Abstract

Abstract An image recording apparatus includes an input unit for inputting image data; a binarization unit for generating a plurality of binarized data by performing a plurality of binarization processings of the image data inputted from the input unit; and a recording unit for performing a plurality of recording process­ings relative to the same input image data by using the plurality of binarized data generated by the binarization unit.

Claim 6
Dependent Claim 25 words
An image recording apparatus according to claim 1, wherein said recording means performs a recording processing by using a printer of an ink jet type.
Claim 7
Dependent Claim 39 words
An image recording apparatus according to claim 2, wherein said binarization means performs the plurality of binarization processings while changing for the same input image data the matrix which is used in correcting errors generated at the binariza­tion processing.
Claim 8
Dependent Claim 35 words
An image recording apparatus according to claim 3, wherein said binarization means performs the plurality of binarization processing while changing for the same input image data the threshold value which is used for the binarization.
Claim 9
Dependent Claim 59 words
An image recording apparatus according to claim 1, wherein said input means inputs first and second color image data, said binarization means generates a plurality of binarized data by performing a plurality of binarization processings of said first color image data, and said recording means performs the plurality of recording processings in accordance with said plurality of binarized data.
Claim 10
Dependent Claim 39 words
An image recording apparatus according to claim 8, wherein said recording means performs a recording processing of said first color image data with a recording medium of lower density than that used for recording said second color image data.
Claim 11
Dependent Claim 34 words
An image recording apparatus according to claim 8, wherein said first color image data are cyan and magenta color image data, and said second color image data are yellow and black color image data.
Claim 12
Dependent Claim 114 words
An image recording apparatus comprising: input means for inputting first and second color image data; quantization means for quantizing said first and second color image data inputted from said input means; and recording means for recording an image with a recording medium corresponding to said inputted first and second color image data, in accordance with the processing results by said quantization means, wherein said recording means records an image with a recording medium having a different density level between said first and second color image data, and if an image is recorded with the recording medium having a lower density level, a plurality of recording processings are carried out for the same input data.
Claim 13
Dependent Claim 114 words
An image recording apparatus comprising: input means for inputting first and second color image data; quantization means for quantizing said first and second color image data inputted from said input means; and recording means for recording an image with a recording medium corresponding to said inputted first and second color image data, in accordance with the processing results by said quantization means, wherein said recording means records an image with a recording medium having a different density level between said first and second color image data, and if an image is recorded with the recording medium having a lower density level, a plurality of recording processings are carried out for the same input data.
Claim 14
Dependent Claim 33 words
An image recording apparatus according to claim 11, wherein said quantization means performs a binarization processing of said first and second color image data to correct error data generated during the binarization processing.
Claim 15
Dependent Claim 39 words
