- the print candidate area extracting step performed in step 1-2 is a process of extracting, as the print candidate area B, an area including the print attached to the packaging bag from the front side illumination image.

- a process (cutout process) for cutting out the print / drug assumed area to be performed is performed. That is, the print and the shadow of the medicine appear as black or dark in the backlit gray image, and the background appears as white or light. Therefore, by performing dynamic binarization processing on the back-lighted gray image, it is possible to cut out the area where the printing and the medicine exist (black area) from the background area (white area).
- step 2-3 the control flow proceeds to step 2-3, and the assumed print area derivation process is performed.
- the back-lighted gray image is top-hat processed to derive an area brighter than the surroundings (top hat area). Further, by performing a bottom hat process on the back-lighted gray image, an area darker than the periphery (bottom hat area) is derived. In this way, the top hat area and the bottom hat area correspond to areas where printing is expected (print expected area). Therefore, the control device 60 derives the sum area of the top hat area and the bottom hat area as an assumed print area where the presence of printing is assumed.

Therefore, in step 3-1, first, bottom hat processing (channel image bottom hat processing) is performed on each of the R channel image, the G channel image, and the B channel image.

- the assumed print area is an area corresponding to characters attached to the packaging bag b. Therefore, by deriving the luminance in this region, it is possible to define a luminance standard for distinguishing between the region corresponding to the character and other regions, specifically, the markings attached to the medicine.
- the process of deriving the assumed print area in step 4-1 is not executed, and the assumed print area derived in the drug candidate area extracting step in step 1-2 is used. It is also possible to derive the expected print area in 1 again.
- the process proceeds to the print area narrowing process in step 4-2.
- the print area narrowing process the print candidate area B derived by the print candidate area extraction process performed in step 1-2 described above is used.
- Step 4-2 the image in the print area C (see FIG. 6F) included in the print candidate area B in the front side illumination image is based on the luminance standard defined in Step 4-1.

Abstract
Description
制御装置60は、薬剤の画像をマスター画像として蓄積した画像データベース62を備えている。制御装置60は、画像データベース62に登録されているマスター画像と、撮影装置40によって取得された薬剤の画像とをマッチングする画像マッチング処理を実行することにより、薬剤の数量及び種類のいずれか一方又は双方を薬剤情報として検出する薬品情報検出制御を実行可能である。以下、制御装置60によって実施される薬剤情報検出制御について先ず概略を説明した後、各工程において実施される制御について順を追って具体的に説明する。
薬品情報検出制御は、正面側照明装置52をオン状態として撮影装置40により撮影された正面側照明画像と、背面側照明装置54をオン状態として撮影装置40により撮影された背面側照明画像とを用いて実施される。正面側照明画像は、図6(a)に示すように分包袋bを正面視した状態の画像であり、薬剤及び分包袋bに付されている印字とが写った画像となる。また、背面側照明画像は、図6(b)に示すように薬剤の影と分包袋bに付されている印字とが写った画像となる。制御装置60は、正面側照明画像及び背面側照明画像に基づき、分包袋b内に収容されている薬剤の画像を抽出し、この薬剤の画像に基づいて薬剤情報を検出する。
続いて、薬剤を画像鑑査する際に用いられる画像データベース62に登録されているマスター画像として、複数に分割した分割薬剤に関するものを作成する方法について説明する。制御装置60は、マスター画像作成手段64を備えている。マスター画像作成手段64は、画像データベース62に登録される薬剤の全体形状を示すマスター画像に基づき、この薬剤を複数に分割した分割薬剤についてのマスター画像を作成することができる。以下、マスター画像作成手段64による分割薬剤に係るマスター画像の作成方法について、図11に示したフローチャートを参照しつつ順を追って説明する。
続いて、撮影装置によって撮影した画像に基づいて作成されたマスター画像を、既登録のマスター画像と置換するマスター画像差し換え処理について説明する。マスター画像差し替え処理は、撮影装置40や照明装置50の個体差等に起因し、同一の薬剤について撮影を行っても色調等が異なる可能性を考慮し、薬剤の鑑査精度を向上させるために実施される処理である。すなわち、マスター画像差し替え処理は、画像データベース62に登録されているマスター画像と、実際に撮影装置によって撮影して得られる画像とで色調が相違する等して薬剤の特定がうまくいかないことを抑制するために実施されるものである。
