Integrator and image store (H)
The integrator / image store module is internally applied for the automatic
selection of the correction set (
k=) and the recording of new temporary refer-
ence image data ( A=FF, B=FF). Furthermore this module may also be con-
trolled manually. The data are stored in the volatile SDRAM memory. They are
lost after the camera is switched off.
The bits of the parameter value are divided into four different sized bit groups
a, b, c and d. Each bit group has a special function, being independent of the
other ones:
• a: Controls the output of integrator module. Either the incoming data are
passed through transparently or the actual memory content of the inte-
grator is output. In the latter case, the integrator becomes an image
source itself. In this way, this module has a simple image storage function.
• b: Defines the number of images to be integrated and starts the
integration process as soon as a new value is set.
• c: Controls the data copy mode. The image storage content of the
integrator is copied into the correction data storage as low or high
reference image of the two-point correction (parameter
A or B in the
active memory page S) at any time. The data copy mode should stay
active for a minimum period of two complete image cycles in order to
guarantee a save data transmission into the target area.
• d: Indicates whether the last started integration is still running. This bit
can only be read out; during write access to
H, it is ignored.
The table below illustrates the possible values for the individual bit groups:
