The Bexel Irina was developed using the standard photo size of 640X480. Many individuals believe that the higher megapixel size iriscopes are better, although this is a myth. The lens of an iriscope is far more important! To learn why the higher megapixel is a myth, please review this following article: The Megapixel Myth
You may be able to use higher megapixel than 640X480 with Bexel Irina, although images must be in multiples of 640X480, such as 1280X960, 2560X1920. If you find that the Bexel system is crashing when importing your iris photos, it is then recommended to resize your images and re-import them into Bexel Irina. To resize your images quickly, you can download a free program that can resize your images quickly: Download Image Resizer
Another very important image factor is that your eye images must be in Bitmap format (BMP) to import into the Bexel Irina. Bitmap is an uncompressed image format and offers much more data information that other graphic image formats. For example, JPG is compressed graphic image and is 1/10 the size of BMP. The Bexel Irina requires uncompressed images for more accurate bio-metric detection of the pupil and collarette. If you need to convert JPG or other graphic image formats to BMP, please download and install this free image converter: XNConvert
XnConvert is the Swiss Army knife of image converters. With XnView, you can convert any of around 500 image formats to your choice of around 80 others. If you have a rare image format that you can’t open, XnView can probably convert it.
XnView also supports batch conversion, folder imports, filters, resizing, and several other advanced options.
