    • Disclosed herein is a data reader including: an image acquisition section configured to acquire an image having color cells arranged in a two-dimensional space, each of the color cells being made up of a graphic of a given color density in a predetermined form and size; a spatial deinterleaving section configured to perform spatial deinterleaving adapted to sort the color cells arranged in the two-dimensional space in a spatially distributed manner in the acquired image; and a color decoding section configured to decode data coded in association with colors of the color cells and densities of the colors by analyzing the image with the sorted color cells as color data associated with coordinate positions in the two-dimensional space.
    • 本文公开了一种数据读取器,包括:图像获取部,被配置为获取具有以二维空间排列的彩色单元的图像,每个颜色单元由预定形式和尺寸的给定颜色浓度的图形组成 ; 空间解交织部分,被配置为执行空间解交织,其适于在所获取的图像中以空间分布的方式对布置在二维空间中的颜色单元进行排序; 以及颜色解码部分,被配置为通过分析具有排序的颜色单元的图像作为与二维空间中的坐标位置相关联的颜色数据来解码与颜色单元的颜色和颜色密度相关联地编码的数据。

    • Disclosed herein is a signal processing apparatus including a plurality of frame head detection sections configured to determine whether a frame head complying with any one of a plurality of different communication methods is detected by comparing the waveform of a signal sent from an external apparatus with a plurality of predetermined different symbol patterns; a communication method selection section configured to select the communication method for communicating with the external apparatus based on results of the determination by the frame head detection sections and on the priority of each of the plurality of communication methods; and a priority changing section configured such that if a second communication method different from an initially selected first communication method is selected anew, then the priority changing section changes the priority of each of the plurality of communication methods based on the newly selected second communication method.
    • 这里公开了一种信号处理装置,包括:多个帧头检测部,被配置为通过将从外部装置发送的信号的波形与多个不同的通信方式的波形进行比较来确定是否检测到符合多种不同的通信方法中的任何一种的帧头 的预定的不同符号图案; 通信方法选择部,其基于所述帧头检测部的判定结果和所述多个通信方法中的每一个的优先级,选择与所述外部装置进行通信的通信方法; 以及优先级改变部分,其被配置为使得如果重新选择与初始选择的第一通信方法不同的第二通信方法,则优先级改变部分基于新选择的第二通信方法来改变多个通信方法中的每一个的优先级。
