Exclaim making mobile video sharing a Snap

Mobile photo sharing application provider Exclaim Mobility says its new Snap TV enables users to view and share mobile photos easily and in high quality through Internet-connected televisions.

“By leveraging connected TVs as the next step for viewing and sharing user-generated content, we have created an exciting new service for today’s connected user,” the company says.

muvee brings its HD video editing to Android

muvee’s Device Solutions Group released a suite of core technology stacks that enable basic editing of HD video on Android mobile phones. Muvee says its technology uses “novel software techniques to accomplish all the basic video editing functions in a fraction of the time usually needed,” as muvee’s solution is able to make changes to a compressed file.

The company says in the six years since video recording has been available on mobile devices, mobile video recording resolution has increased 150 times — yet the CPU has only increased by less than 10 fold. In 2004, the Nokia 7610 was able to capture video at sub-QCIF resolution (128 by 96 pixels at 15 frames per second) and it ran on a 123MHz chip. Today, HTC’s Desire HD captures video at 720P (1280 by 720 at 30 frames per second) on a CPU just 9 times faster. The computational power now required of today’s mobile phones to manipulate such huge and highly compressed video files have outpaced the advancement of CPUs multiple times over. Even with dual core CPU and GPUs for mobile phones, computational advancement is still expected to lag that of video resolution needs as 3D dual HD streams are enabled on mobile devices, muvee says.

Consumers share videos on social media networks, but many clips need basic editing, such as trimming, reducing background noise, adding a music track, or a personal message as a voice over. “Such simple and basic operations would take too long to process on a mobile phone using traditional methods,” the company concludes. “We don’t believe the majority of consumers will necessarily want to make a Hollywood blockbuster on their phones, but they will demand simple useful editing functions.”

The company’s suite of tools is available for license.

muvee says it established its Device Solutions Group in 2004, and released the first video editing application on Symbian mobile phones for Nokia.

NEC cancels lens zooming noise

NEC says its new noise suppression technologies record the sound of a zoom motor in a digital camera, and then subtract that noise from video as it is captured. The tech is now in Casio’s EX-ZR10.

NEC says expensive motors with limited speed and filters that prevent the passage of noise frequencies were adopted in conventional digital cameras to minimize noise levels while shooting video. This gave rise to a number of problems that include a camera’s lack of ability to take fast-moving sports footage, and sound distortion due to filters that suppress ambient sound. NEC says its new technologies resolve these problems.

“Conventionally, the sound generated by lens drivers for digital cameras in movie mode is recorded as noise by microphones,” the company says. “These new technologies suppress noise through a method that records and saves the core characteristics of sounds created by a camera lens’ driving mechanisms, then subtracts this information from signals that are recorded by microphones. Furthermore, these technologies automatically adapt to lens and microphone characteristics among different products, which eliminates the need for customized product adjustment.”

It also preserves ambient environmental sound, while only suppressing the noise generated by a camera’s motor, NEC claims.

DSLR Camera Remote improved for iPad

onOne Software has redesigned its application for remotely controlling select Canon and Nikon SLRs with Apple iOS devices.

The $50 DSLR Camera Remote HD is made for the iPad, and includes a new interface with image thumbnails and larger previews, in addition to faster access to options like the intervalometer and auto bracketing, the company says.

Also new is a Video mode in which the user can start and stop video recording on supported cameras, and remotely monitor video on the iPad.

The original $20 DSLR Camera Remote runs on the iPhone or iPod Touch; it now adds support for the Canon 60D and the Nikon D7000.

A free version allows photographers to remotely fire their camera.

Both iOS apps require another application run on a WiFi enabled Mac or Windows computer, to communicate between the iOS device and the supported SLRs, connected via USB or Firewire to a computer.

Scalado develops HDR image capture for TI OMAP 4 platform

Mobile imaging technologies provider Scalado says “there is no difference between a digital still camera, a mobile phone, or any other image capturing device. Ultimately, the end user is the most important player here, and therefore has the right to have the same user experience on any device.”

That extends to even formerly high-end features such as instant high dynamic range imaging, the company says, which can  “create stunning images” by automatically taking multiple photos at different exposure settings and then processing all of the best elements of each shot into a single image with perfectly balanced lighting.

The mobile HDR imaging will run on OMAP 4 processors from Texas Instruments. With TI, Scalado says it will “make it simple for handset manufacturers to easily integrate advanced, fully-optimized imaging applications such as instant full-resolution image handling, zero shutter lag, burst-mode image capturing, HDR imaging, 3D capturing, and instant zoom/pan at the moment the image is captured.”

Scalado also announced a new camera framework for Qualcomm’s MSM8x60 dual-core processor, saying it will enable on a mobile device such next-generation image capture techniques the “Rewind” application which picks and chooses the best faces from different versions of a group photo to create a single perfect shot.

More than 600 million mobile phone handsets now feature Scalado software, the company says. Scalado is headquartered in Lund, Sweden.
