Abstract
Official abstract text for this publication.
A liquid droplet ejecting apparatus includes (n+m) nozzle rows in each of which a plurality of nozzles through which liquid droplets are ejected onto a printing medium are arranged; a nozzle row driving data generation portion configured to generate n sets of nozzle row driving data for the (n+m) rows of nozzles each for driving a corresponding one of the (n+m) nozzle rows; and a nozzle row driving data conversion portion configured to convert the generated n sets of nozzle row driving data that are associated with the (n+m) rows of nozzle row driving data into (n+m) sets of nozzle row driving data each of which is associated with a corresponding one of the (n+m) rows of nozzle row driving data.
First claim
Opening claim text (preview).
What is claimed is: 1. A nozzle row driving data conversion apparatus configured to convert n sets of nozzle row driving data for (n+m) rows of nozzles into (n+m) sets of nozzle row driving data for the (n+m) rows of nozzles. 2. The nozzle row driving data conversion apparatus according to claim 1 , wherein the n sets of nozzle row driving data for the (n+m) rows of nozzles includes nozzle row driving data resulting from dividing m rows of nozzle row driving data into n blocks. 3. The nozzle row driving data conversion apparatus according to claim 1 , wherein the n sets of nozzle row driving data for the (n+m) rows of nozzles includes nozzle row driving data resulting from dividing each of the (n+m) rows of nozzle row driving data into n blocks. 4. The nozzle row driving data conversion apparatus according to claim 1 , wherein the nozzle row driving data conversion apparatus includes a programmable logic device. 5. A liquid droplet ejecting apparatus comprising: (n+m) nozzle rows including a plurality of nozzles through which liquid droplets are ejected onto a printing medium; and a nozzle row driving data conversion portion configured to convert n sets of nozzle row driving data for the (n+m) rows of nozzles, the data being used in driving the nozzle rows, into (n+m) sets of nozzle row driving data for the (n+m) rows of nozzles. 6. The liquid droplet ejecting apparatus according to claim 5 , wherein the n sets of nozzle row driving data for the (n+m) rows of nozzles includes nozzle row driving data resulting from dividing m rows of nozzle row driving data into n blocks. 7. The liquid droplet ejecting apparatus according to claim 5 , wherein the n sets of nozzle row driving data for the (n+m) rows of nozzles includes nozzle row driving data resulting from dividing each of the (n+m) rows of nozzle row driving data into n blocks. 8. The liquid droplet ejecting apparatus according to claim 5 , wherein the nozzle row driving data conversion portion includes a programmable logic device.
