Embodiment Construction

[0026] In order to solve the problem in the prior art that the reporter cannot operate the mouse and the laser pointer at the same time. The invention proposes a conversion processing system capable of converting a cursor on a projection screen into a cursor. figure 1 It is a schematic diagram of the structure of the present invention. The processing system for converting a cursor on a projection screen into a cursor of the present invention includes an optical pointer device 110 , a computer 120 , a projection device 130 and an image capture device 140 .

[0027] The optical indicator device 110 may be but not limited to a laser pointer (laser pointer), or a light-emitting diode (Light-Emitting Diode, referred to as LED) light-emitting device that can produce a clear cursor 153 on the projection surface. within the scope of protection of the invention. Wherein, the cursor described in the present invention is a light spot (spot) when the optical indicator device projects li...

Abstract

The invention discloses a conversion processing method and system for converting cursors on a projection image into verniers. The conversion processing method includes the following steps that a projection device is driven to generate a projection image; an image capturing device is connected to a computer, and the projection image shot by the image capturing device is transmitted to the computer; cursors are projected by an optical indicatrix device in the projection image; the range of an operation image area is recognized by the computer according to the projection image; the corresponding relation between the operation image area and a displaying area of the computer is calculated, locations of the cursors are found out by the computer according to the difference between first brightness of the operation image area and second brightness of the cursors, and the movement corresponding amount of the cursors is calculated through the corresponding relation; the verniers in the displaying area are moved to corresponding locations by the computer according to the locations of the cursors corresponding to the displaying area.

Description

technical field [0001] The present invention relates to a conversion processing method and system for converting a cursor on a projection screen into a cursor, and particularly relates to a conversion processing method and system for converting a cursor on a projection screen into a cursor. Background technique [0002] In the past, the existing reporting method was for the reporter to speak to the masses through different projection films. The reporter should also change the projection film at the same time as the speech, so that the audience can watch the reported content synchronously. [0003] With the advancement of science and technology, the types of reporting methods have also undergone many changes. However, most of the current reporting methods use computers and projectors as tools for the reporter to play the content of his report. Because the reporter needs to pay attention to the content of his speech in the process of reporting, and switch the slides during t...
