Title:
IMAGING LENS, IMAGING DEVICE, AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2013/187405
Kind Code:
A1
Abstract:
Provided are an imaging lens in which the total length has been shortened, and an imaging device and a mobile terminal that can achieve compactness by using the same. Actual angle of view for incidence into the imaging lens can be kept small, even if the focal distance is unchanged, by generating positive distortion aberration in the imaging lens. Because positive distortion aberration is generated, a subject body image for which a solid-state imaging device receives light becomes distorted in a so-called bobbin shaped distortion, which is different from conventional barrel-shaped distortion; therefore, by processing an image signal output by the solid-state imaging device in an image processing unit, the distorted image can be corrected on the basis of the positive distortion aberration for the distortion generated by the imaging lens, and an image with no unpleasant sensation when the image is viewed after correction is obtained.
