  • Patent number: 11983848
    Abstract: Aspects of the disclosure provide a frame processor for processing frames with aliasing artifacts. For example, the frame processor can include a super-resolution (SR) and anti-aliasing (AA) engine and an attention reference frame generator coupled to the SR and AA engine. The SR and AA engine can be configured to enhance resolution and remove aliasing artifacts of a frame to generate a first high-resolution frame with aliasing artifacts and a second high-resolution frame with aliasing artifacts removed. The attention reference frame generator can be configured to generate an attention reference frame based on the first high-resolution frame and the second high-resolution frame.

  • Publication number: 20240085172
    Abstract: The device includes a projecting device, an image sensor and a computing circuit. The projecting device provides a light beam having a predetermined pattern that is projected onto an object. The image sensor receives the light beam reflected from the object to generate an image. The computing circuit compares the image with a first ground-truth image and a ground-truth image to generate a first depth value and a second depth value respectively. The first and second depth values are combined to generate a depth result.
