When the user needs to confirm whether the camera module corresponds to the iris area of the user through the display screen of the mobile phone, the line of sight is moved to The display screen of the mobile phone, and once this happens, the camera module cannot collect the user's iris image or the collected iris image is relatively blurred when the eyeball does not return to the position corresponding to the camera module.
In the actual shooting process, the user needs to change the position of the eyeball back and forth between the optical axis of the camera module and the display screen of the mobile phone to confirm and correct the distance between the camera module and the user multiple times by moving the line of sight. Correspondence between iris areas, such a process not only makes users feel tired but also tends to lose sight of one another, so that it is impossible to obtain a better iris image or even fail to collect an iris image

The invention discloses a camera device and a method for collecting iris images through it, wherein the camera device includes a camera module, wherein the camera module further includes a photosensitive chip and an optical lens, and the optical lens is eccentric The photosensitive path is arranged on the photosensitive chip, and the light reflected by the object is received by the photosensitive chip after passing through the edge position of the optical lens to perform photoelectric conversion, so that the camera module is suitable for The image of the object to be photographed that deviates from the central axis of the optical lens is collected.
Description
technical field [0001] The present invention relates to an optical imaging device, in particular to an imaging device, wherein the imaging device provides a photosensitive chip and an optical lens arranged eccentrically, so that the light reflected by the object to be photographed deviates from the central axis of the optical lens The light can be received by the photosensitive chip after passing through the edge position of the optical lens to perform photoelectric conversion and form an image. In addition, the present invention also relates to a method for collecting iris images by means of a camera device, which allows the user to obtain the user's iris images while viewing the display screen. Background technique [0002] Camera modules based on optical imaging technology have been widely used and popularized in many electronic equipment fields represented by mobile electronic equipment. The camera module obtains photos or helps users complete related operations by coll...
