Limited-edition camera commemorates 10th anniversary of Japanese vocaloid pop star

Ricoh Imaging Americas Corporation today announced the North American availability of a special, Hatsune Miku version of the Ricoh Theta SC camera.

The Ricoh Theta SC Type Hatsune Miku, which incorporates the same tech specs as the regular Theta SC version, features an illustration of Hatsune Miku on a blue-green-colored camera body—her signature color scheme—as well as a pink-illuminated power button. When the shutter button is pressed to capture a 360-degree image, the camera emits a custom Hatsune Miku sound, developed by Crypton Future Media. With the dedicated Ricoh Theta Type Hatsune Miku application for iOS and Android devices, users can overlay a three-dimensional image of Hatsune Miku on their 360-degree photos. The app includes 55 different poses, including Snow Miku, a winter character whose outfits are determined by annual design competitions.

The Ricoh Theta Hatsune Miku exclusive editing application can only be used with this Theta model.

The Ricoh Theta SC Type Hatsune Miku package includes a dog-tag key holder printed with the camera serial number (up to 3,939), and blue-green colored 100-percent wool case by Japanese artisan crafts company, Abitax. Both the dog-tag key holder and packaging feature an exclusive illustration of Hatsune Miku created by well-known Japanese artist, fuzichoco.

The RICOH THETA V is the new top of the range model in the 360° “RICOH THETA” camera series.

Since the RICOH THETA was first launched in 2013 as the world’s first 360° single shot camera*1, this exceptional imaging tool has been used to capture exciting and unique fully-spherical images in a variety of situations. The 360° visual space has defied the conventions of traditional photography and allowed users to capture their entire surrounding in one image. These can even be shared with others using a VR headset, allowing them be fully immersed in the scene, as though they were actually with there.

The rapid growth of the virtual reality (VR) market, the expansion of SNS (Social Networking Services) supporting 360° and the ever-increasing demand from the B2B sector, means that the opportunities to utilize the extensive capabilities of THETA are expected to expand further in the near future.

The RICOH THETA V has a compact, lightweight body, so it’s portable enough to take anywhere, anytime. Featuring the sleek design and handling THETA users have come to expect, it takes the 360° photo and video experience to a whole new level.  It’s packed full of performance-enhancing features, but some striking additions to its armory, put this device at the cutting edge of 360° innovation.

Furthermore, it achieves high-speed transfer that can comfortably exchange large volumes of data, high sound quality recording compatible with 360° spatial audio, and shoot equivalent 360° 4K video. The camera can also connect to a Smartphone or tablet using either Bluetooth or Wi-Fi, for flexible operation. In addition, the Ricoh Theta V features an open source Android operating system, allowing for future performance enhancements through firmware updates, whilst also opening up the platform to even more developers

*1. As a mass-produced consumer product capable of capturing the scene around, above and below the device in a fully spherical image (as of October, 2013, based on Ricoh research).
