A device for printing print data after converting the print data into converted print data includes a head unit for printing the converted print data by moving in a scanning direction, the head unit having at least one head line in which print elements are arranged diagonally with respect to the scanning direction, a row-order-conversion unit for rearranging rows of the print data according to an arrangement of the print elements so as to generate row-converted print data, and a column-order-conversion unit for rearranging column positions of the row-converted print data according to the arrangement of the print elements so as to generate the converted print data.

An apparatus that embeds data in an image includes a mark embedding unit that embeds a feature that forms a predetermined pattern in the image, as a mark to be used to specify an area in which the data is embedded, and a data embedding unit that embeds the data in the image of the area specified by the mark.

An embedding-availability determining unit determines an availability of embedding data into an image based on an input/output characteristic of a predetermined feature amount related to a combination of an output device that outputs an image in which the data is embedded to a medium and an input device that inputs the image that is output to the medium. A result output unit outputs a result of determination by the embedding-availability determining unit.

In an encoding device that creates an image in which data is embedded, an embedding unit divides an image into a plurality of blocks, and embeds data in the image based on a difference in value of characteristics of adjacent blocks; and a restriction information recording unit records use restriction information that restricts use of embedded data.

The present invention concerns an image processing device and an image processing method for processing a decoded image, and its objective is to optimally binarize a decoded original. After the respective density histograms of colors R, G, and B have been drawn, the hierarchical relationship between the low-density-side peak value and high-density-side peak value is investigated. A color component which is to become a binarization object is determined based on the comparison results on the number of color components whose high-density-side peak value is/are higher and the number of color components whose low-density-side peak value is/are higher, and the color of the pixel to be outputted is determined based on the comparison of the pixel with a threshold value.

A method for detecting a skew of a document image corrects the skew of a document image input from an image scanner, and achieves increased accuracy compared with prior art document image skew detection methods. After segmenting the input document image into regions each having a predetermined width, lines containing black pixels are detected from each of these regions. Then, from a region where the detected lines containing black pixels follow one another in a consecutive manner, a partial image is extracted, the skew angle of the partial image is detected, and the skew angle of the document image is determined based on the thus detected skew angle of the partial image.

An encoding unit encodes the received image data in frame units. A code buffer stores the amount of codes per 1 frame. The detection condition setting unit sets a detection condition (a standard value of a code amount difference) specified according to the detection designation data entered externally. A scene determining unit calculates the difference between the amount of codes in the present frame entered from the code buffer and the amount of codes in the previous frame. If the difference is larger than the detection condition (the standard value of the code amount difference), the scene determining unit issues a COS code indicating a scene-changed frame and sets a selection signal in an active state. A switch adds the COS code to the encoded data in the present frame and externally outputs it when the selection signal indicates an active state.
