Abstract

PURPOSE:To shorten a retrieving time by providing the retrieving system with a film digitizer for electrifying a medical roll film, a storage device for storing a digitized image, an operating console for reading out the stored image, and a control device for extracting only a necessary image. CONSTITUTION:The medical roll film is electrified by the film digitizer 1 and stored as image data without recognizing a boundary between respective images photographed in the roll film, and at that time an operator inputs the number of images in the roll film. The control part 3 calculates the order of the image and the stored position of the image based upon the storage position information of the image data and the information indicating the number of images inputted from the console 2 by the operator. Consequently, the image corresponding to the retrieving request of a certain image can be immediately read out from the console 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image retrieval method, and particularly to an image retrieval method in an electronic filing system for medical roll film.

[Conventional technology]

The image retrieval system in the conventional medical roll film electronic filing system cannot automatically recognize the boundaries between images taken on the roll film, so images are retrieved in order when searching for stored images. Alternatively, they only dealt with rolls of film that had the boundaries between images marked by a particular camera.

[Problem to be solved by the invention]

In the conventional image retrieval system described above, when an operator retrieves a certain image from a storage device, it is necessary to read out the images in order from the beginning, and the retrieval takes a long time. Furthermore, when only roll films photographed by a specific photographic device are targeted, the photographing device must be modified and cannot be easily introduced.

[Means to solve the problem]

The image retrieval system of the present invention includes a film digitizer for digitizing medical roll film, a storage device for storing images digitized by the film digitizer, and an operator for reading out the stored images. and a control device that extracts only the necessary images in a predetermined procedure from among a plurality of computerized roll film images.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

First, an outline of the present invention will be described.

Medical roll film stores image data digitized by a film digitizer without recognizing the boundaries between images shot on the roll film. At this time, the operator inputs the number of images contained in the roll film.

The control unit calculates how many images are stored in which storage location based on the information about the storage location of the image data and the information about the number of images input by the operator from the operation console. , it is possible to have a function to immediately read out a corresponding image from an operation console in response to a search request for a certain image.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

1 is a roll film digitizer, which is a device for digitizing medical roll film. The roll film image data digitized by the roll film digitizer 1 is stored in the storage device 4 via the control device 3. At this time, the operator inputs the number of images taken on the electronic roll film using the keyboard of the operation console 2.

FIG. 2 is an explanatory diagram of a storage format of data stored in a storage device. The shaded area in Figure 2 shows the data storage area for one roll of electronic roll film, and one roll of roll film is stored as one data without considering the boundaries of each image within the roll film. . Point A in the second section indicates the storage start position, and point B indicates the storage end position. When an operator searches for the n-th image when X images are stored in the roll film, it is possible to calculate the storage position N of the n-th image using the following equation.

N=A+ (B-A)(n/X) The control device 3 in FIG. 1 calculates the storage position N, reads the corresponding image data from the storage device 4, and
It is displayed on the CRT display of the operation console 2.

〔Effect of the invention〕

As explained above, the present invention allows a necessary image to be quickly retrieved from the information on the storage position of the roll film, so there is no need to detect boundaries between images, and it is not necessary to modify the photographing device for boundary detection. This has the effect of making it unnecessary. Another advantage is that it is possible to construct an image search method in a medical roll film electronic filing system that can also input existing photographed roll films.

FIG. 3 is an explanatory diagram of a storage format of room data.
