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

20080211936	IMAGE SENSING APPARATUS, IMAGE PROCESSING APPARATUS, AND CONTROL METHOD THEREFOR FOR RELAXING A RED-EYE EFFECT - This invention makes it possible to execute photography with a sufficient red-eye relaxation effect. To do this, in this invention, the amount of a red eye is detected on the basis of a signal obtained by reading an object image under light projection by a light projection unit. The light projection by the light projection unit is controlled on the basis of the detection result.	09-04-2008

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
