P1 Updating of Scrambling Scheme
We are studying various ways of updating broadcasting scrambling schemes to maintain their security. The updating method shown here enables migration to a new scheme without affecting the TV sets that use the existing scheme. It supports both new and existing TV sets during the transition period by allowing the use of both schemes.
P2 Emotional Speech Conversion Technique for Neutral Recorded Speech
We are researching technologies that will make it easier to add complex production effects to recorded and synthesized speech. We have developed a technology to add emotional expressions to speech read by a speaker by processing it with emotional expressions (such as delight, anger, and sorrow) of a different speaker.
P3 Haptic Technology to Convey Shape and Hardness of 3D Objects
To enable services that remotely convey the sense of touch, we have been studying a haptic presentation technology that can reproduce the shape and hardness of an object from digital data. Shown here are the results of an evaluation of the relationship between the number of stimulus points on the fingertip and the ease of conveying an object’s shape, as well as a haptic presentation device we prototyped.
P4 Higher-resolution Image Enhances Viewer’s Depth Sensation
8K Super Hi-Vision video can give viewers a stronger depth sensation than the current Hi-Vision. To look into the cause, we conducted a psychological experiment using figures with various shades to express a three-dimensional shape. The results are reported here.
P5 Operation Principle of New Magnetic Nanowire Memory
With the goal of realizing a high-speed, compact recording device, we are developing a recording device with no moving parts that utilizes the motion of nano-sized magnetic domains on magnetic nanowires. Shown here are the technologies used in the operation principle of this recording device: magnetic domain formation (recording), magnetic domain driving using currents, and magnetization status detection (reproduction).
P6 Fabrication Technology for Flexible OLED Displays Using High-mobility Oxide Semiconductor ITZO
With the goal of realizing large, sheet-type 8K SHV displays, we are researching technology for fabricating flexible displays that have high-mobility ITZO-TFTs with a back-channel-etched structure, which is effective for a large screen with many pixels, and inverted OLEDs, which extend the lifetime of the display.
P7 Field Emitter Array Image Sensor with HARP Film
To build a compact Hi-Vision camera with extremely high sensitivity, we are researching imaging devices that combine a field emitter array with high-sensitivity HARP photoconductive film. Shown here are the electrostatic-focusing field-emitter array and the active-matrix drive circuit technology that are required for this device to support Hi-Vision.
P8 Solid-state Image Sensor Overlaid with Photoelectric Conversion Layer
To improve the sensitivity of 8K Super Hi-Vision cameras, we are researching solid-state image sensors overlaid with a photoelectric conversion layer able to multiply electric charges simply by applying a low voltage. The results of our attempts to improve the characteristics of the photoelectric conversion layers are reported here.
P9 Pixel-parallel Processing Three-dimensional Integrated Imaging Device - Toward future cameras for capturing three-dimensional images -
We are studying a three-dimensional integrated imaging device with pixel-parallel processing that combines ultra-high-definition images with a high frame rate and that will contribute to the development of future cameras for capturing three-dimensional images. Shown here are the architecture of the signal processing circuit, the technology to manufacture the device, and the characteristics of the prototype device.
