Dear friend, How are you? I want to showing a photo from a Camera(like mobile cam) directly on a computer monitors(without computer),and with Pressing a key can take a picture and save it on memory. My big problem is here in making relation between camera and monitor, because showing an image on computer monitors from VGA port needs High frequency & High memory . Please introduce me any IC that I can use it as VGA Adaptor on ARM Microcontroller for making photo on monitor,and if you can tell me any other IC for optimized photo quality(like auto focus). Thank you for reading my email. Best Regards, Mirmoeini
