Abstract

A method that can detect targets is described. The method includes setting an integration time for each of a plurality of readout circuits based on a speed of the target. The readout circuits are configured to read pixels in an image detector. The pixels have a pitch of less than ten micrometers. The integration time is not more than five hundred microseconds and corresponds to a subframe of a fast frame image. The method also includes performing integrations of each readout circuit based on the integration time. Thus, a plurality of subframes are provided. A number of the subframes are averaged to provide the fast frame image.

Abstract

Techniques for tracing back a projectile to the projectile origin are described. A method includes detecting projectile track(s) in image(s). Each projectile track crosses multiple pixels in each image. The projectile track(s) correspond to projectile(s). The projectile track(s) in the image(s) are translated to traceback path(s). The traceback path includes a known location and a projectile origin (e.g. the location at which the projectile originated, also termed the shooter's location).

Abstract

A method is described, which includes receiving oversampled infrared data provided from an infrared pixel array. The method also includes performing at least one of selective median filtering, spatial-temporal filtering, or resolution enhancement for the oversampled infrared data. In some embodiments, the selective median filtering is performed before the spatial-temporal filtering and the spatial-temporal filtering is performed before the resolution enhancement.

Abstract

Detection of a target object or a characteristic of that object, e.g. temperature or movement in an image of a scene at a focal plane of the image and with processing of signals representative of the image occurring at that focal plane with a sensor and an integrated circuit processor on an imaging circuit chip used to record the scene. Moreover, processing of the signals representative of the image and the object or characteristic of the object can all be processed in parallel. This arrangement allows for filtering of objects with the ability to distinguish the object generating signals from background clutter. The incorporation of the entire circuit in this integrated circuit chip increases the compactness and efficiency. Moreover, all signal processing will occur at the focal plane eliminates the need for external processing electronics thereby increasing compactness and efficiency while reducing spatial noise.
