Embodiment Construction

[0051] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] One of the core concepts of the embodiments of the present application is that, during the process of projecting the target image sequence, the brightness information of each first position point projected to the projection area is collected, and the scanned images constituting the target image sequence are confirmed according to the collected brightness information Correction coordinates in , which are used to correct the target image sequence.

[0053] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a projection correction method of the present application, which may specifically include the following steps:

[0054] Step 101, projecting the target image sequence to...

Abstract

The invention discloses a projection correction method and apparatus and a laser television. The projection correction method provided by one embodiment of the invention comprises the following steps: projecting a target image sequence to generate projection imaging covering a preset projection area, wherein the target image sequence is a sequence formed by multiple scanning images, the preset projection area is provided with a plurality of preset first position points; obtaining target brightness information of the plurality of first position points during projection; by use of the target brightness information, determining correction coordinates in the scanning images; and correcting the target image sequence by use of the correction coordinates. According to the embodiments of the invention, a user does not have to adjust the position of a projector, and instead, the projector automatically corrects images to be projected so that the projector projection imaging can be easily debugged without professional debugging personnel.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a projection correction method, a projection correction device and a laser television. Background technique [0002] The current projection system generally consists of a projector and a screen. A projector projects an image onto a screen, and alignment of the projector's projected image with the screen is usually a manual process. For professional debuggers, precise alignment is a relatively time-consuming and cumbersome process, and for ordinary users who are not familiar with projection equipment, it is even more difficult. Contents of the invention [0003] In view of the above problems, the embodiments of the present application are proposed to provide a projection correction method, a corresponding projection correction device, and a laser television that overcome the above problems or at least partially solve the above problems. [0004] In order to ...
