LinkSprite Camera TTL interface_Please Help

Hi,

I have Linksprite camera and Arduino Uno. I want to get pictures to my computer. I found some codes for arduino about camera. From serial monitor I couldn't read any information. Some codes I think are working but serial monitor gives me some HEX number. It doesn't mean anything for me how can i see cameras visuals. I have one more question, there is one code for arduino and i think it's taking a picture but i takes 10-15 seconds. Does it to much time to take picture ? how many times do i need taking picture with Arduino ?

Thank you,
