CONFERENCE PROCEEDINGS FREE ACCESSIt is inevitable to maintain healthiness of oral environment for that of the whole body. To observe the condition of gums, a digital dental mirror, which can measure three-dimensional shape, oxygen saturation map, scattering map, glycogen map, and so on from a single compound-eye image, is developed. The dental mirror is based on a 3×3-eye compact compound-eye called TOMBO (thin observation module by bound optics), and is equipped with visible and near-infrared illumination, band-pass, and polarization filters. Three-dimensional shape is measured with the multi-baseline stereo method.View full abstractDownload PDF (8234K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe conducted a study on mirror array layout to extend fields of view of the virtual cameras for capturing multi-viewpoint images by using a mirror array. We set the constraints that the mirrors are placed between the camera and the subject and that all the mirrors are placed in a line. We made it possible to examine a suitable mirror array layout by making a simulation program to visualize the fields of view. We thought of four cases; all lines of sight are parallel, all lines of sight cross at a certain point of the object, multiple mirrors are used to obtain a wide view angle, and each virtual camera looks at a different point of the object. As a result, we found the case that each virtual camera looks at a different point of the object is effective.View full abstractDownload PDF (5973K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe propose a ultra-high-speed CMOS image sensor based on the multi-aperture structure. Every aperture is operated with an independent shutter pattern and accumulates temporally-multiplexed signals in pixel. After that, temporally-resolved ultra-high-speed images are reproduced by solving an inverse problem using the given shutter patterns and a captured multi-aperture image. The time resolution is defined only by on-stage charge transfer time and the clock skew between the apertures. Therefore, we believe that the proposed method realizes the fastest frame rate.View full abstractDownload PDF (3543K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe developed a combined sensor that can obtain the information for handling robot employing compound eye camera. Proximity sensing is based on the stereo images. Tactile information is obtaind through the method known as a light conductive plate. We verified the performance of the improved version of the sensor device consisting of the minituarized compound eye camera.View full abstractDownload PDF (7998K) -

CONFERENCE PROCEEDINGS FREE ACCESSWith the performance increase of image sensors, the range of possible applications has become wide. Following that, the required performance of image sensors has also become diverse. In addition, the sensing technology of image capturing that assumes subsequent processing is getting a lot more attention lately. Considering such a situation, in this paper I discuss performance of image sensors and new image sensing technologies that will be realizable and will be required from the public in the next decade.View full abstractDownload PDF (593K) -

CONFERENCE PROCEEDINGS FREE ACCESSThis paper presents a system that performs real-time super-resolved free-viewpoint image synthesis, in which, from a given set of low-resolution multi-view images captured by a camera array, a free-viewpoint image is synthesized with a higher resolution in real-time. The process of the synthesis consists of two steps: depth estimation with a modified semi-global stereo matching, and reconstruction-based super-resolution. We implemented this process in graphics processor unit (GPU) for speeding up. Our system is capable of synthesizing a high-resolution (320×240 pixels) free-viewpoint image from 9-view low-resolution (160×120 pixels) around 40 ms.View full abstractDownload PDF (13102K) -

CONFERENCE PROCEEDINGS FREE ACCESSThough the main purpose of digital cameras is to record and display images, they are also devices with excellent spatial and temporal resolutions. We consider interface and sensing technologies as essential components for realizing human-centric ICT, and are working on several novel technologies utilizing digital cameras. In this paper, we introduce our gaze detection technology, a next-gen UI "FingerLink" to manipulate objects intuitively, a heart rate monitoring system using facial images, and a smartphone-based skin condition measurement system "Hada-memory (Skin memory)".View full abstractDownload PDF (7288K) -

CONFERENCE PROCEEDINGS FREE ACCESSThis paper explains a new technical concept named Roboptics based on high-speed optical devices. A high-speed liquid lens named Dynamorph Lens and a high-speed optical gaze controller named Saccade Mirror will be described as representatives of high-speed optical devices. Furthermore, various application of the Roboptics, such as 1ms auto pan-tilt, arbitrarily focused video synthesis, 3D motion estimation, and dynamic projection mapping named Lumipen, will be explained to discuss the validity of the concept.View full abstractDownload PDF (15422K) -
