摘要:
A liquid crystal display unit has a transmissive liquid crystal plate having a number of pixels arranged on a two-dimensional basis, on which an image is formed, and a light source unit emitting beams of light of a plurality of luminescent colors for irradiating said liquid crystal plate from back. An interface circuit receives an image signal representative of a color image to sequentially form on said liquid crystal plate a plurality of separation images in which the color image is separated in association with the plurality of luminescent colors of said light source unit. The interface circuit causes said light source unit to flash with a luminescent color associated with a separation image formed on said liquid crystal plate in synchronism with a sequential formation of the separation images onto said liquid crystal plate. Beams of light emanated from the light source unit and transmitted through the liquid crystal plate reproduce an image.

A solid-state imaging device constructed according to the TSL system having a plurality of photodiodes arrayed in matrix form so as to serve as a group of pixels, a vertical selection gate line extending from a vertical scanning circuit, a horizontal selection gate line extending from a horizontal scanning circuit, and a signal read line. A projection made of an impurity layer identical to that of the photodiodes is formed at an end of each of the photodiodes. A first switching transistor is formed by interconnecting the vertical selection gate line made of a polysilicon layer so as to cross over an upper surface of each of the projections. A second switching transistor is formed by laminating a gate portion made of a polysilicon layer on the other upper surface of each of the projections. Horizontal selection gate lines are formed by connecting between the vertically arrayed gate portions and an interconnection made of a conductor layer such as an aluminum layer insulatively laminated above the polysilicon layer. Signal read lines are formed by a conductive layer fabricated by a process identical to that of the conductive layer, and each signal read line is interconnected so that the upper surface of the projection and the upper surfaces of the first and second switching transistors are shielded thereby, and that the signal read line does not come in contact with the conductive layer forming the horizontal selection gate line.

A solid-state imaging device has a single plate structure and is capable of imaging of visible light and infrared light. While imaging of the visible light and the infrared light is performed by the imaging device every one-frame scanning period, an IR pulse is emitted, every other one-frame scanning period, to a space to be shot. A visible-light image is produced every one-frame scanning period. A range image from which influence to be caused by infrared component of the ambient light is removed is produced every other one-frame scanning period by subtracting an IR pixel image (S2IR), which is obtained by imaging of non-emission time of the IR pulse, from an IR pixel signal (S1IR), which is obtained by imaging of emission time of the IR pulse.

A bi-directional shift register capable of transferring bit data in either a forward or reverse direction. The shift register includes multiple transfer elements (e.g., flip-flop circuits) cascaded together which provide synchronous transfer of the bit data from one stage to an adjacent stage in either direction. The shift register further includes two switching circuits for electrically connecting an input terminal of one transfer element to an output terminal of the adjacent transfer element. The first switching circuit is enabled to cause the transfer of the bit data in the forward direction, and the second switching circuit is enabled to cause the transfer of the bit data in the reverse direction.

The position of a principal image within a frame is designated manually or in association with the operation of the automatic focussing mechanism. The position information of the principal image is recorded on a photographic film when a subject is photographed. In obtaining a photoprint, the position information is read from the frame to be printed, and the principal image within the frame is identified. A characteristic value used for calculating an exposure amount is derived from the identified principal image, so as to execute an exposure control emphasizing the principal image.

摘要:
A light beam scanning system comprises a wave guide formed of a material allowing propagation of surface acoustic waves therethrough, and a means for generating the surface acoustic waves in the wave guide so that they advance along an optical path of light incident upon the wave guide, and a drive circuit for periodically applying a pulsewise voltage to the surface acoustic wave generating means. The wave guided inside of the wave guide is emitted out of the wave guide at the section where the surface acoustic waves are present by a coupling action of a grating generated by the surface acoustic waves with the guided wave.
