The second ISP processing unit 4 is data-connected to the second image pickup unit 2, and the second ISP processing unit 4 performs ISP processing based on an image picked up by the second image pickup unit 2.
The decoding unit 5 is respectively connected to the first ISP processing unit 3 and the second ISP processing unit 4, and the decoding unit 5 performs barcode decoding according to the image processed by the first ISP processing unit 3 and the image processed by the second ISP processing unit 4. If one of the images is decoded successfully, outputting the bar code; if both the two images can be successfully decoded, only one bar code is output; and if the two images cannot be decoded successfully, adjusting the distance between the bar code scanning device and the bar code to be scanned or adjusting the focal length of the first camera unit 1 and/or the second camera unit 2.
In practical use, the barcode scanning device capable of automatically adapting to different distances further comprises a display unit 6 for displaying barcode information, and the display unit 6 is in data connection with the decoding unit 5.
The utility model discloses a but bar code scanning device of different distances of automatic adaptation comes to acquire the scanning image simultaneously through the camera that uses two focuses differences to carry out ISP processing respectively to the image of acquireing, later decode via the decoder, show and improve bar code scanning device's DOF performance, but the code distance of sweeping of automatic adaptation difference simultaneously.
The present invention has been described in relation to the above embodiments, which are only examples for implementing the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. On the contrary, all changes and modifications which do not depart from the spirit and scope of the present invention are deemed to fall within the scope of the present invention.
