image processing
We r using cyclone III EP3C120F780C7 .
Through DVI daughter card we want to send images to the board for processing and after that will retrieve those images again on the pc Please tell us it is possible for us to send single image through dvi to the board and if it is possible then what would be the source through we could send image We r going to use hyperspectral image17 Replies

Sending a single image via DVI would be possible, but it would easier to just have a video that contains a still image.
You question is rather vague. I suggest you form a more specific question. - Altera_Forum

we have separate camera module which will going to capture images and store on the COMPUTER .
After that our job is to take those images give it to the board for processing . For that we r using DVI daughter card. It has TR and RV end. My question is what would be the source through we can send images. Tell me whether if we could use computer as source for inputing images or else we require other sources such as cd or dvd player - Altera_Forum

If you're capturing on the PC, why are you sending them to the card via DVI? why not just via some data protocol? WHy not just have th DVI connectect directly to the daughter card?

we are not capturing image over pc, we will be capturing image on hyperspectral camera and that image we want to send it over dvi,so how can i do it .?is there any software so we can use pc's dvi to send images

--- Quote Start --- we will be capturing image on hyperspectral camera and that image we want to send it over dvi,so how can i do it .? --- Quote End --- Probably the easiest way would be to connect the hyperspectral camera DVI output directly to the FPGA card DVI input and to not involve the PC at all in this process. Interfacing the PC DVI output to the FPGA in a non-standard way (bypassing the operating system graphical user interface) is honestly more of a PC software question than an Altera FPGA question and you might have better luck researching that approach on a PC graphics card centric forum. - Altera_Forum

Camera does'nt come with DVI it's USB base camera
So now we r saving those images on PC Does it possible for us to send single single image to the board. Because we have PC with DVI OUTPUT but we don't know how to send only particular image to the board. According to me it will going to send entire window of PC including that image as it normally displays on the monitor Please suggest some idea - Altera_Forum

DVI is really a video interface. It would be much easier (and possibly quicker) to send single images via a data interface rather than DVI. How about RS232 (for easy FPGA implementation?) or ethernet or PCI if you have the cores avaialble?

The board do not have rs232 interface. It has only hsmc connector & ethernet. Itwould not possible using DVI ? We r thinking of sending images through DVI only. Please tell us if it possible to send single images through DVI or not. If it is then tell us how we would able to send only that much image from Computer using DVI

Yes you can send images via DVI, but it seems like overkill for a single image.

DVI is a video interface, so it is constantly streaming video data in the DVI. You cannot send a single image using it, you will have to send a still image as if it was a video from the PC.
