20150197687 | Photoluminescence-Enhanced Sandwich Structure of Luminescent Films and Method - A sandwich structure for enhancement of photoluminescence (PL) from luminescent films and the corresponding preparation method are disclosed. The sandwich structure comprises a support, a luminescent film grown on the support, and a close-packed dielectric microsphere monolayer deposited onto the luminescent film. The microspheres have high transmittance excitation light and emitted light, respectively. The low price of dielectric microspheres is beneficial to industrial applications. The stable chemical properties of dielectric microspheres make PL enhanced in a long term. Both metal and non-metal materials can be used as the support in the sandwich structure. These features significantly improve the technique of PL enhancement for luminescent films. | 07-16-2015 |

20110157583 | METHOD OF CALIBRATING SENSITIVITY GAIN - The present invention is directed to a method of calibrating sensitivity gain. In a preview mode, an imaging device is calibrated by a standard light source, therefore obtaining standard sensitivity gain of the preview mode. In a capture mode, the imaging device is calibrated by the standard light source, therefore obtaining standard sensitivity gain of the capture mode. A gain ratio of the standard sensitivity gain of the capture mode to the standard sensitivity gain of the preview mode is determined, and is then used to deduce the exposure parameters of the capture mode according to the exposure parameters of the preview mode. | 06-30-2011 |
20110157584 | METHOD OF CALIBRATING A LIGHT SOURCE - The present invention is directed to a method of calibrating a light source. In one embodiment, a standard image sensor is used to capture emitted light of a standard and a to-be-calibrated light source in order to obtain a standard and a nonstandard image, respectively. A standard and a nonstandard luminance response are generated according to the standard and the nonstandard image, respectively. The to-be-calibrated light source is adjusted until the nonstandard luminance response is about equal to the standard luminance response. In another embodiment, the standard image sensor is used to capture emitted light of the standard and the to-be-calibrated light source. According to sampled outputs of the standard image sensor, a standard and a nonstandard chrominance response are respectively generated, which are used to compensate an image sensor under test. | 06-30-2011 |
20120195518 | IMAGE COMPENSATION METHOD AND SYSTEM - The present invention is directed to an image compensation method and system. A first frame of a plurality of first pixels is provided. A compensation step is performed on the first pixels to generate a second frame of a plurality of second pixels, wherein any two of the adjacent second pixels have a same distance therebetween. A frame resizing step is performed before and/or after the compensation step. | 08-02-2012 |

20150117770 | IMAGE PROCESSING METHOD, ELECTRONIC DEVICE, ELECTRONIC DEVICE READABLE STORAGE MEDIUM AND PROGRAM APPLIED IN ELECTRONIC DEVICE - An image processing method comprises: receiving a first image; setting at least one first region on the first image, where the first image comprises at least one line; calculating a first average value of the first region; performing computation on the first image with a first parameter set to generate a second image; setting a second region of the second image according to the first region, and calculating a second average value of the second region; calculating a difference between the first average value and the second average value; and determining whether to replace the first image with the second image according to the difference. | 04-30-2015 |
20150187079 | ELECTRONIC DEVICE - An electronic device comprises a computing module and a storing module. The computing module receives a first image having a first region with two spots, determining whether a first interval between the spots of the first region is larger than a threshold, computing the first image with a parameter of a parameter set for obtaining a second image having a second region corresponding to the first region with two spots if the first interval is larger than the threshold, and determining whether a second interval between the spots of the second region is larger than the threshold. The storing module records the parameter, if the second interval is smaller than or equal to the threshold. | 07-02-2015 |
