Multispectral image processing device and color reproduction system using the same

Abstract: A multispectral image processing device of the present invention comprising: a base image conversion unit 6 , which expands an input multiband image of a subject based on a base vector to convert it into a base image; a base vector calculation unit 2 , which calculates the base vector; and an output unit 7 , which outputs a multispectral image based on the base image converted in the base image conversion unit 6 is characterized in that the base vector calculation unit 2 calculates a base vector for 3 primary colors obtained by the product of a predetermined rendering illumination spectrum and a color matching function, and an orthogonal base vector, which is orthogonal to the base vector for 3 primary colors and based on statistical information on the spectral reflectance of the subject as the base vectors. Thereby, a multispectral image is converted into image data highly compatible with an existing 3-band system.

Image acquisition method based on domestic CPU and domestic OS

Abstract: The invention discloses an image acquisition method based on a domestic CPU and a domestic OS. The specific realization process of the method is as follows: a domestic CPU and a domestic OS (Operating System) are internally installed in image acquisition equipment, wherein the image acquisition equipment adopts the structure in whole sequentially including a system interface layer, an equipment driver layer, an equipment member layer, an equipment factory layer and a plug-in interface layer; the plug-in interface layer is called by a foreground page JS and equipment parameters are transmitted in; the call request of the foreground page is received by the plug-in interface layer, and a corresponding equipment member example is generated by the equipment factory layer as per the equipment parameters; an image acquisition interface and an image format conversion interface of the corresponding equipment example are called by an image acquisition plug-in, so that image data and an image conversion format are collected; a drive program of the corresponding equipment in the equipment driver layer is called by an image acquisition interface, so that image data is collected. Compared with the prior art, the image acquisition method based on the domestic CPU and the domestic OS, provided by the invention has the advantage that the image acquisition equipment adopting the method is good in universality and expansibility and high in practicability.

Color Image Edge Detection Combining with Gauss Manhattan Distance Map in RGB Space

Abstract: In order to make better use of information for edge detection of color image,an approach of color image edge detection which combines Gauss Manhattan distance map into RGB space is proposed in this paper.Firstly,the loss of information generated from color image to gray image conversion is analysised and a method of RGB space edge measurement is raised.Then,a new unified distance map is got fromseparately Gauss Manhattan distance map of color image by the measurement in three channels of RGB.Finally,a new unified distance map is mapped to range of 0~ 255,and the result of edge detection is obtained.Experimental results show the approach proposed in this paper has higher processing speed and better treatment effect.

Medical image display method and display device

Abstract: The invention discloses a medical image display method and a display device. The method comprises steps: after a user triggers an image display request, a first medical image which is requested currently and a second medical image which is corresponding to the first medical image are displayed in an image display window to enable the first medical image and the second medical image not to be displayed in an overlapped mode. Thus, through only displaying the first medical image on a small screen and avoiding mutual overlapping between the images, a clear image display effect can be achieved; later, the user can operate the first medical image according to browsing requirements, during a first medical image conversion process, the display position and/or the display size of the second medical image can be adjusted adaptively, and thus, while the user can clearly browse the first medical image at a mobile end, the related information of the first medical image can be queried through the second medical image, and the user can find out the lesion through the displayed images.

An image display system comprising a plurality of image output devices

Abstract: The utility model provides an image display system comprising a plurality of image output devices. To be specific, the system comprises a front image processing device, a signal conversion device, a signal distributor and a plurality of image output devices, wherein the front image processing device is used for compressing a plurality of image signals into an image compression unit, and the image conversion device and the signal distributor receive the image compression unit and copy and output a plurality of image compression digital signals having the same content. When each image output device respectively receives corresponding signals of the image compression digital signals, each image output device can amplify and output some image frames signals of the received image compression digital signals. The image display system can effectively reduce erection cost of the image display system and can increase erection elasticity of the image display system.
