Imaging method applied to endoscope system

Abstract: The invention discloses an imaging method applied to an endoscope system. The imaging method comprises the following steps: radiating an observed part by using radiation light of a preset wave band, and acquiring a reflection light image of the observed part; and multiplying tone matrixes of different pixels of the reflection light image with an image conversion matrix respectively so as to obtain an imaging result of the observed part, wherein the image conversion matrix is calculated according to a weight coefficient diagonal matrix, and the diagonal elements of the weight coefficient diagonal matrix are weight coefficients of the acquired reflection light image under light intensity of different narrow-band wave bands, and the preset wave band is divided into a preset number of narrow-band wave bands averagely. According to the imaging method applied to the endoscope system, the observed part is radiated with light of the preset wave band, the reflection light image in which a blood vessel zone and a non-blood vessel zone can be distinguished can be obtained, and characteristic spectrums of different zone images can be intensified after the image is subjected to spectrum filtering processing, so that differences of the blood vessel zone and the non-blood vessel zone can be improved, the image contrast degree can be increased, and the imaging quality can be improved.

Topographic map creation device and topographic map creation method

Abstract: PROBLEM TO BE SOLVED: To provide a topographic map creation device and a topographic map creation method for creating a topographic map with detailed land features to be easily read. SOLUTION: When a hue determination part 10, a luminance determination part 12 and an irregularity correction part 14 acquire altitude data from a numerical altitude model 24, the hue determination part 10 generates hued altitude data, the luminance determination part 12 generates sunlight reflection intensity data and the irregularity correction part 14 generates correction data of detailed irregularity information based on the altitude data. In addition, a saturation determination part 16 determines saturation data based on a processing result of the irregularity correction part 14. An image synthesizing part 18 uses the hued altitude data, the sunlight reflection intensity data and the saturation data to synthesize target image data on the ground surface as image data of an HSI color space and an image conversion part 20 converts the image data into an RGB color space to be displayed on an image display part 22.

Video signal processing method, integrated circuit, and video reproducer

Abstract: For example, in reproduction of a BD-ROM, when two streams of image data having different resolutions are displayed in a picture-in-picture mode, the difference in a sense of resolution between two windows is reduced. In an image conversion section, first image data is converted to image data in a progressive scan format by i-p conversion section, and then, the image size of the first image data is converted so that the first image data is output as third image data. The synthesizing section synthesizes the third image data with second image data, and outputs the synthesized data.

Information processor, method for controlling information processor, and program

Abstract: PROBLEM TO BE SOLVED: To remove a SPAM text or SPAM mail that has not been eliminated by a conventional character-based filtering, such as a text written not in horizontal format or a text including a character string containing symbols. SOLUTION: An image conversion part 302 generates a text image by converting a text received by a text reception part 301 into an image. An image comparison part 309 and a similarity calculation part 310 compare the text image with a plurality of specimen images stored in a specimen image storage part 106, and calculates similarity between the text image and the specimen images. When the similarity is higher than a threshold, a text deletion instruction part 312 does not permit the use of the received text that has been a basis for the text image. When the similarity is not higher than the threshold, a text registration instruction part 311 permits the use of the received text. COPYRIGHT: (C)2011,JPO&INPIT

Image display device, image processor, image display device control program, and image processor control program

Abstract: PROBLEM TO BE SOLVED: To provide an image display device capable of accurate divisible scanning, an image processor, an image display device control program, and an image processor control program by converting the size of an image displayed in a display area, consisting of scanning lines, such that the addition number obtained by adding one to the number of scanning lines can accurately be divided into a numeral group corresponding to the ratio of a 2 n value, into a size which can accurately be divided according to the number of scanning lines. SOLUTION: The image display device 10 includes a panel 10a, a control part 10b, a driving part 10c, a frame memory 10d, an image analysis part 103, and an image conversion part 10f. And, the image analysis part 10e analyzes an input image from outside and the image conversion part 10f converts the size of the input image according to the number of scanning lines of a display area of the panel 10a according to the analysis result to perform accurate nonsequential scanning processing.
