Part 5: Optimizing Camera Parameters for Image Quality
Introduction
The quality of an image depends on multiple factors including illumination, lens characteristics, and camera settings. This article focuses on how to properly configure camera parameters to achieve superior imaging results.
Shutter (Exposure Time)
The shutter controls the exposure duration of the CCD sensor. Users can operate it either manually or automatically. The following sample images demonstrate different exposure scenarios:
Sample 1: Correct Exposure
- Key ring with LED light off is captured clearly
Sample 2: Insufficient Exposure
- Shortened exposure time results in underexposed image
Sample 3: Excessive Exposure
- Extended exposure causes overexposure, creating a large white spot
When the LED was activated during testing, we observed significant overexposure. The solution involved reducing exposure duration to accurately capture the light source while addressing an accompanying vertical artifact known as “smear”. This issue typically arises from CCD sensor limitations and can be mitigated by adjusting aperture settings while potentially increasing exposure time.
