摘要： A number-of-pixels conversion apparatus for converting the number of pixels of an original image or a display apparatus using the same has an interpolation coefficient generator for generating an interpolation coefficient that is obtained by a function with the distance between an interpolation pixel and a reference pixel, said function has a first derivative that is smaller than −1 at least in a partial range, whereby the apparatus enables a pixel data interpolation process that produces a post-conversion image that is low in the degree of blurring even if the original image has a steep density variation.

摘要： A field-sequential color image display device receives red, green, and blue image data, and decomposes the received data into more than three monochromatic images. The monochromatic images may include at least two red, two green, and two blue images. Alternatively, the monochromatic images may include one white image and at least one red, one green, and one blue image. The monochromatic images are displayed sequentially, each monochromatic image followed by another monochromatic image of a different color. The increased number of monochromatic images alleviates the problem of color breakup.

摘要： A display device scans a phosphor screen with three independently modulated ultraviolet beams. The screen is coated with three types of light-emitting phosphor dots, each emitting a different color of visible light when illuminated by ultraviolet light. A color separator such as an aperture mask or lens array directs each ultraviolet beam onto phosphor dots of one of these three types. Two or more of these display devices can be combined to obtain a larger screen size.

摘要： There is provided a scanning line interpolation device which is capable of providing an interpolated image with increased reproducibility of vertical high-frequency components in a still picture part. Preceding-field image data is stored in a field memory, and thereafter reference pixels which are located in an interpolation pixel position and its surrounding positions and required for interpolation are extracted from the preceding-field image data stored in the field memory and current-field image data. An inter-field motion judgement portion detects whether or not there is a motion of an image between preceding and current fields based on the extracted reference pixels. If the inter-field motion judgement portion detects that there is a motion, a selection circuit selects in-field interpolation data calculated in an in-field interpolation value calculation circuit from the current-field image data among the reference pixels. If the inter-field judgement portion detects that there is no motion, the selection circuit selects the preceding-field image data located in the interpolation pixel position among the reference pixels. Then, the selection circuit outputs the selected data as interpolation pixel image data.

摘要： In the image processors and the image processing methods of the present invention, the number of bits for quantizing image data is adjusted on the basis of a dynamic range of each block. Therefore, the error introduced by encoding is reduced without increasing the data amount of the encoded image data, and the response speed of a liquid crystal can be controlled appropriately by preventing unnecessary voltages from being applied due to the error introduced by encoding.

摘要： A light diffusion element includes a light diffusion layer that contains at least two types of liquid crystal molecules each having a different light scattering characteristic defined by a voltage and a refractive index. A pair of electrodes sandwiches the light diffusion layer, an applying unit generates and applies a variable voltage to the pair of electrodes, and a voltage changing unit varies the voltage generated by the applying unit. The voltage changing unit varies the voltage such that each of the refractive indexes of the liquid crystal molecules in the light diffusion layer changes temporally.
