    • An image processing apparatus captures a target image containing marker images and a recognition target range identified by a marker-image set including at least parts of the marker images. The image processing apparatus includes an image capturing section, a first detection section, a position estimation section and a second detection section. The first detection section detects one marker image as a reference marker image from a captured image. The position estimation section adopts a marker image, which is other than the reference marker image and is contained in at least one of marker-image sets containing the reference marker image, as a corresponding marker image. The position estimation section estimates a position of the corresponding marker image in the captured image based on a size of the detected reference marker image. The second detection section detects the corresponding marker image based on the estimated position of the corresponding marker image.
    • 图像处理设备捕获包含标记图像的目标图像和由包括标记图像的至少一部分的标记图像组识别的识别目标范围。 图像处理装置包括图像拍摄部,第一检测部,位置估计部和第二检测部。 第一检测部分从捕获的图像检测一个标记图像作为参考标记图像。 位置估计部分采用除了参考标记图像之外的标记图像,并且包含在包含参考标记图像的至少一个标记图像集合中作为对应的标记图像。 位置估计部基于检测出的基准标记图像的大小来估计拍摄图像中的对应标记图像的位置。 第二检测部基于对应的标记图像的估计位置来检测对应的标记图像。
