摘要： When an input component image signal is inputted in a signal processing step, a high-frequency signal emphasis processing like HPF is performed with respect to a luminance signal and a processing like LPF with replenishment of the low-midrange frequency signal is performed in an LPF step and a color signal step with respect to color difference signals. Then, the luminance signal and color difference signals are outputted by prescribed clock pulses. The clock pulse of the color difference signals may be set lower than the clock pulse of the luminance signal according to the condition of the image. Processed as above, a new component image signal (a luminance signal Y and any combination of color difference signals U and V, V and W, W and U) is generated from a conventional component image signal (Y and U, V, W) without loss in image information or image quality. Furthermore, the amount of data of the signal to be generated per unit of time is reduced as compared with the conventional component coding system of 4:1:1 or 4:2:0 (MPEG). Thus, a signal processing method and device which enables signal transmission with lower transmission rate can be achieved.
摘要翻译：当在信号处理步骤中输入输入分量图像信号时，相对于亮度信号执行像HPF这样的高频信号强调处理，并且在LPF中进行处理，在LPF中执行补充低中频信号步进和色差信号步进。然后，通过规定的时钟脉冲输出亮度信号和色差信号。可以根据图像的条件将色差信号的时钟脉冲设置为低于亮度信号的时钟脉冲。如上所述，从传统的分量图像信号（Y和U，V，W）产生新的分量图像信号（亮度信号Y和色差信号U和V，V和W，W和U的任何组合）不损失图像信息或图像质量。此外，与传统的4：1：1或4：2：0（MPEG）组件编码系统相比，每单位时间产生的信号的数据量会减少。因此，可以实现能够实现具有较低传输速率的信号传输的信号处理方法和装置。

摘要： A dichroic mirror for reflecting red light for optical separating and a dichroic mirror for reflecting red light for optical synthesizing are installed on the same plane in an image generating apparatus of the present invention. In addition, a dichroic mirror for reflecting blue light for optical separating and a dichroic mirror for reflecting blue light for optical synthesizing are installed on the same plane. Accordingly, a compact configuration can be realized. Since a main reflecting mirror is a rotating elliptic mirror and a lamp is located on a focus or around the focus, a lighting equipment which irradiates conic luminous flux can be realized.

摘要： A plurality of liquid crystal modules is vertically and horizontally arranged, each of which is supplied light by a light source via optical fibers. A screen can be wound up at a cabinet. An image from each of the plurality of liquid crystal modules does not interfere one another because a light shielding board is installed.

摘要： In a video projector, first and second light sources respectively emit first and second collimated, white light beam, a luminance optical modulation means modulates the first light beam in accordance with a luminance signal of an input video signal, a chrominance optical modulation means modulates the second light beam in accordance with a chrominance signal of the input video signal, a first projecting means projects the first light beam having been modulated by the luminance optical modulation means onto a projection screen to form a projected luminance image on the screen, and a second projecting means projects the second light beam having been modulated by the chrominance optical modulation means onto the projection screen to form a projected chrominance image on the screen. The projected luminance image and the projected chrominance image are superimposed with each other on the screen to form a full color image.
