Title:
IMAGE RECORDING DEVICE
Document Type and Number:
Japanese Patent JP3715349
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To correct the shift of scanning lines while restraining the occurrence of stripe-like noises by preventing the shift of scanning lines and simultaneously correcting the density dislocation of recording images in reference with the image element pattern of image signals.
SOLUTION: The auxiliary scanning position shift correction part 102 uses positional shift degree signals 159, 160, and corrects the shift in the auxiliary scanning direction of scanning lines composing recording images relative to the image signals while inputting image signals outputted from an image memory. The auxiliary scanning density shift correction means 103 corrects the density in the auxiliary scanning direction of the recording images accompanied by the correction of positional shift in the auxiliary scanning direction relative to the image signals outputted from the auxiliary scannig position shift detecting part 102. The main scanning position shift and density shift correction part 104 corrects each shift in the main scanning direction of the scanning lines composing the recording images relative to signals of the auxiliary scanning density shift correction part 103, and also converts the image signals into pulse width modulation signals and make them recording signals to the image recording part.
