Abstract: A method for processing data, in particular an image representative of an observation zone in which is situated an object arranged with respect to a reference plane.

Abstract: This image processing system comprises: a device (PRJ, SI1) for projecting a first light beam (FL1) to form a first image (I1) on a screen (ECR) on which a second light beam (FL2) coming from an observation area (ZO) forms a second image (I2) and a device (CAM, SI1) for acquiring a third image (I3) formed on the screen (ECR) and corresponding to the superimposition of the second image (I2) and at least a portion (I1?) of the first image (I1). This system further comprises control means (CTR) for: obtaining a first signal (S1) representing the portion (I1?) of the first image (I1), obtaining a second signal (S2) representing the third image (I3), and calculating a third signal (S3) by subtracting at least part of the first signal (S1) from the second signal (S2) to form an image (I2?) representing the observation area (ZO).

Abstract: The invention relates to a device (1) for a videoconference communication between a local user (5) and at least one remote user (6), which reduces the eye deflection and provides a better eye contact between the local user and the remote user. The device includes a screen (4) capable of restoring, for the local user, an image of the remote user, and an image sensor (3) capable of sensing an image of the local user for the remote user. It further comprises a light source (2) arranged, relative to the image sensor, so as to lighten the eyes of the local user watching the screen during a communication with the remote user, so that the image sensor can detect an image of the local user including a reflection of the light source on a portion at least of each eye of the local user, including the pupil. The device further includes communication means (7) capable of transmitting the detected image to the remote user (6).

Abstract: A method for making uniform the colorimetric rendering of a display surface including several adjacent display screens (10a, 10b), comprising for each pair of adjacent screens (10a, 10b) steps of: periodically sampling (21) by a calculation device (5) image data in two corresponding screen (10a, 10b) areas (13a, 13b) in the pair of adjacent screens, analyzing (22, 23, 24) by the calculation device (5) image data sampled in each period to determine a difference in calorimetric rendering between the two screen areas, determining by a correction device (6) connected to the calculation device a process to be applied to the video stream to one of the two video systems controlling the two screens in the pair of adjacent screens, by applying a predetermined correction law to the difference in calorimetric rendering, and applying (26) by the correction device the process to said video system, in order to make the colorimetric rendering of the display surface uniform.

Abstract: An optical system comprises a first image capture device for capturing an image of an observation area, a first display device, a semi-reflecting plate, a concave mirror disposed facing the first display device, and a second display device for displaying a background image. A light beam is scattered by the first display device through the semi-reflecting plate and then reflected by the mirror and the semi-reflecting plate in order to display an aerial image between the semi-reflecting plate and the observation area. A projector projects a light beam toward one of the display devices. The first image capture device is adapted to capture the image of the observation area via said one display device. A alternating control device alternates capture of an image of the observation area by the first image capture device and projection of the light beam projected by the projector.

Abstract: For segmenting in real time a first digital image of an observation area captured by an image capture device and transmitted to a data processing device, a second digital image each pixel of which is associated with a magnitude such as a distance relative to a point of the observation area is captured and transmitted by another image capture device to the data processing device. An image merging module establishes a correspondence between pixels of the first image and pixels of the second image and selects the pixels of the first image corresponding to the associated pixels of the second image as a function of magnitudes associated with the pixels of the second image. Only the selected pixels of the first image are displayed to form a segmented image.
