Video image processing project at the beginning

Turn to stop, stop and turn, or return to the image video aspect. At the beginning of 2015, in the video image this piece, at that time saw a lot of information, but because of the project, the project is not continuing. Now back to this starting point, the new starting point will have a new height!!!

Learn how to do without hardware board card, go to buy a board card? No! No! No! This is not the author's style!! Own design!!! On the one hand there is a sense of accomplishment, on the other hand has been engaged in hardware, hardware is more familiar with. Let's start with a holistic concept diagram.

Figure 1 overall block diagram

The FPGA control unit intends to use the EP4CE10E22C8N series, the user can use more pins, convenient control peripherals. About the Display unit section, there are 3 units to choose from, VGA display part, USB2.0 part, although now USB3.0, will certainly take care of you, wait!!! The use of USB2.0, is bound to involve the upper part of the computer, this part of the old age, I am afraid, may not be able to use the power of other great gods. LCD LCD display Part, this is the author's favorite, small LCD screen easy to display!!! Key and led test units are mainly in the algorithm, you can first use the led to measure the correctness of an output signal. Camera part of the author intends to design the interface as far as possible compatible with more camera models. Currently intends to access mt9v022,mt9v139,mt9m111,ov5642,ov7725,ov7670, and so on, first use these bar, on the tcd1209d before, this has been done before, to fight to be able to video display.

With the hardware Board card, do not do image algorithm that can not, to the time I will be the video image algorithm one by one write out, take the network, feedback network!

That's it, in the last few days to take care of USB2.0 part of the content (no contact is the mishap), other parts except SDRAM this big, other not difficult to fix. USB2.0 I come!!!!
