Abstract: An apparatus for reading a radiographic image is provided with a holding section for holding a medium taken out from a cassette, wherein the medium has a recording surface on which the radiographic image is stored, the hold section holding the medium such that the orientation of the recording surface is substantially vertical; and a reading section for reading the radiographic image on the recording surface of the medium held by the holding section, thereby obtaining radiographic image information from the recording surface.

Abstract: Image information recorded on a sheet-shaped recording medium is read and converted into digital image data, wherein the image information includes medical image information and image information used for orientation discrimination and the image information for orientation discrimination is recorded at a predetermined position on the sheet-shaped recording medium. The position of the image information for orientation discrimination on the sheet-shaped arrangement of digital image data corresponding to the sheet-shaped recording medium is recognized. Then, the mounted orientation of the sheet-shaped recording medium is discriminated on the basis of the recognized position of the image information for orientation discrimination on the sheet-shaped data arrangement of digital image data.

Abstract: An image reading apparatus which includes a primary scanner for scanning an original X-ray image obtained using a grid and recorded on a recording medium with light in a primary scanning direction. A clock signal generator generates clock signals having a frequency N times as high as a frequency of pixel clock signals, wherein the pixel clock signals correspond to a desired pixel size, and wherein N is a positive integer. A converter converts a light beam from the recording medium into electric signals by a scanning operation of the primary scanner, and converts the electric signals into digital signals based on the clock signals. A low pass filter is provided which has at least one set of filter characteristics having a cut-off frequency between 1/3 and 2/3 of the frequency of the pixel clock signals for filtering the digital signals converted by the converter.

Abstract: An image reading apparatus that illuminates or irradiates a document by scanning for reading in two orthogonal directions. In a mode preceding a reading mode, it photoelectrically converts transmitted or reflected light into an image signal, employs a stored threshold value for comparison with the image signal, and discriminates document position or size based on the comparison to set a reading area for the document, such as a medical X-ray film. A reading control inhibits the reading mode while the document is irradiated in the sub-scanning direction from its tip edge across a predetermined distance. The discrimination of a possibly faulty position, including some inclination error, of the X-ray film and the setting of the reading area compensates for the faulty position before the subsequent reading mode begins. The setting of the reading area can involve some re-conveying of the document. An alarm is generated if the discrimination determines that an appropriate reading area cannot be set.

Abstract: An image data compression apparatus, in that a component characteristic value of an AC component in a block obtained by dividing digital tonal image data is compared with a predetermined threshold value so that a frequency of an AC component at the highest frequency side having the component characteristic value over the threshold value is determined as a boundary value, and in that the AC component exceeding the boundary value is not handled as a substantial transform coefficient. When the transform coefficients in a high-frequency side in the block is cut according to an image content of the block a lower limit of a frequency to be cut is determined, so that a frequency lower than the lower limit determined may not be cut.
