Abstract: A device and method for determining exposure settings in a camera is disclosed. The method comprises capturing an image frame using an image sensor, the exposure of the capturing is based on an initial exposure value setting, determining a temporary exposure value by finding an exposure value that results in a substantially optimum value when applied to a total cost calculation, calculating a saturated pixels cost related to the saturated pixels for the captured image at the temporary exposure value, determining a next exposure value by finding a decrease in exposure value, in relation to the temporary exposure value, for which decrease a change in total cost for non-saturated pixels, in relation to the total cost for non-saturated pixels at the temporary exposure value, is substantially equal to the saturated pixel cost calculated at the temporary exposure value, using this determined next exposure value for capturing a new image frame.

The method may include sending the search query to the neighboring service registry and receiving, from the neighboring service registry, a second list of services, registered with the neighboring service registry, that satisfy the search query. The method may include returning, to the client, the first list of services and the second list of services that satisfy the search query.

Abstract: A method for controlling exposure of a camera is disclosed. The method comprises calculating a darkness level and a saturation level with respect to a first image in a video sequence. If the saturation level exceeds a first limit, a target value for a mean intensity value of pixels in images captured by the camera is decreased by an amount which is an increasing function of the darkness level. The decreased target value is used to control the exposure of the camera for images subsequent to the first image in the video sequence, such that the mean intensity value of pixels in the subsequent images approaches the decreased target value.
