Title: Data read system
Inventor: NELSON DAVID J
IPC: G06T1/00
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a data read system for reading an invisible image, in which a zero-th order beam or plural zero-th order beams do not exist, by carrying a visible primary image and a secondary image overlapped on that visible image through a medium and modulating the frequency band of invisible electromagnetic radiation where the secondary image is transparent in respect to visible light. SOLUTION: A data reader 10 is used for a system 18 provided with a medium 20 for carrying a visible primary image 22 and a secondary image 24 overlapped on the primary image 22. The secondary image 24 is invisible, namely, transparent to the visible light but a detector modulates the frequency band of invisible electromagnetic radiation having photosensitivity. A visible reference 26 is aligned with the secondary image 24 but deviated. The frequency area or plural frequency areas of invisible light modulated by the secondary image 24 depend on the characteristics of a material to be used for the secondary image 24. Either infrared rays or ultraviolet radiation or the both can be used while depending on the material. Thus, the system can be used for both visible and invisible bar codes.

Abstract: PURPOSE:To improve the picture sink by providing a waveform shaping means applying waveform shaping to an output of a signal converting means to form a pulse signal, clamping the said pulse signal to a prescribed potential to add it to a control signal of an AGC circuit. CONSTITUTION:An optical signal is fed to an image pickup element 2 via a lens group 1, converted into an electric signal and amplified by an amplifier 3. An output of the amplifier 3 is sliced by a limiter circuit 13 as a waveform shaping means to form a pulse signal. The pulse signal is fed to a clamp circuit 14 and clamped to a prescribed potential, e.g., in the vicinity of '0'V, added to a control signal of an AGC circuit 7 as the control signal and the level of the control signal is decreased for a period of the pulse signal only substantially to improve the gain of the circuit 7. Thus, even when a bright object is given to any part of a pattern, the picture sink is improved.
