Abstract:
A device that sets time in an image processing apparatus, comprising:a channel selection unit having an input and an output, said input receiving signals from both analog and digital channels, said channel selection unit selecting a signal of a desired channel among received signals from said input;a channel decision unit having an input and an output, said input of said channel decision unit connected to said output of said channel selection unit, said channel decision unit determining whether an input signal is from either one of said analog or said digital channels;a time information receiving unit having an input and an output, said input being connected to said output of said channel selection unit, said time information receiving unit receiving current to time information from a signal of one of said digital channels from said output of said channel selection unit; anda controller connected to said output of said channel decision unit and said output of said time information receiving unit, said controller setting the current time based on the current time information from said output of said time information receiving unit if said input of said channel selection unit receives a signal from one of said digital channels, and applying a first control signal from said controller to said channel selection unit if said input of said channel selection unit is determined to be a signal from one of said analog channels, selecting an arbitrary digital channel and set the current time based on the current time information of a signal from said arbitrary digital channel, and then applying a second control signal from said controller to said channel selection unit to output said signal from one of said analog channels.
