We developed a new video footage management system, called "Video Bank", which automatically adds useful metadata, for video retrieval and compositing purposes, as the footage is being stored in the system. For compositing, the system interactively extracts the desired video object area from the footage.
It is important to measure the spatial resolution characteristics of 4K/8K cameras in order to fully exploit their capabilities, which should be well in excess of current high-definition (2K) broadcast cameras. The conventional evaluation methods measure the characteristics at a specific spatial frequency, either in the vertical or horizontal direction of the image. We have developed a new method that measures camera resolution characteristics at all frequencies in all directions in a single measurement.
In order to create sound for 8K Super High-Vision in accordance with the sound engineer's intentions, we are studying a method where the sound of each 22.2 channel is not controlled independently. Here, we illustrate the relationship between spatial impression and the reverberation parameters in 22.2 multichannel sound.
News reporting in Japan features many expressions that are not used in everyday conversations. We have studied how well these expressions are understood by international residents in an effort to deliver easy-to-understand news in Japanese to our foreign audience.
We are studying a method that estimates the mental states of viewers while they are watching a program by analyzing their brain activities. By using machine learning, this method can estimate the viewer's "readiness to laugh" by automatically extracting a characteristic pattern from the measured brain activity.
We are studying optical devices for future 3D displays. We have developed a device consisting sub-micron-sized dielectric cylinders that has capability of deflecting a light beam in controlled direction.
Looking beyond 8K super-high definition television, we are studying a imaging device with a 3D structure that can meet the ultra-high resolution and high-frame rate requirements of future systems. The device has a digital processing circuit formed beneath the photodetector and reads out signals from all pixels in parallel.
We are studying organic films that convert each of the 3 primary colors of light into electronic signals and an organic image sensor made by stacking organic films and transparent readout circuits. The continuously stacked technology aims to improve the resolution image sensors by eliminating defocusing for each color.
Time-shift viewing allows you to watch past programs anytime you want. We are studying ways to provide this broadcasting service of the future. Viewing experiments of the service where viewers can zap in the time direction through several years' worth of past television programs were conducted, and the findings on the viewing behaviors are reported here.
