20080204494 | INKJET RECORDING APPARATUS AND INKJET RECORDING METHOD - In an inkjet recording apparatus and an inkjet recording method, recording on a first unit region, of unit regions provided on a recording medium, is performed by scanning a recording head an even number of times over the first unit region, and recording on a second unit region adjacent to the first unit region is performed by scanning the recording head an odd number of times over the second unit region. The last of the scanning motions of the recording head over the first and second unit regions is made in a first direction. | 08-28-2008 |
20090002414 | INKJET PRINTING APPARATUS AND PRINTING METHOD - There is provided an inkjet printing apparatus which prints using a printhead for discharging ink by a plurality of scanning operations of the printhead including forward scanning and reverse scanning in a single area of a print medium. In the inkjet printing apparatus, the ink discharge amount is acquired for each unit area obtained by dividing the end area of the single area in the scanning direction. The acquired ink discharge amount of each unit area is compared with a predetermined threshold. The printing ratios of the plurality of scanning operations are controlled to set the printing ratio of the final scanning operation lower than the average one of the remaining scanning operations in a unit area where the ink discharge amount is larger than the predetermined threshold. | 01-01-2009 |
20090015614 | INK JET PRINT HEAD, INK JET PRINTING APPARATUS, AND METHOD FOR MANUFACTURING INK JET PRINT HEAD - The present invention is able to print high-grade images by reducing the adverse effect of misdirection of ink in the joining portion between adjacent nozzle lines. To achieve this, an ink jet print head includes a plurality of chips in each of which adjacent nozzle lines are formed. The relative positions of the chips are set depending on the amounts of misdirection of ink ejected from overlapping nozzles in the joining portion. | 01-15-2009 |
20090015849 | INKJET PRINTING APPARATUS, IMAGE PROCESSING METHOD AND IMAGE PROCESSING APPARATUS - Development of uneven gloss is reduced when printing mutually adjacent printing regions with pigment ink while overlapping boundary regions each other. A joint section and a non-joint section employ mutually different image processing such that a larger amount of ink having a relatively higher gloss level is used in the joint section as compared to the non-joint section. In this way, it is possible to uniform gloss impression between the non-joint section and the joint section and thereby to reduce uneven gloss. | 01-15-2009 |
20090040550 | DATA GENERATION APPARATUS, PRINTING APPARATUS AND DATA GENERATION METHOD - When a feeding amount for multi-pass printing is changed, the purpose related to an image quality using a binary data generation pattern can still be attained by, for example, a density pattern method. Specifically, a multi-pass printing mode is identified, and a density pattern selection matrix associated with a cycle of binary data generation is selected in accordance with the selected printing mode. That is, a density pattern selection matrix employed for binary data generation using a density pattern is changed to a size corresponding to the feeding amount designated by the selected printing mode. Thereby, a phenomenon that a unit used for image processing to gain a predetermined purpose related to an image quality does not match a unit area used for a printing operation is avoided, and an image printing purpose using a binary data generation pattern can be appropriately attained. | 02-12-2009 |

20080310292 | OPTICAL DISK, OPTICAL DISK RECORDING AND REPRODUCING APPARATUS, METHOD FOR RECORDING, REPRODUCING AND DELETING DATA ON OPTICAL DISK, AND INFORMATION PROCESSING SYSTEM - A recording type optical disk on which data is recordable includes a data recording and reproducing area for recording data therein and reproducing data therefrom, and a read-only disk identification information area for recording disk identification information for identifying the optical disk therein. In the optical disk, the disk identification information is formed by removing a reflection film that is formed on the optical disk in a strip shape. The disk identification information includes an inherent disk identifier for each optical disk, and the data recording and reproducing area includes an area for recording encrypted data therein. The encrypted data is encrypted by using information including the disk identification information for identifying the optical disk as a key. | 12-18-2008 |
20090092030 | Optical disk device - Provided is an optical disk device to output a reproduction signal to reproduce an optical disk, including: a light output circuit to output light having a high frequency superimposed thereon; a first light receiving circuit to receive the light to output a first voltage corresponding to an amount of the light; a second light receiving circuit to output a second voltage corresponding to an amount of reflected light from the optical disk; an arithmetic circuit to output a calculation result based on a difference between the first voltage and the second voltage; and a reproduction signal generating circuit to control one of the first voltage and the second voltage based on the calculation result to generate the reproduction signal to reproduce the optical disk. | 04-09-2009 |

20130256508 | PHOTOELECTRIC CONVERSION DEVICE - A photoelectric conversion device is provided that has high linearity of output current to illuminance and is applicable to illumination sensors. The photoelectric conversion device outputs appropriate current by complementing first current, which is generated in response to incident light, with complementary current. The complementary current is generated based on second current flowing in response to the light. The second current is generated by a device having the same element area as that of a device that generates the first current. When the second current flows, the complementary current is generated based on a direction of the second current and is then added to the first current. | 10-03-2013 |
