    摘要: An image can be outputted with a high sharpness without deteriorating a resolution. In order to output an image of a high picture quality while suppressing the occurrence of a moire, an exposure amount is modulated in accordance with pixel density information of the image divided into pixels of a predetermined size by an exposure amount modulating unit in a light scanning unit, thereby expressing an image dark/light state. In this case, in a highlight density region in which a pixel density is equal to or less than 1/3 of the maximum image density, the density data of two adjoining pixels is modulated by one pixel and the other pixel is not recorded. In a density region in which the image density lies within a range from 1/3 to 1/2 of the maximum image density, a part of the density data of one of the two adjoining pixels is transposed to the other pixel. In a density region in which the image density is equal to or larger than 1/2 of the maximum density, the pixel transposition is not performed.

    摘要: A plurality of elongated beams are generated by dividing a laser beam, said plurality of beams being respectively applied to corresponding lens elements of a flyeye lens array. The structure is arranged in such a manner that the diameter of the plurality of the beams in the shorter direction is made smaller than that of each of the lens elements, so that the plurality of beams are further divided into a plurality of elongated secondary beams by the flyeye lens. The plurality of the secondary beams are bundled on a diaphragm in such a manner that their lengthwise directions substantially coincide with each other so that a beam pattern is formed. A row of openings arranged in the lengthwise direction of the beam pattern and formed in the diaphragm member are uniformly and efficiently irradiated with the thus-formed beam pattern. Then, the image of the row of openings is projected onto a plastic plate or the like so that a multiplicity of holes are formed in the plate. As a result, a nozzle plate of an ink jet printer head can be accurately and quickly manufactured.

    摘要: A projection type image display apparatus which suppresses deterioration in luminous efficiency of an organic EL element and reduces flickering of projected images and an amplitude of a power supply capacity is disclosed. The apparatus comprises an electroluminescence (EL) element, a projection optical system, and a controller which generates drive signals to control the emission amount from the EL element. An EL material used for a luminescent layer of the EL element is a phosphorescent material which emits phosphorescence by priority, which is emitted from an excited triplet state. The controller generates drive signals by superimposing an intermittent turning-on signal on emission amount modulating signals to modulate current values to be injected into pixels according to display image signals.
