Title:
ADAPTIVE AUTOFOCUSING SYSTEM
Document Type and Number:
Japanese Patent JP2017016103
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a phase-detection autofocus system that uses a single two-dimensional (2D) image sensor as an autofocus sensor.SOLUTION: An adaptive autofocusing system enables a number of novel functionalities such as calibration by adaptive selection of pixels for an autofocus collection zone, dynamic optimization of the collection zone for various scene and lightning conditions, as well as use of 2D phase signals in cross-correlation. This freedom in selecting which pixels to use gives rise to an equivalent freedom for the focus points presented to the user, which can be created, moved and scaled according to conditions and scenes.SELECTED DRAWING: Figure 3
