A printing device comprising a printing head including a plurality of nozzles configured to discharge ink to a printing medium are arranged, and a control unit configured to control discharge of the ink. The printing head is configured to discharge the ink along with scanning that is a relative movement in a predetermined direction with respect to the printing medium, and in test printing for printing a TP on the printing medium, the control unit performs control such that the ink of a first discharge amount is discharged from the nozzles when a color difference between the TP and the printing medium is greater than a predetermined threshold value, and the ink of a second discharge amount that is greater than the first discharge amount is discharged when the color difference between the TP and the printing medium is equal to or smaller than the threshold value.

Printing device and printing method

A printing unit that prints an inspection image, a reading unit that reads the inspection image printed by the printing unit, and an analysis unit that performs analyzation based on a reading result read by the reading unit are provided. The inspection image includes an inspection pattern of a plurality of colors, the inspection pattern including a first position detection mark printed in a first color, a second position detection mark printed in the first color, and a second color inspection pattern printed in a second color different from the first color, the printing unit prints the second color inspection pattern at a position adjacent to the first position detection mark, and the analysis unit specifies a first position of the first position detection mark in a first region, and specifies a second position of the second position detection mark in a second region smaller than the first region.

Liquid ejection apparatus, image processing method, and image processing program

A printing apparatus includes a head configured to discharge liquid to a printing medium, a carriage configured to move the head back and forth to one side and another side in a scanning direction with respect to the printing medium, and a control unit configured to perform printing of a printing image with the liquid by controlling driving of the head and the carriage. When performing printing of an end portion of the printing image on the one side, the control unit performs the printing by a first scan in which the head is moved from the one side to the other side, and when performing printing of an end portion of the printing image on the other side, the control unit performs the printing by a second scan in which the head is moved from the other side to the one side.

Printing apparatus and printing method

A recording control device that controls a recording device that discharges a dot to perform recording includes an edge detection unit configured to detect an edge of an image represented by image data, and a recording control unit configured to generate dot data specifying the dot based on the image data and to cause the recording device to perform recording based on the dot data. The recording control unit causes an internal region, located on an inner side of an edge region including the edge of the image, to be recorded using a dot having a smaller size than that of a dot used for recording of the edge region, or to be dot-off.

Recording control device, recording device, and recording control method

An image processing device includes a code detection unit configured to detect a code image included in the input image, a pixel value determination unit configured to determine whether a pixel value of each pixel included in the code image corresponds to an intermediate color between a color of code elements constituting the code image and a color of a space between the code elements, and a pixel value converting unit configured to convert a pixel value of a separated pixel that is separated from the code elements by k pixels or more, among intermediate color pixels that are pixels determined to correspond to the intermediate color, into a pixel value brighter than the intermediate color, wherein k is an integer of 2 or greater.

Image processing device, image processing method, and recording device

An image processing device configured to generate printing image data used during printing from input image data including a bar code constituted by a bar element and a space element that are a plurality of elements arranged based on a predetermined standard, includes a frequency distribution calculation unit configured to acquire widths of the plurality of elements respectively to calculate a frequency distribution of the widths of the plurality of elements, a standard width determination unit configured to determine a standard width of the plurality of elements of the barcode in the printing image data using the frequency distribution, and a correction unit configured to correct the widths of the plurality of elements of the barcode in the printing image data to the standard width.

Image processing device, printing apparatus, and image processing method

A printing apparatus including a code information detecting unit configured to detect code information in image data, and a printing controller configured to control bidirectional printing to repeat a first scan including ink ejection in accordance with movement of a printing head to a first side in a main scanning direction, a second scan including ink ejection in accordance with movement of the printing head to a second side in the main scanning direction, and medium transport performed between the first scan and the second scan. The printing controller is configured to perform printing by any one of the first scan or the second scan in an area of the code information detected by the code information detecting unit, during the bidirectional printing based on the image data.

Printing apparatus and printing control apparatus

An image processing apparatus includes a face direction estimating section that estimates a direction and a degree of swing of a face in a target image including a face image when a front direction of the face is used as a reference, and an image correcting section that transforms a correction target area to be corrected, which includes at least a part of the face image, in accordance with the degree of swing.

Image processing apparatus, image processing method, and computer program for processing images

There is provided an image processing apparatus that specifies a position of a predetermined characteristic portion of a target face image.
