摘要： A signal processing circuit is disclosed in which the DC level of a signal having constant signal value periods during each of non-inverting periods and inverting periods can be correctly adjusted. The circuit has first and second sample-and-hold sections which perform sample-and-hold operations on the signal value which occurs during the constant signal value periods of the non-inverting and inverting periods. An averaging section averages the sample-and-hold values of the sample-and-hold sections. A feedback section compares the output value of the averaging section with a reference value and, upon comparison, feeds back the resulting value to the signal processing section. Also disclosed is a liquid crystal display apparatus using the above-described signal processing circuit.

摘要： An image pickup system includes an image pickup element with an image pickup region in which a plurality of pixels are arranged in a matrix, and a controller configured to control reading of signals from the pixels. The controller divides a first frame period in which a first image is read from the image pickup element into a plurality of divided frame periods, including first and second divided frame periods. When the number of pixels included in the first image is larger than the number of pixels included in a second image, a second frame period required for reading all signals from the pixels included in the second image is inserted between the first and second divided frame periods. A refresh cycle of the second image is shorter than a refresh cycle of the first image.

摘要： Image qualities of a full color image can be changed as needed by arranging two flat round color filter plates so as to overlap each other in part and so as to be selectively rotationally driven. Further, these color filter plates and are set so that the color characteristics thereof are mutually different from each other. White light from a lamp is injected into an overlapping portion A of these color filter plates, but this white light is converted into light of each single color as the color filter plate is rotationally driven, and this light irradiates an image display element. At the image display element, an image is switched or changed in synchronization with the irradiation of the light in single colors; therefore, the image is recognized as a color image and the colors of a plurality of color images are mixed to be seen and recognized as full color image. The image qualities of this image are switched or changed by means of changing the driven color filter plates.

摘要： A display and its driving method is provided in which the image signal can be input into a panel having a smaller number of rows than the number of scan lines for the image signal, without producing image distortion. For example, a signal of the PAL system having more rows is displayed on a display for the NTSC having less rows. The signal control is made such that an image signal is written in two rows at every horizontal scan, except for a particular image signal, but the particular image signal is written in one row. Normally, the image signal for every horizontal scan is written in two rows, but only a particular image signal for every horizontal scan is compressed and displayed in one row. Accordingly, the vertical resolution is not degraded, unlike the scan for thinning out the image signal.

In a first frame, signals are output from pixels in every (n+1)th row of the pixel array, and in a second frame following the first frame, signals are output from pixels that are different from the pixels from which the signals are output in the first frame and that are located in a first set of rows defined by selecting every (k+1)th row of the pixel array.
