xTeleZoom extends the lossless zoom range of iPhone 7+ dual camera

Computational imaging technology increases the resolution and enables high quality zoom beyond iPhone 7+ 2x telephoto camera hardware.

February 27, 2017. Barcelona.
Today at Mobile World Congress, Almalence, the leader in computational imaging technologies announced its xTeleZoom app for the iPhone, enabling extra high quality zoom capability. Using a sophisticated computational technique, the app is able to dramatically preserve resolution and suppress the noise while zooming.

Mobile phone photography is still limited in its ability to zoom in without sacrificing resolution and image detail. While there is no practical way to create an optical zoom solution in mobile form factor constraints, the phone makers, including Apple, add an extra telephoto camera to their devices to provide good zoom quality. This approach, however, is able to provide only a limited optical zoom factor as the longer focal length lenses in mobile size constraints suffer from decreased aperture, resulting in low resolution and high noise level.

“We developed xTeleZoom because even the most advanced hardware solutions alone cannot address the need for taking high quality zoom photos”, said Eugene Panich, CEO of Almalence. “The decreasing thickness of new phone generations poses bigger challenges on the lenses ability to zoom and resolve good image quality. Software like xTeleZoom is the only practical way to break the zoom quality barrier”.

Almalence’s xTeleZoom uses computational imaging technology that enables better zoom shots from the iPhone without compromised image quality. Originally developed for professional photography it’s now available as an iPhone app to extend the high quality zoom range of the telephoto camera of the iPhone 7+. The users of the iPhone 6, iPhone 6s and iPhone 7 models without a tele camera will also benefit from higher quality zoom using the xTeleZoom app.

xTeleZoom is available on iTunes for $.99: https://itunes.apple.com/us/app/xtele-zoom/id1189050574

Almalence’s new technology makes cameras see like human eye

Have you ever noticed that you see much more details when looking at a scene by eye than when seeing a photo of the same scene? If not, it’s just because it’s too common to be noticed. Even having, physically, a lower dynamic range than a camera, human eyes see more.

Almalence Dynamic Range Optimizer optimizes the usage of dynamic range of 8-bit images to make the most of image details visible. DRO uses a technique similar to tone mapping, exploiting the peculiarities of human vision. DRO can be used either for optimal conversion of RAW images into 8-bit RGB/YUV images or for improvement of existing 8-bit images.

Almalence Dynamic Range Optimizer reveals details in highlights and shadows. Automatic processing within milliseconds.

Same data acquired by the camera, different usage of dynamic range. Left: standard image produced by the camera. Right: result of Almalence DRO processing, close to what human eye would see. Details in shadows are revealed due to optimization of dynamic range usage. Noise is not amplified.

DRO is easy-to-integrate, extremely fast solution that automatically improves the images in 100% cases and can substitute HDR in most of cases.

Comparing to existing solutions aiming to provide similar improvements of digital imaging, Almalence DRO:

  • is faster by the order of magnitude, which allows to use it in mobile devices, for both still images and video
  • provides better quality, mainly due to absence of noise amplification in shadows
  • improves both shadows and highlights
Details in shadows are revealed due to optimization of dynamic range usage. Noise is not amplified.

DRO can be integrated in ISP, camera drivers or applications.

A Better Camera: alpha testers wanted!

For years we’ve been providing you with the most advanced imaging applications for Android. Now we have fused all our applications into a single multi-purpose camera app.

Moreover, we have made this application open source so that it should be backed with the power of Android developers community!

We are excited to invite you to become an tester of a very early alpha version of the application.

Superb quality zoom with newly available Huawei Ascend P2, first tests at MWC 2013

Camera became one of the things (if not the only one) that really make the difference in modern smartphones. Among the leading OEMs such as HTC, Sony and Intel who emphasize their new advanced camera features, Huawei offers something really unique – SuperZoom feature, allowing to take high quality images when zooming in with a mobile phone camera.

We had a chance to test SuperZoom feature with Huawei Ascend P2 phone at Huawei’s stand at Mobile World Congress. In brief, it works incredibly, see the pictures below.

Comparison: SuperZoom vs normal zoom, Huawei Ascend P2

Conclusion: SuperZoom is a revolutionary technology providing zoom quality comparable to optical zoom, on mobile devices!

Almalence releases an accessible HDR tool for converting RAW into detail-rich vivid images

Your camera captures the details, HDRAW makes them visible

Tone Mapped RAW versus JPEG: JPEG has less details due to squeezing and cutting of dynamic range

The maximal dynamic range – the contrast between the brightest point and the darkest one – of a JPEG image is about 4,000 times lower than the range seen by a human eye. A camera captures several times higher dynamic range than one available with JPEG. This means that the range is either cut or squeezed in JPEG photos, therefore in high contrast scenes the details in highlights and shadows are lost, as well as the details of low-contrast objects. RAW images still contain the full dynamic range captured by the camera.

HDRAW utilizes Tone Mapping technique, allowing to preserve the details while fitting high dynamic range image into the limited dynamic range of JPEG or any other 8-bit format. Exploiting the properties of the human vision, HDRAW makes the picture and color details visible in all areas of the photo from the darkest to the brightest one.

Single-image HDR

HDRAW is a single-image HDR tool that utilizes higher dynamic range available in RAW.

RAW made easy

While usual RAW development process is a sophisticated task that requires adjusting a lot of parameters in a RAW converter, HDRAW is intended to produce rich detail images virtually in one click (ok, three clicks actually). It still allows you to adjust tone mapping parameters, but the standard presets are enough in most cases.

HDRAW.net

Along with HDRAW application we’ve launched HDRAW.net community for photo sharing, discussions, etc.

HDRAW is available at introductory price of $14.99. Registered users of PhotoAcute can use HDRAW for free – HDRAW accepts PhotoAcute 3 registration codes.

RAW converted with HDRAW versus JPEG: JPEG has less vivid colors and less details visible

Catch the very moment with our new Android application

Unlike the other cameras that take an image after you tap the shutter button, Pix Fix keeps taking the images until you tap the button.

So, the meaning of the Button is now “Stop! That’s a wrap!” instead of “That’s the moment, ooops I’ve missed it”.

After clicking the shutter button you have a series of photos taken before the click. You can then pick the photos where the moment is captured or save the whole series.

Pix Fix is available at introductory price on Google Play. Get it now!
