Abstract

The invention discloses an adaptive adjustment method for video playing. The method includes acquiring facial feature data of target audiences, determining a viewing distance of the target audiences according to the facial feature data of the target audiences, calculating an image output range and a screen output brightness of the video playing according to the viewing distance of the target audiences to obtain screen output parameters, calling function interface functions according to the screen output parameters and adjusting the output of the video playing through the functions. The invention further discloses a digital television terminal. By means of the method and the digital television terminal, output parameters such as the image output range and the screen output brightness of the video playing can be adaptively adjusted according to the viewing distance of a television user when the user watches the television, a comfortable and physically beneficial video watching effect can be provided for the television user, and the vision health of the television user can be well guaranteed.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for adaptive adjustment of video playback. Background technique [0002] At present, large-screen flat-panel TVs are popular among TV users due to their beautiful appearance and large screens. LCD TVs and plasma TVs have stable images without flickering and very little radiation, and even claim to have no radiation. This makes most people, especially children who lack restraint, think that TV has no radiation, and often watch TV programs at close range without a reasonable viewing distance, which has certain hidden dangers to visual health. [0003] Observations and experiments have found that whether the relationship between the size of the image output rectangle on the screen, the brightness of the screen output, and the TV user's viewing distance is coordinated will affect the viewing effect of TV users watching video programs and the user's vision health. Too la...
