## Abstract

The present application provides an optical information collector and a method thereof. The optical information collector includes an image sensor, configured to collect image data of optical information; a decoding unit, configured to decode the image data based on a preset decoding algorithm; a central processor, configured to control the image sensor to collect the image data and control the decoding unit to decode the image data upon triggering. Once triggered, the central processor issues an instruction to discard N frames of image data in a specific frame number, where the N frames of image data in a specific frame number is image data that was previously collected and remaining in the optical information collector upon triggering, which can prevent residual image data from being decoded and outputted, causing a decoding error, thereby improving a decoding efficiency.
