Embodiment Construction

[0048] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0049] The present invention senses ambient light through a light sensor located at the top of the front of the mobile phone, acquires relevant parameters, and automatically adjusts the brightness and definition of a projected picture. The displacement sensor located on the back cover of the mobile phone senses the distance between the mobile phone and the projection screen, automatically adjusts the size of the projection screen, and realizes the mobile phone fill light projection operation through the operation of related modules.

Abstract

The invention discloses a method and a device for projecting by a light-compensating lamp of a mobile phone, relating to the sensing technology and the photographing-projecting technology in the communication industry. The method comprises the following steps of: acquiring the light ray parameters of an ambient environment in real time, and controlling the mobile phone to adjust the brightness of the projected picture according to the obtained light ray parameters; acquiring the distance data between the mobile phone and a projecting screen in real time, and controlling the mobile phone to adjust the size of the projected picture according to the obtained distance data; and performing projecting display processing on the to-be-projected mobile phone screen display interface to obtain a projecting digital signal, performing signal conversion processing on the projecting digital signal to obtain a projecting video light signal for projecting, and projecting onto the projecting screen via the lens of the light-compensating lamp of the mobile phone. In the method and the device disclosed by the invention, the mobile phone is utilized for projecting without the need of connecting a projector, thus improving the mobile working capacity of the mobile phone.

Description

technical field [0001] The invention relates to sensing and camera projection technology in the communication industry, in particular to a mobile phone fill light projection method and related devices. Background technique [0002] With the continuous development of smart phones, users' demand for mobile office work is also increasing, especially the portability and real-time performance brought by mobile phone projection. At present, there are three main projection technologies: liquid crystal projection technology (Liquid Crystal Display, LCD), digital light processor projection technology (Digital Lighting Process, DLP), cathode ray tube projection technology (Cathode Ray Tube, CRT). [0003] The technology of LCD projector is transmissive projection technology, which is the most mature at present. The color reproduction of the projection screen is real and vivid, the color saturation is high, and the light utilization efficiency is very high. Compared with the DLP proje...
