## Background
CROSS REFERENCE TO RELATED APPLICATION
This application is based upon and claims the benefit of priority from the prior Japanese Application No. 2007-169684 filed Jun. 27, 2007, the entire contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an image information display processing apparatus for executing a display process for a plurality of pieces of image information obtained by being captured with the elapse of time, for example, with a capsule endoscope that autonomously or heteronomously moves within a body to be examined.
2. Description of the Related Art
In recent years, a so-called swallow-type capsule endoscope has been made its debut in an endoscope field as disclosed, for example, by US Patent Application Publication No. 2002/0177779A1.
The capsule endoscope has an image capturing function and a wireless communication function. The capsule endoscope sequentially captures the images of organs such as the stomach, the small intestine, etc., and wirelessly transmits information about the sequentially captured images (electronic data representing images) during an observation period from when it is swallowed from the mouth of a patient in order to observe or examine the organs until when it is naturally excreted from the body.
The wirelessly transmitted image information in this way is received by a receiver that is provided outside the body of the patient, stored in a predetermined memory, and read and displayed on a display unit as occasion demands, whereby the image information becomes available for a diagnosis, etc. made by a doctor as disclosed, for example, by Japanese Published Unexamined Patent Application No. 2005-218584.
However, for such a capsule endoscope, the period from when it is swallowed from the mouth of a patient until when it is naturally excreted is an observation period or an examination period unlike a normal endoscope.
Case data shot with the capsule endoscope during this period is composed of approximately 60,000 images as materials shot for the maximum of approximately eight hours, and the number of pieces of image information (case data) is vast.
In addition, information about images shot with the capsule endoscope in the past include image information of many patients, and also information about images shot on different examination dates even for the same patient, and are stored in a database.
SUMMARY OF THE INVENTION
A display processing apparatus according to the present invention is a display processing apparatus for storing an image within a body to be examined, which is shot with an image capturing device introduced into the body to be examined, and for displaying the image on a display screen, and comprises a display unit having a case data display region for displaying on the display screen one or more pieces of case data including at least one of the ID of a patient, the name of the patient, and an examination date, and a case data associated information display region for displaying information associated with each piece of the case data, and a case data associated information display switching unit for switching the information associated with each piece of the case data displayed in the case data associated information display region.

On the display screen 26 of the monitor device 21 of the workstation 7 shown in FIG. 1, a case data listing display window 27 is displayed with an initial operation procedure as shown in FIG. 2.
In the case data listing display window 27, case data numbers are displayed in an ascending order starting at 001 to 002, 003, . . . , in a case data number field 28 in the left portion. Additionally, identification data corresponding to each case data number in the left portion is displayed in an identification data field 29 in the right portion.
For example, at least the name and the ID of a patient, an examination date, etc. are displayed as the identification data displayed in the identification data field 29 although these are not shown in FIG. 2.
In FIG. 2, only five data rows are displayed in the case data number field 28 and the identification data field 29. However, all of data rows stored in the database 9 can be displayed with scrolling.
If the doctor or the nurse desires to obtain the case data of a desired examination date of a desired patient while he or she is viewing the identification data displayed in the identification data field 29, he or she selects the corresponding case data number, and performs an input operation, for example, double-clicks on the corresponding number with a pointing device such as the mouse, etc., so that an observation image screen is displayed.
FIG. 3 is a schematic diagram showing an example of an observation image display screen displayed on the display screen of the monitor device of the workstation in the first preferred embodiment.
As shown in this figure, the currently selected observation image 31 is displayed in an upper middle portion of the observation image screen 30 displayed on the display screen 26. Four types of time data 32 associated with captured images are displayed in an upper portion at the left of the observation image 31, and image captured positions (positions within the body) data 32 is two-dimensionally displayed below the time data 32.
Additionally, a plurality (five in this figure) of instruction buttons 34 are displayed in an upper left portion of the display screen 26. Moreover, a replay button group 35 including replay buttons that are positioned on the right side of a stop button as a center and intended to respectively instruct a replay, a fast-forward replay and a frame-by-frame forward replay, and replay buttons that are positioned on the left side of the stop button and intended to respectively instruct a backward replay, a fast-backward replay and a frame-by-frame backward replay is displayed below the middle of the display screen 26.
Furthermore, a red color detection bar 37 and a time bar 38 are displayed above and below an average color bar 36 in a portion below the replay button group 35 on the display screen 26.
The average color bar 36 represents average colors of captured images in positions on the time axis while the capsule endoscope 3 is moving within the organs.
A display controlling unit controls the representation of average colors to be displayed as one horizontal average color bar 36 implemented by arranging vertical lines each of which is represented with an average color calculated for each captured image (video image) or for every plural images along the time axis of the time bar 38, namely, in time series in the horizontal direction of the display screen 26 in order to obtain image capturing positions by using a characteristic such that colors differ depending on the organs.
Horizontal lines each represented with an average color may be arranged in the vertical direction or an oblique direction in time series. Namely, the direction of the average color bar does not matter.
In the meantime, the display controlling unit controls the display of the red color detection bar 37 so that a position (red color detection position) at which bleeding is found on the time axis is represented as a red color line within the horizontal bar on the display screen 26.
The red color detection bar 37 is one type of lesion color bars. The red color detection bar 37 may be represented as a vertical or an oblique bar on the display screen. The direction of the red color detection bar does not matter.
A lesion is not limited to bleeding. There are other lesions that can be clearly identified with an image shot by the capsule endoscope 3. These lesions can be displayed with lesion color bars in blue, white or other colors other than the red color depending on lesions.
The present invention is described by using the red color detection bar as an example of a lesion color bar. Moreover, in FIG. 3, the time bar 38 is a bar that indicates the elapse of time during which the capsule endoscope 3 moves within the body of the person to be examined 4, and comprises a slide button.
By moving the slide button along the time bar 38 with a pointing device such as the mouse, etc., a captured image on the time axis specified with the slide button is displayed as the currently selected observation image 31.
Additionally, horizontally scrollable thumbnails 39 are displayed at the bottom of the display screen 26.
Unless otherwise specified, the currently selected observation image 31 among the thumbnails 39 is displayed at the center, and the thumbnails 39 of the captured images consecutive to the currently selected observation image 31 in time series are displayed at the right and the left of the currently selected observation image 31.
Alternatively, thumbnails of captured images that are sampled at predetermined time intervals or every predetermined number of thumbnails can be displayed.
Additionally, the doctor presses any of the instruction buttons 34 on the observation image screen 30 shown in FIG. 3, whereby, for example, a listing display of red color detection bars 37 for the respective pieces of case data shown in FIG. 2 can be made.
