When the normal mode is selected, a controller drives theflasher to display anormal range. When the zoom mode is selected, the controller divides thenormal range into afirst range and a second range, compresses the first range into a compressedrange, enlarges thesecond range into an enlarged range, and drives the flasher to display theenlarged rangeinterleaved with the compressed range.
