A masterpiece in the making.

A flagship is born

Have digital cameras become boring?

Has digital camera technology reached maturity? Or is it just that no real innovations have appeared in so long. Certainly, the digital camera front has offered little to get excited about in recent years.

This observation, shared by most photography enthusiasts, is a fair, if harsh, judgment on the current state of the digital camera industry.

At Sigma, we have taken this criticism to heart.

rapid popularization and the accompanying innovations in performance and convenience, you would be excused for getting the impression that nothing remains to be accomplished.

Appearances to the contrary, digital cameras and imaging are in a period of turmoil.

Measured against the long span of photographic history, digital photography is still in its formative years. In Sigma's view, there is still considerable room for development.

determines image quality — the overwhelming majority of digital cameras are still on the same well-worn road. Their fundamental technology has not changed since the digital camera's babyhood.

It is precisely here — in this key area of the capture system and image generation process — that Sigma is charting a new course.

During the burst of digital camera market growth in the second half of the 1990s, innovations appeared at a rapid pace in the areas of pixel count and image processing technology, including white balance and noise reduction, not to mention auxiliary functions like face recognition. Real progress was being made and there was plenty to talk about.

The idea that digital imaging technology is already mature is, in Sigma's opinion, open to debate.

Radical technology for real quality

With the huge popularity of digital cameras, people are using them in new ways. Digital images are playing ever more important roles in our daily lives.

More recently, digital cameras have gained still higher pixel counts, video capability, and other functions that provide practical benefits and convenience. These advances were offered with the best of intentions

— people desired them. But if this same progress is also behind the feeling that cameras have gotten boring, perhaps it is time to rethink what a digital camera should be.

As in the past, photography is an ideal medium for preserving memories and expressing creative visions. What is new is the use of photos as communication, particularly through photo sharing sites and social media. In this new domain, photos are part of a person's online presence, a way to share interests and a catalyst for relationships.

Technology in turmoil

The first electronic still camera appeared about 30 years ago, and mass-market digital cameras have been around for about 15 years.

Looking back on the many stages of photographic innovation since the

19th century, you can see just how young the digital camera really is.

Considering the digital camera's

Technology and functionality continue to evolve to support these new applications. Today's digital cameras are designed to make it easy to perform many tasks, thereby encouraging more people to enjoy photography without hesitation. This is a good thing.

But when it comes to the critical core of digital photography — the image capture system that

With a single-minded focus on generating true, high quality images, Sigma is the only digital camera maker dedicated to developing direct image sensor technology and cameras that incorporate it.

Irreplaceable moments, immortalized

Moving scenes, candid shots, breathtaking scenery ….

To preserve these moments truthfully with all their evocative power, the image capture system is of overarching importance.

As the bedrock of photographic veracity, the capture system should be the primary target of research, development and innovation efforts. After all, photography exists to reflect truth, and cameras exist to take photographs.

We are not denying the success of developments aimed at making cameras easier to use.

We simply believe in going to the heart of the matter by focusing on innovation that actually improves the quality of photographs.

Just as film followed an evolutionary path of incremental improvement, so the digital camera's image capture system must steadily and resolutely evolve to realize its full potential.

There is much to be done and we are set on doing it.

An image capture system you can believe in.

Now, more than ever

Direct image sensor

Color filter array (CFA) sensor

08

R: 100% G: 100% B: 100%

Full color capture system has three layers of photo detectors, enabling it to capture 100% of

RGB color information directly.

R: 25% G: 50% B: 25%

With a conventional digital camera's sensor,

50% of the photosites are dedicated to green, and 25% each gather red and blue color information via a color filter array.

Not another monochrome sensor with color filters

The image sensor in almost all digital cameras, with the exception of Sigma's, is a color filter array (CFA) sensor. The image sensor itself is monochrome; it detects light intensity, but not color. The CFA overlaying the sensor's light-sensitive photodiodes is a mosaic of red, green and blue (RGB) filters in a checkerboard-like grid. Therefore, each photosite, corresponding to a single pixel, receives just one of the three primary colors.

In this kind of system, a 15MP CFA sensor allots 7,500,000 pixels to green light and

3,750,000 each to red and blue light, respectively. Left as is, this checkerboard pattern would create a strange image, so a process called color interpolation is used to blend in neighboring pixel color information. For example, a green pixel gets color information from adjacent blue and red pixels, and so on.

CFA sensor relies on eye's sensitivity to green

Why does a CFA sensor assign twice as many pixels to green as to red or blue?

Because the eye is most sensitive to green light (figure 1). Human vision depends mostly on wavelengths in the green range to perceive fine detail and luminance resolution.

The three charts in figure 2 all have the same contrast. Notice how the green background lets you detect fine detail more easily. Most digital cameras take advantage of this fact of human vision.

By capturing relatively more green information, they can get by with much less blue and red information. Thanks to this clever solution, a mere monochrome image sensor can be used to deliver color images of high quality.

So, what's the problem?

Though it is true that our eyes are most sensitive to green luminance (sharpness and contrast) information, we also see blue and red chrominance (color) information. But the unequal treatment afforded these colors by a CFA sensor causes a disparity between the luminance resolution and chrominance resolution of the photographic images it generates.

resolution is an important key to photographic naturalism.

Unencumbered by a low-pass filter

Unique, innovative direct image sensor

Unlike CFA sensors, the image sensor in

Sigma digital cameras uses three layers of photodiodes to gather the entire red, green and blue color information of light, forming the world's one and only full color capture system. Since introducing its first-generation digital camera in 2002,

Sigma has maintained an unwavering commitment to this unique technology.

The image sensor is made of silicon. When struck by light, silicon absorbs shorter wavelengths (blue) near its surface and longer wavelengths (green, then red) at deeper levels. The direct image sensor takes advantage of this fact, using three layers of photodiodes to capture all colors of light at each pixel location. Like color film in essence, this vertical structure bypasses the need to gather different colors at different horizontal locations.

All pixels capture full RGB color

Another thing: color filter arrays are prone to false color patterns (moiré).

This problem is caused by interference between repeating patterns of fine lines in the subject and the mosaic pattern of the color filter array itself. Moiré is typically prevented by installing a low-pass filter in front of the image sensor.

A low-pass filter works by removing the higher frequencies of light that carry fine detail. This does prevent interference and, therefore moiré. But it also adversely affects resolution and image sharpness.

Facing this tradeoff, some cameras use

CFA sensors without a low-pass filter, accepting the inevitable color moiré patterns as the price to pay for a sharper image.

Sigma's direct image sensor design doesn't use color filters, so it doesn't need a low-pass filter to prevent the false colors of moiré. The direct image sensor captures the sharp image formed by the lens without losing any information. As a leading lens maker with uncompromising standards of photographic image quality,

Sigma believes the ideal capture system is one that receives full color information at each and every pixel location.

This means that a direct image sensor having 15,000,000 pixel locations is able to capture full red, green and blue color information, as is, at each pixel location. In other words, all 15,000,000 pixel locations can respond to all three primary RGB colors transmitted by the lens. There is no need to assign red, green and blue to separate pixel locations, nor is it necessary to fabricate or eliminate color information during image processing. This full color capture system is, in principle, capable of providing equally high luminance resolution and chrominance resolution.

Pure color and light: nothing added, nothing lost

In CFA sensor-equipped digital cameras, only one color is captured per pixel location. Color interpolation is required to generate a full color image from these single-color pixels. Over the past decades, color interpolation algorithms have greatly improved, so that interpolation errors are rarely a cause for concern in today's digital cameras.

Since typical photographic subjects do contain an enormous amount of color information, Sigma is convinced that removing any discrepancy between luminance resolution and chrominance

Nevertheless, light information lost in the capture process can never be perfectly reconstructed. This standard approach cannot fulfill the promise of truly natural images. In sharp contrast, Sigma's direct image sensor has no use for color interpolation and doesn't suffer from its associated problems.

Sigma's technology generates naturally faithful color images without needing to add information. This is why the ambience of the scene is so vividly captured in photos taken with a Sigma digital camera.

This reflects Sigma's policy of protecting the integrity of image information — keeping the image pure.

Image quality at its bona fide best.

Astonishing 46MP resolution

10

Do mega pixels matter?

Today's digital cameras have already reached impressive pixel counts.

The figures seem sufficient to generate high-resolution images, and even to withstand scrutiny in enlarged prints. A plausible case is often made that the mega-pixel wars are meaningless because digital cameras already have enough pixels.

The claim gains further support from an understanding that resolution is not determined by pixel count alone. In a photograph, resolution also depends on interactions among many other factors, including lens characteristics, low-pass filter response, noise reduction, and processing of contrast and sharpness parameters. By itself, elevating the pixel count doesn't necessarily lead to an appreciable improvement in picture quality.

Consider the 14MP direct image sensor used in the Sigma SD15 and

Sigma DP1/DP2. Despite having a nominal 4.6 million figure for the number of pixel locations, this sensor produces images that are widely recognized as having excellent resolution.

Where resolution and realism meet

Still, Sigma thinks raising the pixel count is desirable and necessary to achieve the most natural image rendition. In digital cameras, the limit of resolution is determined by pixel pitch. When a certain level of detail

(spatial frequency) is exceeded in a target object, the camera suddenly loses all ability to resolve it.

This phenomenon is one reason why photos that include fine detail can end up looking unnatural.

worthwhile not to win the pixel wars, and not even to make large-format prints. Rather, Sigma believes it is needed to achieve more natural photographic results.

30MP equivalent

‘emotional image quality'

As an example, say you are shooting a landscape with grass in the foreground and mountains in the background. The thin, closely spaced blades of grass are resolved correctly by the sensor in some areas, but exceed the limit of resolution in others. On the other hand, the ridges and surfaces of the mountains in the distance have a low enough spatial frequency to be resolved correctly throughout.

In other words, the foreground would appear partially blurred against a consistently sharp distant background. A human observer would register the opposite: sharply defined blades of grass nearby, and hazy mountains in the distance.

The 46MP direct image sensor of the SD1 is a breakthrough that triples the 14MP resolution of the sensor used in Sigma cameras up to now, while retaining the “emotional image quality” that is unique to a full-color capture system.

We enlarged the sensor to APS-C size (1.5x focal length equivalent), while narrowing pixel pitch, thereby dramatically raising the pixel count to 46MP (4,800 x 3,200 x 3).

This limit of resolution, which can be at odds with the human visual system, may be an unavoidable fact of physics. But Sigma believes innovation can make the problem so imperceptible that we can realistically pursue and achieve more natural image depiction. If so, we can look forward to being able to shoot images that are minimally affected by enlargement, and that retain a three-dimensional ambience even when viewed in small formats.

Further pursuit of high resolution is

The luminance resolution of this sensor is, in fact, equivalent to that of a 30MP CFA sensor as measured on the standard B&W resolution chart used in conventional digital camera resolution testing.

With outstanding chrominance resolution that is free of low-pass filtering and color interpolation,

Sigma takes a bold leap closer to the ideal, further enhancing the advantages of a direct image sensor.

In terms of technology and image quality, this represents a significant advance.

Here at last is an image sensor for all who have ever dreamed of a digital camera breakthrough that can deliver the ultimate in image quality.
