Patent ID: 8248539

Claim:
A channel selecting device comprising: a tuner unit performing an automatic scanning process of scanning carrier signals while sequentially shifting a channel-selection frequency in a predetermined frequency range, selecting a broadcast wave signal of the channel-selection frequency corresponding to supplied frequency information, and frequency-converting the broadcast wave signal into an intermediate frequency signal; and a demodulation unit receiving the intermediate frequency signal from the tuner unit, checking whether a desired carrier exists, setting a carrier frequency as the channel-selection frequency when it is checked that the desired carrier exists, performing a first process of determining whether a current zone is a zone of which a frequency should be set lower than the channel-selection frequency so as to raise the channel-selection frequency and a second process of determining whether the current zone is a zone of which a frequency should be set higher than the channel-selection frequency so as to lower the channel-selection frequency, and setting the channel-selection frequency as a target just-tuning frequency.
