  • Publication number: 20230021016
    Abstract: Systems and techniques described herein relate to techniques for improving image detection. In some examples, aspects relate to systems and techniques for improving image detection by performing tracking of objects within captured image frames. A process can include obtaining, from an image capture device, a first image frame including an object. The process can further include determining, using an object detector, an object validation score associated with detection of the object in the first image frame, and determining the object validation score is less than a validation threshold. Based on the object validation score being less than the validation threshold, the process can include tracking the object for one or more image frames received subsequent to the first image frame.

  • Publication number: 20230015621
    Abstract: The present disclosure provides systems, apparatus, methods, and computer-readable media that support improved image signal processing, particularly in low-light or high dynamic range (HDR) scenes. The image processing techniques may include performing two automatic exposure control (AEC) operations, in which a first AEC operation targets obtaining good conditions for autofocus (AF) operation, and a second AEC operation follows the AF operation and targets obtaining good conditions for an image capture. The image processing techniques may also include communication between the AEC operations and AF operations to coordinate the operations by locking and releasing exposure levels and focus positions as part of the image signal processing.

  • Publication number: 20230012219
    Abstract: The present disclosure provides systems, apparatus, methods, and computer-readable media that support multi-frame depth-of-field (MF-DOF) for deblurring background regions of interest (ROIs), such as background faces, that may be blurred due to a large aperture size or other characteristics of the camera used to capture the image frame. The processing may include the use of two image frames obtained at two different focus points corresponding to the multiple ROIs in the image frame. The corrected image frame may be determined by deblurring one or more ROIs of the first image frame using an AI-based model and/or local gradient information. The MF-DOF may allow selectively increasing a depth-of-field (DOF) of an image to provide focused capture of multiple regions of interest, without causing a reduction in aperture (and subsequently an amount of light available for photography) or background blur that may be desired for photography.

  • Publication number: 20220392036
    Abstract: In general, techniques are described regarding fusing or combining frames of image data to generate composite frames of image data. Cameras comprising camera processors configured to perform the techniques are also disclosed. A camera processor may capture multiple frames at various focal lengths. The frames of image data may have various regions of the respective frame in focus, whereas other regions of the respective frame may not be in focus, due to particular configurations of lens and sensor combinations used. The camera processor may combine the frames to achieve a single composite frame having both a first region (e.g., a center region) and a second region (e.g., an outer region) in focus.

  • Publication number: 20220385873
    Abstract: A multi-point measurement of a scene captured in an image frame may be used to process the image frame, such as by applying white balance corrections to the image frame. In some examples, the image frame may be segmented into portions that are illuminated by different illumination sources. Different portions of the image frame may be white balanced differently based on the color temperature of the illumination source for the corresponding portion. Infrared measurements of multiple points in the scene may be used to determine a characteristic of the illumination source of different portions of the scene. For example, a picture that includes indoor and outdoor portions may be illuminated by at least two illumination sources that produce different infrared measurements values. White balancing may be applied differently to these two portions to correct for color temperature of the different sources.
