Sony has devised a 360 degree solid-state single CCTV camera module

    Taking CCTV camera technology to a new level, Sony Europe Image Sensing Solutions' panoramic camera module allows full-circle, 360 degree images to be viewed in real time with no moving parts. This permits the end user to constantly view a full, live and undistorted panoramic image which, until now, could only be obtained by combining or 'stitching' shots together, or by taking multiple shots while slowly rotating the camera.

    The RPU-C251 model is initially being released as an OEM module aimed at systems integrators. Each unit contains a 1.3 megapixel, 7.5 frames per second CCD to output a ring-shaped image as a composite video signal. Proprietary Sony DSP technology ensures that the 'doughnut' image is then reformed as a perfect panoramic view.

    The mechanism that allows the full-circle 360 degree lens to see all of its surroundings is also revolutionary. On this Panoramic Annular Lens (PAL), the image of all the surroundings is reflected twice on two reflective surfaces (formed by the vapour deposition of aluminium), one in the lower part of the lens and the other at the top with the image being formed in a ring shape on the CCD.

    In operation, this allows everything around the lens to be imaged within a range consisting of 38 degrees above the plane of the lens and 17 degrees below (for the desktop mount model).

    There are no moving structural parts, thus PTZ operations can all be implemented in software. This dramatically reduces maintenance and keeps power consumption to a minimum, further reducing the total cost of ownership. Images can be formed as long as just the lens is exposed, so for safety and security the camera module may be embedded in a wall or ceiling.

    The RPU-C251 includes a converter board to supply a standard PAL, NTSC or VGA video output from the ring-shaped image captured by the CCD in a stand-alone, compact size. The inherent ability to provide both PAL and NTSC in one single product vision camera is rare but obviously very useful for end users.
