Patent application numberDescriptionPublished
20090322891SIGNAL PROCESSING APPARATUS, SIGNAL PROCESSING METHOD, PROGRAM AND RECORDING MEDIUM - A signal processing apparatus includes: an input unit receiving a first image generated by a first camera and higher-resolution second images generated by a plurality of second cameras; a similar portion detecting unit detecting a similar portion between part of a subject included in the first image and a subject included in each of the second images; an image synthesizing unit pasting the second images at positions corresponding to the detected similar portions within the first image to generate a synthesized image; an imaging area detecting unit detecting an area, for which image information is insufficient in the first image and is difficult to complement by the second cameras, as a non-imageable area from the synthesized image; and a camera parameter calculation unit changing a camera parameter for controlling the second camera that captures the second image by which the image information insufficient in the first image is complemented.12-31-2009

20090274493AIR DISCHARGING APPARATUS AND IMAGE FORMING APPARATUS - An air discharging apparatus to discharge pressurized air at a predetermined timing is disclosed. The disclosed air discharging apparatus includes an air pump including a cylinder and a piston configured to reciprocate in the cylinder; an opening and closing member provided at an air discharge opening of the air pump and configured to open and close the air discharge opening; and a switching mechanism providing mechanical coupling between the piston and the opening and closing member. The mechanical coupling keeps the opening and closing member in a closed state until the piston reaches a predetermined position in a compression stroke and switches the opening and closing member to an opened state when the piston reaches the predetermined position.11-05-2009

20100046124Boost DC-DC converter control circuit and boost DC-DC converter having protection circuit interrupting overcurrent - A boost DC-DC converter control circuit includes a transistor which is disposed between an input terminal and an output terminal of a boost DC-DC converter, and which is configured to interrupt an overcurrent between the two terminals. The control circuit includes an amplifier configured to amplify a difference between a voltage of the transistor on a side of the input terminal and a voltage of the transistor on a side of the output terminal, and a comparator configured to compare an output voltage from the amplifier with a predetermined reference voltage. On- and off-states of the transistor are controlled in response to an output voltage from the comparator.02-25-2010

20080291498IMAGE PROCESSING METHOD AND IMAGE FORMING DEVICE - An image processing method is provided. The image processing method includes: generating profiles for color reproduction, classified for each of recording papers, from at least one of particular characteristic data of the each recording paper, which is generated on the basis of factors that affect color reproduction and particular generation information of the each recording paper, which is obtained by printing plural patch patterns at the recording paper and performing colorimetry of the printed patch patterns; and when implementing basic extraction control for extracting a profile that matches in at least one of the characteristic data and the generation information, if no profile that matches in at least one of the characteristic data and the generation information is extracted, extracting a profile that approximates in accordance with a pre-specified order of priority determination procedure to be a candidate.11-27-2008
20100092080SYSTEM AND METHOD FOR MAKING A CORRECTION TO A PLURALITY OF IMAGES - An image processing apparatus includes a feature amount recognition unit that recognizes a feature amount of each of plural pieces of image data, and a processing reference extraction unit that extracts a processing reference for image correction to be made to the plural pieces of image data from the feature amount recognized by the feature amount recognition unit.04-15-2010
20100092090SYSTEM AND METHOD FOR MAKING A CORRECTION TO A PLURALITY OF IMAGES - An image processing apparatus includes a feature amount recognition unit that recognizes a feature amount of each of plural pieces of image data, and a processing reference extraction unit that extracts a processing reference for image correction to be made to the plural pieces of image data from the feature amount recognized by the feature amount recognition unit.04-15-2010
20100321747IMAGE PROCESSING APPARATUS, IMAGE FORMING SYSTEM, IMAGE PROCESSING METHOD AND COMPUTER READABLE MEDIUM - The image processing apparatus includes: a color conversion unit color-converting an image signal of a first color space into that of a second color space by using a color conversion characteristic defining a correspondence relationship between the image signals of the first and second color spaces; an adjustment unit adjusting the image signal of the second color space, in accordance with a change in the color conversion characteristic; a correction unit correcting a conversion factor group for adjustment used when the image signal of the second color space is adjusted; and a judgment unit judging whether the conversion factor group needs to be corrected, on the basis of a color measurement result of a second color sample group including color samples the number of which is smaller than that of color samples in a first color sample group on which color measurement is performed to create the conversion factor group.12-23-2010
20100328688IMAGE PROCESSING APPARATUS, IMAGE FORMING SYSTEM, IMAGE PROCESSING METHOD AND COMPUTER READABLE MEDIUM - The image processing apparatus includes: a color conversion unit color-converting an image signal of a first color space into that of a second color space with a color conversion characteristic defining a correspondence relationship between the image signals; an adjustment unit adjusting the image signal of the second color space with adjustment conversion factor groups that is for adjusting it in accordance with a change in the color conversion characteristic, and is set for respective types of sheets on which an image is to be printed according to the image signal of the second color space; a calculation unit calculating the adjustment conversion factor groups; a memory storing an associating factor group associating, with each other, the adjustment conversion factor groups; and an update unit updating the adjustment conversion factor groups according to the calculated adjustment conversion factor group of one sheet and the stored associating factor group.12-30-2010
