Base TRD supports high dynamic range (HDR) video with capture and display pipelines, following is a brief introduction.
Multi-exposure Digital Overlap High Dynamic Range (DOL-HDR) capture
High dynamic range image is a technique obtained by combining several different exposures frames of the same subject matter. IMX274 camera sensor supports capturing objects at two different exposure, HDR extract IP segregates the sensor data (DOL data) into short and long exposure frames. HDR merge will generate the HDR frame form the data obtained. The HDR frame results in an image with a greater dynamic range than what is possible by taking one single exposure. HDR is useful for recording many real-world scenes containing very bright, direct sunlight to extreme shade.
Note:
Only Platform 1 has the ability to capture HDR frames.
4k HDR video in platform 1 has a max framerate of 30fps, limited by the sensor.
High Dynamic Range Display (HDR10)
The dynamic range of a display refers to its luminance, the maximum and minimum amount of light the display is capable of producing. High dynamic range(HDR) is the capability to represent a large luminance variation in the video signal, i.e., from very dark values (0.00005 cd/m2) to very bright values (greater than 1000 cd/m2). HDR creates brighter whites, darker blacks, and brighter colors that better match images we see in the real world. HDR10 uses ST2084 EOTF, a single content layer with static metadata, this static metadata information is supported in the underlying infrastructure of the platform 3 TRD vck190_hdmiRx_hdmiTx mentioned above, where both source and sink elements are HDR10 capable (HDMI-RX and HDMI-TX).
