Cameras that are optimized to the imaging system can offer performance advantages and reduced system costs. For the most efficient custom camera, seek suppliers that combine engineering services and series production.
Small, low cost cameras for CCTV have been used for decades in banks, casinos, etc. where constant monitoring is required. Closed-circuit television (CCTV) is the use of video cameras to transmit signal to a specific, limited set of monitors as opposed to open broadcasting (source: http://en.wikipedia.org/wiki/Closed-circuit_television)
Click the image below for a video demonstration by IMEC of a hyperspectral imaging camera operating at fast frame rates. Spectral signatures of different type of leaf objects (paper printed leaf, plastic leaf, tissue leaf, real leaf) across 32 different spectral bands are being captured in parallel at 60 data-cubes / second and analyzed in…
The SPIE Defense, Security, and Sensing Exhibition is an opportunity for camera, sensor, optics, computer and other systems builders to share their latest innovations with the global security market.
With advances in filters, color processing, and overall sensor control by experienced camera designers, the shortcomings for single chip (Bayer filter mosaic) color cameras compared to 3-chip prism-based color cameras have nearly been eliminated. We have compared the different technologies with regards to image quality and color fidelity. Here we will compare with regards to…
Image sensors designed for machine vision applications are proving beneficial in traffic systems, such as automatic license plate recognition systems, because of their exceptional image quality and reliability in extended temperature ranges. Except, these image sensors are optimized for use under controlled lighting conditions and have challenges in outdoor lighting conditions especially extreme situations such…
Surveillance and situational awareness systems are relying on daylight full motion video more and more. The camera requirements for this use are unique and cannot be met by consumer cameras or machine vision cameras.
For OEMs building systems in series production, whether in machine vision equipment, medical devices, or global security products; repeatability and reproducibility of the cameras can be just as important as raw performance. Image uniformity can influence the accuracy of the system or the degree of closeness of measurements to the actual (true) value. But the…
With increased security concerns in recent years, surveillance has been intensified at airports, seaports, in cities, at borders, etc. To improve the information gathered from these systems, the big trends are the move from still imagery to full motion video and then better video analytics to automatically evaluate the images for unusual events.
