1. Overview

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

2. Features

Rev 1.0

(1)

High resolution

Bayer array high pixel density CCD (number of effect ive pixels 2.0 1 M, number of tot al 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 the
vertical resolution.

(4)

Camera link interface
The interface for image output and camera control co mplies 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 high
speed, 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.
