A system for monitoring loading and unloading of goods or area transfers of goods. A terminal is positioned close to the point of passage of the goods. The goods being in containers, each container includes a barcode or a container carrier having a barcode. The terminal includes an image capturing device, configured to capture a photograph or film at the time when at least one container or container carrier passes in front of the terminal. A flash connected to the image capturing device triggers when a photograph or film is captured. A control unit includes a microcontroller driving the system and the database. A processing unit to process the photograph or film to identify the barcode captured in the photograph or film. A triggering unit to trigger the capture of a photograph or film based on at least detection of a container indicating passage in front of the terminal.

A barcode reader may include an image sensor array, an optic system, an image buffer, and a plurality of pre-processing circuits implemented in hardware.

The example device further includes one or more processors configured to: determine an ambient lighting condition based on at least a portion of at least one image frame captured as part of the image data; determine, based on the ambient lighting condition, whether to cause the imaging device to output a first feedback response or a second feedback response in response to a successful indicia decode; and responsive to receiving a successful indicia decode indication from the indicia decoder, cause the imaging device to output the first feedback response or the second feedback response.

A barcode reader may perform image processing functions to generate distinct image data records from the frame of image data of a barcode, select an image data record from the distinct image data records and decode the selected image data record. Each image data record may be generated by applying a distinct image processing function to the frame of image data. The barcode reader may capture multiple frames of image data in sequence based on image capture parameters. At least one of the multiple frames of image data may be captured with a distinct parameter value.
