Problems solved by technology
The first method requires a larger space, and the cost is also higher; the second method is barely suitable for general speeches, but for the performers on the stage, it limits the performance of the performers
Therefore, both methods have certain limitations.

Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0020] The present invention provides a projector designed to avoid projecting an image on a person's face or body. In order to achieve the above purpose, refer to figure 1 and figure 2 , the projector of the present invention includes a lens 10 , an image processing device 30 and an image projection device 50 . Wherein, the lens 10 is used for capturing a face image or a face and body contour, for example, capturing a face image or a face and body contour of a presenter or a performer standing on a stage. The lens 10 is connected to the image processing device 30 , and transmits the captured face image or face and body outline to the image processing device 30 . Preferably, the lens 10 can be a laptop lens, which is beneficial to control the cost of the projector while saving spac...

The invention provides a projector and a method for avoiding projecting a projected image on a human body. The projector comprises a lens, an image processing device and an image projection device, wherein the lens is used for capturing a facial image or a face and body contour; the processing device is connected to the lens for receiving the facial image or the face and body contour from the lens, and processing an area corresponding to the facial image or the face and body contour in a to-be-projected image without displaying the image in the area; and the image projection device is connected to the image processing device for projecting the image processed by the image processing device. According to the projector and the method for avoiding projecting the projected image on the human body, a problem of projecting the image on the face or the body is effectively solved, the embarrassment caused by projecting the image on the face or the body is avoided, and the stimulation of the projected light to eyes is eliminated.
Description
technical field [0001] The invention relates to the technical field of projectors, in particular to a projector and a method for preventing projected images from being projected on a human body. Background technique [0002] Nowadays, projectors are often used in occasions such as evening parties, awards ceremonies, and various conferences. The projectors project images on walls or curtains as the background of the stage or as assistant speakers for speeches. However, it often happens that the image projected by the projector is irradiated on the face or body, which not only affects the image of the person being irradiated, but also the light projected by the projector will stimulate the eyes of the person being irradiated, affecting the image of the person being irradiated. line of sight. [0003] In order to avoid the above-mentioned phenomenon, there are mainly two solutions currently adopted, one is to use a rear projection device instead of a projector, and the other i...
