In a video signal transmitting device, a basic image generation unit extracts, for each of the color signal component, pixels constituting a frame of the color signal component at a uniform interval two-dimensionally and two-dimensionally arranges the extracted pixels in a prescribed arrangement to generate a prescribed number of color signal basic images. A basic stream generation unit extracts, for each of the color signal basic images, pixels of the color signal basic image generated by the basic image generation unit in a prescribed sequence to generate a basic stream. A link signal generation unit synthesizes a prescribed number of basic streams in the same or different color signal components generated by the basic stream generation unit, encodes bit-length units of the synthesized basic streams to a different bit length, and generates a link signal having a prescribed speed.

Disclosed are an imaging device and a display device which both have a simple structure without any need of an image conversion. The imaging device includes a lens component group including multiple lens component systems, each of which focuses incident light from the object, thereby creating a non-inverted image of the object, the lens component systems being arranged in an array form and on the same level, and an image capturing mechanism for picking up the created image. In addition, each of the lens component systems includes an afocal optical system and an image-forming system. The afocal optical system includes at least one optical element for inverting an externally incident light ray relative to its optical axis and outputting the light ray. The optical element has uniform refractive index. The image-forming system includes at least one optical element having uniform refractive index throughout its interior.

Imaging device and display device

A three-dimensional image optical system including at least an elementary image optical subsystem constructed with plural afocal optical elements which include the first and the second optical components, wherein the plural afocal optical elements are aligned in a planar arrangement. The variety of the focal length to satisfy the afocal property is realized with the combination of the first optical components and the second optical components, that results in to provide the flexibility of the depth magnification, by which a remote observation is possible.

Three-dimensional image optical system

High resolution vertical and horizontal components of a high definition video signal are combined with a standard broadcast system video signal, such as the NTSC system, in which high frequency horizontal resolution components are sampled and used to modulate at least a first sub-carrier signal. The first sub-carrier is frequency interleaved onto the standard broadcast signal. Vertical high resolution components are time compressed and time division multiplexed onto top and bottom portions of the standard broadcast signal. The modified broadcast signal can be decoded by a standard receiver to display a standard resolution video image, while receivers designed to decode the modified signal can time division demultiplex the vertical high resolution components and demodulate the horizontal high resolution components, combine these components with the standard components, and generate a high definition video image.

Receiver and channel compatible encoding/decoding system for high

A multiple sub-sampling encoding/decoding system performing interfield and interframe offset sub-sampling of a broad bandwidth television signal. The system compresses the television signal to fit, for example, to the transmission bandwidth of the standard television systems, compensates the transmission characteristics, and achieves the optimal frequency allocation of the modulated transmission signal.
