Zusammenfassung: | To provide an image processing system that is able to shorten a time taken to search one channel suitable for first radio communication (WLAN communication) from among a plurality of channels.SOLUTION: While an MFP and a radio terminal are BT connected, a BT communication frequency, which is the center frequency of a BT channel used in BT communication, is stored in a RAM. In a case where a search target distribution formed from a group of BT communication frequencies not separated by not lower than the occupied frequency width of a WLAN channel used in WLAN communication is included in the distribution of BT communication frequencies stored in a RAM when the MFP and the radio terminal are WLAN connected, the minimum frequency and the maximum frequency included in the search target distribution are specified. Then, all WLAN channels satisfying a condition that both the minimum value and the maximum value of the occupied frequency are included in the range of the minimum-maximum frequency range are used as candidate channels, and one of the candidate channels is determined as a WLAN channel used in the WLAN communication.SELECTED DRAWING: Figure 5
【課題】複数のチャンネルの中から第1無線通信(WLAN通信)に適した1つのチャンネルを探索する時間を短縮できる、画像処理装置を提供する。【解決手段】MFPと無線端末とがBT接続されている間、BT通信に使用されたBTチャンネルの中心周波数であるBT通信周波数がRAMに記憶される。MFPと無線端末とのWLAN接続の際、RAMに記憶されているBT通信周波数の分布の中に、WLAN通信で使用されるWLANチャンネルの占有周波数幅以上離れていないBT通信周波数の集まりからなる探索対象分布がある場合、その探索対象分布に含まれる最小周波数および最大周波数が特定される。そして、占有周波数の最小値および最大値の両方が最小−最大周波数の範囲に含まれるという条件を満たすWLANチャンネルの全てが候補チャンネルとされて、候補チャンネルの中の1つがWLAN通信に使用するWLANチャンネルに決定される。【選択図】図5 |
