Abstract
An imaging device and a method for capturing images under water and dynamically adjusting gain values for use in color correction. Minimum and maximum gain values as a function of depth are provided and a value of a parameter indicative of a point in a range between minimum and maximum gain values for a water depth is dynamically adjusted based on white balance analysis of the last captured image. A current gain value for a color of the color filter array is then determined based on the stored minimum and maximum gain values, the determined water depth, and the current parameter value and applied in the image/video pipeline to color correct the next image.
