Abstract: The invention concerns a calibration device including a sound recording system including microphones coupled to an audio signal processing device, the calibration device further including an enclosure at least partly containing the processing device, a sound generator coupled to the processing device, and a support of the microphones capable of maintaining the microphones at the same distance from the sound generator.

Abstract: A method and device for monitoring phase shifting between stereoscopic cameras. The device for monitoring phase shifting between the images from the stereoscopic cameras includes: a circuit (100) for characterizing the phase shift, which implements the method and is connected to the output terminals of the stereoscopic cameras (G, D); and a monitor (106) for displaying video images, including resources (63) for displaying the images (61, 62) one on top of the other, the image being generated by the cameras and resources (90, 94) for displaying the values (H, V) characterizing the phase shift in relation with the images.

Abstract: The invention relates to a viewing screen device, including a casing (8, 18), itself including a first portion (18), a so-called front portion, and a second portion (8), a so-called rear portion, the front portion including a rear face (182) and the rear portion including a front face (82, 82?), a portion of this front face forming in the closed position a gap (90) internal to the device, delimited on one of its sides by a surface (80), a so-called connecting surface, including at least one connection (101, 102, 103) of a cable, means (830, 831) for closing or opening the casing, by moving said rear portion (8) away from or closer to said front portion (18), while maintaining both of these portions attached to each other, a side portion (83) of the casing further including at least one opening (101?, 102?, 103?) for letting through at least one cable (14, 14?, 14?) intended to be connected to one of the connections (101, 102, 103).
