20140362279 | FOCUS DETECTION APPARATUS AND METHOD, METHOD OF CONTROLLING FOCUS DETECTION APPARATUS, AND IMAGE CAPTURING APPARATUS - A focus detection apparatus comprises: an image sensing unit including photoelectric conversion elements for each microlens, with the microlenses being two-dimensionally arranged; a generation unit configured to generate a first signal pair having a first resolution from signals of a first area of the image sensing unit which corresponds to a predetermined focus detection area and generate a second signal pair having a second resolution lower than the first resolution from signals of a second area which corresponds to the predetermined focus detection area and is wider than the first area; a focus detection unit configured to perform phase difference focus detection processing based on at least one of the first and second signal pairs; and a recording image generation unit configured to generate a recording image from a signal output from the image sensing unit. | 12-11-2014 |
20150062389 | FOCUS DETECTION APPARATUS, CONTROL METHOD THEREFOR, AND IMAGE CAPTURE APPARATUS - A plurality of image signals for focus detection are generated from combined signals obtained by combining output signals of a pixel in which a plurality of photoelectric conversion areas obtained by dividing are arranged in a predetermined direction, in units of the photoelectric conversion areas, and the defocus amount is detected based on a correlation amount between the plurality of image signals. The combined signals are generated for each pixel block, for a plurality of pixel block lines in which pixel blocks each having a predetermined size are arranged in the predetermined direction. The pixel data amount for focus detection can be effectively reduced by, in the combining, making combining central points of signals, in the plurality of pixel block lines, shifted relative to each other or phases of positions of the pixel blocks different from each other. | 03-05-2015 |

20090006949 | INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD - An information processing apparatus for processing documents of multiple kinds generated by applications of multiple kinds includes a data processing unit configured to process the documents of multiple kinds; a determining unit configured to execute a validity period management program in response to a request to the data processing unit to process one document among the documents of multiple kinds to determine whether the request is within a validity period associated with a content item in the document; and a switching unit configured to switch the content item that is referred to and that is to be processed by the data processing unit between when the determining unit determines that the content is not within the validity period and when the determining unit determines that the content is within the validity period. | 01-01-2009 |
20090257086 | IMAGE FORMING APPARATUS AND CONTROL METHOD THEREFOR - An image forming apparatus that permits alteration of print data during execution of a print job for the print data stored in an external apparatus. Upon generation of an interruption job during execution of the print job for the print data, an MFP suspends the print job. If free space in a memory is less than the capacity required for execution of the interruption job, the MFP erases the print data in the memory and carries out the interruption job. When the interruption job is completed, the MFP transmits to another MFP a request for transmission of copy data of the print data and restarts the print job for the copy data of the print data transmitted from the other MFP in response to the transmission request. | 10-15-2009 |
20100208293 | COMMUNICATION APPARATUS, CONTROL METHOD, AND STORAGE MEDIUM - A control method for controlling a communication apparatus used for transmitting a file with efficiency and reliability according to a time required for the conversion processing when a file as a transmission object is converted into transmission data, and the control method includes converting an input file into transmission data, transmitting the transmission data obtained by the conversion processing, measuring a time required for the conversion processing, and controlling the communication apparatus based on the measured time so that, if a file whose time required for the conversion processing is greater than a predetermined value is to be transmitted, communication with the destination is started and the transmission data is transmitted after the conversion processing is executed, and if a file whose time required for the conversion processing is not greater than the predetermined value is to be transmitted, the conversion processing is executed after the communication with the destination is started, and the transmission data obtained by the conversion processing is transmitted. | 08-19-2010 |
