Description

前記課題を解決するために請求項１記載の発明は、時間的に連続する複数の画像を取得する画像取得手段と、この画像取得手段によって取得された複数の画像から、合成の基準となる基準画像を選択する選択手段と、前記画像取得手段によって取得された複数の画像を画素加算合成して一つの画像を生成する画像生成手段と、前記選択手段によって選択された基準画像と前記画像取得手段によって取得された他の画像との画素毎の差分の最大値を、前記他の画像毎に取得する差分取得手段と、この差分取得手段によって取得された情報を透過強度の情報として前記画像生成手段により生成される画像にブレンディングするブレンディング手段とを備えたことを特徴とする。 In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that an image acquisition unit that acquires a plurality of temporally continuous images and a reference that is a reference for synthesis from the plurality of images acquired by the image acquisition unit. A selection unit for selecting an image; an image generation unit for generating a single image by adding and synthesizing a plurality of images acquired by the image acquisition unit; a reference image selected by the selection unit; and the image acquisition unit A difference acquisition unit that acquires, for each of the other images, the maximum value of the difference for each pixel from the other image acquired by the image generation unit, and the image generation unit that uses the information acquired by the difference acquisition unit as transmission intensity information. And blending means for blending the image generated by the above.

また、請求項６記載の発明は、時間的に連続する複数の画像を取得する画像取得ステップと、この画像取得ステップによって取得された複数の画像から、合成の基準となる基準画像を選択する選択ステップと、前記画像取得ステップによって取得された複数の画像を画素加算合成して一つの画像を生成する画像生成ステップと、前記選択ステップによって選択された基準画像と前記画像取得ステップによって取得された他の画像との画素毎の差分の最大値を、前記他の画像毎に取得する差分取得ステップと、この差分取得ステップによって取得された情報を透過強度の情報として前記画像生成ステップにより生成される画像にブレンディングするブレンディングステップとを含むことを特徴とする。 The invention according to claim 6 is an image acquisition step for acquiring a plurality of temporally continuous images, and a selection for selecting a reference image as a reference for synthesis from the plurality of images acquired by the image acquisition step. An image generation step for generating a single image by adding and synthesizing a plurality of images acquired by the image acquisition step, a reference image selected by the selection step, and another acquired by the image acquisition step A difference acquisition step of acquiring the maximum value of the difference for each pixel from the image of each other image, and an image generated by the image generation step using the information acquired by the difference acquisition step as transmission intensity information And a blending step for blending.

また、請求項７記載の発明は、装置が有するコンピュータを、時間的に連続する複数の画像を取得する画像取得手段、この画像取得手段によって取得された複数の画像から、合成の基準となる基準画像を選択する選択手段、前記画像取得手段によって取得された複数の画像を画素加算合成して一つの画像を生成する画像生成手段、前記選択手段によって選択された基準画像と前記画像取得手段によって取得された他の画像との画素毎の差分の最大値を、前記他の画像毎に取得する差分取得手段、この差分取得手段によって取得された情報を透過強度の情報として前記画像生成手段により生成される画像にブレンディングするブレンディング手段として機能させることを特徴とする。 According to a seventh aspect of the present invention, there is provided an image acquisition means for acquiring a plurality of temporally continuous images from a computer included in the apparatus, and a reference that is a reference for synthesis from the plurality of images acquired by the image acquisition means Selection means for selecting an image, image generation means for generating a single image by adding and synthesizing a plurality of images acquired by the image acquisition means, a reference image selected by the selection means, and acquisition by the image acquisition means A difference acquisition unit that acquires the maximum value of the difference for each pixel from the other image thus obtained for each of the other images, and the information generated by the difference acquisition unit is generated by the image generation unit as transmission intensity information. It is characterized by functioning as a blending means for blending into an image .

引き続き、下記式［１０］で示すように、強調処理を行って前記動体判定マップＭのコントラストをアップさせる（ステップＳ２０５）。
Map_Move = fEmphasis (Ave_Diff_Lpf) ・・・式［１０］
このステップＳ２０５での平滑化処理により、図５（ｂ）に示すように、動体判定マップＭにおいて動体の手Ｈの像が重なる領域のコントラストがアップされる。 Subsequently, as shown by the following equation [10], enhancement processing is performed to increase the contrast of the moving object determination map M (step S 205 ).
Map_Move = fEmphasis (Ave_Diff_Lpf) Expression [10]
By the smoothing process in step S205, as shown in FIG. 5B, the contrast of the area where the image of the moving hand H overlaps in the moving object determination map M is increased.
