Autofocus 1D and 2D Code Reader

SR-1000 series

AUTOMATIC PARAMETERS

OPTIMUM SETTING OF EXPOSURE TIME, FILTERS AND MORE

The code reader automatically optimises the exposure time, image processing filter and other parameters according to the target and mounting distance.

CLEAR IMAGE CAPTURE
CORRECTION ITEMS AND EXAMPLES OF AFFECTED CODES

CAPTURE BRIGHTNESS CORRECTION

Automatically configures various combinations of exposure time, dynamic range and gain in order to achieve the optimal brightness.

CONTRAST THRESHOLD CORRECTION

Automatically corrects black/white thresholds and optimises the contrast between code and background.

FILTER CORRECTION

Automatically selects the best filter and filtering intensity to correct the captured image.

GEOMETRIC CORRECTION

Corrects distorted codes, such as those on cylinders and other round surfaces or when the reader is mounted at an angle.

IMAGE REDUCTION & CORRECTION

Reducing the image size may reduce background noise or missing spaces. Defects from background noise, dirt or scratches may appear insignificant after the image size reduction, hence causing them to be neglected.

HIGH- LEVEL DECODING

CONTRAST ALGORITHM FOR LOCAL CONCENTRATION (CALC)

Our contrast algorithm for local concentrations divides a code into smaller pieces to perform binary processing using thresholds specified for each division. This enables accurate black/white classification without being affected by uneven print density.
