4 Camera Operation Overview
The camera operation is a 2 stage process that consists of exposure and data
output transfer. This process operates the same regardless of mode. The only
differences are the events that initiate exposure and data output transfer.
The LD3500 series cameras offer multiple exposure modes for maximum
flexibility to capture image data in a variety of applications.
4.1 Camera Exposure Modes (Camera Link Model)
The following exposure modes are provided:
The camera modes are selected selected by the serial connection on the Camera
Link connector. The camera communicates at 9600 Baud with 8 data bits, 1 start
bit, 1 stop bit, and no parity bits. Refer to PerkinElmer Applications Note ANP-
206.01A-8/2001 LD3500 Serial Command Language for more details.
4.1.1 Data Output
The digital video output is identical in all modes of operation. The digital video
is output together with two synchronization signals: Camera Clock (CCLK), and
Line Enable (LEN). The LEN signal brackets the valid digital video that is output
in synchronization with the CCLK. LEN is output on the LVAL signal line and
CCLK is output on the STRB signal line in accordance with the Camera Link
specification.
