This invention relates to an autofocus preparation for improving autofocus by 8 degrees when inputting an image.

はならない。Automated cell diagnostic equipment and automatic blood cell sorting equipment are used to detect microscopic objects such as cells and blood cells (optically magnify them using a microscope).
In a device that converts the optical image into an electrical signal using a scanning device or the like and processes the image signal, focusing the eye U1 is an essential technique. In these automatic devices, the depth of focus becomes shallow because minute objects are optically magnified, and when the slide glass is moved to change the field of view, the optical axis of the optical system and the vertical part of the In addition, the distance of the object smeared on the surface of the slide glass in the optical axis direction changes with the movement of the field because the thickness of the slide glass is different from the original. Therefore, in order to obtain highly reliable image data, it is necessary to maintain a state of focus alignment and to prevent input of erroneous image data when the focus is misaligned.

めて少ない場合(二は自動焦点整合は不可能となる。By the way, the automatic focusing algorithm is based on the magnitude of the total density of the image data, the magnitude of the high-frequency component of the spatial frequency of the image data, and the magnitude of the sum of squares of the difference values between adjacent picture elements. All rJ is established on the assumption that an image exists within the field of view. However, when smearing cells, blood cells, etc. on a glass slide (2), it is difficult to smear the whole C uniformly (2), and there may be cases where there are few cells, blood cells, etc. depending on the field of view. Field of view (=If there are no or very few cells or blood cells, etc., automatic focusing is impossible.

法が採られていた。For this reason, in order to compensate for the above-mentioned drawbacks (as shown in Fig. 1), the surface of the object to be measured with the slide in the vicinity of the plane to be focused (2) is smeared on the surface of the object to be measured (2) where the slide is in the vicinity of the surface to be focused (2).
A method has been adopted in which more regular minute marks 4 are applied and focus alignment is performed using the marks 4 even in a small field of view of the object to be measured.

も特殊な設備を要するという欠点かあった。However, cells and blood cells are thick and the marked opening 11 is not necessarily the focus position #5', so when the magnification is high, the depth of focus is shallow as described above, so it is not possible to correctly identify MII cells or IO'1 bulb, etc. (- does not mean that it is in focus. Also, since the marks are extremely thin, (2, on top of that) it is inevitable that cells, blood cells, etc. overlap, so when inputting images, do not include the C2 mark. may be processed,
There was a risk of inputting incorrect image data. Furthermore, double-sided markings made by metallization are expensive and require special equipment.

According to 2, during the process of smearing the cells and blood cells (=, a microscopic object called a focus alignment marker is mixed into the cells and blood cells in advance, and the focus alignment marker is smeared on the slide glass C''' at the same time as the cells and blood cells.

.j、liすものならどのようなものでも良い。Here, we will discuss two markers for focus alignment used in the present invention. The function of this marker is to increase the absorption of light with the background, improve the detection accuracy of focus alignment, and connect the marker and cells after inputting image data. It is characterized by correctly identifying objects to be measured such as cells and blood cells, preventing overlap between cells and blood cells and markers, and preventing the slide from adhering to other objects during lath smearing (= uniform smearing). Therefore, the following focus alignment markers are used.

By mixing with the object to be measured, cells, blood cells, etc., which are the object to be measured) Automatic focusing is possible even in fields where there is no or a small field of view (2 or 2 markers for focus alignment).
Since the thickness is almost the same as that of IJ cells and blood cells, the focusing shield is more accurate (1
