ABSTRACT:
An imaging device includes a photoreceptor portion including a plurality of photoreceptors arranged in an array, a microlens array including a plurality of microlenses, and a light shielding layer placed between the photoreceptor portion and the microlens array. The light shielding layer has apertures located corresponding to the plurality of photoreceptors. An optical relationship of an actual length d1of an aperture width of the apertures on a side of the photoreceptors, an actual length p of a distance between adjacent microlenses, an equivalent air length t0of a distance between vein and a top of the microlenses, and an equivalent air length t1of a thickness between the top of the microlenses and an aperture position of the apertures on the side of the photoreceptors satisfies:1.36×t1p≤d1≤2.4×t1p+p×t1t0.
