Abstract:
1. A solid-state image pickup apparatus, comprising: a photoelectric converter formed on a light incident side in a substrate; a wiring portion formed on a side of the substrate that is opposite to the light incident side; a micro lens formed on a light incident side of the photoelectric converter; and an adjustment film to adjust variation of light reception sensitivities in the photoelectric converter with respect to wavelengths of light that enter the photoelectric converter through the micro lens, the adjustment film being formed between the photoelectric converter and the micro lens and being in contact with the micro lens and an antireflection film, wherein the adjustment film provides a transmittance that has a period between successive amplitude peaks in an average transmittance of light through the adjustment film measured at 10 nm wavelength intervals, the period being shorter than a wavelength difference between a center wavelength of blue light and a center wavelength of green light, the transmittance being a rate at which light incident at 0 to 90 degrees with respect to an optical axis of the micro lens reaches the photoelectric converter, and wherein when the solid-state image pickup apparatus receives light in a blue band and a green band, a difference of the light reception sensitivities is averaged.
