Aerial Cameras

IMPERX cameras deliver worry free use with an extended temperature range of -40°C to +85°C and shock/vibration performance of 1000G/100G. The IMPERX design is a MIL SPEC 810F product that has a MTBF > 660,000 hours @ 40°C. The extremely low power and small design is effective in small spaces and has a configurable mounting design and selectable mount option to support almost any lens on the market.

I/Os

IMPERX offers several ways to have a multi-camera system communicate with flight computers and with precision methods for knowing precisely where the image was taken. By offering multiple inputs and outputs, we allow the user synchronization capabilities, IMU and GPS communication and precise control of exposure. The user can communicate with the camera with H- and V-Sync pulses to perfectly match the timing of the airborne system with other cameras. IMPERX also provides signals such as camera integrating, camera ready, center strobe pulse, trigger pass through and more for flight computer, metadata and image geo-rectification.

Auto-Exposure/Gain

IMPERX cameras feature auto exposure and auto gain designed around airborne imaging use. Since airborne imaging or mapping revolves around 1 to 2 frames per second, it is more challenging for the user to determine the intensity of the next frame. IMPERX provides a fast convergence with histogram for a smooth transition, but extremely accurate exposure/gain control. The user can define the maximum amount of exposure time for the camera to properly throttle the gain for the optimal average intensity without motion smear. The AEC and AGC algorithms allow the user to set average intensity vs. maximum intensity of the image as well as a user definable area to normalize the light intensity around.

Image Enhancements

IMPERX knows the most important part of airborne imaging is the ability to identify what is being imaged. IMPERX cameras have 12-bit look up tables to allow the user to configure the contrast of the image to suit their needs. Whether the user needs simple single knee point corrections through complex 3d LUTs, the camera will do the adjustments on-board. In addition to the advanced look up tables, the camera will handle color adjustments and real time auto white balance, flat field correction and noise correction. For extreme users, IMPERX features digital bit shifting to provide the location of the most significant bits.
