| 摘要 |
An image pickup device includes a signal processing unit which processes a signal generated by separating a luminous signal into wavelength components of two or more colors by use of a sensor unit including two-dimensionally arranged pixels to which a wavelength separating unit for separating light wavelengths is arranged at a front face of a photoelectric converting element which converts the luminous signal condensed by an optical lens unit into electric signals, wherein the optical lens unit includes at least one optical lens having different focusing positions in accordance with the wavelengths of the luminous signal, and the signal processing unit includes an outline signal generating unit which extracts an outline signal from an output signal of the sensor unit.
