Barcode-reading application that is designed for a general-purpose computing device and that includes a motion detection module

A general-purpose computing device that is configured for barcode reading, comprising:

• a camera that is configured to capture image frames, the camera having a field of view;
• a proximity sensor;
• a processor;
• memory that is communicatively coupled to the processor;
• and
• a barcode reading application stored in the memory, the barcode reading application being operable in a motion detection state, a decoding state, and an inactive state, the barcode reading application comprising:
• a motion detection module that is executable by the processor to process captured image frames for performing motion detection, wherein the motion detection module does not process captured image frames unless the proximity sensor has detected an object within a threshold distance of the general-purpose computing device, and wherein the motion detection module processes captured image frames at a motion detection processing frequency when the barcode reading application operates in the motion detection state;
• and
• a decoding module that is executable by the processor to implement one or more barcode decoding algorithms, wherein the decoding module does not process captured image frames unless the motion detection module has detected motion in the field of view of the camera, wherein the decoding module processes captured image frames at a decoding processing frequency when the barcode reading application operates in the decoding state, and wherein the motion detection processing frequency is less than the decoding processing frequency;
• wherein neither the motion detection module nor the decoding module processes captured image frames when the barcode reading application is in the inactive state;
• wherein the motion detection module processes captured image frames and the decoding module does not process captured image frames when the barcode reading application is in the motion detection state;
• and
• wherein the decoding module processes captured image frames and the motion detection module does not process captured image frames when the barcode reading application is in the decoding state.
