8bit to 10bit

[学生1号]

Used after the image acquisition interface usb how to store, want to store 10-bit (analog acquisition for the 8-bit), I need a procedure, thank you!

Hi,

could you give more details to your question?

You can save your data using a different data format, like using U16 instead of U8. This way you get the space for those extra 2 bits...

My experiment is that the use of USB interface camera, through image acquisition card collecting optical images, in implementation on computer image storage, image format to the 10.I use  LV8.0, 8.2 . Look forward to your reply.Thank you.

Hi,

it is stil not clear to me what you relly need...

You receive 8bit image data, but want to store in 10 bit resolution? AFAIK IMAQ gives opportunity to save 16bit TIFF images, but I don't have IMAQ installed to check it. 

This forum is not intended to give ready-to-use solutions, but to provide help. Please post what you have programmed so far...

In fact, my most important necessary  are  stored  images in a  process, because I am a beginner, not a lot of things are understanded , but I said that I need to do the whole course of the experiment (the experiment used both Analog interface for image acquisition 8 digital image format, and now want to adopt USB interface are collected and stored for the implementation of more than 10 picture format). Give me some examples or process to reference to,. Thank you always help me to answer questions, thank you!

Hi,

look for the image write functions of the NI Vision module. They should provide options to save pictures with more than 8bit color resolution. As I don't have this module installed I can't check them quickly (and I also don't find them in a hurry on the NI website)...

In Fact, the IMAQ driver for USB camera can only support standard picutre format,suc as "BMP, JPEG,TIFF,PNG".

IF you want to change the file format of the picture ,you have to use the FILE IO operation.such as FILE read and write.

What's more, The LabVIEW can only support U8 U16 U32 and double format, it can not directly support 10bit

format,you may choose to use U16 to storage the 10bit data.
