TL;DR: In this article, the authors proposed a solution to the problem of finding a shape of a wall surface and a siding board by hand, which leads to a long-time work.
Abstract: PROBLEM TO BE SOLVED: To solve the following problem: as a shape of a wall surface and a shape of a siding board are prepared by hand, much efforts are involved, which leads to a long-time work. SOLUTION: When a camera 1 takes an image of the wall surface of a house, to which the siding board is attached, and an imaging signal is input to a personal computer 2, the imaging signal is converted into a display signal by an image conversion part 2a incorporated in the personal computer 2. As shown in Fig.2, the image A of the wall surface of the house is displayed on a display device 3 connected to the personal computer 2. In the image A of the wall surface of the house, a doorway B and a window C are displayed on the first floor, and a window D and small windows E, F, and balconies G, H are displayed on the second floor.

TL;DR: In this paper, the authors proposed a rotary processing method for color images, where a signal RGB sent from a sensor for each picture element is separated into a luminance signal Y and color difference signals I and Q by a color converting circuit after A/D conversion and stored in an image memory after the data compression processing.
Abstract: PURPOSE:To facilitate conversion processing together with reduction of the deterioration of signals and to edit images in a short time, by applying the image conversion processing to signals Y, I and Q respectively and then synthesizing again those signals to obtain the output image pictures. CONSTITUTION:A signal RGB sent from a sensor 11 for each picture element is separated into a luminance signal Y and color difference signals I and Q by a color converting circuit 13 after A/D conversion 12 and stored in an image memory 14 after the data compression processing. These stored signals are demodulated as signals Y, I and Q for each picture element and converted into the color signals by a color converting circuit 15 in response to an output device 16. While an image editing device 17 gives editing processing to the data of the memory 14 for variable power, etc. and sends the result of this processing again to the memory 14. The device 17 also displays the editing result through a monitor. The signals Y, I and Q undergo each processing and the signals I and Q are magnified by four times for synthesization. Thus the rotary processing is attained for color images.

TL;DR: In this paper, an interpolator (310) applies different weights to selected motion estimation value between target field and one of the initial and final fields having smaller difference value and motion estimation values to interpolate target field depending on whether one of initial or final fields has motion change greater than predetermined threshold.
Abstract: A detector receives three consecutive input fields. An interpolator (310) applies different weights to selected motion estimation value between target field and one of the initial and final fields having smaller difference value and motion estimation value between initial and final field to interpolate target field depending on whether one of initial and final fields has motion change greater than predetermined threshold. Independent claims are also included for the following: (1) interpolator; (2) image conversion method; and (3) computer readable medium storing image conversion program.

TL;DR: In this paper, the authors provide an image conversion method and image conversion device under different structures. But they do not provide a color deviation calculation effect, and the color deviation distinguishing better conforms to the characteristics of human body observation standards.
Abstract: The invention provides an image conversion method and an image conversion device under different structures. The method comprises the following steps of driving an OLED television to display a test picture group based on a picture output module; obtaining an actual test image group, taking pixel points as a unit, of the OLED television, on the basis of a camera module; based on a format conversionmodule, converting pictures of the test picture group and the actual test picture group from an RGB format into an HSV format; and based on a comparison module, performing comparison on the corresponding pictures in the test image group and the actual test image group. The image conversion device comprises the picture output module, the camera module, the format conversion module and the comparison module. The image conversion method and the image conversion device under different structures provided by the invention have a high color deviation calculation effect, and the color deviation distinguishing better conforms to the characteristics of human body observation standards and the like.

TL;DR: In this article, an anti-shake method and an antishake device for fundus shooting, a storage medium and electronic equipment, is presented, which comprises the steps of: acquiring image sequence data of fundus, and extracting feature points from the image sequences data; matching different frames of images of the fundus data based on the feature points, and determining an image conversion relationship according to a matching result.
Abstract: The invention provides an anti-shake method and an anti-shake device for fundus shooting, a storage medium and electronic equipment. The anti-shake method comprises the steps of: acquiring image sequence data of fundus, and extracting feature points from the image sequence data; matching different frames of images of the image sequence data based on the feature points, and determining an image conversion relationship according to a matching result; and determining corrected video data based on the image conversion relationship. According to the anti-shake method and the anti-shake device, image shaking caused by shooting shaking can be prevented, and the definition and stability of the fundus video or image data are improved, so that a doctor can analyze the condition of the fundus to be detected accurately and comprehensively.
