Abstract: An imaging device has a plurality of predefined regions of interest. The predefined regions of interest may be selected or deselected. Image data from selected regions of interest is transmitted to a host. In some embodiments the regions of interest comprise tiles. A set of selected tiles may be identified by a bit vector. An example application provides a digital camera configured to provide predefined regions of interest. The camera may be configured to permit a host to select or deselect the regions of interest.

Abstract: A camera has a strobe output. When the camera acquires a sequence of images, a strobe pattern control determines for each image whether or not to apply a strobe signal to the strobe output according to a predetermined pattern. The predetermined pattern and the length of the sequence can be user defined by way of a suitable software interface, for example. The strobe output may be used to control a device such as a flash unit, a sound recorder or the like.

Abstract: A system for measuring dimensions of cuboid objects may be used to measure dimensions of boxes travelling on a conveyor. The system has a pair of digital cameras which obtain images of one or more lines projected by a projector on upper surfaces of the objects. The height of the upper surfaces can be determined by triangulation. Lengths and widths of the upper surfaces are measured by locating endpoints of the projected lines and fitting rectangles to the located endpoints. The system does not require rigid mounting of the projector relative to the cameras. A third camera may be used to determine speed and direction of the conveyor motion.
