Patent ID: 8547472

Claim:
An image pickup device comprising: signal processing means for processing a W signal which is generated without performing wavelength separation and generated by separating a luminous signal into wavelength components of two or more colors by use of a sensor unit comprising two-dimensionally arranged pixels including W signal pixels and color pixels to which a wavelength separating unit for separating light wavelengths is arranged at front face of photoelectric converting element which convert the luminous signal condensed by an optical lens into electric signals, wherein each area of light receiving surfaces of the two-dimensionally arranged pixels are the same for all the W signal pixels and color pixels; and the wavelength separating unit is constituted of micro-lenses each of which condenses light for each pixel and color filter layers which separate light wavelengths, and a micro-lens corresponding to the W signal to which a filter layer which does not separate light wavelengths is formed to be smaller in size than the micro-lenses to which color filter layers are arranged.
