Embodiment Construction

[0049] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050]In practical applications, the color ratio of the projection lens itself is often ignored, or cannot be measured during the debugging process, because the light transmitted by the same type of lens will vary according to the different emission source capabilities, that is, the light intensity. Different optical systems (the optical system includes DMD (Digital Micromirror Device, digital micromirror device) DMD is an array composed of multiple high-speed digital light reflection switches. DMD is composed of many small aluminum reflective mirrors. How much is determined by the display resolution, a small lens corresponds to a pixel, DMD has high reflectivity and high contrast, the object is imaged on the DMD device, through the pixel-level controllable characteristics of the DMD device and its high-speed flip freq...

Abstract

The invention discloses a projection lens duty ratio adjusting method, which comprises the steps of receiving a duty ratio adjusting instruction, and determining a projection lens corresponding to theduty ratio adjusting instruction; emitting a test light source to the projection lens, and obtaining a color coordinate actual value formed by irradiating the projection lens by the test light source; comparing the actual color coordinate value with a theoretical color coordinate value corresponding to the test light source to obtain a color coordinate deviation value, and adjusting an initial duty ratio corresponding to the projection lens according to the color coordinate deviation value to obtain a target duty ratio; and generating a projection light source corresponding to the target dutyratio, and irradiating the projection lens through the projection light source to form a projection image. The invention further discloses a projection lens duty ratio adjusting device and equipmentand a computer storage medium. The duty ratio is adjusted according to the color coordinate deviation of the projection lens, the projection image influenced by the color of the projection lens is avoided, and the projection image quality of the projection lens is improved.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to a method, device, equipment and computer storage medium for adjusting the duty cycle of a projection lens. Background technique [0002] With the advancement of technology and the innovation of production technology, there are more and more application scenarios for projection display. [0003] In order to ensure the projection quality of the projection equipment, the projection equipment needs to be tested and adjusted before leaving the factory. However, when the projection equipment is tested and adjusted, the color ratio of the projection lens itself in the projection equipment is often ignored, that is, the projection in the projection equipment The lens itself has color, which will cause the image projected by the projection lens to deviate from the correct color value. The current color adjustment method of the optical system cannot adjust the technical problem of co...
