摘要： A projection-type video display in which the entire input video signal is first digitally corrected through digital gamma correction. Then, a subset of the corrected video signal is corrected again through analogue correction techniques.

The result is a more accurate gamma correction which is also less expensive than conventional, purely digital gamma correction systems. Another feature is the inclusion of three liquid crystal light valves, each having have a plurality of pixels arranged in the matrix and identical shift registers in such a way that pixels of one scanning line are driven selectively and sequentially from the same horizontal direction according to a given set of video signals, a memory where at least video signals for pixels of one scanning line are written and stored, a first drive controller for outputting video signals of one scanning line from memory in the order in which the video signals were written and supplying the video signals to pixels of a scanning line in at least one of light valves, and a second drive controller for outputting video signals of one scanning line from memory in a reverse order in which video signals were written thereto for supplying another light valve. Also disclosed is recognition unit for recognizing different types of input video signal format systems and a write controller for controlling the way of writing input video signals of each scanning line into pixels of horizontal scanning lines in the light valves based on different type of input video signal format system.

摘要： To provide an image display apparatus in which, even if pixel data is phase-expanded, the influence of differences in circuit characteristic can be dispersed between frames. The apparatus has a phase expansion circuit 380 to which are input a first video signal A1 having pixel data for driving pixels with positive voltages and a second video signal A2 having pixel data for driving pixels with negative voltages. The phase expansion circuit 380 forms six phase-expanded signals V1 to V6 from the first and second video signals A1 and A2. The phase-expanded signals are expanded into pixel data by extending the data length of items of the pixel data corresponding to some of the pixels periodically selected. The phase expansion circuit 380 outputs the phase-expanded signals to phase-expanded signal output lines in parallel with each other. The apparatus also has a connection change circuit 390 for changing connections between six phase-expanded signal output lines 388a to 388f and six signal supply lines 132a to 132f. Change of the order of expansion into six phase-expanded signals V1 to V6 by the phase expansion means and change of the combination of connections changed by the connection change circuit 390 while being linked to the expansion order are controlled by a timing generation circuit block 200. This timing generation circuit block 220 performs change control so that a expansion order first set with respect to the preceding frame is changed to a different expansion order in synchronization with vertical synchronization.

摘要： The present invention provides a technology that enables projection images to be overlaid with embellishment effects without depending on the capabilities of the image supply apparatus. A projection display apparatus that projects images onto a screen responsive to given image data, comprises: an embellishment effect memory for storing embellishment effect data representing an embellishment effect image that can be used to embellish an arbitrary image; an image embellishment section that generates embellished image data by overlaying an original image represented by the given image data and the embellishment effect image; a light modulation unit that is driven responsive to the embellished image data pixel by pixel; and an optical system for projecting onto the screen the embellished image obtained by the light modulation unit. A projection display apparatus superimposes the embellishment effect on the projected image without having to rely on the capabilities of an image supply apparatus.

摘要： A light-source lamp unit includes a light-source lamp unit detachably mounted, and a CPU constituting a drive and controller for the light-source lamp unit. The CPU senses lamp information obtained by a lamp-information storing block in the light-source lamp unit, pertaining to a lamp power rating, lamp life and whether a lamp is new or not, and starts counting operation time when the lamp is lit. The CPU compares the lamp life sensed and the operation time count, and forces the lamp to extinguish when the life of the light-source lamp expires. Prior to this action, the CPU gives a warning display before the life expiration of the lamp by a fixed duration of time, to warn that lamp replacement is needed. Because the lamp-information storing block in the light-source lamp unit stores the information about the lamp type and characteristics of the lamp, the light-source device can properly drive the lamp to light it and determine the lamp life even when a light-source lamp unit of a different type is used.
