[0052] refer to figure 1 A first embodiment of the present invention will be described. The microscope imaging system 101 includes an imaging device 102 and an image processing device 103 .

[0053] The imaging device 102 includes an objective lens 111 , a specimen holding unit 112 , a three-axis stage 113 , an image sensor 114 , an imaging processing board 115 , a specimen selection unit 116 , a halogen lamp 117 and a motorized filter wheel 118 . Six kinds of color filters can be mounted on the motorized filter wheel 118 . In normal imaging, three color filters RGB are used.

[0054] The image processing apparatus 103 is configured by installing a necessary image processing program in a commercially available workstation. This workstation is also used as the control device 104 for the overall system operation. The imaging device 102 and the image processing device 103 (control device 104 ) are connected by a network cable 105 and can transfer data bidirectionally. The im...

[0154] A second embodiment of the present invention will be described. The second embodiment is a microscope that acquires multi-layer tiles (hereinafter referred to as z-stack data (stack data)) for each state number (each imaging area) and stitches tiles for each layer so as to acquire the three-dimensional structure of the entire specimen imaging system. The microscope imaging system in the second embodiment includes a configuration similar to that of the microscope imaging system in the first embodiment. However, the microscope imaging system in the second embodiment is different from the microscope imaging system in the first embodiment in that the workstation is not used as the image processing device and the image processing device is mounted on the image processing board, and in that the image processing device The peripheral data is losslessly compressed and transmitted to the image processing device.

[0155] Such as Figure 16 As shown in , the microscope imaging...

[0182] A third embodiment will be described. A third embodiment is an imaging apparatus characterized by having a function of transmitting tiles subjected to lossy compression and peripheral data subjected to lossy compression after performing divisional imaging. The configuration of the imaging device in the third embodiment is basically the same as that of the imaging device in the first embodiment. However, the imaging device in the third embodiment differs from that in the first embodiment in that lossy compression processing is performed in the image processing board after peripheral data clipping.

[0183] Due to device configuration with figure 1 The configuration of the imaging device 102 shown in is the same, so the description of the device configuration is omitted. The configuration of the imaging processing board and figure 2 Same configuration as shown in . However, the data exchange performed by the data clipping / compression processing controller 147 is diff...

Abstract

A imaging apparatus images a plurality of areas of an object such that end portions of adjacent areas overlap each other and generates, for each of the plurality of areas, image data of the area and peripheral data, which is data of an overlapping portion of the area and an area adjacent to the area and lossily compresses the image data. A image processing apparatus acquires the lossily compressed image data and the peripheral data of each of the plurality of areas and determines, using peripheral data of adjacent two areas, a parameter used for stitching image data of the two areas and decodes the lossily compressed image data and stitches the decoded image data of the plurality of areas using the parameter.

Description

technical field [0001] The present invention relates to a microscope imaging system with the function of stitching images together. Background technique [0002] In recent years, in order to solve problems such as shortage of pathologists and telemedicine, the importance of diagnosis using images of pathological specimens has increased. The pathological specimen image is acquired by a microscope including a motorized stage or a medical slide scanner (hereinafter referred to as a microscope imaging system). However, in order to obtain high-accuracy images suitable for diagnosis, a large number of technical problems need to be overcome. [0003] As one of the technical problems, a problem related to image stitching is known. The extent of the specimen that can be imaged by the objective lens of a digital microscope is small compared to the entire specimen, usually equal to or less than one percent of the entire specimen. Therefore, in order to image the entire specimen, mul...
