Abstract

The invention provides an image processing method and an electronic device. The method comprises the following steps of obtaining a first preview image of a user through an image obtaining device and displaying the first preview image; identifying the first area of the biological feature of the user from the first preview image and marking the first areaon the first preview image as a first image marker; determining whether the relative location of the user and the imaging obtaining device satisfies a preset condition according to the first preview image and the first image marker; when it is determined that the relative location of the user and the imaging obtaining device does not satisfy the preset condition, carrying out preset image processing to the first preview image and the first image marker, thus generating a second preview image and a second image marker, and instructing that the relative location of the user and the imaging obtaining device does not satisfy the preset condition in a preset mode.

Description

technical field [0001] The present application relates to image processing methods and electronic devices. Background technique [0002] With the popularization of mobile devices, the security problems associated with mobile devices have become more and more obvious. For example, users can unlock mobile devices through various biometric identifications, such as fingerprint unlocking. At present, because iris recognition is highly accurate and difficult to forge in biometric technology, and can be well integrated into mobile devices such as mobile phones, it has received more and more attention. [0003] However, when the iris camera is used for iris recognition, the relative positions of the user and the iris camera need to meet predetermined conditions. For example, it is required that the user faces the iris camera directly and the distance from the iris camera meets certain requirements. When the relative position of the user and the iris camera does not meet the prede...
