    • Disclosed is a technology that specifies each of a plurality of two-dimensional codes in an image and reduces the processing time for judging color in each cell region in each specified two-dimensional code. Based on edge images generated from obtained images, candidate regions among these edge images are extracted, a judgment is made about whether or not a characteristic pattern is included in each of the corresponding regions in the original images that correspond to these extracted candidate regions, and then the two-dimensional code regions are detected from among the original images. The color is judged both for each pixel group that comprises each row of that region and for each pixel cell, in pixel array order. If it is determined that a certain number or more pixels in each row that corresponds to each cell region are included in the color judgment region, color judgment is omitted for the remaining pixels in that row.
    • 公开了一种指定图像中的多个二维码中的每一个的技术,并且减少了用于在每个指定的二维码中对每个小区区域中的颜色进行判断的处理时间。 基于从所获得的图像生成的边缘图像,提取这些边缘图像中的候选区域,判断在与这些提取的候选区域相对应的原始图像中的每个相应区域中是否包括特征图案,以及 然后从原始图像中检测二维码区域。 对于包括该区域的每行和每个像素单元的每个像素组,以像素阵列顺序判断颜色。 如果确定在颜色判断区域中包括与每个单元区域相对应的每行中的某一个或多个像素,则对于该行中的剩余像素,不再进行颜色判断。

    • Provided is an information processing system which includes: a communication device including a sensor that measures information regarding a posture thereof; and an information processing device. The information processing device displays a guide image for causing a user to perform a rotational operation for rotating the communication device, and executes calibration of the sensor by using the measurement result of the sensor acquired from the communication device while the guide image is displayed. The guide image includes an image representing a reference axis to be a rotation center for the rotational operation and an image representing the communication device, and the image representing the communication device is located within the guide image so that a portion of the communication device corresponding to a position of the sensor overlaps with the reference axis.
