Claim 3
Dependent Claim
78 words
An image recording apparatus including a plurality of recording heads each having a plurality of parallel recording elements arranged in a predetermined direction to move the recording heads in a direction different from the predetermined direction, thereby performing image recording, comprising means for correcting a value of an image signal recorded by the recording elements in accordance with a total sum of image signals recorded by a given recording element located at an end of the recording head.
Claim 4
Dependent Claim
78 words
An image recording apparatus including a plurality of recording heads each having a plurality of parallel recording elements arranged in a predetermined direction to move the recording heads in a direction different from the predetermined direction, thereby performing image recording, comprising means for correcting a value of an image signal recorded by the recording elements in accordance with a total sum of image signals recorded by a given recording element located at an end of the recording head.
Claim 5
Dependent Claim
97 words
An ink jet recording apparatus comprising: an ink jet recording means for line printing without overlap; subtraction means for subtracting a data to be printed to correct an image data; and discrimination means for discriminating as to whether or not a predetermined bit image data quantity corresponding to a boundary of the line printing is greater than a predetermined reference value, wherein said discrimination means determines that the image data quantity is greater than the reference value, said subtraction means operates to correct the image data, and the bit image is printed according to the corrected data.
Claim 6
Dependent Claim
97 words
An ink jet recording apparatus comprising: an ink jet recording means for line printing without overlap; subtraction means for subtracting a data to be printed to correct an image data; and discrimination means for discriminating as to whether or not a predetermined bit image data quantity corresponding to a boundary of the line printing is greater than a predetermined reference value, wherein said discrimination means determines that the image data quantity is greater than the reference value, said subtraction means operates to correct the image data, and the bit image is printed according to the corrected data.
Claim 7
Dependent Claim
