Dual-mode projection device and projection method, and storage medium

Abstract

The invention provides a dual-mode projection device and projection method, and a storage medium. Two projection modules are combined with an image processor, the number of columns of original image data is increased by using the image processor, and the two projection modules are cooperatively used to read a part of new image data, meanwhile projection images of the new image data of each part are projected on the horizontal direction, the projection images corresponding to the new image data of each part are spliced into a target project image, the final output image pixel is doubled on thehorizontal direction, the brightness is doubled, the horizontal image area is doubled as well, the logic speed from an image processing process to a projection process is improved, and the energy consumption is reduced, therefore, the dual-mode projection device and projection method are particularly suitable for large-frame miniature image output devices, such as micro-laser projection devices.

Description

technical field [0001] The present invention relates to the field of projection technology, in particular to a dual-mode projection device, an image projection method thereof, and a computer-readable storage medium. Background technique [0002] With the development of science and technology, projection devices are becoming more and more miniaturized and portable. Therefore, laser projection devices have emerged as the times require. Due to their small size and high brightness, laser projection devices have attracted widespread attention and have been put into commercial production. However, even if the laser brightness of the laser projection device is high, under white light or in areas with strong light, the picture projected by the laser projection device is relatively unclear, which also affects the light intensity and clarity of the projection device. Come to great challenge. [0003] How to improve the brightness and definition of the laser projection device without ...

Problems solved by technology

[0006] However, since lasers lose a lot of energy during imaging, the greater the number of lasers, the more energy will be lost. Relying on simply increasing the number of lasers cannot achieve the ideal brightness and clarity, but instead makes the heat concentration of the laser projection device Larger, causing serious heat dissipation problems and increasing the risk factor
