A display controller controls the display luminance of a display device in dependence on the ambient light level. It also controls the amount of the dynamic range compression of the input display data, the amount of compression depending on the ambient light level. The dynamic range of the display data is compressed to match the dynamic range of the display device. The dynamic range of the display device depends on the ambient light level and the display luminance.

A method for analyzing a video stream is provided. The method determines a set of two or more frames containing an object, and generates an object record describing time evolution of at least one characteristic of the object. An apparatus comprising a processor and a memory to perform this method is also provided.

A method to analyze an image and determine whether to output image data associated with an area of the image is provided. An object detection algorithm using training image data to detect an object based at least in part on a similarity of appearance of image data to data derived from the training image data is provided. Weakly detected objects are classified based on characteristics associated with the weakly detected object and may be added to the training image dataset for use in further training of the object detection algorithm. The object detection algorithm is trained with a revised dataset, the revised dataset being updated with data generated by the object detection algorithm.

An image sensor provides a first image with a first exposure and a second image with a second exposure. An exposure controller sets the first exposure in dependence on pixel intensities of at least one of the images. It sets the second exposure in dependence on a factor and the first exposure. The factor is determined in dependence on pixel intensities of at least one of the images.
