The Raspberry Pi Foundation has been working on offering a camera attachment for Raspberry Pi boards for some time now. The developers began with a 41MP sensor, but have since moved to a smaller (and cheaper) camera with a 5MP sensor. That particular model is nearly complete and should be available for purchase sometime this spring, according to the developers.
The Raspberry Pi camera will be $25 which aligns itself well with the recently released Model A Raspberry Pi computer (which is also $25). The PCB hosting the camera module measures 20 x 25 x 10mm, while the camera module itself measures 8.5 x 8.5 x 5mm. It connects to the Raspberry Pi board via a flat cable into the CSI port below the Ethernet jack.
The $25 camera is capable of capturing HD video as well as stills. It uses the Omnivision OV5647 sensor and a fixed focus lens. The 5MP sensor is capable of capturing still photos with a pixel resolution of 2592 x 1944 and up to 1080p video. While the developers are still working on the kinks to ensure that it the camera can do this, the sensor itself is capable of 1080p30, 720p60, and 640x480p90 video capture. The Raspberry Pi Foundation has stated that at least the 1080p30 capture mode is working.
Interestingly, the Raspberry Pi ISP hardware can support two cameras, but the PCB only provides a single CSI connector (so no 3D image capture using two cameras). The Raspberry Pi Foundation is providing this little CSI camera as an alternative to USB cameras. While it is possible to use USB cameras with the Raspberry Pi, USB driver overhead and USB bandwidth issues specific to the Raspberry Pi limit the performance that you can get out of USB cameras. The $25 CSI camera add-on bypasses the USB interface in favor of the CSI port that feeds into the image processing parts of the ARM SoC.
The developers have not released an exact weight measurement, but have described it as being rather lightweight--making it ideal for use in drones, weather balloons, and other flying projects. For more information, the developers have set up a forum thread to answer questions and keep interested users updated on the project status.

Among the Crystal LED televisions Sony had a small pocket camera on display, the Sony Bloggie Live. The successor to the original Bloggie, the stylish camera fits in your pocket and somewhat resembles a smartphone in design.
The Bloggie Live features 8 GB of internal storage space, a 3" touch screen LCD, and a water resistant exterior. The ExmorCMOS sensor is capable of recording 1080p or 720p video, and the Wi-Fi radio is able to upload photos and videos to the various sharing services including Facebook, YouTube, Dailymotion, Flickr, and Picassa. The Bloggie Live has an LED flash and a stereo microphone. In addition to video, the camera is able to take 12.8 megapixel still photos. In addition, the camera is able to stream video to the internet over Wi-Fi using the Qik streaming service. Using the PlayMemories application, users are also able to wirelessly transfer files from the Bloggie Live to a smartphone.
Alternatively, Sony also showed off the Bloggie Sport, with is a bit smaller than the Bloggie Live and is waterproof up to 16 feet of water. This camera features 4 GB of internal memory, and is capable of shooting HD MP4 video and 5 megapixel still shots. An "Underwater Mode" further adjusts the white balance automatically.
The Bloggie Live is available for purchase immediately for $250 USD while the Bloggie Sport will cost $180 and will be available in February. The price tag is a bit steep considering the storage is not expandable and there is no external mic jack. Still, aesthetics wise, the new pocket camcorder looks slick.
