| 20100201865 | IMAGING METHOD FOR USE WITH VARIABLE CODED APERTURE DEVICE AND IMAGING APPARATUS USING THE IMAGING METHOD - Provided are an imaging method for use with a variable coded aperture filter and an imaging apparatus using the imaging method. The variable coded aperture filter includes a plurality of regulated patterns which may be properly selected, and an image obtained via a certain pattern of the variable coded aperture filter may be processed by a deconvolution method related to the certain pattern. The patterns in the variable coded aperture filter have different aperture degrees from each other so as to adjust an exposure amount, and accordingly, a subject which is extremely bright or extremely dark may be photographed and depth information and focus information may be obtained from the photographed image. Therefore, images of high image quality may be obtained in a large range of brightness variation. | 08-12-2010 |

| 20100045192 | METHOD FOR DRIVING LIGHT SOURCE, LIGHT SOURCE APPARATUS FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE LIGHT SOURCE APPARATUS - A method for driving a light source includes providing a first control voltage at a first level to a memory so that the memory performs a writing operation when an external control signal is received by a control voltage generating circuit, providing a second control voltage at a second level to the memory so that the memory prevents the writing operation when the external control signal is not received by the control voltage generating circuit, comparing a reference signal stored in the memory with a sensing signal based on an amount of light outputted from the light source to generate a driving signal, and providing the driving signal to the light source to compensate the amount of light outputted from the light source. | 02-25-2010 |
| 20100123695 | METHOD OF DRIVING LIGHT-EMITTING DIODES, BACKLIGHT ASSEMBLY FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE BACKLIGHT ASSEMBLY - A method of driving light-emitting diodes (LEDs), a backlight assembly for performing the method, and a display apparatus having the backlight assembly are disclosed for various embodiments. For example, the backlight assembly includes a light source unit and a light source controller. The light source unit includes red, green, and blue LEDs generating red, green, and blue light, respectively. The light source controller detects amounts of the red, green, and blue light, respectively, to compare the actual light amount ratio of the red, green, and blue light with the reference light amount ratio. The light source controller controls the red, green, and blue LEDs, respectively, so that an actual light amount ratio becomes substantially identical to a reference light amount ratio when the actual light amount ratio is not identical to the reference light amount ratio. | 05-20-2010 |
