1. Outline
●
CCD line scan camera with 1024 pixels of image sensor and of 50MHz data rate.
●
Video signal is output complying with Camera Link standard (Base Configuration).
2. Features
●
It can perform high-speed inspection with 1024 image pixels at 50MHz data rate.
●
GAIN and OFFSET characteristic , 8/10 bit format etc. can be easily changed with RS232C command from
capture board.
●
The equipment operates with a single DC12V power source.
●
Reduction in size and weight has been realized by adopting original circuit and mechanism design.
●
Since the output signal level hardly vary among the ODD and EVEN pixels, It can display crisp image.
●
Exposure control function is incorporated.
3. Applications
●
Image processing device for Image inspection.
●
Foreign substance detector on high-speed production line
●
Surface inspection apparatus of sheet-like object .
●
Pinhole detector
4. CCD image sensor
The
CCD
image
sensor
Is characterized by
10
μ
m
square sized pixel, effective
1024
pixels, and high-speed and
high-sensitivity characteristic features.
Charges accumulated in single-row photo diodes are output thorough two shift registers, respectively.
(No.1 for ODD numbered charges, No.2 for EVEN numbered charges) Each shift register operates
at the rate of 50MHz.
