摘要:
An image processing apparatus, comprising: an input portion that inputs image data of a plurality of pages of document; a password detector that detects a password given to each of the pages; a password judger that judges from a detecting result drew by the password detector about each of the pages, whether or not a shared password issued for each page in common is detected in addition to an individual password uniquely issued for each page; an entry requester that requests entry of a shared password if it is judged by the password detector that a shared password is detected, and requests entry of an individual password about each of the pages if it is judged by the password detector that a shared password is not detected; and an output permitting portion that permits image data of all the pages each having a shared password, which is the image data inputted by the input portion, if the appropriate shared password is entered in response to the request for entry of a shared password, and permits image data of a page having an individual password, if the appropriate individual password is entered about that page in response to the request for entry of an individual password.

To read an image with high resolution via a CCD linear sensor having a limited pixel count, an image reading apparatus includes: a CCD linear sensor having arranged in a main-scanning direction photoelectric conversion elements for receiving a light reflected from an original; a piezoelectric element for providing a relative displacement between a light receiving surface of the CCD linear sensor and an object's image formed on the light receiving surface, according to a predetermined oscillation function and in the main-scanning direction; and a sensor drive circuit timing the CCD linear sensor's charge accumulation. The sensor drive circuit uses a distance from a center of an amplitude of the relative displacement to the CCD linear sensor and a time period of charge accumulation by the CCD linear sensor to determine a time point to start charge accumulation. The apparatus also includes a signal synthesizing circuit using image signals output from the CCD linear sensor during one period of the predetermined oscillation function to reconstruct an image signal of one line.

A pixel interpolating device using the IM-GPDCT method and capable of preventing noise generation divides an original image into a plurality of blocks and picks up a block to be processed as a target block. Further, an image peripheral to the target block is extracted as a peripheral image. By using the peripheral image as an extension region, DCT transform is carried out. Thereafter, the peripheral image is magnified, and the IM-GPDCT processing is carried by using the magnified image.

A mass spectrometer including a sprayer for spraying a sample solution, a needle electrode for ionizing the sample contained in the sample solution, an aperture for introducing the ions of the sample into a lower pressure region having a pressure lower than the pressure of a region in which the needle electrode is disposed, and a mass spectrometric apparatus for analyzing the ions introduced from the aperture. A direction of a spray caused by the sprayer is almost perpendicular to or at an angle with respect to a center axis of the aperture, and a tip of the needle is disposed facing to an electrode having the aperture.
摘要:
In an image reading device, a document is read while being illuminated by a fluorescent lamp and then an image signal is output. A light quantity of the fluorescent lamp illuminating the document is detected with a specified timing. Then, a fluctuation in light quantity of the fluorescent lamp is corrected based on the detected light quantity. The above timing of light quantity detection is changed according to a light quantity variation characteristic, a duration of an illuminating time of the fluorescent lamp, the number of document read operations, or a set copying mode.

Disclosed is an ion trap mass spectrometer improved to obtain a high sensitivity without the lowering of resolution. By fitting a mesh electrode to an aperture (an ion sampling aperture or an ion extracting aperture) made in endcap electrodes constituting an ion trap mass analysis region, a radio frequency electric field in the mass analysis region is not disturbed even if the diameter of the aperture is set to a large value to heighten ion transmission efficiency. By fitting a shield electrode for preventing collision of ions with an insulated ring constituting an outer wall of the mass analysis region, charging up of the insulated ring is prevented to improve stability of detection signals. Furthermore, by arranging a shield member for shielding stray charged particles detouring through the circumference of the mass analysis region to approach an ion detector, generation of noises based on these stray charged particles is prevented.

In a digital full color copying machine, image signals of red, green and blue are converted to a value signal, and histograms of the value signal for chromatic dots and achromatic dots respectively are generated. Then, a document type, such as a color standard document, a color photograph document, a color standard document having a colored background, a black-and-white standard document, or a black-and-white photograph document, is determined automatically based on the histograms. Background level of a copy is controlled automatically at an appropriate level both for a color document and for a black-and-white document having a white background according to the document type by gradation correction of the value signal. Thus, background processing is performed irrespective of a color document or a black-and-white document.
