FCB-EX Series colour block camera with advanced Digital Signal Processing (DSP) and a 1/4-type EXview HAD CCD
Combining a newly developed DSP with a 1/4- type EXview HAD CCD, these cameras achieve a high horizontal resolution of 530 TV lines, enabling reproduction of amazingly clear and detailed images
The FCB-EX Series of cameras incorporate an advanced backlight compensation technology that dramatically improves camera dynamic range by 128 times when compared to conventional cameras, resulting in clear image reproduction in extreme high-contrast environments. These cameras capture the same image twice - first with a normal shutter speed, and then with a high shutter speed. The dark areas captured at normal shutter speed and the bright areas captured at high shutter speed are then combined into one image using an advanced DSP LSI, thus clearly reproducing the original scene.
These cameras are equipped with a Slow AE response function to automatically slow the rate at which camera exposure levels change. The rate can be set up to 32 times slower than when Full-Auto AE or Priority (shutter/iris) modes are selected (the rate at which camera exposure levels are adjusted when in Full-Auto AE or Priority modes is just under one second). This function is useful when monitoring areas in which lighting conditions change abruptly. For example, if the camera is used to monitor the flow of nighttime traffic when vehicle headlights are pointed directly towards it, the camera's exposure level is reduced slowly. This can allow users to monitor and identify crucial parts of the image that surround the headlights, such as the car's license plate or the driver's face.
the FCB-EX490D/EX490DP cameras incorporate an 18x optical zoom lens. Users can choose a camera that has the appropriate zoom ratio for their specific application requirements.
In addition to conventional colour masking, unwanted or prohibited areas within an image can be masked using a mosaic effect. A maximum of eight masking areas can be displayed on the monitoring screen. Also, if these block cameras are incorporated into a Pan/Tilt/Zoom (PTZ) camera system, masked areas are interlocked with PTZ movements, regardless of the camera angle or even if it is circling. Up to 24 masking areas (the maximum number of masking areas that can be displayed on the monitoring screen at one time is eight. When more than eight masking areas are preset, users should take caution to ensure that no more than eight masking areas appear in a single view) can be preset in the entire viewing range of the PTZ camera.
These cameras incorporate a video motion detection function. When motion is detected within an area of the picture designated by the user, an alarm signal is output via the camera's control interface using the VISCA protocol. Users can designate up to four detecting areas freely from any of 8 vertical and 12 horizontal blocks.
Up to eleven lines with 20 characters per line can be displayed on the monitoring screen using VISCA commands. Users can freely display captions on the screen such as monitoring location, camera name, and alarm messages, providing operators with a user friendly interface.
These cameras have an e-Flip function that electronically flips an image upside down so that it is displayed on the monitor accurately. In a dome application for example, if a tracked object moves beneath the camera dome, the image is inverted to maintain the correct orientation.
These cameras incorporate SMART Lens Control technology that monitors the focus position of the lens during while zooming and automatically compensates for any mechanical misalignment that may occur over long periods of continuous usage. With the introduction of SMART Lens Control, periodic lens initialisation is no longer required during continuous 24-hour operation.
For optimised sensitivity in both day- and night-shooting applications, these cameras incorporate an Auto ICR function. At a set level of darkness, the IR-cut filter is automatically disabled (ICR ON) and the infrared sensitivity is increased. At a set level of brightness, the filter is automatically enabled (ICR OFF). The IR-cut filter automatically engages depending on the ambient light, allowing the camera to be effective in a variety of lighting conditions.
The FCB-EX Series of cameras are equipped with a Picture Freeze function that allows for the output of a still image while the camera is panning, tilting, zooming, focusing, initialising the lens, or performing preset operations. For example, the camera will output a still image before it begins to pan, tilt, or zoom, and once the operation is completed, the camera continues to display images that are currently being monitored; in this way, unnecessary images are not displayed.
