一来,本发明的指示装置可解决替换电池的问题。 In this way, the pointing device of the present invention can solve the problem battery replacement.

[0006] 本发明的另一目的,在于该指示装置可主动发射一信号,以利投影系统辨识出指示装置相对于投影画面的位置,而投影系统可纪录指示装置的位置,并即时地显示于投影画面。 [0006] Another object of the present invention, in that the indication means may actively transmit a signal, in order to facilitate the projection system identified pointing device position with respect to the projection screen, the projection system may record the position of the pointing device, and displayed in real time projection screen. 如此一来,例如,在简报进行过程中直接对投影画面进行加注符号、重点划线、框选等标示,使用者无须操作电脑设备,让简报过程更为连贯顺畅。 Thus, for example, on the projection screen in the briefing carried out directly during filling symbol, focusing on marking, labeling and other marquee, users do not operate computer equipment, make presentations more coherent process smoother. 可想见地,此种方式不但操作简便,且所增加的标记不至杂乱,更贴近使用者所欲表达的方式。 Can be conceivable, such a simple embodiment only, and not to mark the increased clutter, closer to the desired mode of expression of the user.

[0007] 为达成前述目的,本发明提供一种用于一投影系统的指示装置,指示装置包含一本体、一传输装置以及一光电转换装置。 [0007] To achieve the above object, the present invention provides an apparatus for indicating a projection system for the indicating device comprises a body, a transmitting device and a photoelectric conversion device. 其中传输装置设置于本体内并用以发射一信号;光电转换装置设置于本体上并用以将投射于一投影画面的光能部分转换为一电能,以提供至该传输装置使用。 Wherein the transmission means provided in the main body and configured to emit a signal; a photoelectric conversion means disposed on the body and configured to project light energy in a portion of the projected image is converted into an electrical energy, to provide to the device using the transmission.
