Abstract: A method and apparatus for an alternative representation of information that is displayable onto a user interface display screen. The information can be displayed as at least one portion of a data range, such as data representing characteristics of one or more signals over time, while the alternative representation can be displayed in accordance with a set of one or more user selectable magnification attributes associated with the portions of the data range and associated with one or more axis directions relative to a plane of the display screen.

Abstract: A colorimeter capable of calibrating color monitors, whether having cathode ray tube or liquid crystal (LCD) displays, is provided by a photometric array of photodetector and optical filter pairs. The filters include long-pass, edge filters which cover overlapping regions at the upper end of the visible spectrum and a filter which covers the entire visible spectrum. The outputs of the photodetectors are digitally synthesized to provide a response which mimics the response established by the Commission Internationale de 1′Eclairage (CIE) xyz (bar) functions almost perfectly. The response which is mimicked may be represented by the CIE color matching functions. The pairs and the associated components are mounted on a printed circuit board captured in a clamshell housing and having an array of apertures which define angularly constrained fields of view of a surface from which the light, to be colormetrically analyzed, emanates.
