CAMELIA 4M Digital Camera
5301C–IMAGE–03/04
Electro-optical
Performance
Conditions:
•
Frame integration time: 40 ms
•
Operating ambient temperature: 25
°
C
Notes:
1. LSB (Least Significant Bit): 12-bit = 4095 LSB or gray levels
2. Full-scale value VPE: maximum digital video signal
3. Temporal noise VN: r.m.s value in darkness; measured by subtracting two images
pixel to pixel
4. Dark signal non uniformity: r.m.s value; excludes blemishes
5. Dynamic range DY = VPE/VN
6. Responsivity conditions: CDS gain = 1x, 3200K, light source powered between 300
and 1000 nm, measured on the sensor
7. Resolution conditions: light source 3200K, BG38 2 mm, measured at
VIDEO = 2000 LSB, CDS gain = 1x
