Abstract: Techniques for generating a high resolution full color output image from lower resolution sparse color input images are disclosed. A camera generates images. The camera's sensor has a sparse Bayer pattern. While the camera is generating the images, IMU data for each image is acquired. The IMU data indicates a corresponding pose the camera was in while the camera generated each image. The images and IMU data are fed into a motion model, which performs temporal filtering on the images and uses the IMU data to generate a red-only image, a green-only image, a blue-only image, and a monochrome image. The color images are up-sampled to match the resolution of the monochrome image. A high resolution output color image is generated by combining the up-sampled images and the monochrome image.

Abstract: The present document describes an electronic device with a structural midframe and associated methods. The architectural design of the electronic device (e.g., a security camera) is such that its components are assembled onto the midframe to form a subassembly and the housing is assembled after the subassembly.

The midframe can also include a hinge-bearing surface forming a portion of a ball joint for supporting rotational movement of the electronic device. Accordingly, the electronic device uses the midframe, rather than the housing, as a structural member.
