| مستخلص: | A recording apparatus for discharging ink from a recording head arraying a plurality of nozzles to execute recording of an image includes a drive unit configured to form a group with a defined number of nozzles so as to include an adjacent nozzle in a different block and to execute time-division driving of the block according to a driving order corresponding to a recording mode, and a recording control unit configured to execute scan recording to a recording medium in a first recording mode or a second recording mode. Each pass of scan recording in the second recording mode is executed using nozzles smaller in number than a number of nozzles used to execute each pass of scan recording in the first recording mode. The recording apparatus further includes a driving control unit configured to control the drive unit wherein a drive interval of an adjacent nozzle in the same group corresponding to the first recording mode is larger than a drive interval of an adjacent nozzle in the same group corresponding to the second recording mode. |

| Claim: | 1. A recording apparatus for discharging ink from a recording head arraying a plurality of nozzles to execute recording of an image, the recording apparatus comprising: a drive unit configured to form a group with a defined number of nozzles, wherein two nozzles, adjacent to each other within said group, each belong to a different block, and the drive unit is configured to execute time-division driving of the blocks in the group according to a driving order corresponding to a recording mode; a recording control unit configured to execute scan recording to a recording medium in a first recording mode or a second recording mode, wherein each pass of scan recording in the second recording mode is executed using nozzles smaller in number than a number of nozzles used to execute each pass of scan recording in the first recording mode; a driving control unit configured to control the drive unit, wherein when the first recording mode is executed, a drive interval between the two nozzles, each belonging to a different block and both belonging to the same group, is larger than a drive interval between said two nozzles, when the second recording mode is executed; and a scanning control unit configured to execute the first recording mode that performs scan recording to the recording medium at a predetermined speed or the second recording mode that performs scan recording to the recording medium at a speed lower than the predetermined speed. |
| Claim: | 2. The recording apparatus according to claim 1 , wherein the recording control unit executes the first recording mode that performs a predetermined number of scan recording passes to the same area of the recording medium to complete an image or the second recording mode that performs to the same area of the recording medium a number of scan recording passes which is larger than the predetermined number of scan recording passes performed in the first recording mode, to complete an image. |
| Claim: | 3. The recording apparatus according to claim 1 , further comprising: a driving control unit configured to control the drive unit so as to further divide one group into a plurality of subgroups to sequentially drive nozzles contained in the subgroups, for each subgroup in the second recording mode. |
| Claim: | 4. The recording apparatus according to claim 1 , further comprising: a setting unit configured to set the first recording mode or the second recording mode. |
| Claim: | 5. A method for discharging ink from a recording head arraying a plurality of nozzles to execute recording of an image, the method comprising: forming a group with a defined number of nozzles, wherein two nozzles, adjacent to each other within said group, each belong to a different block, and executing time-division driving of the blocks in the group according to a driving order corresponding to a recording mode; executing scan recording to a recording medium in a first recording mode or a second recording mode, wherein each pass of scan recording in the second recording mode is executed using nozzles smaller in number than a number of nozzles used to execute each pass of scan recording in the first recording mode; and controlling the time-division driving wherein when the first recording mode is executed, a drive interval between the two nozzles, each belonging to a different block and both belonging to the same group, is larger than a drive interval between said two nozzles, when the second recording mode is executed; executing the first recording mode that performs scan recording to the recording medium at a predetermined speed or the second recording mode that performs scan recording to the recording medium at a speed lower than the predetermined speed. |
