| 20090060323 | NOISE REMOVAL DEVICE, NOISE REMOVAL METHOD, AND COMPUTER READABLE RECORDING MEDIUM - A noise removal device that removes noise from an image signal includes: a separation unit that separates the image signal into at least two subband signals; a parameter setting unit that sets a plurality of coring ranges in relation to at least one of the subband signals; and a coring unit that performs coring processing on the basis of the plurality of coring ranges. | 03-05-2009 |
| 20090091643 | Image-Acquisition Apparatus - An image-acquisition apparatus is provided, including a correction-coefficient calculating unit | 04-09-2009 |
| 20090167901 | IMAGE-ACQUISITION APPARATUS - The object is to provide a uniform impression of noise for an entire image signal by performing grayscale conversion and noise reduction in a balanced manner. The signal processing unit performs first signal conversion on an image signal from an image-acquisition device and transfers the processed image signal to a correction-coefficient calculation unit. The correction-coefficient calculation unit calculates, on the basis of the image signal from the signal processing unit, an area correction coefficient for each area used for grayscale conversion of each area. A noise reducing unit uses the area correction coefficients calculated by the correction-coefficient calculation unit to perform noise reduction on the image signal from the image-acquisition device and transfers the processed signal to the signal processing unit. The signal processing unit performs grayscale conversion on the areas of the noise-reduced image signal and transfers the signal to the compressing unit using the area correction coefficients. | 07-02-2009 |
| 20100027885 | COMPONENT EXTRACTION/CORRECTION DEVICE, COMPONENT EXTRACTION/CORRECTION METHOD, STORAGE MEDIUM AND ELECTRONIC EQUIPMENT - Provided is a component extraction/correction device, comprising: a decomposition unit that decomposes an original image signal into a plurality of frequency bands to generate a plurality of band signals; an extraction unit that extracts a skeleton component from among a plurality of components constituting the band signal; a first correction unit that corrects the extracted skeleton component by using the band signal and one component other than the skeleton component among the plurality of components; and a second correction unit that corrects the one component by using the corrected skeleton component and the band signal. | 02-04-2010 |
