Image output method and projection device

Abstract

The invention provides an image output method and projection devices. The method comprises the following steps of acquiring original resolutions of at least two projection devices carrying out splicing and a resolution of an overlapping region; according to the original resolutions of at least two projection devices and the resolution of the overlapping region, acquiring an aspect ratio of a projection range formed through carrying out splicing by the at least two projection devices; displaying an original image; acquiring an interception image selected by a user based on the original image and determining an original aspect ratio of the interception image; according to the original aspect ratio of the interception image and the aspect ratio of the projection range, calculating a display area of the interception image in the projection range so that the aspect ratio of the interception image, which is displayed in the projection range, maintains the original aspect ratio of the interception image when the interception image is displayed in the projection range; and displaying the interception image on a display area in the projection range.

Description

technical field [0001] The invention relates to the field of projection splicing, in particular to an image output method and a projection device. Background technique [0002] When two projection devices are used for splicing images, overlapping parts will be formed. Assuming that the original resolution of the projection devices is 1920*1080 and the resolution of the overlapping part is X*1080, the projection range is (1920*2-X )*1080, when the overlapping part is small, the ratio of the projection area is about 32:9, and the screen is too long. If the original image projected is not in this ratio, the original image will be projected at the ratio of the spliced ​​projection area, and the two projection devices will be displayed after splicing Compared with the original image, the image will inevitably be distorted. If you want to maintain the proportion of the original image, you must sacrifice the display range, that is, black borders will appear on the image. Therefore...
