Claim Text:
1. A system for reading code symbols, comprising: a code-symbol-capturing subsystem for acquiring information about code symbols within the code-symbol-capturing subsystem's field of view, the code-symbol-capturing subsystem comprising a receiving sensor for receiving reflected signals of electromagnetic radiation; an object-detection subsystem for detecting the presence of an object within the code-symbol-capturing subsystem's field of view, the object-detection subsystem comprising an electromagnetic radiation source for emitting electromagnetic radiation toward an object within the code-symbol-capturing subsystem's field of view; and a calibration processor for adjusting the electromagnetic radiation source's emission power in response to the reception power of the reflected signals of electromagnetic radiation received by the receiving sensor; wherein the code-symbol-capturing subsystem is configured to acquire information about code symbols within the code-symbol-capturing subsystem's field of view if the reception power of the reflected signals of electromagnetic radiation emitted by the object-detection subsystem and received by the receiving sensor is substantially equal to a predetermined target reception power.
