Patent ID: 8013928

Claim:
An image pickup device comprising: a signal processing unit for processing at least a R (red) signal component, a G (green) signal component and a B (blue) signal component generated by separating a luminous signal into wavelength components of the R, G and B signal components by use of a wavelength separating unit provided in a sensor unit comprising two-dimensionally arranged pixels to which the wavelength separating unit is arranged at a front face of a photoelectric converting element which converts the luminous signal condensed by an optical lens unit into an electric signal, wherein the optical lens unit includes at least one optical lens having a first focusing position in accordance with the B wavelength component and a second focusing position in accordance with the R wavelength component, the focusing position of the B wavelength component being around 30 cm, the focusing position of a G wavelength component is from 50 cm to 1 m and the focusing position of the R wavelength component being equal to or longer than 1 m, and the signal processing unit includes an outline signal generating unit for extracting an outline signal from the electric signal generated in the sensor unit.
