摘要： In an image processing device for recording images with Y, M, and C color ink, a received Bk image is recorded with a color more similar to an original black color and solves a problem caused by too much amount of ejected ink such as bleeding with other colors or feathering. An image data consisting of four color elements of YMCBk is entered from a host computer, a Bk conversion unit converts the Bk element to respective Y, M, and C elements by masking of respective Y, M, and C elements generated randomly for the entered Bk element image data, and an image synthesizing unit synthesizes the converted YMC elements with the entered YMC elements. Then, an image recording unit for forming an image with three colors of YMC forms an image based on the synthesized YMC elements and records the image on a recording medium with ejecting YMC ink from a recording head.

摘要： An ink jet recording apparatus, in which thermal energy is applied to ink in accordance with a driving signal applied to a heater to produce a bubble, by which ink is ejected onto a recording material, includes a driver for applying a plurality of driving signals to the heater for one ejection of one ink droplet. The driving signals comprise a first driving signal not ejecting the ink and a second driving signal for ejecting the ink, the second driving signal being applied after a rest period after the first driving signal. The apparatus further includes a controller for changing an amount of ink ejected by changing a length of the rest period and changing the first driving signal. The controller effects its changing operation in a first changing region in which the rest period is changed without changing the first driving signal and in a second changing region in which a length of the first drive signal is changed.

摘要： Whether or not a color image is present adjacent to a black image is discriminated. Whether the black image is formed using a black ink or a plurality of color inks C, M, and Y is determined in accordance with the discrimination result. When the black image is formed using the plurality of color inks, it is recorded using a repetitive pattern of two of C, M, and Y so as to prevent blurring with the color image, and to improve fixing characteristics by decreasing the total ejection amount.

摘要： An image is recorded on a recording medium by recording dots of a black ink and a color ink discharged onto the recording medium from a recording head. A boundary proximity-degree detecting circuit detects the degree of positional proximity, i.e., closeness, between the recording dots of the black ink and the recording dots of the color ink at the boundary between these dots. A dot substituting circuit performs, in accordance with the detected degree of positional proximity, substitution of the black pixels with recording dots of a color ink at the boundary. Thus, pixels of the image to be recorded are replaced with recording dots of a color ink by an extent which is determined based on the degree of positional proximity between the pixels of the different colors. A sharp black image can be obtained with minimized color mixing at the boundary between the black image region and the color region, regardless of the degree of positional proximity between these regions.
