In the case of subjective quality assessment on high resolution video, an observer has to vote by viewing the limited area due to the short viewing distance. In order to analyze the effect of the viewing condition on the evaluation result, we conducted two experiments: First, eye tracking data was acquired during viewing 4K video sequences. Second, viewing area was divided into two regions, and observer evaluated the subjective quality of the divided region.

We have developed a rear-projection display system, which has various screen shapes for automobiles to fit the shapes to the design in a cabin. Its projection optical system is applicable to various screen shapes without redesigning the system. In this paper, a signal processing to correct its distortion is described.

For mobile(e-book) applications, we fabricated a prototype reflective liquid-crystal display panel with c-axis-aligned crystal indium-gallium-zinc oxide field-effect transistors. The panel shows a very small reflectance change of less than 1.22% in low-frequency driving, enabling low-frequency driving where flickers are barely perceived by human eyes.

The silicon carbide filter is used to suppress the particulate matter emitted by diesel vehicle. However performance of the filter is changed by deposition of particulate matter. Therefore it is necessary to observe the inside of the filter to develop the filter optimally. This work proposes method of 3D-Neutron Computed Tomography using I-MAP and TV method to observe the inside of the silicon carbide filter. We compared the proposed method with the conventional method by simulation.

Applying a conventional image inpainting method only once does not always generate plausible textures, and this problem is usually solved by repeatedly applying image inpainting with manual reselection of failure regions. This paper proposes a method that automatically detects failure regions in a resulting image using a convolutional neural network.

We propose a method for inpainting images by an extrapolative filter which outputs at each damaged (or missing)
pixel a weighted average of extrapolated pixel values from neighboring undamaged and inpainted pixels. Experimental
results show that the proposed method can inpaint damaged regions with smaller blur than conventional methods.

We have proposed new storage devices utilizing current-driven domain wall motion along magnetic nanowire, in order to achieve ultra-high data transfer rate. From simulation for formation of magnetic domains in magnetic nanowire medium with a soft magnetic underlayer(SUL), it was shown that magnetic domain is formed stably when wide SUL is located under magnetic nanowire. Furthermore the use of SUL is an effective method of achieving a high speed recording.

Imaging devices using fish-eye lens have been in demand recently for surveillance or on-vehicle, because of wide-angle of view. However, fish-eye images need distortion correction to grasp shape or position of objects precisely. We studied high-precision distortion correction method for fish-eye image, using index value combined with height from camera and distance from optical axis.

Using our method, we achieved highly efficient and low computation encoding.

In this method, a 3D position of each representative color in a RGB color space is directly predicted from neighboring pels. This paper compares three kinds of the prediction techniques from the viewpoint of trade-off between prediction efficiency and the required side information.

A new image reconstruction method using equi-spaced under-sampled signal is proposed. Our method has an advantage over standard compressed sensing in that the quality of the image does not depend on the randomness of the sampling trajectory. Simulation studies and experiments show that the proposed method using the Curvelet transform has almost the same peak signal-to-noise ratio as that of a compressed sensing reconstruction.
