US Patent 9454689 Rolling shutter bar code imaging

Methods, devices, and systems for rolling shutter bar code imaging are described herein. One method includes initiating the imaging of a bar code by initiating a sequence of procedures to accumulate a charge in a first row of pixels as they are exposed to light thereby capturing data to create a first row of the image of the bar code at a first time, initiating the sequence of procedures to accumulate a charge in a subsequent row of pixels as they are exposed to light thereby capturing data to create a subsequent row of the image of the bar code at a second time, actuating a light source to illuminate the bar code at multiple specific times during a pre-determined timing sequence, and de-blurring the image data for each row based on the specific times during the pre-determined timing sequence that the light source was actuated.
