POEmbedded image capture - need help getting started
text
Body
copied!<p>I'm working on an embedded home surveillance system. I want to interface a couple of serial-enabled JPEG capture cameras, maybe a couple of door sensors, etc. Problem is, I can't for the life of me figure out how to interface a camera to a microcontroller. Stills, streaming video, it doesn't matter - I can't find any how-to documentation on this.</p> <p>I understand serial communications, and most of the camera documentation I've found out there describes the protocol necessary to instruct the camera to send the datastream down to the uC for capture. What they don't show is what you're supposed to do with the data once you get it.</p> <p><a href="http://www.4dsystems.com.au/prod.php?id=75" rel="nofollow">Here's an example</a>.</p> <p>They show a great little video, and the datasheet describes which bytes must be sent to the camera to retrieve the image. What I need is an example or tutorial of some sort that will explain what to do with the stream of bytes that make up the image itself. How do I arrange those bytes into an image and save it as a file? </p> <p>I've looked all over the place for a tutorial of some sort, but have come up dry. I'm not sure which processor I'll use for this project just yet, but this question isn't really processor-dependent. All I need is the algorithm, maybe a peek at a library, if one exists. I'll take that process and adapt it to my hardware, I just can't seem to find a place to get started.</p> <p>Have any of you done this? </p>
