Dual camera module and optical device

A dual camera module, the dual camera module comprising:

• a first camera module comprising a first circuit layer and a second circuit layer, wherein a portion of the second circuit layer is disposed on and in direct contact with the first circuit layer, a first image sensor disposed on a bottom surface of the second circuit layer, and a first lens disposed above the first image sensor, wherein the first circuit layer and the second circuit layer each has a through hole and the first image sensor is disposed in the through hole of the first circuit layer and vertically underneath the through hole of the second circuit layer;
• a second camera module comprising a substrate, a second image sensor disposed on an upper surface of the substrate, wherein the upper surface of the substrate is horizontally coplanar with an upper surface of the second circuit layer and a bottom surface of the substrate is horizontally coplanar with a bottom surface of the first circuit layer, and a second lens disposed above the second image sensor;
• a first window disposed above the first lens;
• and
• a second window disposed above the second lens;
• wherein the second camera module has an angle of view wider than that of the first camera module,
• wherein the second image sensor is configured to be disposed at a position higher than that of the first image sensor such that an area of the second window forms an angle of view for the second camera module wider than an angle of view for the first camera module
• wherein a vertical position of an upper end of the first lens is higher than a vertical position of an upper end of the second lens, and
• wherein a vertical position of a lower end of the first lens is lower than the vertical position of the upper end of the second lens and higher than a vertical position of a lower end of the second lens.
