    • A detecting unit detects any image area corresponding to a subject from the first image which is reduced resolution of an image that captured by an image capturing unit. With no image area detected as corresponding to the subject, a first control unit deems that an image area corresponding to the subject is absent in the image that captured by the image capturing unit. On the other hand, when the detecting unit detects an image area corresponding to the subject, a first determining unit determines whether or not the image area that detected by the detecting unit is an image area corresponding to the subject. If the area is determined to correspond to the subject, a second control unit deems that an image area corresponding to the subject is present in the image that captured by the image capturing unit.
    • 检测单元从第一图像检测与被摄体相对应的任何图像区域,该图像区域由图像捕获单元捕获的图像的分辨率降低。 在没有检测到与对象对应的图像区域的情况下,第一控制单元认为在由图像捕获单元捕获的图像中不存在与被摄体对应的图像区域。 另一方面,当检测单元检测到与被摄体对应的图像区域时,第一确定单元确定由检测单元检测到的图像区域是否是与被摄体对应的图像区域。 如果确定该区域对应于被摄体,则第二控制单元认为与被摄体对应的图像区域存在于由图像拍摄单元拍摄的图像中。
