Additionally, the RX1 camera features By Pixel Super Resolution digital zoom technology, which allows for magnification of image size without sacrificing pixel count.
It introduces brand-new 'Clear Image Zoom' that boosts magnification without lowering the pixel count in the final image.
This image sensor layers the pixel section containing formations of back-illuminated structure pixels onto chips containing the circuit section for signal processing, which is in place of supporting substrates for conventional back-illuminated CMOS image sensors.

The team of astronomers is using data from the VISTA Variables in the Via Lactea programme (VVV), one of six public surveys carried out with VISTA. The data have been used to create a monumental 108 200 by 81 500 pixel colour image containing nearly nine billion pixels.

Conventional CMOS image sensors mount the pixel section and analog logic circuit on top of the same chip, which require numerous constraints when wishing to mount the large-scale circuits such as measures to counter the circuit scale and chip size, measures to suppress noise caused by the layout of the pixel and circuit sections, and optimizing the characteristics of pixels and circuit transistors.

"As mobile devices like smartphones and tablets get smaller and thinner, the pixel size of image sensors needs to shrink accordingly, " said Andrew Burt, vice president of the Analog and Imaging Business Unit, System LSI Group at TAEC.

Each mirror acts as a beam-steering device, controlling whether a single picture element (pixel) in the image is light or dark.
In addition to the higher pixel numbers, superior image quality and faster speeds which conventional image sensors pursued, the newly-developed image sensors further achieve more highly-advanced functionalities and a more compact size, thus paving the way for enhanced camera evolution.

This arrangement makes the chip particularly suitable for image-processing, because each analogue element of the array can be made to correspond to a single pixel (one of the individual dots of which an image is composed).
Toshiba addresses the challenge of pixel miniaturization with its newest CMOS image sensor.

With the extremely high pixel count of the full-frame image sensor, even zoomed and cropped images maintain generous amounts of fine detail when blown up for large print sizes.
If it senses that you've fixed your gaze on a specific location for more than a few seconds, a nose-bridge mounted HD camera will take a 50 x 50 pixel snapshot and compare it to its image database -- much like Google Goggles.

Furthermore, as the pixel section and circuit section are formed as independent chips, a manufacturing process can be adopted, enabling the pixel section to be specialized for higher image quality while the circuit section can be specialized for higher functionality, thus simultaneously achieving higher image quality, superior functionality and a more compact size.

However, instead of each pixel representing a colour, as in the image on a screen, these readings show all the different chemical compounds present in each of the thousands of tiny patches that together make up the sample.
'By Pixel Super Resolution' technology also significantly boosts still image quality during movie recording.
The Foveon X3 direct image sensor captures all primary RGB colors at each and every pixel location with 3 layers, ensuring the capture of full and complete color.

So... hyperbole aside, the FX30 is thin and features a 3.6x LEICA DC VARIO-ELMARIT optical zoom lens, 7.2 megapixel CCD, Mega OIS optical image stabilization, Venus Engine III image-processing for shooting at ISO 1250, and a 2.5-inch 207k pixel LCD (the L74 throws down 230k pixels) with "Power LCD" to boost brightness by 40% (at the expense of battery life) when outdoors.

He came up with the 80m figure by multiplying the number of dots, or pixels, in a high-resolution image (about 1m-2m) by the number of surfaces that an imaginary ray of light corresponding to each pixel would encounter as it bounced around a complex scene (say, 50-100).
