It also provided simple image processing feature for particles analysis. 2. Camera User Interface 1. Preview Image – show live video of the camera. 2. - Page 8 4. Adjust image parameter of camera When the color of image is not very good, adjust the effect of image “Effect” panel. Exposure: Auto mode: Brightness of the image will be automatically adjusted, you can also adjust the target brightness. Manual mode: Manually adjust exposure time and gain.
- Page 9 Enter calibration mode Follow the Tips： 1. Drag the yellow ruler, let endpoints of the ruler close to physical ruler’s scale. We use the 0.01mm physical ruler, each big grid is 10μm, we pick two grid, that’s 20μm. www.optoedu.com Page 9 of 15 sale@cnoec.com...
- Page 10 2. Input the name of the calibration and the physical length of the ruler. We input 40x for the name, that means the magnification of objective is 40X, Then input the physical length of the ruler, that is 20μm. 3. Click “Calculate” to calculate the calibration value for current objective and preview size, and save to list.

Page 12: Image Analysis
Use the line ruler to measure the physical ruler. We measured 1.5 big grid, the line ruler show 14.910μm, that represent the result is right. 6. Image Analysis Image is an application which used to process microscopic images on Android devices. It depends on computer vision library Open CV. - Page 13 6.1.2 Convert the image into gray scale Choose “Grayscale” function from left sidebar, click “Apply” button to confirm conversion. 6.1.3 Adjust contrast and brightness Adjust contrast and brightness of the gray scale image, increase the difference between the objects and background 6.1.4 Binarization With the binarization tool, you can change the minimum and maximum value of threshold.
- Page 14 Note: Try to make the red area do not overlap each other. 6.1.5 Particle analysis After apply binarization, open particle analysis tool: First of all, because some noise or dirty point was not clear by binarization. You need set the range of particle’s size.
