Abstract: A method and system for processing image data having a first bit depth using at least one trained neural network configured to operate on data having a second bit depth, where the second bit depth is smaller than the first bit depth by generating a plurality of image data portions by splitting the image data. Each of the plurality of image data portions is encoded to produce a plurality of encoded image data portions having the second bit depth. The plurality of image data portions are then processed by at least one trained neural network, before being decoded and combined to produce composite image data. The composite image data is then output.

Abstract: A method for processing an image. The method comprises receiving intensity values for each of a plurality of images captured by an image sensor during a detection window. The method comprises identifying, using the intensity values, one or more transitions occurring during the detection window, the one or more transitions each comprising a transition between an image in which a maximum clipping criterion is not satisfied and an image in which the maximum clipping criterion is satisfied. The method comprises, based on the identified transitions, at least one of: adjusting an exposure level of the image sensor; and determining a tonemapping function having a tonemapping strength, and applying the tonemapping function to the intensity values of a current image to generate tonemapped intensity values, wherein the image sensor has a current exposure level when the current image is captured.

Abstract: An image signal processor, comprising an input module for obtaining input data from a camera, whereby the camera is arranged to capture a representation of a real-world environment. The image signal processor further comprises at least one adjustment module for compressing the input data and producing compressed input data, and a localization and mapping module arranged to generate one or more data points from the compressed input data. The image signal processor also comprises an output module for outputting at least the one or more data points.

Abstract: A computer-implemented method, a computer system configured to perform the method, and a non-transitory computer-readable storage medium are provided comprising instructions for executing the method are provided. The computer-implemented method comprises obtaining input video data including frames of input image data comprising first image data values expressed in an input color space. The first image data values are processed with a first and second color space conversion process to generate first processed image data and second processed image data respectively. The first processed image data and the second processed image data include image data values expressed in an output color space. Output image data is derived from both the first processed image data and the second processed image data.

Abstract: A method and apparatus for measuring depth using a time-of-flight (ToF) depth sensor is described. The apparatus includes an emitter configured to emit a signal towards a scene comprising one or more regions with light or sound, this emitter being controllable to adjust at least one of an intensity and a modulation frequency of the signal output from the emitter. The apparatus also includes a signal sensor, configured to detect an intensity of the signal from the emitter that has been reflected by the scene. A controller is configured to receive context information about the scene for depth capture by the time-of-flight depth sensor and to adjust at least one of the intensity and modulation frequency of the signal output by the emitter in dependence on the context information.

Abstract: A method for processing an image. The method comprises receiving intensity values of pixels for each of a plurality of images captured by an image sensor during a detection window. The method comprises identifying, using the intensity values, a plurality of transitions occurring at different times during the detection window, each transition of the plurality of transitions being identified on the basis of detecting intensity values of pixels that have been clipped in images between which such transitions may occur. The method comprises, based on identifying the plurality of transitions occurring during the detection window, at least one of: adjusting an exposure level of the image sensor; and determining a tonemapping function having a tonemapping strength, and applying the tonemapping function to the intensity values of a current image to generate tonemapped intensity values, wherein the image sensor has a current exposure level when the current image is captured.
