A camera module includes an imaging lens assembly and an image sensor. The imaging lens assembly includes a plastic optical element with a light-blocking layer disposed on its transparent surface. The plastic optical element includes an optical effective area, and a peripheral region of the light-blocking layer forms a specific shape around the optical effective area so as to define an aperture region. The peripheral region includes a main portion and a compensation portion. The main portion is physically contacted with the transparent surface. The compensation portion is disposed on an edge of the main portion adjacent to the optical effective area, and an optical density of the compensation portion is lower than an optical density of the main portion. The image sensor is disposed on an image side of the imaging lens assembly for defining a maximum image height and further defining a relative illumination.

Camera module, imaging module and electronic device

An imaging lens assembly includes, in order from an object side to an image side, a first lens element and a second lens element. The first lens element includes a first frustum surface and a second frustum surface. The first frustum surface is disposed on a side of the first lens element facing towards the second lens element. The first frustum surface and the second frustum surface are disposed on the same side and coaxial, and the second frustum surface is closer to an optical axis than the first frustum surface to the optical axis. The second lens element includes a first corresponding frustum surface and a second corresponding frustum surface. The first corresponding frustum surface is corresponding to the first frustum surface. The second corresponding frustum surface is corresponding to the second frustum surface.

Imaging lens assembly, image capturing apparatus and electronic device

An imaging lens assembly has an optical axis, and includes a plurality of optical elements. The optical elements include a light blocking sheet, and the light blocking sheet includes a through hole surface, a first surface, a second surface, a peripheral surface and a plurality of basin structures. The through hole surface surrounds the optical axis. The first surface and the second surface are connected to and surround the through hole surface. The peripheral surface is connected to the first surface and the second surface, and the peripheral surface is farther from the optical axis than the through hole surface from the optical axis. The basin structures are arranged in interval and around the optical axis, each of the basin structures is caved in from the first surface to the second surface, and each of the basin structures protrudes on the second surface.

An imaging lens assembly has an optical axis and includes an annular structure located on an object side of the imaging lens assembly and surrounds the optical axis. The annular structure is located on an object side of the imaging lens assembly, surrounds the optical axis, and includes a first through hole, a second through hole, a first frustum surface, a second frustum surface and a third frustum surface. The first through hole is disposed on an object side of the annular structure, and the second through hole is disposed on an image side of the first through hole. The first frustum surface is disposed on the image side of the first through hole. The second frustum surface is disposed on an object side of the second through hole. The third frustum surface is disposed on an image side of the second through hole.

Imaging lens assembly, image capturing device and electronic device

An imaging lens assembly includes a plurality of optical elements and an accommodating assembly, wherein the accommodating assembly is for containing the optical elements. The accommodating assembly includes a conical-shaped light blocking sheet and a lens barrel. The conical-shaped light blocking sheet includes an out-side portion and a conical portion, and the conical portion is connected to the out-side portion. The conical portion includes a conical structure tapered from the out-side portion toward one of an object-side and an image-side along the optical axis. The lens barrel is disposed on one side of the conical portion. The optical elements include a most object-side optical element, a most image-side optical element and at least one optical element. The conical structure of the conical-shaped light blocking sheet is physically contacted with only one of the lens barrel, the most object-side optical element and the most image-side optical element.
