Title:
DEFLECTION DETECTION METHOD FOR TERMINAL CAMERA MODULE, JITTER COMPENSATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/000380
Kind Code:
A1
Abstract:
The present invention relates to the field of image processing. Disclosed are a deflection detection method for a camera module of a terminal, a jitter compensation method and device, capable of eliminating the effect of an included angle between a camera module, and x-axis and y-axis of a gyroscope of a mobile mainboard on the optical anti-jitter compensation of an OIS. The method comprises: a detection means receives a detection image transmitted by a terminal, the detection image being obtained by a standard capturing board (101) of the terminal, the standard board (101) including a contrast icon, and an angle between the contrast icon and the horizontal direction being θ1; the detection means determines an angle θ2 between a contrast icon in the detection image and the horizontal direction; the detection means determines an angle difference between θ1 and θ2 so as to allow the terminal to obtain a compensation displacement of a camera module according to the angle difference, the angle difference being an angle between the camera module of the terminal, and x-axis and y-axis of a gyroscope of a terminal mainboard.
