Sumix SMX Camera for Python

API in Python that wraps Sumix SMX M8X C API.

Requires:

Note:

  • Best to run in native Windows instead of virtual machine
  • Most people rightly use 64-bit Python. However, here you will need a 32-bit Python install; it doesn't take much hard drive space.

Installation

  1. Download Sumix SMX M8X C API

  2. Extract ZIP file, run EXE as Administrator

  3. install under C:/Sumix/, NOT C:/Program Files (x86)/Sumix

  4. plug in your Sumix SMX-M8X(C) camera into a USB 2.0 port

  5. be sure the camera is working properly with Sumix's demo program, get familiar with setting exposure, gain, ROI, etc.

  6. Setup this program:

     pip install -e .
    

Usage

Live stream images

To see a live demosaiced display:

python sumix_demo.py -p

Note that the default is NOT to show the live preview as the preview is computationally expensive.

Write fixed number of images to file

python sumix_demo.py -n 10 -f test.h5

that is written to HDF5 (viewable with HDFView) HDF5 is a very common format in the science and engineering community and has superceded TIFF and FITS for many applications

sumix_demo.py options

  • -p show live preview (for focusing camera)
  • -f save multipage TIFF or HDF5 based on the file extension '.tif' '.h5'
  • -e set exposure (ms)
  • -x set ROI width
  • -y set ROI height
  • -d decimation (binning)
  • -g set image amplifier gain

Troubleshooting

You might have multiple copies of Python installed. For this program be sure you're using the 32-bit Python, perhaps by manually specifying on the Command Line the full path to Python.
