Perspective Correction With Depth Clamping - A simplified explanation of the abstract
This abstract first appeared for US patent application 18612967 titled 'Perspective Correction With Depth Clamping
The patent application describes a method for performing perspective correction of an image captured by a device with an image sensor, display, processors, and memory.
- The method involves capturing an image of a physical environment using the image sensor.
- It obtains depths associated with pixels of the image and generates a clamped depth map based on these depths.
- A display image is then generated by transforming the image based on the clamped depth map and the difference in perspectives between the image sensor and the user.
- The final display image is shown on the display.

Original Abstract Submitted
In one implementation, a method of performing perspective correction of an image is performed by a device including an image sensor, a display, one or more processors, and non-transitory memory. The method includes capturing, using the image sensor, an image of a physical environment. The method includes obtaining a plurality of depths respectively associated with a plurality of pixels of the image of the physical environment. The method includes generating a clamped depth map of the image of the physical environment based on the plurality of depths, wherein each element of the clamped depth map has a depth value above or equal to a depth threshold. The method includes generating a display image by transforming, using the one or more processors, the image of the physical environment based on the clamped depth map and a difference between a perspective of the image sensor and a perspective of a user. The method includes displaying, on the display, the display image.
