Patent ID: 7413125

Claim:
An optoelectronic device for acquiring machine-readable symbols, comprising: a sensor array comprising a plurality of light sensing elements, each respective light sensing element of the plurality of light sensing elements producing a respective signal representative of a quantity of light incident on the respective light sensing element; and a scanning control circuit coupled to selectively sample the respective signals from the light sensing elements of the sensor array at a respective resolution of the sensor array defined by a respective number of light sensing elements of the sensor array that are sampled together when the respective number is greater than one during a respective sampling pass and operable to change the respective resolution of the sensor array between at least a first resolution defined by a first number of light sensing elements of the sensor array that are sampled together when the first number is greater than one during at least a first sampling pass and a second resolution defined by a second number of light sensing elements of the sensor array that are sampled together when the second number is greater than one during at least a second sampling pass, the second sampling pass following the first sampling pass, and the second number of light sensing elements is different from the first number of light sensing elements.
