Abstract: Systems and techniques are described herein for enhancing depth representations based on amplitudes of time-of-flight signals. For instance, a computing device can obtain a depth representation of a scene. The depth representation includes depth values based on a time of flight (ToF) signal. The computing device can obtain amplitude values corresponding to the depth values of the depth representation. The amplitude values are based on the ToF signal. The computing device can determine a mask for the depth values based on the depth values and the amplitude values.

Abstract: Systems and techniques are provided for processing images. For example, a process can include obtaining a first color image including first one or more pixels from a first image sensor and obtaining a second color image including second one or more pixels from a second sensor, the second color image including infrared (IR) information from a second image sensor. The process can include determining a transformation between colors associated with the first one or more pixels and colors associated with the second one or more pixels based on a comparison associated with the first one or more pixels and the second one or more pixels. The process can include generating a color corrected image at least in part by transforming the second color image including IR information to a color corrected image based on the determined transformation.

Abstract: Imaging systems and techniques are described. An imaging system determines, based on image data of a scene received from an image sensor, a first plurality of pixel values corresponding to a first electromagnetic (EM) frequency domain and a second plurality of pixel values corresponding to a second EM frequency domain. The imaging system reduces the first plurality of pixel values using a plurality of cross-domain contamination values (based on the second plurality of pixel values) to generate a third plurality of pixel values. The imaging system determines a reconstructed pixel value based on a combination of at least an overexposed pixel value of the first plurality of pixel values and a corresponding pixel of the third plurality of pixel values. The imaging system outputs a reconstructed image that includes the reconstructed pixel value and a subset of the third plurality of pixel values.

Abstract: The present disclosure relates to methods and apparatus for image processing. For example, disclosed techniques facilitate a sparse infrared pixel design for image sensors. Aspects of this disclosure include an image sensor including a pattern of pixels, the pattern of pixels including a set of visible light pixels and a set of infrared light pixels. The image sensor may be configured to generate visible light data and infrared light data based on received light. Aspects of the present disclosure also include a processor coupled to the image sensor. The processor may be configured to generate a configurable mask based on the pattern of pixels of the image sensor, and where values of the configurable mask correspond to pixel locations of the image sensor.

Abstract: Apparatus for generating images using a mechanical infrared cut-off switch are disclosed herein. An example apparatus including an optical system for generating images includes a mechanical infrared light filter movable between a first position and a second position. The mechanical infrared light filter may be configured to allow infrared light to pass through the optical system while in the first position and configured to filter out infrared light from the optical system while in the second position. The example apparatus also includes an imaging sensor including imaging pixels and infrared pixels, and may be configured to receive light from the optical system. Additionally, the example apparatus includes a processor configured to receive visible light data and infrared light data from the image sensor. The processor may further be configured to generate a combined image based on the visible light data and the infrared light data.
