Abstract

The application provides a multi-region imaging device and method. The multi-zone imaging device includes an image light projection plate, an optical path compensation section and an imaging lens group. The image light projection plate includes a first region and a second region that do not overlap each other. The first region and the second region emit image light used for imaging. The optical path compensation section is arranged on a propagation path of the image light emitted by the second region. The image light emitted by the second region is transmitted by the optical path compensationsection, and optical path compensation is carried out thereon. The imaging lens group carries out imaging on the image light, which is emitted by the first region, to transmit first imaging light, andcarries out imaging on the image light, which is transmitted by the optical path compensation section, to transmit second imaging light. The first imaging light and the second imaging light have different imaging surfaces.

Description

technical field [0001] The present application relates to the field of image data processing and generation, and more particularly, to a multi-region imaging device and 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 light signal emitted by the image light projection board containing the DMD chip 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 vehicles to implement Head-Up Displays (HUDs). Currently, vehicle-mounted HUDs include various types, such as W-HUD, C-HUD, and AR-HUD. [0004] AR-HUD integrates augmented reality technology and HUD technology well, and can help the driver analyze the surround...
