  • Code reading device and method with variable light signal storage time
    Patent number: 6010070
    Abstract: In a method for optically reading a label carrying information recorded thereon using a charge coupled device, a storage time of an incident light signal in the charge coupled device is changed to effect proper reading. The light signal storage time is changed until the charge coupled device reads the code, and then the light signal storage time is fixed. Thereby, a code is read without failure by effectively preventing reading error or failure due to an excessively light or dark environment, or varying distance between the code and code reader. Thus, a code is correctly read regardless of whether the code is close or far.
