Abstract: A projection subsystem includes a projector for projecting an image on a projection surface and a safety feature for tuning the projector when presence of a human is detected in front of the projection surface. This safety feature includes: —an apparatus for computing a depth view corresponding to at least a portion of the projection surface, —a camera for acquiring a captured image, —a computing circuit for detecting an object between the projector and the projection surface from this depth view and determining that the object is a human from the captured image, and a control circuit for tuning the projector accordingly.

Abstract: It is proposed a method for the projection of a sequence of images onto a projection surface by a handheld device having an embedded projector, said method comprising, for an input image to be projected of said sequence of images: a step of evaluation wherein a spatial position variation is evaluated with respect to a reference spatial position of said handheld device; and said spatial position variation is defined by a spatial orientation variation and a spatial vector variation; said spatial vector variation being determined by 3 independent coordinates; and at least one of said 3 independent coordinates is provided by a stereoscopic sensor; a step of compensation wherein a compensated image is generated from said input image to be projected depending on said spatial position variation; and a step of projecting onto said projection surface said compensated image.
