Problems solved by technology

[0002] In recent years, electronic products are becoming thinner and lighter, so the matching imaging device also needs to be miniaturized. However, although the known imaging lens system can provide a miniaturized design, it is difficult to meet the requirements of large viewing angle and short overall length at the same time. , so it is difficult to mount on electronic devices that are thin and light and require a large viewing angle (such as mobile phones, portable devices, portable video recorders, optical recognition devices or other electronic devices, etc.)

Abstract

The invention discloses an imaging lens system, an imaging device and an electronic device. The imaging lens system sequentially includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from the object side to the image side. The first lens has negative refractive power. The fourth lens has positive refractive power, and its object-side surface and image-side surface are both aspherical. The fifth lens has negative refractive power, its object-side surface is concave near the optical axis, its image-side surface is convex near the optical axis, and both its object-side and image-side surfaces are aspherical. The image-side surface of the sixth lens is concave near the optical axis and has at least one convex surface off-axis, and both the object-side surface and the image-side surface are aspherical. When certain conditions are met, it can meet the requirements of wide viewing angle and miniaturization. The invention also discloses an image-taking device with an image-taking lens system and an electronic device with the image-taking device.

Description

technical field [0001] The present invention relates to an image capturing lens system and an image capturing device, and in particular to an image capturing lens system and an image capturing device applied to an electronic device with both miniaturization and wide viewing angle. Background technique [0002] In recent years, electronic products are becoming thinner and lighter, so the matching imaging device also needs to be miniaturized. However, although the known imaging lens system can provide a miniaturized design, it is difficult to meet the requirements of large viewing angle and short overall length at the same time. , so it is difficult to mount on electronic devices that are thin and light and require a large viewing angle (such as mobile phones, portable devices, portable video recorders, optical identification devices or other electronic devices, etc.). Contents of the invention [0003] The present invention provides an image-taking lens system, an image-tak...
