The image processing apparatus executes a zoom process to an image data depending on a received zoom level, selects a dither matrix from a plurality of dither matrices each having a different resolution. The image processing apparatus selects a dither matrix that has a higher resolution in a case that the received zoom level is equal or less than a first zoom level to reduce the image data. Furthermore, the image processing apparatus selects a dither matrix that has a lower resolution in a case that the received zoom level is equal or more than a second zoom level to enlarge the image data.

Apparatus and method reduce banding by addressing an image region at under 100% coverage, and adding colorant quanta to selected pixels already receiving that colorant. The amount of that colorant in some pixels is zero, in others a first nonzero number of quanta, in still others a second nonzero number—different from the first. In another aspect, the invention is a method of adding colorant in a region to which colorant is already addressed; it eliminates or reduces white- or light-line banding by automatically establishing a ratio, below half, of number of added-colorant pixels to total number of addressed pixels.

A durable and wear resistant synthetic sports field having a plurality of strips having a plurality of fibrillated polypropylene strands tufted within a multilayer backing material. The strands are tufted in a wide variety of pile heights, patterns, gauges, and stitch patterns depending upon end use. A particulate matter infill is introduced onto the strips at a depth between about 10% and 50% of the overall height of the strands.

A mechanically deformed nonwoven comprising a plurality of protrusions extending outwardly from a first surface of the nonwoven and having openings c corresponding to the protrusions in a second surface of the nonwoven. The nonwoven has a Horizontal Bending Drop at 100 mm of at least 75 mm and a Z-Compliance Index of at least 50 mm3 / N. The nonwoven can be used in absorbent articles such as diapers as an acquisition layer between the absorbent core and the backsheet and / or as a masking layer between an absorbent layer core and the backsheet.

An ultrasonic atomizing core and an ultrasonic atomizer, an ultrasonic atomizing sheet is vertically installed on the atomizing seat, an atomizing chamber is arranged on the atomizing surface side of the ultrasonic atomizing sheet, and an air inlet and an air outlet are arranged on the atomizing chamber , the atomization surface of the ultrasonic atomization sheet is in contact with the middle of the oil-conducting cotton to form an atomization area, the air inlet is set perpendicular to the ultrasonic atomization sheet and located below the atomization area of ​​the ultrasonic atomization sheet, and the air outlet is parallel to the ultrasonic atomization The sheet is set and located above the atomization area. When the airflow passes through the atomization chamber, the flow path of the smoke in the atomization chamber is peak-shaped, so that the atomization chamber is divided into an inert area, a flow area, and a rapid area according to the flow rate of the smoke. An oil storage tank is arranged on the atomization seat, and an oil guide cotton is arranged between the oil storage tank and the atomization chamber. Cotton pressure spring in the atomization area, and the two ends of the oil-conducting cotton extend into the oil storage tank through the oil-conducting cotton through the groove.

A printing apparatus and a printing method are provided. The printing apparatus that performs a printing through an inkjet method includes: a conveyor driver which is a medium conveyor device; a plurality of ink ejection portions arranged side by side along a conveyance direction; and a plurality of ultraviolet light sources which are a plurality of fixing devices. Each of the ink ejection portions includes a plurality of inkjet heads arranged side by side along the conveyance direction. Each of the plurality of ultraviolet light sources is disposed on a downstream side in the conveyance direction with respect to any one of the ink ejection portions. After the medium passes a position facing the plurality of inkjet heads in one of the ink ejection portions, the ink ejected by the one of the ink ejection portions is fixed to the medium.

A method for reducing an amount of marking material for printing a binary image on a receiving material uses a printing process configured to apply print pixels and to associate each image pixel with at least two print pixels. A print signal is generated indicating for each print pixel whether marking material is to be applied. The print signal is filtered by a predefined mask that defines for which print pixels no marking material will be applied independent of the pixel value of the associated image pixel. The print pixels that are blocked by the mask define a regular pattern to avoid graininess in the printed image. The main effect on print quality is a reduction of the contrast in the image. By choosing one of a set of at least two masks, the user selects the amount of reduction that is realized in the print process.

The invention provides a preparation method of Chinese yam and pleurotus eryngii egg rolls. The preparation method comprises the following steps: cleaning Chinese yam and slicing the Chinese yam with peels, implementing low-temperature drying and superfine grinding; cleaning, slicing and blanching pleurotus eryngii, implementing vacuum microwave drying and superfine grinding; mixing and beating galactooligosaccharide, sucrose, palm oil, perilla oil and eggs through a stirrer until bubbling; adding the Chinese yam superfine powder, the pleurotus eryngii superfine powder, low-gluten flour, lotus powder, konjac flour and the like, mixing and beating to obtain slurry; and rolling the slurry into egg rolls through an egg roll forming machine, baking, cooling to room temperature and packaging to obtain finished egg rolls. According to the preparation method disclosed by the invention, the Chinese yam superfine powder and the pleurotus eryngii superfine powder, and particularly the Chinese yam superfine powder with peels are added in the raw materials, thus enriching nutrition of the egg rolls, improving taste, avoiding granular sensation and enhancing crispness; the perilla oil is added so that sucrose and grease dosages of the egg rolls are reduced and a special aroma of perilla is reserved; calcium absorption is enhanced due to calcium lactate and crispness is improved; and the egg rolls can condition intestines and stomach, improve digestion and absorption, and regulate blood pressure and blood lipid, and are applicable to various people.

Embodiments of the present application provide a display method and a display device for a display panel, which are used to solve the technical problem of poor display effect of an RGBW display panel in the prior art. The method includes: determining the R sub-pixel brightness value, the G sub-pixel brightness value, the B sub-pixel brightness value and the W sub-pixel brightness value of each pixel in the image to be displayed; modifying the W sub-pixel brightness value of the first type of pixels, so that all The modified W sub-pixel luminance value of the first type of pixel is smaller than the W sub-pixel luminance value before modification, and the final brightness value of the first type of pixel is obtained, wherein the first type of pixel is the text in the picture to be displayed Pixels in the display area: using the driving voltage corresponding to the final brightness value of the first type of pixels to drive the pixel units corresponding to the first type of pixels in the display screen to light up.

The invention relates to a preparation method of Pigment Red 146 emulsion. The preparation process steps are as follows: take 15-18 parts of Pigment Red 146 powder, grind it to 1000 mesh with a grinder; put the ground Pigment Red 146 powder into a reactor, Add 12 to 16 parts of emulsified silicone oil and stir at the same time; add 21 to 23 parts of emulsifier OP-9 and stir at the same time; add 11 to 14 parts of ethylene glycol and stir at the same time; add 80 to 85 parts of water, Stir evenly; finally use a homogenizer for homogenization, the homogenization pressure is 17MPa, and the homogenization time is 25min.
