Abstract
When an endoscopic imaging system is employed in, for example, the department of otorhinology, a color processing expansion substrate, a still image production expansion substrate, and a still image compression/recording substrate are stacked on an expansion connector formed on a main substrate and are thus connected to the main substrate. A data bus and an address bus extending from a control unit mounted on the main substrate are linked to the expansion substrates. A sync signal generator outputs various kinds of sync signals including a clock signal CLK, a horizontal sync signal HD, a vertical sync signal VD, a field identification signal FLD, and a composite sync signal CSYNC to the expansion substrates.
