20110085052 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An object is to suppress a false color and moire that occur in a high-frequency region. Color interpolation circuits of a color-difference signal generating circuit separate an image signal obtained from an image pickup device, in which a plurality of color filters are arranged in a predetermined pattern and in which pixels corresponding to the respective color filters are provided, into image signals of the respective color filters (R, G1, G2, and B), and perform an interpolation process on the image signals of the respective color filters. Then, a false color determining circuit determines whether a target region is a high-frequency region on the basis of at least any of slopes of image signals of the G1 filter and the G2 filter and a difference between the image signals of the G1 filter and the G2 filter in the target region. | 04-14-2011 |
20120281123 | IMAGE PROCESSING APPARATUS AND CONTROL METHOD FOR IMAGE PROCESSING APPARATUS - The present invention provides an image processing apparatus for detecting, from image data generated by an image sensor constituted by a plurality of pixels, a signal from a defective pixel of the image sensor, including first determination means for obtaining a first determination value indicating a magnitude of a difference in signal level between a pixel of interest and a plurality of pixels located in the neighborhood of the pixel of interest, second determination means for obtaining a second determination value indicating a width of distribution of the difference in signal level between the pixel of interest and the plurality of pixels located in the neighborhood of the pixel of interest, and detection means for detecting whether or not the signal from the pixel of interest is a defective pixel signal, using the first determination value and the second determination value. | 11-08-2012 |
20130038762 | IMAGE PROCESSING APPARATUS AND CONTROL METHOD FOR THE SAME - A direction in which pixels highly correlated with a signal value of a pixel of interest exist is determined by using both signal values of a plurality of pixels of different colors from the pixel of interest and of a plurality of pixels of the same color as the pixel of interest among a plurality of peripheral pixels of the pixel of interest, and obtains pixel correction values corresponding to the respective directions. Weighted addition of those pixel correction values is performed in accordance with the degree to which the pixel of interest is of an achromatic color, and the pixel correction value for the pixel of interest is thus obtained. | 02-14-2013 |
20130038773 | IMAGE PROCESSING APPARATUS AND CONTROL METHOD FOR THE SAME - When determining a direction in which pixels highly correlated with a defective pixel exist, it is determined whether the direction is the horizontal or vertical direction or the oblique direction from signal values of peripheral pixels of the same color as the defective pixel. On the other hand, one of the vertical direction and the horizontal direction and one of a plurality of predetermined oblique directions are determined from signal values of peripheral pixels of different colors from the defective pixel, and one direction is selected as the final direction determination result according to a determination result obtained by using pixels of the same color. | 02-14-2013 |
20130128082 | IMAGE-PICKUP APPARATUS AND METHOD OF DETECTING DEFECTIVE PIXEL THEREOF - An image pickup apparatus which can detect, when pixels have a structure in which part of electrical construction is shared therebetween, a defective pixel by taking into account a high possibility of the other pixels sharing the part of electrical construction becoming defective pixels, thereby making it possible to obtain an excellent image. A ROM stores in advance position information on each defective pixel. A defective pixel-detecting section detects a new defective pixel on which position information is not stored by the storage unit, from the pixels forming each pixel group, by performing one of different types of defective pixel detection processing. A system controller causes the defective pixel-detecting section to execute one of the different types of detection processing, according to the number of defective pixels which are included in each pixel group and on which the position information is stored in the storage unit. | 05-23-2013 |
20130222641 | IMAGE CAPTURING APPARATUS AND CONTROL METHOD THEREOF - In an image capturing apparatus, a first image data is stored in a first storage; second image data of a low resolution is generated by the first reducing; enlarged image data is generated; low resolution image data is generated from the first image data through processing that is different from that performed by the first reducing, the low resolution image data have the same pixel count as the first image data and a lower resolution than that of the first image data; one of first image processing in which the first image data is combined with the enlarged image data or second image processing in which the first image data is combined with the low resolution image data is executed; and the processing is switched between the first image processing and the second image processing, according to a shooting operation. | 08-29-2013 |
20130243318 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An image processing apparatus comprises means for generating, from first-resolution image data including signals according to a plurality of color filters, second-resolution image data including signals according to the plurality of color filters at a resolution lower than the first-resolution image data; means for generating luminance signals from the signals according to the plurality of color filters of the second-resolution image data; means for storing image data including the luminance signals generated from the second-resolution image data; means for generating image data, which includes signals according to the plurality of color filters as many as the number of pixels of the first-resolution image data, from the stored image data and includes the luminance signals; and means for combining the signals according to the plurality of color filters of the first-resolution image data and signals according to the plurality of color filters of the image data output from the conversion means. | 09-19-2013 |
