Abstract
An image recording apparatus acquires, from image data, gradation information in a region corresponding to a connected portion at which recording chips are overlapped with each other, sets, based on the acquired gradation information, control information for controlling recording rates of respective recording elements of a plurality of recording chips that are connected in an overlapped state, and according to the set control information, generates, from the image data, dot data for respective recording elements of the plurality of recording chips that are connected in the overlapped state.
Claims16
An image recording apparatus configured to record an image on a recording medium using a recording head having a plurality of recording chips that are equipped with recording element arrays, wherein the recording chips are arranged in a direction parallel to the recording element arrays, wherein a part of the image on the recording medium is formed by overlapping images recorded by connected portions that are parts of the different recording tips, the image recording apparatus comprising:
- an acquisition unit configured to acquire, from image data, gradation information in a region corresponding to a connected portion;
- a setting unit configured to set, based on the gradation information, control information for controlling recording rates of respective recording elements of the plurality of recording chips;
- and
- a generation unit configured to, according to the set control information, generate, from the image data, dot data for respective recording elements of the plurality of recording chips.
An image processing method for generating dot data for an image recording apparatus configured to record an image on a recording medium using a recording head having a plurality of recording chips that are equipped with recording element arrays, wherein the recording chips are in a direction parallel to the recording element arrays, wherein a part of the image on the recording medium is formed by overlapping images recorded by connected portions that are parts of the different recording tips, the image processing method comprising:
- acquiring, from image data, gradation information in a region corresponding to a connected portion;
- setting, based on the gradation information, control information for controlling recording rates of respective recording elements of the plurality of recording chips;
- and
- according to the set control information, generating, from the image data, dot data for respective recording elements of the plurality of recording chips.
A non-transitory computer-readable storage medium storing a program for causing an image recording apparatus to record an image on a recording medium using a recording head having a plurality of recording chips that are equipped with recording element arrays, wherein the recording chips are in a direction parallel to the recording element arrays, wherein a part of the image on the recording medium is formed by overlapping images recorded by connected portions that are parts of the different recording tips, the program comprising:
- computer-executable instructions for acquiring, from image data, gradation information in a region corresponding to a connected portion;
- computer-executable instructions for setting, based on the gradation information, control information for controlling recording rates of respective recording elements of the plurality of recording chips;
- and
- computer-executable instructions for, according to the set control information, generating, from the image data, dot data for respective recording elements of the plurality of recording chips.
