Image collecting system and image collecting method

Abstract

The invention discloses an image collecting system and an image collecting method. The system comprises a fixation point detection device and an image collecting device, wherein the fixation point detection device is used for detecting the position, relative to a user, of a user current fixation point, and the image collecting device is used for conducting focusing and image collecting according to the position, relative to the user, of the fixation point. The fixation point detection device comprises an eye fundus image collecting module, an adjustable lens module and an image processing module, the eye fundus image collecting module is used for collecting an image of the eye fundus of the user, the adjustable lens module is used for adjusting imaging parameters of a light path between the eye fundus image collecting module and the eyes so as to enable the eye fundus image collecting module to obtain the clearest image, and the image processing module is used for calculating the position, relative to the user, of the user current fixation point according to the imaging parameters of the light path between the eye fundus image collecting module and the eyes and the optical axis direction of the eyes when the clearest image is obtained. According to the mage collecting system and the image collecting method, the focusing accuracy and the focusing speed of the image collecting device can be improved.

Description

technical field [0001] The present invention relates to the technical field of image acquisition, in particular to an image acquisition system and method. Background technique [0002] There are many methods for automatic focusing of the image acquisition device, including automatically detecting the viewing direction of the user's eyes, performing depth detection in this direction, and then focusing. For example, Canon's EOS3 SLR camera has an eye-controlled focus function with 45 focus points, which can automatically detect the movement of the eye pupil of the user looking at the camera eyepiece. The eyeball is illuminated by the infrared light-emitting diode installed on the eyepiece frame of the camera, and the infrared light reflected by the eyeball is projected onto the eye control BASIS (Basic Storage Image Sensor). After the system detects the relative relationship between the pupil position of the eyeball and the calibration position, the camera It will recognize w...

Problems solved by technology

In this patent, the position of the lens and / or the image sensor must be moved to make the image reflected in the eyes focus on the image sensor; in addition, since the image scene viewed by the user is random, the image reflected in the user’s eye It is difficult to judge whether the image scene is clearly focused on the image sensor, so its detection accuracy is difficult to guarantee
