MULTI-CAMERA SYSTEM USING FOLDED OPTICS

摘要

Described herein are methods and devices that employ a plurality of image sensors to capture a target image of a scene. As described, positioning at least one reflective or refractive surface near the plurality of image sensors enables the sensors to capture together an image of wider field of view and longer focal length than any sensor could capture individually by using the reflective or refractive surface to guide a portion of the image scene to each sensor. The different portions of the scene captured by the sensors may overlap, and may be aligned and cropped to generate the target image.

主权项

1. An image capture system for capturing an image of a target scene, the system comprising:
a plurality of cameras positioned to capture image data representing a plurality of portions of the target scene; a first lens positioned to focus light received from the target scene as the light propagates towards the plurality of cameras; each of the plurality of cameras comprising
a first optical axis, wherein the first lens is positioned along the first optical axis,a primary surface positioned so as to receive light comprising one of the plurality of portions of the target scene propagating along the first optical axis and reflect the received light along a second optical axis,a lens assembly comprising at least a second lens, the lens assembly positioned to receive and refract the light propagating along the second optical axis,an image sensor positioned to receive the light from the lens assembly, the sensor configured to capture a portion of the image data representing the one of the plurality of portions, anda diaphragm positioned between the first lens and the image sensor; a processor; and a memory storing instructions that configure the processor to generate the image of the target scene based at least partly on the image data comprising each of the plurality of portions of the target scene.
