While I read the IMS camera spec of DFK 41AU02.AS (color, 1280x960, USB version), I found it states that the CCD chip (Sony ICX205AK) is 1/2" type which I thought theoretically doubling the FOV of DFK ...

Hi,
The mono series 21 is a 1/4-inch CCD (4.5 mm diagonal, 4.60 x 3.95 mm) and each pixel is 5.6 x 5.6 micron.
The 31 series is 1/3-inch CCD (6 mm diagonal, 5.80 x 4.92 mm) with pixel size of 4.65 x 4.65 micron.
The 41 series is 1/2-inch CCD (8 mm diagonal, 7.60 x 6.20 mm) with 4.65 x 4.65 micron pixels.
FOV calculations should be based on the chip size, not pixel size.
Please refer to attached data sheet.
