LIGHT-CONDENSING ELEMENT

Theres is provided a light-condensing element capable of condensing incident light having different wavelengths by a common light-condensing element. An integrated pattern is formed by integrating concentric wavelength-specific patterns set to condense incident light for each of a plurality of different wavelengths. In integrating the wavelength-specific patterns of the incident light having different wavelengths, in a case where the different wavelength-specific patterns include transmission regions that transmit the incident light and are superimposed on each other, the integrated pattern forms dithering to mix color filters formed in the transmission regions of the wavelength-specific patterns. The present disclosure may be applied to an imaging device.
