摘要:
A method for detecting defective liquid ejection includes: reading an image with a sensor, the image being formed on a medium on the basis of image data by ejecting liquid from a nozzle while relatively moving the nozzle in a direction of relative movement with respect to the medium; specifying a maximum pixel among pixels of read data continuously arrayed in rows in a direction intersecting the direction of the relative movement in the data read with the sensor, the maximum pixel having the maximum pixel value among pixels of the read data; selecting a selected pixel in the data read with the sensor, the selected pixel being included in a line constituted by a plurality of pixels including the maximum pixel arrayed in line in the direction of the relative movement; and detecting defective liquid ejection in the nozzle by comparing the selected pixel with the pixel of the image data corresponding to the selected pixel in the image data.

A discharge defect detecting device including a sensor that reads an image, which has been formed on a medium by relatively moving nozzles in a movement direction relative to the medium based on the image data and discharging a fluid, at a reading resolution lower than the resolution of image data in the relative movement direction; standard data writing unit that writes standard data having the same resolution as the reading resolution in the relative movement direction, based on the image data; and a detecting unit that compares the data read by the sensor with the standard data, to detect the discharge defects of the nozzles.
摘要:
A method for detecting a defective liquid ejection that includes a) reading, by means of a sensor, an image which is formed on a medium by nozzles ejecting a fluid onto the medium in accordance with image data while being moved relative to the medium in a relative movement direction, b) obtaining differences between pixel values of read data pixels continuously arranged in a row in a direction intersecting with the relative movement direction in data read by the sensor and pixel values of image data pixels corresponding to the read data pixels, and c) detecting a defective liquid ejection of the nozzle by comparing a maximum difference value at a point where the differences show a maximum value with a non-maximum difference value at a time when the differences do not show a maximum value.

A printing method includes obtaining scene information concerning image data from supplemental data that is appended to the image data; classifying a scene of an image represented by the image data, based on the image data; comparing the classified scene with a scene indicated by the scene information; and printing a printout that is used to urge a user to make a continuation when a mismatch between the classified scene and the scene indicated by the scene information exists.
摘要:
A liquid discharge apparatus. Each of a plurality of first nozzle rows includes a plurality of nozzles disposed in a predetermined direction that discharge cyan or magenta liquid. Each of a plurality of second nozzle rows includes a plurality of nozzles disposed in the predetermined direction that discharge yellow liquid. The number of second nozzle rows is smaller than the number of first nozzle rows. The first nozzle rows form cyan or magenta dots at pixels on a medium. The second nozzle rows form yellow dots at pixels whose number is smaller than the number of pixels at which the first dots are formed.

An identification processing that matches a preference of a user is carried out. An identifying method according to the present invention is an identifying method, in which learning is carried out using a learning sample and, based on a learning result, identification is performed as to whether or not a target of identification belongs to a certain class, including: extracting a learning sample belonging to the certain class and a learning sample not belonging to the certain class, displaying a plurality of the extracted learning samples arranged on a display section, as well as displaying a mark between the learning sample belonging to the certain class and the learning sample not belonging to the certain class, and displaying the mark between a different pair of the learning samples by moving a position of the mark in response to an instruction of a user, changing an attribute information that indicates a class to which the learning sample belongs in response to the position of the mark determined by the user, and identifying whether or not a target of identification belongs to the certain class based on a result of relearning using the learning sample of which the attribute information has been changed.
摘要:
Inspection patterns of each ink are printed on a transparent medium, by the use of a print head having a plurality of nozzle groups which discharges multiple types of ink, respectively. The inspection patterns printed on the transparent medium are read by the sensor. When reading the inspection patterns, the background color is switched, by the use of a background color switching section which faces the sensor with the inspection patterns interposed therebetween and in which a background color is switched. An occurrence of a defective nozzle is determined based on a reading result of the sensor.
