Abstract

The invention provides an image processing method and electronic equipment. The method includes: acquiring a first preview image of the user through an image acquisition device and displaying the first preview image; identifying a first region of the user's biometric feature from the first preview image, and displaying the first preview image in the first preview image. marking the first area on the image as a first graphic mark; determining whether the relative position of the user and the image acquisition device satisfies a predetermined condition according to the first preview image and the first image mark; and when determining that the user and the When the relative position of the image acquisition device does not meet the predetermined condition, perform predetermined image processing on the first preview image and the first graphical mark to generate a second preview image and a second graphical mark, thereby instructing the user in a predetermined manner The relative position with the image acquisition device does not meet the predetermined condition.

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...
