Embodiment Construction

[0036] first reference Figure 1A , which is a diagram depicting various components of a polychromatic illumination scanner according to an example embodiment. It is to be noted, however, that the configuration shown is shown schematically in a greatly simplified form, showing only components relevant for understanding the illustrated embodiment.

[0037] Figure 1A Indicates the vertical tower assembly, which contains the tower cabinet, camera, lighting source, LED indicators, mirrors, buttons, cord extensions, and speakers.

[0038] The vertical tower assembly scanner also includes a controller (processor— Figure 1A not shown in (below Figure 1C and image 3 controller depicted in )).

[0039] The novel camera illumination source is a combination of independently controlled white LEDs and a combination of independently controlled colored LEDs. The controller selectively activates white and colored LEDs to create a flashing effect.

[0040] In an embodiment, the control...

Abstract

A scanner camera is presented with a controller that selectively illuminates white and / or colored light sources, during each particular color illumination of an object being imaged, the camera captures a monochrome image of that particular color illuminated object. One or more of the images are processed by the controller to obtain information about the object being imaged.

Description

technical field [0001] The present invention relates to controlled and multicolor scanner illumination. Background technique [0002] Point-of-sale (POS) devices typically include a variety of integrated devices such as scanners, scales, integrated scanners with scales, card readers with on-screen signature capabilities, and similar devices. [0003] An advantage of image scanners over laser scanners is their ability to read two-dimensional (2D) symbols and actually better detect some poor quality one-dimensional (1D) labels. However, until now, image scanners are still relatively more expensive than laser scanners. This is largely due to the fact that camera scanners require several (more than one) cameras to see several sides of the scanned object, which is a requirement for dual mirror scanning. [0004] However, recent watermarking techniques utilizing wrappers have made the need for multiple cameras less necessary. This is the case because the barcode and other infor...
