摘要： 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).

摘要： 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.
