Abstract: Imaging systems and techniques are described. An imaging system includes a multi-domain image sensor that is sensitive to a first electromagnetic frequency domain (e.g., visible light) and a second electromagnetic frequency domain (e.g., infrared). The imaging system blends images of a scene to generate a blended image of the scene that represents the scene according to the first electromagnetic frequency domain. At least one image of the images is captured using a first image capture setting (e.g., a first ISO). The imaging system reduces pixel values in the blended image by adjustment values to generate an output image. The adjustment values are based on a representation of the scene according to a second EM frequency domain from an additional image of the scene that is captured using a second image capture setting (e.g., a second ISO).

Abstract: Imaging systems and techniques are described. An imaging system causes a display to display light according to a predefined pattern. The imaging system receives image data of a scene from an image sensor. The image data is captured using the image sensor while the display is configured to display the light according to the predefined pattern. The imaging system processes the image data to generate at least one image frame of the scene based on detection of the predefined pattern in the image data. The imaging system outputs the at least one image frame of the scene.

Abstract: Systems and techniques are described for determining one or more lens positions. For instance a process can include moving a lens to a first lens position, determining a first light focus value for a first image captured at the first lens position, determining a first infrared (IR) focus value for the first image captured at the first lens position, determining whether the first IR focus value exceeds the first light focus value, moving the lens to a second position based on whether the first IR focus value exceeds the first light focus value, determining a second light focus value for a second image captured at the second position, determining a second IR focus value for a second image captured at the second position, and determining a focused lens position based on the second light focus value, the second IR focus value, and a threshold focus value.

Abstract: Imaging systems and techniques are described. An imaging system can receive image data from an image sensor with different sets of photodetectors sensitive to different electromagnetic (EM) frequency domains. The imaging system determines, based on image data of a scene received from the image sensor, a first focus setting for focusing on the scene using the image sensor in the first domain. The imaging system determines, based on the first focus setting and a difference between respective characteristics of the first domain and a second domain, a second focus setting for focusing on the scene using the image sensor in the second domain. The imaging system causes the image sensor to capture a first image of the scene in the first domain according to the first focus setting, and to capture a second image of the scene in the second domain according to the second focus setting.

Abstract: This disclosure provides systems, methods, and devices for image capture and image process that support staggered high dynamic range (HDR) using image frames captured at different frame rates. In a first aspect, a method of image capture includes configuring a camera for image capture at a first frame rate; receiving, from the camera, first image data captured at the first frame rate; configuring the camera for image capture at a second frame rate higher than the first frame rate; receiving, from the camera, second image data captured at the second frame rate; and determining at least one output image frame based on the first image data and the second image data. Other aspects and features are also claimed and described.

Abstract: Systems and techniques are provided for selecting a camera from a plurality of cameras. For example, a process can include obtaining an image from a camera. In some cases, the process can include determining a depth of field (DOF) range associated with a scene captured in the image. In some aspects, the process can include comparing the DOF range associated with the scene captured in the image with one or more DOF ranges of respective cameras of a plurality of cameras. In some examples, the process can include determining a selected camera from the plurality of cameras based on comparing the DOF range associated with the scene captured in the image with respective one or more DOF ranges of each camera of the plurality of cameras.

Abstract: Aspects relate to noise processing of image frames for video. An example device is configured to perform operations including receiving a sequence of image frames for a digital video, determining an image quality metric of a first image frame from the sequence of image frames, and determining a number of image frames from the sequence of image frames to be blended based on the image quality metric (with the number of image frames including the first image frame). The operations also include blending the number of image frames to generate a blended image frame of the digital video. The image quality metric may include a light intensity metric (such as a luminance metric measured during an autoexposure operation) or a sharpness metric (such as a focus metric measured during an autofocus operation).
