Wireless terminal having a pre-scan during image display
View Patent ↗In an imaging device having a wireless module, an increase in undesired power consumption is inhibited, and a time required before establishment of a communications channel with a wireless terminal is shortened. In response to depression of a playback button performed by user by way of an operation section, a control section performs a pre-scan by way of a wireless module before a main scan responding to a request for wireless connection. When having received a request for wireless connection, the control section accepts designation of a wireless terminal serving as a destination of transmission from the user by utilization of a result of the pre-scan prior to a result of the main scan responding to the request for wireless connection.
1. A wireless terminal having a plurality of modes, including an image display mode for displaying an image stored in memory, the wireless terminal comprising:
a detection section for detecting that the image display mode is selected;
a pre-scan execution section for performing pre-scan for discovery of a wireless area network by way of a wireless module when the detection section detects the image display mode is selected by a user;
a designation acceptance section for accepting designation of data to be transmitted; and
a transmission control section configured to:
perform a main scan for searching for a wireless terminal using the wireless area network by way of a wireless module in response to a request for wireless connection from the user;
accept designation by the user of a wireless terminal to serve as a destination of transmission in accordance with a result of the main scan; and
transmit the data to be transmitted to the designated wireless terminal by way of the wireless module;
wherein user designation of the wireless terminal to serve as a destination of transmission is facilitated by a result of the pre-scan prior to a result of the main scan.
2. The wireless terminal according to claim 1 , wherein the plurality of modes comprises an image capture mode.
3. The wireless terminal according to claim 1 , further comprising:
a storage device for storing data, wherein:
a pre-scan determination section determines, after turning-on of power, a pre-scan to be necessary when a remaining storage capacity of the storage device is smaller than predetermined minimum storage capacity.
4. The wireless terminal according to claim 1 wherein a duration of the pre-scan is shorter than a duration of the main scan.
5. The wireless terminal according to claim 1 , wherein a result of the pre-scan includes a display size of data capable of being displayed on a wireless terminal which becomes a candidate for a destination of transmission; and
the transmission control section, before accepting designation of data to be transmitted, generates data having been adjusted according to the display size sequentially for each set of data which become a candidate for data to be transmitted, and transmits, to a wireless terminal serving as a destination of transmission by way of the wireless module, the data whose size adjusted in conformity to data to be transmitted when having accepted designation of a wireless terminal as a destination of transmission.
