The Need for Embedded Ultra HDR™ Video in Vision Applications
In the past, developing higher quality video has been accomplished on two axis; higher resolutions for sharper, more detailed video and higher frame rates, based on faster pixel readouts in CMOS sensors to capture motion without blur and provide slow motion playback.
Now, a third axis is possible for creating higher quality video in high contrast situations, solving the problem of capturing enhanced data and detail in deep shadows, while holding highlight detail, with a single sensor. It’s called Ultra HDR™ video from Pinnacle Imaging Systems. Ultra HDR™ has the ability to add value, enhance data acquisition and provide higher quality in many video application segments.
Applicable Ultra HDR™ Segments
Today, signal processing of highly computational intensive tasks, using advanced logic, combined with highly developed algorithms makes it possible to provide dynamic range well beyond what any single sensor can provide. This opens up new opportunities for improvement in existing video applications, capturing more information for recognition and other computational tasks and providing higher quality video.
Pinnacle Imaging Systems’ Ultra HDR technology addresses many of the complexities involved in HDR video capture including:
- Automatic Ghost Removal & Halo Reduction – Compensates for movement between HDR exposures, from minimal camera motion to moving objects between frames
- Locally Adaptive Tone Mapping – Automatically optimizes the tone mapping parameters based on the shadow and highlight areas of each individual video frame to ensure a more natural look to the output video
- Automatic White Balance Controls – Automatically calculates proper white balance settings for any scene or lighting condition
- Automatic Exposure Controls – Real time calculation and adjustment of the sensor’s exposure settings based on an automatic or manually selected region of interest to allow accurate exposure throughout a scene
- Shadow Exposure Bias Option – Ability to bias tone mapping with an additional Shadow Tracking option during the Auto Exposure mode for optimal shadow detail and data preservation, a key requirement for surveillance applications
