摘要： An image file for recording natural images, a generation method of the image file and an image display apparatus for displaying image data from this image file. The image file includes image data obtained by digitizing an original, and conversion tables for separating the color tones of the original into R, G and B and converting the changes of the color tones to input luminance-v-output luminance. The image display apparatus controls a color look-up table by the conversion tables read out from the image file, and displays the image data read out from the image file. The generation method of the image file includes reading development data by reading the first original by a scanner, generating a histogram between luminance and appearance frequency for each of R, G and B, integrating the appearance frequency to obtain a first cumulative histogram, generating similarly the second cumulative histogram for each of R, G and B of the final original to obtain conversion tables for the second histogram with the first cumulative histogram being the reference, and continuously displaying the color tones of a still image by using the image data and the conversion tables of the first original.

摘要： When a document and a recording medium are moved in a vertical scanning direction to read the document and record signals on the recording medium, the read signals are stored in a line buffer memory. The present invention changes over hysteretically a high speed vertical scan mode and a low speed vertical scan mode in accordance with the number of the buffered code bits in the line buffer memory to read the document and record the signal on the recording medium. Thus, the present invention reduces the number of stops of vertical scan.

摘要： A cathode ray tube having a viewing screen on which time points represented by a plurality of points spaced from one another with a predetermined time interval are displayed in the raster direction, while display quantities of trend graphs are displayed as functions of the time points in the direction perpendicular to the raster direction by a plurality of points spaced from one another with a predetermined interval. A raster scanning is effected by sweeping the viewing screen with a scanning point whereby the scanning lines thus produced are correlated to the spaced points representing the display quantities. Apparatus stores the display quantities of the trend graph corresponding to the time points, sequentially reads out the display quantities from the memory apparatus in the order of the time points, and compares the display quantities read out from the memory apparatus with a display quantity represented by an instant scan line. The comparison apparatus compares the display quantity read out corresponding to an instant time point and an instant position of the scanning spot of the instant scan line with a display quantity represented by an instant scan line, supplies a video signal to the cathode ray tube when the instant display quantity represented by the instant scan lines lies in a range delimited by the display quantity at the instant time point and the display quantity at the select one time point of the time points immediately preceding and following the instant time point.
