Abstract: A control method for an image processing apparatus that generates a layout image in which an image is arranged in a template includes outputting a layout image in which an image represented by selected image data is arranged in a predetermined slot of slots included in a template corresponding to acquired information, wherein, in a case where first image data which represents an image that contains an object corresponding to a predetermined input and second image data which represents an image that does not contain the object corresponding to the predetermined input and an evaluation of which is higher than that of the first image data are included in a plurality of pieces of image data, the first image data is selected in preference to the second image data.

Abstract: In low-resolution processing (reduction processing) in which input image data is separated into character print data and image print data to generate print data of lower resolution than that of the input image data, if a plurality of pixels is simply reduction-processed to one pixel, color of a color image surrounding a character may change. In an image processing method, calculation for performing reduction processing so that the plurality of pixels in the input image data corresponds to one pixel in the print data is performed as follows. A ratio of using a pixel value of a character attribute pixel in the calculation is set to 0, or set smaller than a ratio of using a pixel value of an image attribute pixel. As a result, a change in the color of the color image surrounding the character can be prevented.

Abstract: Because the ejection state of a printing element in a printing apparatus may vary at all times, an inspection item for inspecting a printed image may be set in consideration of the ejection state of the printing element. An inspection item for inspecting a printed image may be set based on information including a temperature characteristic of a printing head and a state of ink such as an elapsed time from the last ejection. This allows image inspection that matches with variations in the ejection state of the printing element.

Abstract: Upon capturing a digital watermark embedded in a wide range of a print product separately plural times by moving an image capturing device, a camera shake occurs, captured images become out of focus, and the digital watermark cannot be read. In one embodiment, upon performing continuous shooting of a print product plural times, shooting is performed while changing the image capturing condition of the device, and information of the watermark is obtained based on plural captured images. Even if the device is moved to perform shooting separately plural times, it can be prevented that the distance to the print product cannot be adjusted owing to occurrence of a camera shake, and a captured image becomes out of focus. A user holds the device by the hand and can accurately perform shooting.

Abstract: Provided is a quantization processing method using dither patterns that make it possible to obtain a dot array having excellent dispersibility even in the case of a single color or mixed color inks. For this purpose, first and second dither patterns are prepared in order to respectively quantize multivalued data for a first ink to different pieces of binary data, respectively. Also, third and fourth dither patterns are prepared in order to respectively quantize multivalued data for a second ink to different pieces of binary data. Further, on the basis of a combination of the multivalued data on the first ink and the multivalued data on the second ink, a quantization unit for the first ink, and a quantization unit for the second ink are determined.

Abstract: In order to print a unit area of a print medium by a first printing scan and a second printing scan, dither patterns are formed which can control the arrangement of dots on the print medium without adverse effects of density unevenness and graininess, that are caused by printing position displacement. Regarding first and second dither patterns, information indicating whether or not a threshold is already set to a reference pixel and one or more pixels around the reference pixel in the first dither pattern is obtained for cases where each pixel in the first dither pattern is the reference pixel. A pixel in the second dither pattern to which a predetermined pixel is to be set is determined based on the obtained information. The first and second dither patterns formed in the above manner are associated with the first printing scan and the second printing scan, respectively.

Abstract: An image processing apparatus includes an image data acquisition unit to acquire image data by optically reading a document. A frequency distribution acquisition unit acquires a first frequency distribution of luminances from the image data acquired by the image data acquisition unit. A generation unit generates a second frequency distribution of luminances of a background of the document, by using a maximum frequency of the first frequency distribution as a maximum frequency of the second frequency distribution of luminances of the background of the document. An acquisition unit acquires information indicating a degree of deviation of the second frequency distribution from the first frequency distribution. A correction unit corrects the second frequency distribution based on the information indicating the degree of deviation acquired by the acquisition unit.

Abstract: A gradation-correcting curve to correct a gradation of an input image is generated. Gradation correction based on the gradation-correcting curve is made to a boundary pixel of a color-reproduction space at the same saturation as that of a target lattice point and at a hue of the target lattice point. An equal-saturation line is set by using the boundary pixel of the color-reproduction space after the gradation correction. A saturation-correction amount of the target lattice point is decided based on the gradation-correcting curve and the equal-saturation line.
