An event-based sensor having a sensing part that produces events asynchronously. The output signal includes information relating to at least some of the produced events. The method comprises: estimating a rate of production of events by the sensing part; while the estimated rate is less than a threshold, transmitting the signal having a variable rate; and when the estimated rate is above the threshold, transmitting the signal including information relating to only some of the produced events, such that a rate of events for which information is included in the signal remains within the threshold.

Method for outputting a signal from an event-based sensor, and event-based sensor using such method

A method and device for producing at least one self-portrait image using a mobile device having a display and an image-capturing device following at least one capture trigger of the image-capturing device. A position of the image-capturing device in relation to the orientation of the display is detected. The brightness of the display is increased and a predetermined imaged is displayed on the display. At least one self-portrait image is captured.

Method and device for producing at least one self-portrait image

A picture taking device includes at least three camera modules, each having a sensor of resolution equal to or higher than thirteen megapixels. A diagonal of the photosensitive surface of the sensor of between 5 mm and 7 mm. An objective lens opening at minimum to f/2.0 for at least one focal length value. The device has a power supply and, a rigid connector to connect it to a mobile phone or tablet comprising a screen, and communicates images and/or commands with the mobile phone or tablet. The device also includes a digital processor to reduce noise while preserving the textures in at least one image captured by one of the sensors.

The present invention is directed to a video communication system capable of providing adaptive compression of video image data. In particular, data regarding the range of possible motions and the respective probabilities of such motion within a scene are collected, and a compression algorithm appropriate to motions having high associated probabilities selected. In response to a change in the motions and associated probabilities within a scene, a new compression algorithm can be selected. The bit rate of data transmitted by a system in accordance with an embodiment of the present invention will therefore vary, depending on the content of an imaged scene and based on the compression algorithm applied in order to compress image data while maintaining appropriate detail.
