Abstract
An image recording device has: a recording head which has plural channels arranged rectilinearly, and which can illuminate light beams; a line memory storing image data, which is based on a number of main scan lines of one main scan by the recording head, as one unit; and a buffer storing, for each of the respective channels, data stored in the line memory. At a look up table, channel reshuffling control is executed, and pixel offset amounts of lines corresponding to channels of reshuffle destinations are added, and data is transferred to the buffer. When a channel order is reshuffled due to movement of the recording head, reshuffling control is carried out at the table in accordance with an order at a time of reshuffling, and at a time of transferring the image data from the line memory to the buffer.
Claims20
An image recording device comprising:
- a recording head having light sources of plural channels arranged rectilinearly, and able to simultaneously illuminate light beams from the respective channels on the basis of input image data, and able to main scan and subscan the light beams onto a recording material in order to record an image;
- a line memory storing the input image data, with image data based on a number of main scan lines of one main scan by the recording head being one unit;
- a buffer storing, for each of the respective channels, the input image data stored in the line memory;
- a transfer control device shifting, in a main scanning direction, image data read out from the line memory and transferring the image data to the buffer, on the basis of pixel offset amounts in the main scanning direction between the respective main scan lines;
- and
- an image data reshuffling control device reshuffling, in units of channels and on the basis of an order of the respective channels of the recording head, image data to be transferred to the buffer from the line memory.

An image recording method using an image recording device having:
- (a) a recording head having light sources of plural channels arranged rectilinearly, and able to simultaneously illuminate light beams from the respective channels on the basis of input image data, and able to main scan and subscan the light beams onto a recording material in order to record an image;
- (b) a line memory storing the input image data, with image data based on a number of main scan lines of one main scan by the recording head being one unit;
- and (c) a buffer storing, for each of the respective channels, the input image data stored in the line memory,
- said method comprising the steps of:
- on the basis of pixel offset amounts in a main scanning direction between the respective main scan lines, shifting, in the main scanning direction, image data read out from the line memory and transferring the image data to the buffer;
- and
- reshuffling, in units of channels and on the basis of an order of the respective channels of the recording head, image data to be transferred to the buffer from the line memory.
