Camera ISp in OMAP3530

What is the functionality of Prestrobe and Strobe Signals?

Why and when these signals and its counters to be used?

These signals appear to be for digital still camera applications, namely when you would connect with a camera that has a flash these signals likely help to handle the timing of the flash. If the camera module you are interfacing to does not have a flash strobe signal on it than you can likely ignore these signals.

Thanks for your support.

I think cam_shutter is also for digital still camera application and not for video camera.

i am not clear about cam_wen signal functionality.can you explain about this.

Let us assume i am interfacing a video camera and my input is YUV4:2:2 data.For this what are the configuration is must.

Thanks and regards,

The cam_wen signal is another signal that you would normally use with image sensors, some sensors provide a write enable output, a.k.a the data now being sent is valid. It is a way of blocking out portions of the image that may not be valid, of course if your particular image sensor does not have such a signal you can probably ignore this.

This depends more on the format of your data, generally a video decoder will provide a bt.656 standard data stream which would be accepted by the ISP, in which case you would configure the ISP in ITU mode as discussed in section 12.2.4.3 of the TRM. Of course there are exceptions, just knowing that it is a camera of some sort and YUV 4:2:2 data is not enough to truly determine what the ISP configuration would be.

Thanks alot Brenie.

First thing am trying is to store the image data straightly in OMAP memory without frontend and backend processing. After got successful in this i will try for frontend and backend processing.

Please refer the section 12.4.1.1.2. In this section i am planing to use path C. Please let me know whether this is correct option to store directly in memory. 

From section 12.4.1.1.1,12.4.1.1.2,12.4.1.1.3 my understanding is all the images must pass through CCDC module in which the sub modules like optical clamping, faulty pixel correction,data formatter,reformatter,LSC can be enabled or disabled individually.Please clarify this.

For storing image data straightly in memory with out video processing, Please clarify the following

1. i must enable(Program) the Timing CTRL, CCDC,SBL,CBUFF modules in Camera ISP

2. Whether i need cam_hs, cam_vs,cam_fld from the camera which is going to interface with Camera ISP.

3.ISP configuration details

Thanks and Regards,
