    摘要: A readout frequency of a sensor of a digital image capturing device is set based on a frequency of alternating current (AC) mains so that a readout period of the sensor of the digital image capturing device is not an integer multiple of a flicker period. The flicker period is equal to half of a period of the AC mains. A first image frame and a second image frame are captured using the sensor of the digital image capturing device. The second image frame is captured later in time than the first image frame. Whether flicker has occurred in the first and second image frames due to a periodic fluctuation of light emitted by a light source powered by the AC mains is detected by comparing a brightness of an area of the first image frame to a brightness of a corresponding area of the second image frame.

    摘要: A focus lens is moved to a position within a range of focus lens positions. A video frame is captured with the focus lens at that position. The magnification of the first video frame is altered according to a maximum magnification threshold associated with the range of focus lens positions.

    摘要: A machine-implemented method of generating a stabilized video sequence includes receiving an input video sequence captured by an image capture device. The input video sequence includes a plurality of pairs of successive frames. Motion sensor data indicative of motion of the image capture device while the input video sequence was being captured is received. A set of matching features for each pair of successive frames is identified. Global motion features are identified in each set of matching features and qualified based on the motion sensor data. The global motion features are indicative of movement of the image capture device. A stabilized video sequence is generated based on the input video sequence and the identified global motion features.

    摘要: A method is disclosed for capturing one or more images that include a lightning strike using an image capturing device. The method is performed by one or more processors of the image capturing device. The one or more processors automatically capture a plurality of images during a period of time using the lens of the device. Each of the plurality of images is processed to detect a presence of lightning within each image. Each image is processed based, at least part, on two consecutive captured images. Images that have been determined to include the presence of lightning are stored in a memory resource of the image capturing device.
