What an area camera is and what advantages it offers
Unlike single dimensional line cameras, area scan cameras capture a two-dimensional image of an object. That fundamental difference makes area cameras more universal and easier to integrate in general video capture systems. As line cameras and CIS solutions reveal their power in paper scan and surface inspection systems, area cameras show their strength in various fields: from professional cinematic applications, through surveillance, video aided robotics, endoscopy, to wildlife research projects.
Video heads with only 1 mm2 footprint
We develop and manufacture area cameras in two main groups: high fidelity and sensitivity, large sensor format devices and extremely small sensor format, miniature, low power consumption devices. Each of the groups has unique advantages. Our smallest battery-supplied area cameras have a video head footprint of just one by one millimeter, which makes them an ideal choice for endoscopy.
We offer area cameras for both grayscale and color capture. In both cases, we attach great importance to first class noise reduction and pixel noise correction. Not only for this we have developed some proprietary enhancements, that make our area cameras range among the best in the world.
Leading noise reduction without the slightest loss in sharpness: we place particular emphasis on noise reduction techniques, making our area cameras better than the competition in that aspect. We start with carefully designed electronic components to limit cross-talk and interference at their source. We also apply an advanced pixel noise correction feature. Unlike generic noise removal filters, the hardware implemented pixel noise correction is based on sensor measurement and each sensor response analysis. As a result, the module causes not even the slightest loss in sharpness. The pixel noise correction algorithm is our proprietary expansion of the column noise correction idea at the pixel level.
Excellent area cameras for both gray-scale and color capture: we offer area cameras for both grayscale and color capture. The color cameras require de-mosaicing algorithms, reconstructing full color information from the Bayer filter array covered sensor. A high-end de-bayering method optimized by BAPIS for individual sensor characteristics is based on an adaptive homogeneity-directed concept with some proprietary enhancements. The algorithm provides negligible sharpness loss and eliminates color artifacts thus exhibiting advantages over conventional de-bayering.
