Image correction device, image correction method, and projection device

Abstract

The disclosure, which relates to the field of the projection display technology, provides an image correction device, an image correction method, and a projection device. The image correction device is composed of a light splitting module, a polarization state adjustment module, an image acquisition module, and a correction module. The light splitting module is used for splitting incident image light into a transmission beam and a reflection beam; the polarization state adjustment module is used for adjusting the polarization state of the transmission beam to form a first image and the polarization state of the reflection beam to form a second image; the image acquisition module is used for obtaining the first image and the second image; and the correction module is used for determining correction data based on the first image and the second image and controlling the light splitting module to correct the first image and the second image for position alignment and boundary overlapping based on the correction data. On the one hand, the image is obtained accurately and image correction is realized based on the image position, so that the light beam crosstalk phenomenon is improved andthe watching experience is enhanced; and on the other hand, automatic correction is realized and the manual operation is removed, so that the operating costs are lowered.

Description

technical field [0001] The present disclosure relates to the technical field of projection display, and in particular, to an image correction device, an image correction method, and projection equipment. Background technique [0002] With the development of film projection technology, automation has been extended to most equipment including control and monitoring equipment, and even the action of switching field lights according to projection requirements has been automatically controlled. However, a kind of stereoscopic display device which is very popular in theaters is still in the stage of manual adjustment and correction. The stereoscopic display device includes traditional three-light path and traditional two-light path stereoscopic display devices. Difficult to debug.

Problems solved by technology

However, a kind of stereoscopic display device which is very popular in theaters is still in the stage of manual adjustment and correction. The stereoscopic display device includes traditional three-light path and traditional two-light path stereoscopic display devices. difficult to debug

[0003] Usually, most automated theaters only have one projectionist, so it is difficult to detect all the equipment every day. It is not discovered until the equipment has serious beam crosstalk, which seriously affects the 3D experience of moviegoers.

At present, these devices cannot be automated and need to be operated manually, resulting in inconvenient management and low efficiency.
