Apogee CCD camera,

[Ty05]

Hey Folks,

My aim is to find the Characteristics of a CCD Camera.
Some of them have been achieved, Ive good control of the temperature and getting an image is grand. My huge problem exists in identifying the gain (taken from a graph - then the slope = gain) from a smaller image, maybe 1/20 the size of my large image.

Even if I set the columns and rows of interest to a certain size it always seems to go back to the original larger image's data. In this case 511*512 size, I need maybe 40*40, so my results are terrible.

Any assistance would be smashing,
My head is sorta on the block with this one.
Thanx
I apologise for my programming, im still learning.

Hi,
I can see where you take the image data and convert it over to a 2D array of double precision numbers, however I can't see where you take the subset?
I think the confusion is the bit where you take the skipC and skipR and create a 2D array which is only for type information and will not limit the data. I've attached a simple piece of code in LabVIEW 7.1 to demonstrate this.

Can you provide a walkthrough on this a little or simplify the code?


Thanks

Hi there,

I have an apogee camera and a labview program that company sent with that.

Right now I can take an image but I need to take a video, I am not good in Labview programming, I used while loop to be able record a video, but it does not work.

I attached the Labview code, if you know the solution please let me know what should I do?

thanks, Vahide
