1. Overview
This CCD color camera is a high-resolution color camera that features all pixel readout mode 1/1.8 CCD.

2. Features(1) High resolution
Bayer array high pixel density CCD (number of effective pixels 2.01 M, number of total pixels 2.11 M) is used.

(2) Square grids
The CCD pixels arrayed in square grids facilitates computation for image processing.

(3) Full-frame shutter
Since all pixels are output even by shutter operation, high resolution can be achieved, without deteriorating thevertical resolution.

(4) Camera link interface
The interface for image output and camera control complies with the camera link standard.
By using a camera link frame grabber board for camera link, the shot image can be transferred to PC at highspeed, and various camera controls can be performed from PC.

(5) All-pixel readout mode (normal mode)
All pixel signals (in the effective area) are output in approximately 1/15 second.

(6) Partial scan mode
Partial scanning of 552 lines in the center of the screen is possible.

(7) High-speed draft readout mode
By reading 2 lines from every 8 lines, all signals in the effective area are output in approximately in 1/48 second.

(8) Random trigger shutter
By external trigger signal input, the shot image can be grabbed at an arbitrary timing.

(9) Multiple-shutter
By external trigger signal input, the shot image can be grabbed at an arbitrary timing and the accumulated shot
images can be output at an arbitrary timing.

7. Explanation of operation
7.1 Readout mode
Video is output from the camera link connector. The output video can be grabbed by the frame grabber board.
The frame rate and resolution of output images that this model supports are as follows:
1) All pixel readout: Approximately 15 fps / 1628(H) x 1236(V)2) Partial scan

: Approximately 30 fps / 1628(H) x 552(V)3) High-speed draft readout : Approximately 48 fps / 1628(H) x 309(V)Notes on frame dropping:
When you use a grabber board for 32-bit PCI bus, images may not be grabbed correctly because
frame dropping occurs because too much data is transferred for the transfer rate of the PCI bus.
We recommend that, in this case, you should use a grabber board for 64-bit PCI bus.

Reads out all pixels in about 1/15 second.

7.2 Random trigger shutter
In the random trigger shutter mode, you can shoot and grab an image at an arbitrary timing by trigger
signal input from the external.
・External trigger signals can be input either from the camera link I/F CC1 or DC IN connector.
・If polarity is set to negative polarity, exposure starts at the falling edge of the trigger.
・The random trigger shutter of this camera can be operated in two types of mode: fixed mode and pulse
width mode. How to determine the exposure time differs depending on the mode.

1) Fixed mode
・The exposure time is determined by the setting value for the shutter speed.
・FVAL is output in sync with the first LVAL after the end of exposure time.

2) Pulse width mode
・The exposure time is determined by the pulse width (exposure time = pulse width + approximately 28μs).
・Set a pulse width of 1H (approximately 53.3μs) or more.
・FVAL is output in sync with the first LVAL after the end of exposure time.

7.3 Multiple-shutter mode
In the multiple-shutter mode, video is output in sync with a MULTI signal from the external after the endof exposure time.
・Valid only when the random trigger shutter mode is ON.
・MULTI signals can be input from the camera link I/F CC2.
・If exposure is executed several times before MULTI signal input, the images are output superposed.
・The exposure time is determined by the random trigger shutter mode setting and its determination method.
・The pulse width must be set to negative polarity and 1H (approximately 53.3μs) to 10 ms.
・FVAL is output in sync with the first LVAL after the end of MULTI signal input.
