Abstract: An apparatus continues, before a number of pages where image data started to be input reaches N pages, inputting of the image data until an amount of the image data stored in a storage unit reaches a first amount, and thereafter, continue the inputting of the image data until the amount of the stored image data reaches a second amount, which is smaller than the first amount.

Abstract: An image forming apparatus including: a user interface unit to display a user interface to select one or more low noise modes to reduce noise produced during a print standby state and a printing state of the image forming apparatus; and a controller to control the driving of a laser scanning unit and to control a print speed, according to one or more of the selected low noise modes selected through the user interface. Therefore, noise generated in the print standby state, and/or the printing state, are reduced, according to a low noise mode selected by a user.

Abstract: A lithography system and method for calculating an optimal discrete time trajectory for a movable device is described. A trajectory planner of the lithography system calculates an optimal discrete time trajectory subject to maximum velocity and maximum acceleration constraints. The trajectory planner begins by calculating a continuous time, three-segment trajectory for a reticle stage, a wafer stage or a framing blade, including a first phase for acceleration at the maximum acceleration to the maximum velocity, a second phase for travel at the maximum velocity and a third phase for deceleration at the negative maximum acceleration to a final velocity. Next, the trajectory planner converts said continuous time, three-segment trajectory to a discrete time trajectory. The time of execution of the resulting trajectory is at most three quanta greater than the time of execution of the continuous time trajectory. One advantage of the system is the reduction of scanning times of a lithography system.

Abstract: When a lamp is turned on and a wafer is placed on a light exposure surface, a controlling unit opens a shutter plate so that light is emitted on the light exposure surface and an illuminometer receives the light. An accumulated light amount measuring unit converts illumination intensity measured by the illuminometer to an accumulated light amount. The controlling unit turns off the lamp by sending a lamp OFF signal to a power supplying unit. At the same time, the controlling unit sends a shutter closing command to the power supplying unit. After the shutter is closed, the controlling unit relight the lamp by sending a lamp ON signal to the power supplying unit.

Abstract: To delete the unnecessary work, the same CCD light sensor is used for pictures of stripfilm and slid mount.

Abstract: A system for selecting decorative materials is based on large numbers of high-resolution, full color images of decorative materials stored in a compressed format on an inexpensive medium such as a CD-ROM. In creating the ROM, each image is coordinated with additional information such as style of pattern, type of material, and other auxiliary information. Before final compression and storage of the image data color information is added by spectrophotometrically analyzing the decorative material. Color values for a background color and up to four foreground colors are determined. Individual colors are then referenced to a comprehensive color standard system containing a large number of standardized color swatches. Spectrophotometric color referencing allows the data records to be rapidly searched on the basis of color, as well as the other information in the record. Wallpaper patterns, drapery material, floor covering, or paint can then be rapidly selected on the basis of matching color.

Abstract: The present invention comprises a contact printer (10) which utilizes a flat tube monitor (30) connected with a computer (40) that permits the image or light array (32) projected by the monitor (30) to be manually and selectively altered in accordance with an operator's evaluation of the image (32) directed upon a negative (20).

The invention utilizes a light position sensor (201) having a target area having a plurality of apertures (604) including at least one line segment coupled to light emitted from a plurality of positions within the light emitting area (120) of the light source (120) used for recording for detecting the position of the light intersecting the target area (201) of the sensor from the light emitting area of the light source and generating at least one signal dependent upon the light intersecting the target area.

Abstract: An original photographic image (5) is interrupted by a controlled shutter (10) and simultaneously scanned by a light collector (21) over a planar reference frame by relative movement between the image and the collector (21) along a series of linear side-by-side scanning paths. A light emitter (22) which emits light corresponding to that collected scans a similar planar frame of unexposed film (6) by relative movement between the film and the emitter along a series of linear side-by-side scanning paths. A computer (8) controls the scanning operations and the shutter (10) to cause the image reproduced on the film by exposure to the light emitter to differ to that of the original image.

Abstract: A photographic printing enlarger apparatus and method in which the enlarger head receives lights passing through a fiber optic light bundle. This light passes through a color filter system, negative, or transparency, supported by a negative carrier, and the lens. The beam of light projects the image on the surface of an exposure correction easel. A mechanical arm scans the beam of light passing through the negative in small sections, and senses the density of the negative, registering the information into a computer memory. The mechanical arm is driven to expose the light-sensitive photographic material in small sections in cooperation with a shutter system and in accordance with the information stored in computer memory. The mechanical arm is comprised of a row of several image sensors which read the wavelength of light passing through.

Abstract: The present invention relates to a method and apparatus for reducing the effect of recording errors on images and information which are recorded in sections onto a recording medium. Recording errors can detract from the quality of a recording particularly at the boundaries of recorded sections. The present invention introduces a number of methods which reduce the effect of recording errors by distributing the errors smoothly over areas of the recording, by modifying the recording level near the section boundaries, by modifying the recording process near the section boundaries, by modifying the shape, size and orientation of the recorded sections, by varying the position of the transition point from one section to an adjacent section and by introducing an overlap region which allows the section boundary to be modified.

Abstract: In the negative form of lith type film or photographic printing paper, the ground part is light-untransmissible and image part (letter, pattern) is light-transmissible. Apart from them, pinholes and stains also constitute light-transmissible areas. Although the light-transmissible areas of letter and pattern are necessary, the light-transmissible areas of pinhole and stain are unnecessary. Thus, the unnecessary light-transmissible areas must be distinguished from the necessary light-transmissible areas, and an opaque layer must be provided on the unnecessary areas to make them opaque. Generally, however, the unnecessary light-transmissible areas are minute and many in number, so that their detection and opaquing is a very laborious work. Thus, according to the opaquing method of the present invention, only the necessary light-transmissible area is detected and the other light-transmissible areas are regarded as unnecessary and the latter are stopped out.
