User Set Control
By setting various parameters of the camera, the camera can perform the best performance in different
environments. There are two ways to set parameters: one is to modify the parameters manually, and the
other is to load parameter set. In order to save the specific parameters of the users, avoiding to set the
parameters every time when you open the camera, the MER-G-P/MER-G series camera provides a
function to save the parameter set, which can easily save the parameters that the user use, including the
control parameters that the camera needed. There three types of configuration parameters: the currently
effective configuration parameters, the vendor default configuration parameters (Default), and the user
configuration parameters (UserSet).
Three operations can be performed on the configuration parameters, including save parameters
(UserSetSave), load parameters (UserSetLoad), and set the startup parameter set (UserSetDefault). The
UserSetSave is to save the effective configuration parameters to the user configuration parameter set
which is set by the user. The UserSetLoad is to load the vendor default configuration parameters (Default)
or the user configuration parameters (UserSet) to the current effective configuration parameters. The
UserSetDefault is refer to the user can specify a set of parameters which to be loaded into the effective
configuration parameters automatically when the camera is reset or powered on. And the camera can work
under this set of parameters. This set of parameters can be vendor default configuration parameters or
user configuration parameters.
1)
The type of configuration parameters
The type of configuration parameters includes: the current effective configuration parameters, vendor
default configuration parameters, user configuration parameters.
The current effective configuration parameters: Refers to the current control parameters used by the
camera. Using API function or Demo program to modify the current control parameters of the camera is to
modify the effective configuration parameters. The effective parameters are stored in volatile memory of
the camera, so when the camera is reset or powered on again, the effective configuration parameters will
be lost.
The vendor default configuration parameters (Default): Before the camera leaves the factory, the camera
manufacturer will test the camera to assess the camera's performance and optimize the configuration
parameters of the camera. The manufacturer's default configuration parameters are the camera
configuration parameters optimized by the manufacture in a particular environment, these parameters are
stored in the non-volatile memory of the camera, so when the camera is reset or powered on again, the
effective configuration parameters will not be lost, and these parameters cannot be modified.
The user configuration parameters (UserSet): The effective parameters are stored in volatile memory of
the camera, so when the camera is reset or powered on again, the effective configuration parameters will
be lost. You can store the effective configuration parameters to the user configuration parameters, the
user configuration parameters are stored in the non-volatile memory of the camera, so when the camera
is reset or powered on again, the user configuration parameters will not be lost. The MER-G-P/MER-G
series camera can store a set of user configuration parameters.
2)
The operation of configuration parameters
The operations for configuration parameters include the following three types: save parameters, load
parameters and set the UserSetDefault.
