Abstract: In a case where a user places a document placed on a document positioning glass plate without sufficiently opening an automatic document feeding device, sheet size information will not be reset and an image may be read based on incorrect size information. Therefore, in the present invention, an angle at which the size information is reset is set to an angle between a first angle at which the automatic document feeding device is closed, and a second angle (?1) at which the automatic document feeding device is moved to open automatically after being released from a holding state by a holding unit.

The print control apparatus includes a print data generation unit that generates, according to the image, the print data defining on/off setting of dots in each of pixels with respect to the ink of each of the plurality of colors. The print data generation unit generates the print data for the ink of a specific color having highest brightness among the plurality of colors through first gray scale conversion using a dither mask, and generates the print data for the ink of the plurality of colors except for the color subjected to the first gray scale conversion, through second gray scale conversion using a line screen.

Abstract: An image reading device includes an accommodation section, an aligning member, a reading member, and a width detector. The accommodation section accommodates at least one document. The aligning member is provided in the accommodation section, is supported in a movable manner in a width direction intersecting a transport direction of the document, and aligns a widthwise edge of the document. The reading member reads an image of the document passing through a read position preset in a transport path. The width detector detects a width of the document based on a widthwise position of the aligning member if the document is of a typical size, and detects the width of the document based on the image read by the reading member if the document is of an atypical size.

Abstract: Disclosed embodiments relate to a method implementable on a computing device for determining color characteristics of an image. The method includes identifying one or more regions in the image based on a luminance value associated with pixels in the image. Each region comprises a set of pixels having a predefined range of luminance values. The set of pixels associated with the one or more regions are categorized into one or more predefined color categories corresponding to each of the one or more regions, based on a chroma value associated with each pixel in the set of pixels. The color characteristics of the image are determined based on a count of the categorized pixels in each of the one or more predefined color categories.

Abstract: To suppress an effect caused by a thermochromism phenomenon in which the color of an image whose color is to be measured changes depending on temperature and to accurately detect the color of the image whose color is to be measured. An image forming apparatus includes a color sensor that measures the color of an image fixed onto recording paper downstream of a fixing unit in a direction in which the recording paper is carried. The image forming apparatus corrects a result of the measurement of the color obtained by the color sensor in such a way as to suppress an effect due to the temperature of the recording paper at the time of the measurement of the color on the recording paper.
