Abstract
Means for detecting scanning positions of first and second recording heads is provided for detecting that the first recording head is opposed to a recording inhibition area (in which an imaging material is not mounted) on a drum 1, based on an output from the detection means. While the recording head is in the recording inhibition area, correction data for the second recording head is read from a correction data memory and transferred to a submemory in an FPGA for image processing. The second recording head reads the correction data from the submemory. Correction data can be read in parallel.
Claims22
An image recording system for recording an image by scanning an imaging material on the basis of image data, comprising:
- a holding element for holding the imaging material on a substantially cylindrical holding surface;
- a plurality of recording heads individually movable on a common moving path along an axial direction of said holding surface and capable of individually scanning said imaging material;
- a compensation data holding element for holding compensation data compensating for a scanning error from a reference scanning state with respect to said holding surface;
- and
- a regulation element for regulating scanning positions of said plurality of recording heads on said imaging material while employing the same part of said compensation data for said plurality of recording heads for the same scanning position.

- a holding element for holding the imaging material on a substantially cylindrical holding surface;
- a plurality of recording heads movable on a common moving path along an axial direction of said holding surface and capable of individually scanning said imaging material;
- a compensation data holding element for holding compensation data compensating for a scanning error from a reference scanning state with respect to said holding surface;
- and
- a regulation element for regulating scanning positions of said plurality of recording heads on said imaging material while employing the same part of said compensation data for said plurality of recording heads for the same scanning position, wherein
- said compensation data holding element comprises
- a data memory for storing the compensation data for compensating for scanning positions of the recording heads on said imaging material, and
- said regulation element comprises:
- a submemory for temporarily storing said compensation data,
- a scanning position detection element for detecting the scanning positions of the recording heads,
- an element for detecting that at least one of said plurality of recording heads is in a recording inhibition area on the basis of a signal from said scanning position detection element, to read the compensation data for the remainder of the plurality of recording heads from said data memory thereby to store the compensation data in said submemory while said one of the recording heads is in said recording inhibition area, and
- a correction element for reading the compensation data in parallel from said data memory and the submemory to correct the scanning positions of the plurality of recording heads on the imaging material.
An image recording system for recording a plurality of images on a plurality of imaging materials respectively on the basis of a plurality of image data corresponding to each other, comprising:
- a holding element for holding said plurality of imaging materials in parallel on a substantially cylindrical holding surface;
- a plurality of recording heads arranged in parallel opposite to said holding surface;
- an image data supply element for supplying said plurality of image data to said plurality of recording heads respectively;
- a moving element for individually moving said plurality of recording heads along an axial direction of said holding surface;
- a moving signal supply element for supplying moving signals for said plurality of recording heads respectively to said moving element;
- and
- a regulation element for at least partially regulating said plurality of image data and said moving signals, thereby to compensate for a geometric mismatch between the scans of said plurality of imaging materials respectively by said plurality of recording heads.
