An image processing apparatus includes: a first obtaining unit configured to obtain an original image; a second obtaining unit configured to obtain region information indicating first and second regions, the first region read in reading of a print original to have a higher density than the second region, the second region read in the reading to have a lower density than the first region; an embedding unit configured to embed information in the original image by embedding a pattern with a directivity in the first region and embed, in the second region, a pattern in which the number of pixels printed adjacent to printed pixels is smaller than that in the first region; and a control unit configured to perform control of outputting the print original by using a print image in which the patterns of the first and second regions are embedded by the embedding unit.

Image processing apparatus and image processing method that embeds information using a pattern with directivity and a pattern without directivity

An image processing apparatus includes a first obtaining unit configured to obtain an original image, a second obtaining unit configured to obtain a first multiplexed image created by embedding first information in the original image by a first method in which a shape of a pattern is changed, a third obtaining unit configured to obtain a second multiplexed image created by embedding second information in the first multiplexed image by a second method in which a density of a pattern is changed, the second information being a different type of information from the first information, and a control unit configured to perform control of outputting print data for a print original by using the second multiplexed image.

An apparatus for heating or heating and reduction raw material of a metallurgical furnace, utilizing high temperature waste gases which are released from the same furnace, has one or plural numbers of reactor(s) capable of holding the raw materials in the amount which can be charged in plural numbers of processing in the metallurgical furnace, where the reactor(s) is (are) disposed on a bypass passage connected to a pipe of a waste gas processing apparatus for cooling and scrubbing the waste gases from the metallurgical furnace. A part or all the waste gases are introduced into the reactor(s) and come into contact with the raw materials therein when the blowing in the furnace is performed to a full scale, and the reactor is cut off at the initial and final stage of blowing, whereby the heating or the heating and reduction raw material of a metallurgical furnace is effectively performed.
