A point of sale device (20) is provided comprising a base unit (22) and a cover unit (34) connected to one another by a hinge mechanism (38). The base unit has a front surface (24) and an exterior casing (25) which define an interior volume. Transaction appliances, for example, a card reader (26), receivables storage drawer (28), a currency storage drawer (30), and a bar code scanner (32), are mounted in the interior volume and accessible from the front surface of the base unit. The cover unit includes a display screen (36) mounted on one side. The cover unit can be moved between a closed configuration and an open configuration. In the closed configuration, the cover unit is positioned with the display screen facing and directly in front of the front surface of the base unit such that the display screen is not visible and access to the transaction appliances in the base unit is blocked by the cover unit. In the open configuration, the user can access the display screen and the transaction appliances. A control unit (40) and input unit are provided to facilitate communications between the user and the POS device to facilitate the performance of desired transactions.

In a video camera, "shading ears" resulting from charge build-up beyond the ends of the scan lines of the normally scanned area of a camera tube target are eliminated by applying a voltage pulse to a lens electrode of the camera tube, the timing, amplitude, duration, and shape of the pulse being predetermined to extend the scan lines, and also to de-focus the electron beam.

Horizontal and vertical registration errors in a color television camera are automatically corrected on-air by detecting registration errors in live scenes, associating each error with a preselected region of the raster in which it was detected, separately accumulating errors for each region, periodically analyzing the distribution, magnitudes and signs of the accumulated errors, and the past history of registration errors to determine the type of registration error present, and generating a correction signal to correct the registration error. Vertical registration is effected using vertical video signals derived by sampling the component color video signals from the camera along vertical lines of the raster. A microprocessor-controlled automatic registration system is disclosed.
