storage, photography, film, disk
Film professionals can now store hours of digital films without compression using a new on-camera recorder.
FlashBox, developed by researchers at the Fraunhofer Institute for Integrated Circuits (IIS) in Germany, docks directly onto a movie camera and records images for digital cinema and high definition (HD) in a resolution of up to 2,048 x 1,080 pixels.
The images are stored on solid-state disks that operate in two slots so that the disks can be exchanged. The Fraunhofer researchers claim that, together, these disks can store 500Gb of film takes.
The production of digital motion pictures requires shooting individual scenes of 20-50Gb and this data needs to be stored on set.
FlashBox is claimed to simplify the entire film production process by allowing digital movie cameras such as the ARRI D21 or the Sony F35 to send uncompressed data for storage.

silicon, photography, wide-angle, camera
Mimicking the curves of a human retina has enabled a digital image sensor to take wide-angle pictures without distortion. This is possible thanks to an improved method of transferring silicon sensors onto a curved surface.The electronic eyeball design can allow small cameras to capture wide-angle views with low distortion. That could be useful in a range of situations, from policing, to attaching cameras to wildlife.
Conventional film and digital cameras use a flat surface to capture an image and as a result are unable to capture a wide field of view without distortion. Optics designed to correct such distortions can be complex and expensive.Silicon doesn't bend easily and can't be forced into a hemispherical form without creases appearing in the material.
John Rogers at the University of Illinois at Urbana-Champagne and colleagues have now worked out a way around those problems, using conventional chip manufacturing technology.

Samsung Electronics announced today an 8.4 megapixel (Mp) CMOS image sensor (CIS) at Samsung’s fourth annual Mobile Solution Forum.
The new CIS chip provides a high signal to noise ratio (SNR), a key measure of overall image quality. Samsung achieved the high-resolution level by implementing advanced light sensing features and minimized noise levels. Notably, an extended photo diode technology was implemented to achieve higher light sensitivity and saturation levels, resulting in an enhanced fill factor.
Furthermore, it provides the same image quality as the charge-coupled device (CCD) image sensors currently used in most digital cameras and camcorders. Since the new CIS only uses one-tenth the power of a CCD image sensor, it should quickly replace CCDs in all three key applications-mobile phones, digital cameras and camcorders.

digital imaging, photography, camera
Richard Baraniuk and Kevin Kelly have a new vision for digital imaging: they believe an overhaul of both hardware and software could make cameras smaller and faster and let them take incredibly high-resolution pictures.
Today's digital cameras closely mimic film cameras, which makes them grossly inefficient. When a standard four-megapixel digital camera snaps a shot, each of its four million image sensors characterizes the light striking it with a single number; together, the numbers describe a picture. Then the camera's onboard computer compresses the picture, throwing out most of those numbers. This process needlessly chews through the camera's battery.
Baraniuk and Kelly, both professors of electrical and computer engineering at Rice University, have developed a camera that doesn't need to compress images. Instead, it uses a single image sensor to collect just enough information to let a novel algorithm reconstruct a high-resolution image.

Samsung Electronics has started selling the world's first 10 megapixel mobile phone (model: SCH-B600) in South Korean market.
Samsung's 10 megapixel camera phone is 6mm thinner and 10g lighter than the 7 megapixel camera phone (SCH-V770) and sets itself apart from its previous megapixel camera phones by combining mobile TV capability in Satellite standard.
The B600 offers the same level of picture-taking sophistication that a 10 megapixel digital camera offers. The camera function includes 3x optical zoom and 5x digital zoom. It also has auto focus and a flash unit that performs optimally for 10 megapixel photographs.
