Abstract: Image capture devices and methods may be used to pre-buffer media storage. The pre-buffering method includes recording an image capture segment in a circular buffer. The circular buffer includes a number of recordable segments. The pre-buffering method includes determining whether a key moment command is received. If a key moment command is not received, the method includes recording a next image capture segment in a next adjacent recordable segment of the circular buffer if the next adjacent recordable segment of the predetermined number of recordable segments is available. If a key moment command is not received, the method includes overwriting an oldest recordable segment if the next adjacent recordable segment of the predetermined number of recordable segments is not available. If a key moment command is received, the pre-buffering method includes marking a wrap point in the circular buffer and switching from recording in the circular buffer to linear recording.

Abstract: Image capture devices and methods may be used to pre-buffer media storage. The pre-buffering method includes recording an image capture segment of a variable bitrate input stream in a circular buffer. The circular buffer includes a number of recordable segments. The method includes recording a next image capture segment in a next adjacent recordable segment of the circular buffer if the next adjacent recordable segment of the predetermined number of recordable segments is available. The method includes overwriting an oldest recordable segment if the next adjacent recordable segment of the predetermined number of recordable segments is not available.

Abstract: Systems and methods are disclosed for testing image capture devices. For example, methods may include obtaining a test image from an image sensor; applying a low-pass filter to the test image to obtain a blurred image; determining an enhanced image based on a difference between the blurred image and the test image; comparing image portions of the enhanced image to a threshold to determine whether there is a blemish of the image sensor; and storing, transmitting, or displaying an indication of whether there is a blemish of the image sensor.
