Projector output mode switching method and system

Abstract

The invention discloses a projector output mode switching method and system. The method comprises the steps that a camera photographs a projection area, a photographed first image is evenly divided into N areas, statistics of the brightness values of the N areas is respectively performed, and whether the projection area has ambient light and the ambient light type are determined according to the brightness values; a projector projects a template image to a currently used screen, the camera arranged on the projector photographs the projection area and then obtains a second image and stores, first cumulative brightness of the left half part of the second image and second cumulative brightness of the right half part of the second image are acquired, and the type of the screen is determined according to the first cumulative brightness and the second cumulative brightness; and a corresponding output mode is selected for output according to the type of the currently used screen and existence of ambient light. The type of the current projection screen can be identified firstly, and the output model of the projector is automatically adjusted according to the type of the screen so that the best display effect can be realized on any screen.

Description

technical field [0001] The present invention relates to the field of projection technology, in particular to a method and system for switching an output mode of a projector. Background technique [0002] Projectors are widely used in various occasions, such as business offices, education and teaching, and home entertainment. At the same time, with the development of technology, projection equipment such as short-focus projection has gradually become an important display and entertainment equipment. As a part of the projection system, the curtain is often an important part of the display system. The function of the curtain is mainly to ensure the gain Good fit, good contrast, good color reproduction. The curtain is an important part of the projection system. The curtains include white plastic screens, gray screens, glass bead screens, pearl screens, metal screens, anti-ambient light PET screens, paint screens, etc. The better the screen, the more expensive it is. In this ca...

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a projector output mode switching method and system, aiming at solving the problem of the projector still being a constant projection in such different screen combinations in the prior art. Output mode, the effect on the screen is poor, and sometimes even the projected content cannot be seen clearly on the screen, which brings inconvenience to users
