摘要： The present invention allows the detection of ink in a printing head that can be widely applied to various printing systems by significantly simplifying its configuration. There are a heater for supplying an energy to eject ink, a driver for driving the heater, and a detection electrode capable of detecting a voltage variation that arises between the heater and the driver and that depends on the driving of the heater. Furthermore, an insulating film that covers the surface of the detection electrode protects the detection electrode from chemical or physical change. Furthermore, a reference element group or a reference unit that produces a signal as a reference of the detection signal avoids the influence of noise. Furthermore, an energy-generating element and another signal source improve the accuracy of ink detection. A drive pulse which is insufficient to eject ink may be supplied to the heater to improve the accuracy of ink detection.

摘要： An image processing apparatus includes an obtaining unit, a determination unit, a setting unit, and a processing unit to perform an image edge intensifying processing. The obtaining unit obtains image data by reading a document. The determination unit determines an image edge direction. The setting unit sets an edge intensifying processing intensity based on the image data and a processing intensity determined corresponding to a difference between resolution in a main scanning direction and resolution in a sub-scanning direction. The processing unit performs the image edge intensifying processing according to the set intensity. In response to the resolution of the image data being higher in the sub-scanning direction than in the main scanning direction, the setting unit sets a higher intensity of the edge intensifying processing in response to the edge direction being along the sub-scanning direction than in response to the edge direction being along the main scanning direction.

摘要： In an ink-jet printer, when a gray is expressed by mixing ink of a plurality of colors, there is a concentration in which a use amount of the ink is large. If the gray in an edge portion of a character has the concentration of the large ink use amount, a bleeding of the ink occurs and a thin portion of the character is sometimes damaged. If the gray in the character edge portion has the concentration of the large ink use amount, the gray in the character edge portion is changed to the white side by image correction, and the damage of the character thin portion caused due to the ink bleeding is prevented.

摘要： There is disclosed an image processing apparatus which applies an adjusting process to an image that includes a pixel to be processed. The image processing apparatus extracts an image area with a predetermined size including the pixel to be processed. The apparatus calculates a variation associated with the pixel to be processed from signal values of pixels included in the image area. The apparatus calculates a variation time count in the image area from the signal values of the pixels included in the image area. The apparatus calculates adjusting levels Fz1, Fz2, and Fe from the variation time count and the variation using a definition unit which defines correspondence among the variation time count, the variation, and the adjusting levels, and applies an adjusting process to a signal value of the pixel to be processed by the calculated adjusting levels. Note that the definition unit defines the correspondence so that the adjusting levels Fz1, Fz2, and Fe progressively change in accordance with different variation time counts or different variations.

摘要： An inkjet printing apparatus is adapted to use a non-contact method for detecting the presence and the amount of liquid, in the form of ink droplets discharged from a printhead or ink tank, using electromagnetic waves in the form of infrared rays. The apparatus and method employ an infrared sensor to detect infrared radiation emitted by the ink in proportion to the amount of ink present. The apparatus and method further employ one of various shielding members to prevent the intrusion of infrared radiation noise into the infrared sensor field of detection, and, in some aspects, a fan to control air flow within the field of detection. The result is less noise in the detection signals of the infrared sensor, and therefore a more sensitive and more reliable liquid detection method and liquid detection apparatus.

摘要： There is disclosed an image processing apparatus which determines an attribute of an image including a pixel to be processed. An image area having a predetermined size including the pixel to be processed is extracted (S701). A variation related to the image area is calculated based on pixel values included in the image area (S705). Pixels in the image area are converted into N-ary data (ternary data or higher) in accordance with the calculated variation (S709). The attribute of the pixel to be processed is determined by analyzing the N-ary data as a result of the N-ary conversion (S711).
