USB Camera noise reduction and PCB design correction
2003 (2 months), customer: “Sumix Corporation”, full-time, 1 developer/tester
result: Noise and temperature dependency reduced dramatically, about 30 boards were corrected
OS: Windows 98; languages: VB 6.0; tools: oscilloscope & solder iron
Sumix developed SMX-110 USB camera was inspected and tested for picture noise. Picture noise testing application was written using ready API.
Power modes, PCB design and camera construction were corrected to achieve as minimal noise as supplied CMOS sensor avails.
