Off-by-1?
« on: November 19, 2015, 02:25:28 AM »
In the ATIK 490 camera, the claim is that the pixel count is 3380 x 2704. Indeed that's what the spec on the Sony 814 sensor chip shows too.

Yet, when I run the camera in either of Artemis Capture or through the ASCOM driver to Maxim DL, the pixel counts show up as 3379 x 2703. So I have an odd x odd size with a Bayer matrix. How can that be? It looks like the 3379 x 2703 is an index, starting from zero - columns 0 - 3379 = 3380 columns, and rows 0 - 2703 = 2704 rows.

Or, is there something about the way the sensor is being read out that truly gives an odd number of rows and columns, and has a row and a column of truncated Bayer matrices?
