Embodiment Construction

[0015] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] see figure 1 , which is the projection screen operating system 100 according to the embodiment of the present invention. The projected image operating system 100 includes a cursor unit 10 , an image sensing unit 20 and a control unit 40 . The image sensing unit 20 is electrically connected to the control unit 40 .

[0017] The cursor unit 10 generates red light with a certain frequency and projects it onto the projection screen to form a cursor. cursor. The cursor unit 10 is separately arranged outside the projector for remote control operation, such as a light pen.

[0018] The image sensing unit 20 senses the projected image and the cursor and forms corresponding images. The image sensing unit 20 includes an image sensor capable of sensing ambient light and imaging, such as a Charge-Coupled Device (CCD), a Complementary Metal ...

Abstract

The invention discloses a projection picture operation system which comprises a cursor unit used for forming a cursor with a characteristic token state on the projection picture; an image sensing unitused for sensing the projection picture and the cursor and forming a corresponding image; and a control unit used for confirming the position of the projection picture in the image and the position of the cursor in the projection picture. An operation area and the central point of the operation area are confirmed according to the position relation between the cursor and the projection picture; and the characteristic token state of the cursor is obtained and corresponding operations are carried out on the operation area by taking the central point of the operation area as a central point and by selecting the corresponding operation mode according to the characteristic token state. The projection picture operation system is simple and quick to be operated, and leads the user of the projection picture to be capable of more conveniently carrying out operation on the projection picture. The invention also provides an operation method for the projection picture.

Description

technical field [0001] The invention relates to an operating system, in particular to an operating system and an operating method for a projection screen of a projector. Background technique [0002] At present, during the use of the projector, it is necessary to perform operations on the projected picture, such as reducing, enlarging or moving the projected picture. Generally, it is necessary to use a computer to complete the picture operation on the projected picture. [0003] However, this method of operating the screen cannot be operated away from the computer. Therefore, when the user is far away from the computer and directly explains next to the projection screen, the corresponding operation cannot be performed on the projection screen immediately, which is inconvenient to operate and cannot meet the needs of the user. Contents of the invention [0004] In view of this, it is necessary to provide a projection screen operating system and operation method that can co...
