| KWD LOGLUX i5 Extraordinary pictures despite extreme light conditions Computer Vision very often is facing unsolved problems in applications where extreme light conditions occur. Scenes with high dynamic range are common in some industrial applications such as welding inspection, inspection of high reflective material (CD ROMs and other shiny material) or environmental applications like traffic control (at daylight, night, in tunnels with headlights on) and so on. In most of these demanding applications the CMOS camera from Kamera Werk Dresden will provide a solution. Quality Control in welding applications is a very good example to show the benefit of the LOGLUX camera. The arc represents the only source of light. The pictures were taken with the following exposure times:

The example pictures of a 100 W light bulb show results achieved with different exposure conditions. The use of a linear characteristics (common to most cameras) already shows a brilliant sharp picture with no blooming effects. Adding a second integration level (e.g. 3000 µs) results in a tremendous improvement of image quality within the low light areas without disturbing the bright shiny filament. A third integration step can improve medium portions again better. The improvement is seen best in the area of the supporting wires. The camera supports up to 4 windows simultaneously. The exposure for each window can be independently adjusted so that the respective image region is optimally illuminated. |

CMOS cameras are extremely resistant to blooming. Even with a linear characteristic you get sharp and clear images in extreme lighting conditions. If you want to see and evaluate structures in both dark and bright areas, you can adapt the sensitivity accurately. The pictures of the 100 Watt light bulb show impressively the features of the LOGLUX camera. 1 integration level 1000µs  2 integration levels 16000µs/500µs |
