A new multi-luminance-level subfield method is proposed to improve the low gray-level color reproducibility of a plasma display panel. Multi-luminance levels can be expressed per sustain pulse in low gray scale by applying the different auxiliary pulses in the same sustain-pulse subfields, thereby suppressing the low gray-level contour.

The plasma display panel (PDP) is one of the best solutions for TV sets, but its retail price remains higher than that of CRTs. This paper proposes a low-cost PDP data dispatcher which focuses on converting the image signal inputs into the PDP display format and reducing the numbers of components as well as the cost used in the dispatcher module at the same time.

A new driving-scheme is used for balancing white colors of plasma display panel-television (PDP-TV) by independent luminance control of the red, green and blue colors. White colors of eight subfields can be clustered within a region, which is not resolvable in terms of visual perception. View full abstract»

In order to realize high-brightness and high-quality pictures for an ultra portable LCOS (liquid crystal on silicon) projector, a high-performance optical system comprising an illumination system with PCU (polarization converter unit), a new color-management unit with a polarized system and a small-size LCOS panel has been developed.

We present method that uses digital video watermarking as a real-time authenticator in a video stream. The proposed scheme uses the Hadamard transform as the spreading transform for the key, hence very fast coding and decoding of the the imperceptible watermark is realized. This in turn, can serve to verify the source of a digital frame in real-time. View full abstract»

This paper proposes a new watermarking method, which uses motion analysis to allocate watermarks where they will be less perceptible and thus improves their transparency. The proposed method would be most effective when incorporated into MPEG encoders and could be widely used in consumer electronics. View full abstract»

This paper presents a blind data hiding technique in still images. The cover image is de-correlated by using the key. The error control channel coding is introduced into the data hiding scheme. The message encrypted is encoded with a turbo coder. The one-way hash function is used in the embedding process. The algorithm for hiding bit selection is proposed and an experimental implementation of the ... View full abstract»

This paper proposes an invertible semi-fragile video watermarking algorithm using a hash function to authenticate the video contents. It can protect the video content from malicious manipulations and detect the modified part of the video. Also the proposed algorithm has the invertible property, which allows us to get the original video data back if they are authentic. View full abstract»

The ITEA (Information Technology for European Advancement, an eight year funding program labeled by EUREKA) project EUROPA (End User Resident Open Platform Architecture) started in October 1999 for a duration of 2.5 years in the first call of the ITEA program. The project aims at the definition of a high-end set-top-box (StB) reference architecture with extended functionality to enable next-genera... View full abstract»

We developed the ARIB-compliant HDTV-PC and used it for experimentation of unified applications by both digital broadcasting and broadband communication. With the rich viewing of HD video and synchronized interactive data services, a HDTV-PC solution is a more compelling one than each of the digital DTV and broadband PC. By combining the rich viewing by HD video and abundant information from the I... View full abstract»

General purpose operating systems do not provide a quality of service (QoS) guarantee for processing isochronous A/V data streams. The TrueTime software architecture provides a model for guaranteed processing of isochronous streams. The TrueTime architecture integrates with an OS kernel to exploit the streaming nature of isochronous data streams. View full abstract»

Future consumer terminals will be based on programmable platforms instead of dedicated hardware. Novel 'scalable video algorithm' (SVA) software modules provide trade-offs between resource usage and quality of the output signal. SVAs together with a strategy manager (SM) and a quality-of-service resource manager (QoS-RM) aim for robust and cost-effective media processing in software on programmabl... View full abstract»

The ever increasing complexity of automotive entertainment and information systems has necessitated a universal communication network for vehicles. Intelligent transportation systems (ITS) initiatives have focused on road and rail infrastructure, to enable telematics communications between roadway/railway, vehicles and public agencies, primarily to provide enhanced public services, such as traffic...

There is a need to provide a mobile network architecture that delivers quality concurrent access to personalized information and services - whether distributed by the broadcast media, over the Internet or via the telephone. Current information appliances either lack adequate display capabilities (e.g. cellular phones) or mobility (e.g. WebTV). Nevertheless, in the near future, the volume of inform...

Car navigation systems have been evolving since the first type GPS navigation system was launched. The increasing amount of map data and related information have been stored on CD-ROM disks and DVD-ROM disks. In the latest HDD navigation system, the map data is stored on HDD, so the driver can operate navigation and the passenger in the rear seats can enjoy watching DVD-video at the same time. We ...

Automotive navigation systems these days have access to processors with large computing power, inertial sensors, Global Positioning System (GPS) receiver, radio data service-traffic messaging channel (RDS-TMC) receiver and accurate digital map database. This enables the development of various driver assistance systems that provide greater functionality than conventional automotive navigation syste... View full abstract»

We have developed a new readout circuit for highly sensitive CMOS image sensors. The circuit makes it possible to obtain high signal-to-noise ratio (S/N) by effectively transferring signal charges accumulated in the photo-diode (PD) to a smaller capacitance. We fabricated and tested a CMOS image sensor with the readout circuit, and confirmed that it has higher sensitivity than conventional passive... View full abstract»

Non-integrating CMOS image sensors have a higher dynamic range than alternative designs, making them more suitable for automotive applications. Unfortunately, gain and offset non-uniformities in the photosensors and active elements on the focal plane generate fixed-pattern noise in the received image, limiting the resolution and sensitivity of the vision system. We present a solution based on an a... View full abstract»

This paper presents a method to optimize the visual quality of JPEG2000-compressed images using an adaptive approach to assign more bits to regions in which errors are more visible, maintaining the global bit-rate unchanged. View full abstract»

This document describes the technical details of an algorithm able to enhance digital image resolution. The main idea of this approach is the use of "uncertainty" in pixel reconstruction and an auto-iterative approach for error correction. View full abstract»

We developed three new technologies of color reappearance, resolution and dynamic range for a high quality image. We improved the digital still camera using the developed new technology. View full abstract»

We present elastic storage, a storage method that offers users of digital still image cameras more flexibility and a more efficient use of storage capacity than currently available. The implementation exploits the flexibility offered by new scalable image compression methods, such as the recently standardized JPEG2000. These make the storage space "elastic", storing a continuously variable number ... View full abstract»

Interconnectivity of digital cameras with other devices seems to be one of the main concerns of consumers and digital camera manufacturers. Interconnectivity features in digital cameras provide better usage of digital cameras. Moreover, with adequate application layer software, the digital photographs could go directly from camera to the desired target: disk, printers, web sites or web prints, usi... View full abstract»
