摘要： In a first printing process in Steps S1 through S6, ink supply is controlled so that a measured printed density (Vn) is approximately equal to a first target density (V1). This provides a uniform amount of ink remaining on ink rollers after the first printing process. Thereafter, in a second printing process in Steps S7 through S11, printing is performed using a second target density (V2) lower than the first target density (V1). This provides a slightly reduced, uniform amount of ink remaining on the ink rollers. Thus, a novel method of presetting ink is provided which facilitates the formation of a distribution of the new amount of ink at the beginning of the next printing operation and which stabilizes the early start of printing.

摘要： After an ink feeding rate or a dampening water feeding rate is varied, a variation in the ink feeding rate or dampening water feeding rate is prohibited for a waiting period. The waiting period for prohibiting a variation in the ink feeding rate is determined by a pattern area rate of a corresponding region. The waiting period for prohibiting a variation in the dampening water feeding rate is determined by an average pattern area rate of all regions or a minimum pattern area rate among pattern area rates of all regions. When one of the ink feeding rate and dampening water feeding rate is varied, a variation in the other feeding rate is prohibited for a set period of time.

摘要： A printing apparatus has a manual control mode. The manual control mode has a proportion indication, a proportion adjustment key, a selected range adjustment key, and region selection keys. In the manual control mode, an operator selectively touches the region selection keys to select a region in which an ink key opening is to be changed. Next, the operator touches the selected range adjustment key to change the ink key opening of the selected region. The ink key opening is increased or decreased by the percentage indicated at the proportion indication the number of times the selected range adjustment key is touched. The settings made in the manual control mode are stored in a storage section, and are used to control the amount of ink supply during automatic control. Thus, the printing apparatus having the function of automatically controlling the printed density can make partial tone changes.

摘要： A positive image which resembles an object is obtained from a negative image which has various color distributions. An image analysis part judges how far image data of a negative image are from a gray line, and finds an intensity value of one optional color which provides a point on the gray line when combined with each of other colors, to thereby identify an HP (highlight point) and an SP (shadow point) on the negative image. At this stage, a pixel at which the sum of RGB-values on the negative image is approximately the largest is defined as a first HP candidate. Maximum values in the negative image are calculated for planes of the respective colors, and one set of the RGB-values is defined as a second HP candidate. Whether the first HP candidate is close to the gray line is judged. If the first HP candidate is close to the gray line, the first HP candidate is directly used as an HP. If the first HP candidate is far from the gray line, whether the second HP candidate is close to the gray line is judged. If the second HP candidate is close to the gray line, the second HP candidate is directly used as an HP. If the second HP candidate is far from the gray line, RGB-values in a white and a black regions in a gray scale are used as an HP and an SP. An image conversion part converts the negative image which is read from an image holding part into image data of a positive image which has a proper contrast, based on information regarding the HP and the SP on the negative image supplied from the image analysis part.

摘要： Detail enhancement is performed through effectively intensifying an image signal component having a predetermined spatial frequency. Based on the size of an image to be reproduced, a standard observation distance between the image and an observer is computed. A spatial frequency to be intensified is found so that it corresponds to about 12 cpd at the standard observation distance. The size of a pixel area suitable in producing an unsharp signal (U) is set to be inversely proportional to the spatial frequency. Signals (U13-U15) for various pixel areas are prepared, and one of these signals which is obtained for the suitable pixel area is selected to be the unsharp signal (U). An enhanced image signal (S+k(S-U)) is produced on the basis of the unsharp signal and a sharp signal (S).

摘要： In an image scan reader, a white reference plate is attached to a transparent plate on which an original is to be placed. Different regions are defined on the reference plate and respective optical densities on a plurality of scanning lines (L.sub.Al -L.sub.An, L.sub.Bl -L.sub.Bm) are detected and averaged within each region (R.sub.A, R.sub.B). The maximum averaged densities are selected for each given pixel position to be used for correcting the non-uniformity of CCD cells which are employed in reading the white reference plate and the image of the original.

摘要： A sharpness processing apparatus for enhancing or suppressing tone variations in an original image. A lookup table for converting RGB signals into HSL values which are the three attributes of perceived colors is used to obtain HLS values of pixels in the original image stored in a frame memory. The HSL values of the pixels are successively compared with HSL values indicating an effective range of sharpness processing determined with reference to a designated reference color, to determine pixels to be subjected to the processing. The processing is effected by applying a parameter to the RGB signals of the pixels subjected to the processing. In this way, the apparatus facilitates designation of a region of sharpness processing. Besides, the value of the parameter is variable with differences between the HSL values of the pixels corresponding to the reference color and the HSL values of the pixels determined to be subjected to the processing, whereby the sharpness processing is effected without impairing smoothness of the original image.
