Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of determining one or more optical parameters of a lens of eyeglasses. For example, a product may include one or more tangible computer-readable non-transitory storage media including computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to process at least one captured image of at least one reflection of a flash on a lens of eyeglasses; and determine one or more optical parameters of the lens based at least on the at least one captured image.

Abstract: A method and apparatus are provided for assessing the operation of a col or printing system (10) by measuring color plane mis-registration. The printing system (10) is caused to print a multi-sheet test job (26) with corresponding test points on each sheet distributed vertically and horizontally over the sheet. The test points comprise test markings for determining horizontal and vertical color plane mis-registration values. These test markings are measured by an imaging subsystem (30) to determine horizontal and vertical color plane mis-registration values (31) for the printing colors. The mis-registration values are then analyzed (33, 36) by a processing subsystem (32) to derive a plurality of mis-registration parameters that provide different respective views of mis-registration behaviour across the test sheets. An output is provided based on the mis-registration parameters.
