    摘要: A projection display uses a light modulating device to modulate, in accordance with image data, light radiated from a light source, project the modulated light onto a screen, and display an image. The projection display separates a unit of time configuring the image data into an effective light time when the light modulating device can express the light as an image on the screen and an ineffective light time when the light modulating device cannot express the light as an image on the screen. The projection display increases the power supplied to the light source during the effective light time over the power supplied to the light source during the ineffective light time.

    摘要: An image signal representing consecutive video frames is resampled, using different sampling phases so that different subsets of pixels are taken from each frame in a consecutive set of frames. The resulting set of resampled frames is combined into a single frame and transferred to an image display unit that divides the single frame into subframes and displays the subframes sequentially with different pixel shifts. Each pixel in each subframe is displayed at its correct spatial and temporal position. Although the resampling process greatly reduces the pixel data transfer rate, the image display unit can reproduce still images without loss of definition and moving images without motion blur.

    摘要: There is disclosed a display device using a color wheel having a color filter Cw, in addition to normal color filters corresponding to the three primary colors. The filter Cw has almost flat spectral transmission characteristics. Brightness information included in a color image signal is quantized with (n+m) bits. Information corresponding to the lower-order n bits is displayed by light transmitted through the filter Cw. Information corresponding to the upper-order n bits is displayed by light transmitted through the normal color filters. Only brightness information to which the human eye is visually sensitive is reproduced by the filter Cw having a lower transmissivity. This can eliminate a lack of the number of gray levels due to a constraint on the minimum switching speed of a light valve. Furthermore, the brightness little deteriorates.

    摘要: A gamma correction circuit has a data group generator which stores first to n-th gamma correction tables, receives first to n-th gains, and adjusts a level of the input signal using the first to n-th gamma correction tables and the first to n-th gains, thereby producing a gamma-corrected data group including first to n-th gamma-corrected data. The circuit also has a gamma characteristic controller which loads the first to n-th gains into the data group generator, a signal level discriminator which outputs a discrimination signal based on the level of the input signal, the first to n-th gamma correction tables, and the first to n-th gains, and an output selector which selects from among the first to n-th gamma-corrected data on the basis of a value of the discrimination signal, thereby producing the gamma-corrected output signal.
