Abstract
A method and a stereoscopic apparatus configured to determine an exposure time period for capturing images. The apparatus comprises at least one image capturing device for capturing pairs of images; a processor configured to: calculate a texture-signal-to-noise ratio (TSNR) metric based on information derived from a pair of captured images; calculate an image saturation metric based on that pair of captured images; calculate a value for an exposure duration that will be implemented by the at least one image capturing device when another pair of images are captured; provide the value of the calculated exposure time period to each at least one image capturing device; and wherein the at least one image capturing device is configured to capture at least one image of the target while implementing each the respective calculated value of the exposure time period provided to the corresponding one of the at least one image capturing device.
