Patent Issued for Image Processing Apparatus, Computer-Readable Recording Medium, and Image Processing Method to Form an Image of Improved Quality (USPTO 9396417)

By a News Reporter-Staff News Editor at Computer Weekly News -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventors Sohgawa, Norimasa (Kanagawa, JP); Hatanaka, Shinichi (Tokyo, JP), filed on February 9, 2015, was published online on July 19, 2016.

The patent's assignee for patent number 9396417 is RICOH COMPANY, LTD. (Tokyo, JP).

News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates to an image processing apparatus, a computer-readable recording medium having an image processing program, and an image processing method.

"Known recording apparatuses by an inkjet method form images by ejecting ink or other droplets from nozzles. Techniques have also been developed that reduce uneven color or streaks that arise from dots overlapping unique to the inkjet method. One disclosed example of such techniques prevents streaks and unevenness by forming, over a layer of dots ejected earlier, dots with a smaller ejection amount than in the dots ejected earlier.

"To form a laminated image formed by superimposing one dot on top of another, the greater the number of layers, the more frequently surface irregularities of the laminated image occur due to, for example, accumulation of uneven ejection by nozzles that eject droplets, resulting in degraded image quality.

"In view of the foregoing problem, there is a need to provide an image processing apparatus, a computer-readable recording medium having an image processing program, and an image processing method capable of generating print data that can form a laminated image with minimized degradation of image quality."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "It is an object of the present invention to at least partially solve the problems in the conventional technology.

"According to the present invention, there is provided an image processing apparatus that outputs print data to a recording apparatus including a recording unit that causes each of a plurality of nozzles to eject droplets to record dots on a recording medium, the image processing apparatus comprising: an acquiring module that acquires image data for an image to be formed by the recording unit; a determining module that determines whether or not the image data is laminated image data formed of a plurality of layers; and a generating module that generates, when the image data is the laminated image data, the print data that assigns nozzles for recording dots corresponding to respective pixels of the laminated image data such that a specific nozzle for recording dots that correspond to pixels at an identical pixel position in the laminated image data varies from one layer to another.

"The present invention also provides a non-transitory computer-readable recording medium that contains an image processing program that causes a computer to execute: acquiring image data for an image to be formed by a recording unit that causes each of a plurality of nozzles to eject droplets to record dots on a recording medium; determining whether or not the image data is laminated image data formed of a plurality of layers; and generating, when the image data is the laminated image data, print data that assigns nozzles for recording dots corresponding to respective pixels of the laminated image data such that a specific nozzle for recording dots that correspond to pixels at an identical pixel position in the laminated image data varies from one layer to another.

"The present invention also provides an image processing method comprising: acquiring image data for an image to be formed by a recording unit that causes each of a plurality of nozzles to eject droplets to record dots on a recording medium; determining whether or not the image data is laminated image data formed of a plurality of layers; and generating, when the image data is the laminated image data, print data that assigns nozzles for recording dots corresponding to respective pixels of the laminated image data such that a specific nozzle for recording dots that correspond to pixels at an identical pixel position in the laminated image data varies from one layer to another.

"The above and other objects, features, advantages and technical and industrial significance of this invention will be better understood by reading the following detailed description of presently preferred embodiments of the invention, when considered in connection with the accompanying drawings."
