20080211461 | CAPACITOR CHARGING CIRCUIT, FLASH UNIT, AND CAMERA - The present invention provides a flash discharging circuit for simplifying the charging of electric power in a capacitor. When energy discharged from a transformer for storing and discharging energy is charged in a main capacitor of the circuit, a detection voltage inputted to a first input terminal of a comparator so as to detect a primary current flowing through a primary winding of the transformer is compared with a reference voltage inputted to a second input terminal of the comparator. According to a result of the comparison, it is detected that a predetermined primary current flows through the primary winding of the transformer. When the primary current flowing through the primary winding of the transformer is turned off, the reference voltage is set to be lower than the detection voltage. | 09-04-2008 |
20130039583 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD, AND COMPUTER PROGRAM FOR CAUSING COMPUTER TO EXECUTE CONTROL METHOD OF IMAGE PROCESSING APPARATUS - Object recognition is executed by using, of feature data classified into a plurality of groups, only feature data belonging to a selected group. Hence, it is unnecessary to compare and refer to all feature data so that object recognition processing can be speeded up. | 02-14-2013 |

20110141080 | DISPLAY CONTROL APPARATUS AND METHOD OF CONTROLLING THE DISPLAY CONTROL DEVICE - A display control apparatus to drive a display panel to display an image and a control method of the display device. It is determined whether or not a number of different bits in a plurality of bits of display image signals that are to be continuously converted into analog signals are different from each other is equal to or more than a predetermined value. If it is determined that the number of different bits is equal to or more than the predetermined value, then the display image signal is modified so that the display panel is driven based on an analog signal converted from the modified display signal to display an image. | 06-16-2011 |
20110141380 | PROJECTOR, PROJECTOR CONTROL METHOD, AND PROJECTION SYSTEM - When images are projected in a superposing manner on a screen by a plurality of projectors, a controller of a projector obtains drive timing information of liquid crystal panels of the plurality of projectors and controls a drive timing of a drive unit on the basis of the obtained drive timing information so as to reduce a flicker of a display image. | 06-16-2011 |
20130120350 | ELECTROOPTICAL DISPLAY APPARATUS AND ELECTRONIC DEVICE - The electrooptical display apparatus includes pixels, and scan lines and data lines arranged in a matrix. The apparatus further includes pixel switching elements each enabling, in response to application of a selection voltage to one scan line, application of a pixel voltage to one pixel in a pixel row corresponding to the one scan line through one data line, a voltage producing part producing a sampling voltage that is to be supplied to the data lines and that monotonously changes while the selection voltage is applied to the scan line, a voltage sampling part sampling the pixel voltage from the sampling voltage, a sampling number detecting part detecting number of pixels for which a same voltage is sampled, and a controller lowering a frequency of sampling of the pixel voltage when the detected number is a predetermined number. | 05-16-2013 |
