摘要： A method (200) of activating a display screen of a device, includes establishing (201) a connection with each of one or more candidate display screens (119). A direction of gaze (121) of an eye of a user (117) is tracked (203), and a display screen (119) is selected (207) from the one or more candidate display screens when (205) the display screen (119) is in the direction of gaze (121) of the eye of the user (117). A confirmation code (305) is caused (209) to be displayed on the selected display screen and an image of the selected display screen is obtained. The selected display screen is activated (215) in response to detecting (213) the confirmation code (305) in the updated image of the selected display screen.

摘要： A method of detecting objects in a video comprises, for each image in the video, determining (78) a degree of correlation between the image and at least one preceding image in a sequence of images; and obtaining (80) a first measure of energy consumption required for performing an object detection process on the image, obtaining a second measure of energy consumption required for performing an object tracking process for tracking at least one object from a previous image, and comparing (82b) the first and second measures of energy. The object detection process (84) is performed on the image if either said degree of correlation is below a threshold level or said first measure of energy is lower than the second measure of energy, and otherwise the object tracking process (86) is performed on the image.

摘要： A combined camera and VLC circuit (5) is disclosed. The circuit (5) comprises an image sensor (10) comprising an array of pixel sensors (70), wherein each pixel sensor has an associated color (B, Gl-2, Rl-4) and is configured to generate an analog value representative of an amount of light that the pixel sensor (70) has been exposed to. Furthermore, the circuit (5) comprises a readout circuit (20) connected to the image sensor (10) and configured to generate analog output samples representative of the analog values generated by the pixel sensors (70). In a first mode of operation, the readout circuit (10) is configured to, for each pixel sensor (70), generate an individual analog output sample representative of the analog value generated by that pixel sensor (70). In a second mode of operation, the readout circuit (10) is configured to, for each group of a plurality of groups of multiple pixel sensors (70), generate a combined analog output sample representative of a combination of the analog values generated by the pixel sensors (70) in that group. Each group of pixel sensors (70) has a related color and consists of all pixel sensors (70) having the related color as its associated color.

摘要： There is provided an image acquisition controller for acquiring an adapted image. The image acquisition controller comprises an interface towards a first image sensor, the first image sensor being arranged to acquire an image, and an interface towards a gaze tracking unit, the gaze tracking unit comprising a second image sensor for registering a gaze position on a scene associated with the image acquired by the first image sensor. The image acquisition controller is arranged to periodically receive information over the interface towards the gaze tracking unit about at least a position on the scene associated with the image provided from the first image sensor where the scene represents a larger part of an image registered by the first image sensor than intended to be acquired as the adapted image. The image acquisition controller is arranged to provide information over the interface towards the first image sensor about a position on the first image sensor, a size of a sensor area associated with the position on the first image sensor and a frame rate for image acquisition within said area. The image acquisition controller is arranged to receive image data over the interface towards the first image sensor wherein the image data at least comprises image data with the size, the position on the first image sensor, and the frame rate for image acquisition within said area such that the received image data is stored. An image acquisition system or device comprising the controller, a communication device with corresponding image acquisition capabilities, a method of image acquisition, and a computer program for implementing the method are also disclosed.
