Abstract
The present disclosure relates to a method of contrast-based autofocus for an image capture device, the method comprising: obtaining first sensor data representative of a first contrast characteristic of one or more images captured with a first focus setting, the first sensor data comprising first data values from respective image zones of the one or more images, an image zone being a region of an image; obtaining second sensor data representative of a second contrast characteristic of the one or more images, the second sensor data comprising second data values from respective image zones of the one or more images; processing the first sensor data by performing a first filtering operation on the first sensor data to obtain a first contrast characteristic metric, the first filtering operation being determined by the first contrast characteristic and based on the first sensor data of at least one image zone on a first image of the one or more images and one or more image zones related to the at least one image zone; processing the second sensor data by performing a second filtering operation on the second sensor data to obtain a second contrast characteristic metric, the second filtering operation being determined by the second contrast characteristic and based on the second sensor data of the at least one image zone on the first image and one or more image zones related to the at least one image zone; and generating a contrast metric of the first focus setting based on the first contrast characteristic metric and the second contrast characteristic metric.
