The technology disclosed herein involves using a transformation curve to modify colors of images so that those images are more easily viewed by persons with a color vision deficiency (CVD). The transformation curve is applied to spectral versions of images in which each pixel has a spectral representation to modify the spectral versions of the images. A spectral version of an image is modified by, for each pixel of the spectral version of the image, modifying intensities of one or more wavelengths by applying the one or more wavelengths to the transformation curve, which transforms the intensities from source wavelengths to destination wavelengths. The modified spectral version of the image is then modified to a modified version of the image in a color space, such as the RGB color space.

Image processing using color vision deficiency compensation

A method dynamically selects one of a first sampling order and a second sampling order for a ray trace of pixels in a tile where the selection is based on a motion vector for the tile. The sampling order may be a bowtie pattern or an hourglass pattern.

Adaptive pixel sampling order for temporally dense rendering

The present invention relates to a method for determining a position of a first device with respect to a second device. According to the method, control data indicative of a receive property of at least one signal received from the first device () by a second device (-) using a plurality of receiver chains (-) is established. At least one receive characteristic of the plurality of receiver chains (-) differs for at least two receiver chains of the plurality of receiver chains (-). Based on the control data, positioning information for the first device () is determined.

Determining a position of a device with respect to another device

Image quality can be improved by rendering the image based on an importance map that indicates regions of the image that will benefit from more samples. Adaptive sampling determines a number of samples for each pixel of the image using a target sampling rate and the importance map for the image. The number of samples for each pixel needs to be a non-negative integer value, so the per-pixel sampling rates are quantized using per-pixel random values. The resulting quantized sampling rates provides a distribution of samples that closely matches the importance map. The per-pixel random values may vary over time so that the average of the distribution more closely matches the importance map.

Adaptive sampling at a target sampling rate

A method dynamically selects one of a first sampling order and a second sampling order for a ray trace of pixels in a tile where the selection is based on a motion vector for the tile. The sampling order may be a bowtie pattern or an hourglass pattern. Subframes generated based on the sampling order are communicated over a bus along with motion vectors for tiles of the subframes.

Monitoring camera

A top cover assembly for a monitoring camera assembly that includes a mounting portion arranged for attachment to a mounting base for a monitoring camera, a dome window arranged on the mounting portion and a lining arranged at an inside of the dome window, the lining having a camera view opening adapted to a field of view of the monitoring camera and being rotatable in relation to the mounting portion, and the lining having a guiding portion arranged for engagement with a camera mounting bracket on the mounting base to position the lining in relation to the monitoring camera such that the camera view opening covers the field of view of the monitoring camera, when mounting the top cover assembly on the mounting base, thereby allowing the mounting portion to be rotated in relation to the lining into a position for attaching the mounting portion to the mounting base.
