| 20090290205 | OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS USING THE SAME - An optical deflector of the present invention includes a movable mirror and torsion bars supporting the mirror and formed integrally with the mirror. The mirror reciprocatingly vibrates to reflect a light beam to thereby deflect it. The mirror is curved in the form of an arch in a section including at least the torsion bars. The mirror deforms little during vibration even if it is thin. Small power can cause such a thin mirror to vibrate with a large amplitude. | 11-26-2009 |
| 20100060712 | SURFACE-EMISSION LASER ARRAY, OPTICAL SCANNING APPARATUS AND IMAGE FORMING APPARATUS - A surface-emission laser array comprises a plurality of surface-emission laser diode elements arranged in the form of a two-dimensional array, wherein a plurality of straight lines drawn perpendicularly to a straight line extending in a first direction from respective centers of the plurality of surface emission laser diode elements aligned in a second direction perpendicular to the first direction, are formed with generally equal interval in the first direction, the plurality of surface-emission laser diode elements are aligned in the first direction with an interval set to a reference value, and wherein the number of the surface-emission laser diode elements aligned in the first direction is smaller than the number of the surface-emission laser diode elements aligned in the second direction. | 03-11-2010 |

| 20080239086 | DIGITAL CAMERA, DIGITAL CAMERA CONTROL PROCESS, AND STORAGE MEDIUM STORING CONTROL PROGRAM - A digital camera that includes an imaging component, a display component, a characteristic information extraction component, an assistance image determination component and a control component. The imaging component images a subject and outputs image information representing the subject. The display component implements display on the basis of the image information outputted from the imaging component. The characteristic information extraction component extracts characteristic information representing a pre-specified characteristic from the image information. The assistance image determination component determines an assistance image, for assisting a determination of composition when the subject is to be photographed, on the basis of a result of extraction by the characteristic information extraction component. The control component controls the display component such that the assistance image determined by the assistance image determination component is displayed superimposed with the subject that is being displayed by the display component. | 10-02-2008 |
