Abstract: The apparatus according to the present invention provides an alignment mask disposed in the CRT plane, and the CRT parameters are measured by observation of the light collected through the alignment mask from the CRT and processing the corresponding light intensity signals. The light sensing device provides a signal which is processed typically by a microprocessor controlled geometry engine to derive a set of correction data which is based on a prototype array of initialized data values. The parameters corrected by the apparatus and method according to the present invention include x and y position, focus and relative picture intensity over the surface of the screen (vignette). The above listed parameters are used alone and in combination to provide image centering, image scaling and pincushion correction, correction for non-orthogonality between the x and y deflection coils, image rotation and correction for nonlinear second and third order effects. The set of data can also be deliberately distorted to provide image precompensation such as keystone (trapezoid) and spherical corrections as well as vignette compensation such that, when the final image is projected or displayed, a true (nondistorted) image results.

Abstract: Registration of an image with respect to a recording medium in a film recorder or the like is provided by first roughly positioning the recording medium in a support. A beam is then scanned across an unused portion of the recording medium until it impinges a fixed reference mark such as a sprocket hole edge. The coordinates of the beam are determined at the reference mark, and a registration signal is computed therefrom. The beam is then scanned across the recording medium in response to the registration signal to record information in registered relation to the reference mark. An intensity profile of the beam is calculated as it passes over an edge of the recording medium. The focus of the beam is then adjusted according to the intensity profile. Adjustment of both beam focus and lens focus is provided.
