    • Wireless communication is carried out between devices. A highest frequency band is selected. When the selected frequency band includes an unused channel in which no disturbing wave is present, a maximum transmission rate at which a received field strength value exceeds a threshold value is determined. When the selected frequency band does not include an unused channel or one in which no disturbing wave is present or there is no transmission rate associated with the selected frequency band at which the received field strength value exceeds the threshold value, the next highest frequency band is successively selected and the above is repeated. When the maximum transmission rate is successfully determined, communication is initiated using the unused channel of the selected frequency band at the maximum transmission rate as a communication channel.
    • 在设备之间进行无线通信。 选择最高频带。 当所选择的频带包括不存在干扰波的未使用信道时,确定接收到的场强值超过阈值的最大传输速率。 当所选择的频带不包括未使用的信道或其中不存在干扰波的信道或者与所接收的场强值超过阈值的所选频带不相关的传输速率时,下一个最高频带为 依次选择并重复上述。 当成功确定最大传输速率时,以最大传输速率的所选频带的未使用信道作为通信信道进行通信。

    • A method of processing original still picture data representing an original still image and stored in a video memory and storing processed still picture data representing a processed still image in a predetermined location of the video memory comprising the steps of setting an XY orthogonal coordinate system on the video memory, setting a reference line parallel to one of the X and Y axes of the orthogonal coordinate system and passing through a point of intersection of lines, each of which connects corresponding pixels of the original and processed still images, moving multiples the pixel data on a line of the original still image parallel to the reference line and furthest from the reference line to addresses of the video memory forming a line of the processed still image, and repeating the preceding step for pixel data on lines of the still image parallel to the reference line and second furthest from the reference line and succeeding lines, to thereby store the processed still picture data representing the processed still image in the video memory. An apparatus employing this method for processing original still picture data is also provided.
    • 一种处理表示原始静止图像并存储在视频存储器中的原始静止图像数据并将处理后的静止图像数据存储在视频存储器的预定位置的方法,包括以下步骤:在 视频存储器,设置与正交坐标系的X轴和Y轴之一平行的参考线,并通过每个连接原始和处理的静止图像的相应像素的行的交点,将像素数据 在原始静止图像的平行于参考线并且距离参考线最远的线上,形成处理后的静止图像的线的视频存储器的地址,并且对于静止图像的行上的像素数据重复上述步骤 参考线和距离参考线和后续线最远的参考线,从而存储经处理的静止图案 表示视频存储器中处理的静止图像的数据。 还提供了采用这种处理原始静止图像数据的方法的装置。
