Image Flip/Mirror; Embedded Image Information - FLIR GRASSHOPPER 3 Series Technical Reference

both the darkest and brightest areas of an image simultaneously - darker portions of the image are too dark or
brighter portions of the image are too bright. High Dynamic Range (HDR) mode helps to overcome this problem by
capturing images with varying exposure settings. HDR is best suited for stationary applications.
The camera can be set into an HDR mode in which it cycles between 4 user-defined shutter and gain settings,
applying one gain and shutter value pair per frame. This allows images representing a wide range of shutter and
gain settings to be collected in a short time to be combined into a final HDR image later. The camera does not
create the final HDR image; this must be done by the user.
The HDR interface contains gain and shutter controls for 4 consecutive frames. When Enable high dynamic
range is checked, the camera cycles between settings 1-4, one set of settings per consecutive frame.
To enable HDR:

8.16 Embedded Image Information

This setting controls the frame-specific information that is embedded into the first several pixels of the image. The
first byte of embedded image data starts at pixel 0,0 (column 0, row 0) and continues in the first row of the image
data: (1,0), (2,0), and so forth. Users using color cameras that perform Bayer color processing on the computer
must extract the value from the non-color processed image in order for the data to be valid.
Each piece of information takes up 32-bits (4 bytes) of the image. When the camera is using an 8- bit pixel format,
this is 4 pixels worth of data.
