Abstract: An auto exposure method for an image capture device includes the steps of gathering ambient light data using an ambient light sensor of the image capture device, selecting a frame rate corresponding to the gathered ambient light data, and determining an optimal image capture frame rate for the image capture device. The auto exposure method determines the optimal image capture frame rate by executing an auto exposure algorithm with a processor using the selected frame rate as an initialization parameter for the auto exposure algorithm.
Abstract: Provided are a camera capable of preventing an erroneous operation with a compact configuration and has high operability, a setting method of the camera, and a setting program of the camera. A touch sensor is provided on a top surface of an operation dial. A change in a setting value by the operation dial is switched between valid and invalid according to a detection result of the touch sensor, and an operation by the operation dial becomes possible only in a case where the change in the setting value is valid. A setting value of an item to be set by the operation dial is displayed on a sub-display provided near the operation dial.
Abstract: A Time-of-Flight (TOF) technique is combined with analog amplitude modulation within each pixel in a pixel array using multiple Single Photon Avalanche Diodes (SPADs) in conjunction with a single Pinned Photo Diode (PPD) in each pixel. A SPAD may be shared among multiple neighboring pixels. The TOF information is added to the received light signal by the analog domain-based single-ended to differential converter inside the pixel itself. The spatial-temporal correlation among outputs of multiple, adjacent SPADs in a pixel is used to control the operation of the PPD to facilitate recording of TOF values and range of an object. Erroneous range measurements due to ambient light are prevented by stopping the charge transfer from the PPD—and, hence, recording a TOF value—only when two or more SPADs in the pixel are triggered within a pre-defined time interval. An autonomous navigation system with multi-SPAD pixels provides improved vision for drivers under difficult driving conditions.

Abstract: Systems and methods are disclosed for managing power use of a camera and/or camera system. In response to a wakeup trigger, contents of a scene are captured by the camera. Based on a received energy budget for the camera, a scene analysis is performed on the scene, where the contents of the scene are analyzed according to one or more analytics models. Based on the output of the one or more analytics models and the received energy budget for the camera, it is determined whether the camera should continue capturing the contents of the scene or enter a power state lower than a previous power state (e.g., go to sleep).

Abstract: Provided are methods, systems, and computer-program products for determining one or more settings of a content capture device. In some examples, to determine the one or more settings, luma values of pixels of an image from the content capture device may be identified. Objects in the image and information associated with the objects may also be identified. The information associated with the objects may be divided into categories of the information. And using the objects and the information, a separate weight array for each category of the information may be computed. The separate weight arrays may be combined to create a total weight array to augment the luma values. The augmented luma values may be aggregated to compute a weighted luma average for the image. Based upon a difference of the weighted luma average and a target, the one or more settings may be adjusted.
