CMOS Camera – P7: Streaming Lossless RAW Compression

Now this post will be for some serious stuff involving video compression. Early this year I decided to make a lossless compression IP core for my camera in case one day I make it for video. And because it’s for video, the compression has to be stream operable and real time. That means, you cannot save it to DDR ram and do random lookup during compression. JPEG needs to at least buffer 8 rows as it does comp ...

A Programmable Optical Slave Flash Trigger for Digital Cameras with Processor PIC 12F675

The synchronizer ensures a contact-free, optical synchronization of external photographic flashguns. The triggering of the external flash is derived from embedded flashes of a camera. It can be used for both digital and "analogous" cameras or for a remote synchronization of the actual flash units. Its use is optimal especially with digital cameras (DC), where extraordinary adaptability for different systems ...

Zeus: trigger your camera with lightning using pic microcontoller

Introduction I have always been fascinated by photographs about lightnings. While it is relatively easily to put a lightning strike in any photograph using image editing techniques :) I still prefer the real thing. Since photography is a hobby of mine, I wanted to be able to photograph lightnings. However, when I tried to do it without any specialized equipment, I didn't have much success. Reading a bit abo ...

Crossed IR Beam Camera/Flash Trigger

This device will trigger a camera or flash unit to automatically take a picture when an object (target) enters a specific location. It uses two, crossed infrared light beams to detect the presence of the target and close a relay that trips the camera or flash unit. Response time is about 2 ms from detection to relay closure, so if your camera doesn't have long shutter-lag, it will capture even fast moving t ...

Interfacing Camera with PIC Microcontroller via Matlab GUI

For project on security systems, Interfacing Camera with PIC Microcontroller via Matlab GUI is mostly desirable. But size internal ROM and RAM of PIC16F877 is very small. So it is very difficult or other word imposible to direct Interfacing Camera with PIC16f877 Microcontroller . But we can do it to introducing Matlab GUI and interfacing PIC16F877 with Matlab via UART communication using serial cable. Proje ...
