摘要： Image signal processing includes generating an exposure compensated image based on a gain value applied to an exposure level of a first image and a gain value applied to an exposure level of a second image. The gain value may be progressively increased from an approximate center of the first image to an edge of the first image to a common exposure level. The gain value may be progressively decreased from an approximate center of the second image to an edge of the second image to the common exposure level. Gain values may be scaled on each color channel for a pixel based on a saturation level of the pixel.

摘要： An image capture device may capture visual content with an optical element having a field of view. The location of the image capture device, the direction of north with respect to the image capture device, and rotation of the image capture device may be used to determine location of celestial pole with respect to the field of view. A graphical user interface may be presented on an electronic display. The graphical user interface may indicate the location of the celestial pole within the field of view.
