20090067015 | BLOCK MATCHING CIRCUIT AND DATA UPDATE METHOD - Scanning image data and target image data are respectively stored in a first storage area and a second storage area. In one case, (J−M+1)×(K−N+1)×M×N pieces of pixel data are stored as comparison image data relating to all comparison areas, and M×N pieces of pixel data are stored as target image data. In contrast, the present invention requires the storage only of J×K pieces of pixel data as scanning image data, and M×N pieces of pixel data as target image data. This means the number of pieces of pixel data to be stored is reduced. In the case discussed above, one piece of target image data and (J−M+ | 03-12-2009 |
20090245683 | DEFECTIVE PIXEL CORRECTION DEVICE - First pixel data of a pixel of interest is output from a first shift register, while second and third pixel data of neighboring pixels indicative of the same color are output from second and third shift registers, respectively. Differential data between estimated pixel data calculated from the second and third pixel data and the first pixel data is input to a comparator. A threshold value stored in a register is modulated by the estimated pixel data, and is input to the comparator as modulated threshold data. When the comparator judges that the differential data is greater than the modulated threshold data, a selector outputs the estimated pixel data as corrected pixel data. | 10-01-2009 |
20110122298 | IMAGE PROCESSING APPARATUS, AND METHOD OF OPERATING AN IMAGE PROCESSING APPARATUS - An image processing apparatus includes: a relative coordinate acquisition part acquiring a corresponding position on an input image with respect to a predetermined pixel on an output image; a first storage part storing position information of the corresponding position; a reading control part causing pixel values of input pixels on the input image to be sequentially read; an organization part organizing a set of grid points formed of input pixels among input pixels read by the reading control part; a judgment part judging, based on the position information, whether or not pixel values of pixels in the vicinity of the corresponding position used in calculating a pixel value of the predetermined pixel have been read; a local memory storing, in a case where judgment is made that pixels in the vicinity of the corresponding position have been read, pixel values of pixels forming the set of grid points as pixel values of surrounding pixels regarding the predetermined pixel; and a pixel value calculation part calculating a pixel value of the predetermined pixel by interpolation using the pixel values of the surrounding pixels. | 05-26-2011 |
20110194765 | IMAGE PROCESSING APPARATUS - An image processing apparatus is provided which offers higher versatility than conventional image processing apparatuses. When an input signal to a spatial filtering block is a monochrome signal that contains Y component only, a selector selects its input terminal and a selector selects its input terminal. Then, a low-pass filter output signal of a programmable spatial filter is inputted to a spatial filter, and a low-pass filter output signal of the spatial filer is inputted to a spatial filter. That is, the programmable spatial filter and the spatial filters are connected in series (in cascade), and the cascade-connected three spatial filters perform filtering operation. In this example, low-pass filters with 5×5 taps are connected in cascade in three stages, which enables low-pass filtering with 13×13 taps. | 08-11-2011 |
20120002080 | IMAGE PROCESSING APPARATUS HAVING A BUFFER MEMORY FOR IMAGE DATA STORAGE - Two local buffers are provided between an image processing unit and an image compression and expansion unit for compression into a predetermined format. Write and read control units serve to alternately use the two local buffers. As a result, process flow starting from the image processing unit to generate compressed image data by the image compression and expansion unit requires no main memory, whereby high-speed image processing is allowed with low power consumption. | 01-05-2012 |
20120081372 | IMAGE PROCESSOR - An image processing unit includes a computing unit, a data input unit that inputs image data to the computing unit, a data output unit that outputs the image data computed by the computing unit, and a setting unit. The computing unit includes computing cells including multiple types of computing cells, input domain selectors, and at least one of output domain selectors. The setting unit sets the input domain selectors and the output domain selectors so that image data inputted by the data input unit to the computing unit on which desired computing has been performed by at least one computing cell among the computing cells is outputted from the data output unit. | 04-05-2012 |
20120093410 | IMAGE PROCESSING APPARATUS AND METHOD FOR OPERATING IMAGE PROCESSING APPARATUS - An image processing apparatus includes a first storage section and a second storage section, a storage control section, and a computation section. The storage control section sequentially acquires block images obtained as a result of dividing an input image, and stores the block image as a target block image in the first storage section, while storing, in the second storage section, image data of, in a region of the target block image, a region abutting un-inputted block images in the input image, as image data of an abuttal region. The computation section implements a resizing process for changing the size of the target block image by performing an interpolation calculation using image data of the target block image stored in the first storage section and the image data of the abuttal region stored in the second storage section. | 04-19-2012 |
