Text, 1D and 2D code reading

The VX6854LC camera module features a Supermacro mode dedicated to business card

and text reading as well as barcode and 2D QR code reading using a monochrome image.

Figure 29. Examples of barcode and QR code

Note:

The above performances were achieved on VX6854LC in Supermacro mode through ST’s

image processing pipe and with standard mobile phone application QR decoder software.

Refer to the “EDoF application note” for recommendations on Host processing pipe tuning

for QR/Barcode reading.
