Abstract:
1. A color solid-state imaging device used in combination with an interference-type infrared cut filter, coloring material which is contained in or formed on any of layers provided within an incident light path in the color solid-state imaging device or in combination with the interference type-infrared cut filter so that all incident light on the color solid state imaging device passes through the coloring material, wherein the coloring material absorbs the incident light within a wavelength range in which a cut wavelength of the interference-type infrared cut filter shifts toward shorter wavelengths when the incident light obliquely enters the interference-type infrared cut filter so that the shift of the cut wavelength of the of the interference-type infrared cut filter that produces a noticeable deficiency in red coloring at the periphery of the color solid state imaging device is reduced by the coloring material absorption of incident light, and the coloring material has a light transmittance of at least 60 percent at wavelengths within the range of 420 nm to 605 nm.
