Abstract

The present application provides a multi-zone projection device and a multi-zone projection method. The multi-zone projection device includes: an image light projection board, the image light projection board includes a first projection area and a second projection area, and the first projection area The image light used for imaging is emitted by the second projection area; the optical path compensation part is arranged on the propagation path of the image light, and the optical path compensation part includes different optical path compensation amounts The first compensation area and the second compensation area, the first compensation area and the second compensation area correspond to the first projection area and the second projection area respectively; imaging lens group, the imaging lens A group images the image light transmitted through the first compensation area to transmit the first imaging light, and images the image light transmitted through the second compensation area to transmit the second imaging light.

Description

technical field [0001] The present application relates to the field of image data processing and generation, and more specifically, relates to a multi-region projection device and a multi-region projection method. Background technique [0002] As one of common picture generation units (Picture Generation Unit, PGU), projection devices are widely used in various application scenarios. A common projection device generally uses a digital micro-mirror device (Digital Micro-mirror Device, DMD) as the core unit of the PGU. The optical signal emitted by the DMD is processed by the optical system and then projected onto the screen to display the image. [0003] Projection devices are currently also widely used in motor vehicles to implement Head-Up Displays (HUDs). AR-HUD integrates augmented reality technology and HUD technology well, and can help the driver analyze the surrounding driving environment without affecting the driver's perception of the real driving environment. In ...
