Photography Camera - Star Light Camera
1/3" Sony Super-HAD CCD, 580TVL, 0.001Lux, Supplied W/O lens
The MTV-63V1 features special 'starlight' technology which allows it to provide a clear colour image under low lighting conditions. With this, the onboard DSP allows the shutter speed to go lower than the normal exposure mode of 1/60 or 1/50 sec. This allows photons to be accumulated for 2 to 128 times longer then normal. Thus the minimum illumination is increased by a factor of 2 to 128 times.
The user can turn on the 'starlight' mode (slow shutter frame integration) via the on-screen-display buttons. In the 'starlight' mode under decreasing lighting conditions, the AGC attempts to compensate until it cannot maintain the 100 IRE video level. The 'starlight' mode then kicks in and the shutter speed starts to drop from 1/60 to 1/30, 1/15, 1/8 1/4 1/2, 1, 2 ,4 ,8 ... and all the way down to 1~10 sec.
One can set the camera for AGC mode or for SLOW SHUTTER mode. The shutter priority mode is used in machine vision and astronomical applications especially for steady object observation, and where good picture quality is the priority. AGC priority mode is used for surveillance, traffic control and military applications where fluid motion pictures are important.
Super Backlight Compensation
Another important feature of the MTV-63V1 is the advanced backlight compensation (Super BLC). This function provides perfect camera exposure for an object in front of strong background lighting. Thus preventing the main object from being too dark to see. Onboard intelligence provided by the DSP allows the camera to change the BLC 'weight' zone from the center to any portion of the screen automatically following the main object's movement.
