save an unsigned24-bit array into three image (R, G, and B channel)

[Larry Liu]

Hi all.

I acquired one image from my color camera. The data is in a 2D array of unsigned 24-bit data.

I want to get the R, G, and B data (corresponding to the 16-23, 8-15, 0-7 bit) in to three different images.

Is there LabVIEW function can perform this job?

Thanks a lot...

Have you tried the Color to RGB VI? Or, you can always use the Split Number node.

In Labview you have 8,16,and 32 bits data types but non 24 bit. So I guess your 2d array is U32 data type. You can mask any color using logical and functions in the Boolean function palette. if you want to only keep the information in bit 16 to 23 you "and" every number in the array with 0x0F00, bit 8 to 15 you "and" with 0x00F0, and so on.

The Color to RGB VI will do that for him. That VI is password protected but the RGB to Color VI isn't and should give you an idea of how the former is implemented (assuming it's just inverted logic, which I'm sure it is). And, yes I didn't mention that they isn't a 24 bit data type, but I was assuming he would've figured that out 🙂

thanks a lot for the help, guys,

I used color to rgb to solve this issue.
