Abstract

The embodiment of the invention provides a projection player, a playing method thereof and a computer storage medium. The playing method comprises the steps of determining a preset standard test imageaccording to the distance between the projection player and a playing projection area, projecting the standard test image to the playing projection area, and obtaining a reflection image of the standard test image after reflection in the playing projection area; comparing the standard test image and the reflection image and determining an abnormal area of the playing projection area; determininga pixel area to be compensated in a to-be-played image, corresponding to the abnormal area; making compensation for input signals corresponding to the pixel area to be compensated according to presetcompensation parameters, and projecting the image after compensation to the playing projection area to be played. Due to compensation for the input signals corresponding to the pixel area to be compensated, image observation distortion caused by rough and uneven surface of the playing projection area can be reduced.

Description

technical field [0001] The present invention relates to the technical field of intelligent playback devices, in particular to a projection playback device, a playback method thereof, and a computer storage medium. Background technique [0002] With the development of smart playback devices, the projection function has become an indispensable function of smart playback devices and home entertainment playback devices.
