Abstract
The invention relates to an image display or shooting apparatus, in which several matrixes are joined edge to edge in accordance with the same plane, so as to form a large apparatus. The addressing circuits of the rows and columns of said matrixes are subdivided into addressing subcircuits and located in areas which are naturally inactive, or which are made deliberately inactive, i.e. areas having no active elements. In the case of shooting or photographing, in order to make the areas inactive, the active elements of certain pixels are destroyed in order to install in their place the addressing subcircuits, the information normally contained in the destroyed pixels being replaced by a reconstitution information obtained by averaging the information of adjacent intact pixels. The invention more particularly applies to the retinas of cameras used for the detection of non-focusable radiation and which are more particularly employed in radiology and nuclear imaging.
