Abstract: PROBLEM TO BE SOLVED: To provide technologies to efficiently transmit information if an image output apparatus, such as a digital camera, and a printing apparatus directly communicate, and allow the printing apparatus to quickly determine whether or not the connected image output apparatus can migrate to a specified protocol to print.
SOLUTION: If a digital still camera DSC and a printer are direct-connected and images stored in the DSC are directly printed, the printing apparatus sequentially requires information stored in the digital still camera to determine whether or not the digital still camera is compatible with a photo direct printing mode (S26 to S31). As a result, if the printing apparatus receives scripts including specified information (S30;Yes), it determines that the connected digital still camera is compatible with the photo direct printing mode. Thereby, the digital still camera assigns the first number that the printer requires to a script file that is authentication information, so that the number of repetitions from S26 to S31 is reduced.

Abstract: PURPOSE:To always give the optimum color correction to at least one of using colors and at the same time to prevent the generation of a pseudo contour, by changing the combinations of using coloring materials in response to the input picture data to perform correction of different colors. CONSTITUTION:The video signal containing each of R, G and B signals and a cycle signal is led to an A/D converter 2 via an interface 1, and gradation signals of R, G and B are converted into digital signals. These digital signals are applied to a picture processing circuit 4 via a line memory 3 to be converted into signals of C (cyan), M (magenta), Y (yellow) and BL (black), respectively. Furthermore these signals are converted into applied voltage value of each head and supplied to a head driver 6. Here the color correction is carried out on the basis of the input data and by switching successively plural types of color correction functions. Then the amount of ink sprayed from an ink jet head 9 is controlled.

Abstract: PURPOSE:To improve the reproducibility in the high light part detected from input image data by providing means for controlling a printer so as to form the dots of the coloring material selected according to the input image data. CONSTITUTION:The input image data of red R, green G and blue B for every picture element of an original picture is converted to the densities of yellow Y, magenta M and cyan C by a YMC converter 21 and said densities are subjected to a gamma conversion by a gamma converter 22 and a color correction by a color corrector 23. The max. values of Y, M and C are detected from the input image data in a comparator 24 and one among limiters 25-27 is turned on in accordance with the color detected simultaneously. The limiter compares the data and the respective min. optical reflected density values of Y, M, C when designated as YL, ML, CL, and when the data is smaller, the limiter outputs respectively the values of YL, ML, CL. Yellow, magenta and cyan inks are discharged from heads 31-33 according to the impressed voltage. The min. dots are thus striken in the high light part as well and therefore the good picture elements are obtd. without unnatural white blank-out or the decrease in the contrast over the entire part.

CONSTITUTION: In the example, 640 samplings are executed in the horizontal scanning direction and 480 samplings are executed in the vertical scanning direction when the image is formed, and when the histogram is obtained, 64 samplings are executed at an interval of 10 samplings in the horizontal scanning direction. From the above, after dark and highlight points are set, the actual image-forming is executed. Normalized (RGB→CMY is also converted.) C-M-Y data are sent to a masking circuit 7 to remove the non-uniform color component of ink to be printed next, and printed at an ink jet printer main body 9. When the test print mode is on, the histogram is obtained. The element, which changes a dark point only, is divided and printed.

Abstract: PURPOSE: To express a density variation without losing a quality sense, by switching a light and shade dot at a point where a density level is changed suddenly.
CONSTITUTION: Inks whose coloring density are different are used for expressing the light and shade of an image. Also, the tone is expressed by controlling the size of a dot. Which coloring density ink is used is determined by an input picture signal, and in case of ink jet, how many volts are applied to the head is determined. Also, differentiation to a density signal of the input picture signal is executed, and as a result of the differentiation, when a part where density is varied suddenly is detected, the kind of ink to be used is changed by making its point a boundary. As for a dot having ink of a dark color and a small diameter, and a dot having ink of a light color and a large diameter, even if each tone is same, each quality sense is different due to a difference of the dot diameter. A difference of the quality sense, however, is not felt by changing ink at a sudden variation point of density.
