Abstract: An image based code reader comprises an image sensor. The image sensor is configured to acquire an image of a code. Additionally, the image based code reader includes a lens configured to project an image scene including the code onto the image sensor, the lens comprising a variable optical power that controls a focus distance of the image based code reader. The image based code reader further includes a processor operatively coupled to the image sensor and the lens. The processor is configured to acquire the image of the code using only pixels located within a region of interest of the sensor, and a size of the region of interest is selected based on the focus distance of the reader.

Abstract: Systems and methods are provided for acquiring images of objects using an imaging device and a controllable mirror. The controllable mirror can be controlled to change a field of view for the imaging device, including so as to acquire images of different locations, of different parts of an object, or with different degrees of zoom.

Abstract: A computer-implemented method for scanning a side of an object to identify a region of interest is provided. The method can include determining, using one or more computing devices, a distance between a side of an object and an imaging device, determining, using the one or more computing devices, a scanning pattern for an imaging device that includes a controllable mirror, based on the distance between the side of the object and the imaging device, moving a controllable mirror according to the scanning pattern to acquire, using the one or more computing device and the imaging device, a plurality of images of the side of the object, and identifying, using the one or more computing devices, the region of interest based on the plurality of images.

Abstract: Systems and methods reduce temperature induced drift effects on a liquid lens used in a vision system. A feedback loop receives a temperature value from a temperature sensor, and based on the received temperature value, controls a power to the heating element based on a difference between the measured temperature of the liquid lens and a predetermined control temperature to maintain the temperature value within a predetermined control temperature range to reduce the effects of drift. A processor can also control a bias signal applied to the lens or a lens actuator to control temperature variations and the associated induced drift effects. An image sharpness can also be determined over a series of images, alone or in combination with controlling the temperature of the liquid lens, to adjust a focal distance of the lens.
