Problems solved by technology

[0002] At present, the products on the market must use a separate proximity sensor in order to realize the proximity detection function. The cost of a stand-alone device is several RMB, and the cost is relatively high. Moreover, the proximity sensor uses the image sensor to passively receive light, and the imaging quality is poor in dark light environments.

Abstract

The present invention relates to a approach detection control method and a related device. The method includes: detecting the ambient light intensity of the current environment; determining light compensation information according to the ambient light intensity; performing light compensation according to the light compensation information during image collection to collect a reference image, There is an overlapping period between the supplementary light period of light compensation and the exposure period of image acquisition, and the duration of the overlapping period is longer than the preset duration, and the preset duration is the exposure duration of at least one pixel point; the distance between the detected target and the electronic device is calculated according to the reference image The reference distance; approach control based on the reference distance. The embodiments of the present application are beneficial to improving the accuracy of proximity detection performed by electronic devices.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and in particular to an approach detection control method and a related device. Background technique [0002] At present, products on the market must use a separate proximity sensor to realize the proximity detection function. The cost of a single device is several RMB, which is relatively high. Moreover, the proximity sensor uses an image sensor to receive light passively, and the imaging quality is poor in dark light environments. Contents of the invention [0003] Embodiments of the present application provide an approach detection control method and a related device, in order to improve the accuracy of approach detection performed by electronic equipment. [0004] In the first aspect, an embodiment of the present application provides a method for approach detection control, which is applied to an electronic device, and the method includes: [0005] Detect the ambient...
