Leonard Reiffel - Chicago IL 60614

International Classification:

G06K 710

US Classification:

23546241, 23546211, 23546224

Abstract:

An imager ( ) has a locate mode ( ) which detects light ( A, B) having a preset light property from at least one locator ( ) in the imager field of view ( ); and has a react mode which is caused by the locate mode to select light from a code region ( A, B, B) over light not from the code region ( ) and which outputs a signal ( ) representing code in the code region.

Inventors:

Leonard Reiffel - Chicago IL, US

International Classification:

G09G 5/08

US Classification:

345157, 345156, 715856

Abstract:
