摘要： The present disclosure relates to a computer implemented method and system for obtaining an image sensor exposure setting for use in capturing an image using a main flash. The method comprises the steps of obtaining first pre-image data related to a first pre-image captured using a predetermined first image sensor pre-image exposure setting, wherein the first pre-image is captured while emitting a flash of a predetermined first pre-flash energy; obtaining second pre-image data related to a second pre-image captured using a predetermined second image sensor pre-image exposure setting, wherein the second pre-image is captured while emitting a flash of a predetermined second pre-flash energy different than the first pre-flash energy; determining a flash effected area in the second pre-image in which a predetermined ratio of the image sensor pixel values have changed from the first pre-image; and determining the image sensor exposure setting for use in capturing the image based on the first and the second set of image senor pixel values in the flash affected area, the predetermined first and second image sensor pre-image exposure setting and a relation between a predetermined main flash energy, the energy of the predetermined first pre-flash and the energy of the predetermined second pre-flash, respectively.

摘要： Systems, apparatus, and methods for stabilization and blending of exposures. So-called Electronic Image Stabilization (EIS) techniques use image manipulation software to compensate for camera motion. Unfortunately, existing EIS techniques cannot compensate for artifacts introduced by low shutter speed (e.g., blurs). Various embodiments of the present disclosure generate stabilized images from multiple exposures. In one exemplary embodiment, the stabilized exposures are blended using a linear sum of the color data for each pixel of the image. By stabilizing each exposure and linearly summing the light information, the camera shake can be removed, and the subject motion blur can be controlled. The stabilization and blending techniques enable a mathematical emulation of a selected shutter angle from many high-speed exposures.

摘要： The technology disclosed relates to identifying an object in a field of view of a camera. In particular, it relates to identifying a display in the field of view of the camera. This is achieved by monitoring a space including acquiring a series of image frames of the space using the camera and detecting one or more light sources in the series of image frames. Further, one or more frequencies of periodic intensity or brightness variations, also referred to as ‘refresh rate’, of light emitted from the light sources is measured. Based on the one or more frequencies of periodic intensity variations of light emitted from the light sources, at least one display that includes the light sources is identified.

摘要： A solid-state imaging device, a method for driving the same, and an electronic apparatus can achieve a high dynamic range based on multiple exposure technique, where images captured with different exposure durations are combined, with it being possible to prevent motion artifacts and LED flickers. A pixel has a 4:0 configuration. The pixel is divided into, for example, four sub-pixels all of which have the same color (for example, G (green)). An access control part sets different charge integration periods and different charge storage starting times between photoelectric conversion parts PD of the sub-pixels and controls the charge integration periods such that they overlap each other. In other words, the access control part sets different charge integration periods and different charge storage starting times, the number of which corresponds to the number of sub-pixels having the same color, and controls the charge integration periods such that they overlap each other.

摘要： Imaging methods and imagers for image capture devices. Still images are captured by gathering ambient light data using an ambient light sensor of the image capture device, selecting a frame rate for the imager corresponding to the gathered ambient light data, determining optimal image capture parameters for the imager by executing an auto exposure algorithm with a processor using the selected frame rate as an initialization parameter for the auto exposure algorithm, and capturing a still image with the imager after execution of the auto exposure algorithm using the selected frame rate.

摘要： An autonomous vehicle is configured to detect an active turn signal indicator on another vehicle. An image-capture device of the autonomous vehicle captures an image of a field of view of the autonomous vehicle. The autonomous vehicle captures the image with a short exposure to emphasize objects having brightness above a threshold. Additionally, a bounding area for a second vehicle located within the image is determined. The autonomous vehicle identifies a group of pixels within the bounding area based on a first color of the group of pixels. The autonomous vehicle also calculates an oscillation of an intensity of the group of pixels. Based on the oscillation of the intensity, the autonomous vehicle determines a likelihood that the second vehicle has a first active turn signal. Additionally, the autonomous vehicle is controlled based at least on the likelihood that the second vehicle has a first active turn signal.
