1.
So, I want get a Histogram value from some specificity region for example
entire image size is 1280 * 960 and i want capture specificity region at
from 320 * 240 to 960 * 480 rectangle region and get a histogram data.
in the IC Capture 2.1 program specify ROI function that is I want function.
If I do this, which function is do that.
Please tell me function's name.

When I save entire image. The image size is 1280 * 960 size, then how can

Hi,

Q1: Please see the ROI filter at : http://www.imagingcontrol.com/en_US/support/documentation/class/stdfilterROI.htm

Q2: If you only want to save the Region of interrest, then please see Q1. If you want save the whole image resized, this is much more complictated. There is no function available, I can tell you.

Q3: There is no camera reset. If the device is lost, the camera usually is reset, depending on the device type. However, you may save a device configuration (state) after you have configured a camera with "SaveDeviceStatetoFile" and load this state into a video capture device using "LoadDeviceStatefromFile". Please refer to:
http://www.imagingcontrol.com/en_US/support/documentation/class/meth_descGrabber_loadDeviceStateFromFile.htm
http://www.imagingcontrol.com/en_US/support/documentation/class/meth_descGrabber_saveDeviceStateToFile.htm

Q4: You can enumerate all properties and set them to their default values. IC Capture does the same.
