Abstract: Imaging elements are provided. An imaging element has a wireless communication circuit adapted to detect a wireless communication signal and to generate a control signal; an illumination circuit having an illumination element, the illumination circuit being adapted so that the illumination element generates light at an intensity that is based upon the control signal and a body containing the wireless communication circuit and the light source, wherein the body occupies a space that is less than about five cubic millimeters. The imaging element can also incorporate radiation sensors and can provide wireless signals indicative of sampled radiation.
Abstract: A method for a chromatic adaptation transformation of images using temperature and tint space comprises the steps of: acquiring a red, green, blue (RGB) image using a camera (11); providing neutral RGB values for camera specific, and at least one of a selected highlight and shadow values, to produce a 3D lookup transformation table (21); calibrating the RGB image by applying the 3D lookup transformation table to produce a calibrated RGB image (22); calculating a Von Kries transform from specific temperature and tint values (14); and applying a chromatic adaptation to the calibrated RGB image using the Von Kries transform to produce a modified RGB image chromatically adapted (15), while maintaining neutral RGB values for highlight and shadow regions.
Abstract: A method for aligning the leading edge of printing plate (110) to an axially disposed slot (70) in a cylindrical surface (30) of an imaging drum (20) comprising at least one printing plate clamp (90) having a clamp surface (100) disposed parallel to the slot, the method comprising straightening (210) the leading edge against the clamp surface and positioning (220) the leading edge to protrude over the slot by rotating the imaging drum under the plate. The straightening comprises resting (200) the leading edge of the plate on the cylindrical surface of the imaging drum and rotating the imaging drum about its cylindrical axis (60) to contact with the clamp surface a point along the leading edge of the plate and to rotate the plate until its leading edge is in alignment with the clamp surface.
