Abstract

The invention discloses a method for adjusting television picture size based on a user watching distance, comprising steps of setting an calculation method for calculating the nearest watching distance according to target television screen parameters, calculating a watching distance standard value which is stored in a television system, detecting the user watching distance at intervals by an infrared detector, storing practical data of the watching distance by the television system, when the practical data is smaller than the watching distance standard, obtaining current program types broadcasted by the intelligent television according to EPG or a network by the television system, and when the program types belongs to children programs, proportionally downsizing the television picture according to the watching distance. The method for adjusting television scenes size based on user watching distance guarantees life quality of people and protects the user body from damage.

Description

technical field [0001] The invention relates to a smart TV, in particular to a method for adjusting the size of a TV screen based on a user viewing distance. Background technique [0002] The overall transformation of my country's cable digital TV is in full swing. During the transformation process from traditional analog to modern digital mode, the government and all aspects of the industry chain (involving equipment suppliers, content providers and integrators, network operators) Businesses, etc.) are engaged in a war without gunpowder, and they are all moving forward in the process of groping; with the continuous advancement of technology in the TV industry, the myopia rate of children in society is getting higher and higher, and the body is exposed to various pollution. One of the factors that greatly increases the myopia rate is because of the increase in electronic products, and the use of electronic products since childhood. It is quite necessary to appropriately impro...
