Abstract
A mobile terminal for capturing an image and a method for controlling the same are provided. The mobile terminal includes a camera unit configured to receive an external image and process the received image to an image frame, and a control unit configured to set a focal point value of the image frame received from the camera unit, wherein the focal point value is a focal point value obtained by correcting a first focal point value extracted according to a first scheme of detecting a focal point value by using a phase difference of the image by using a second focal point extracted according to a second scheme of detecting a focal point by using a comparison value of the image.
Claims20
A mobile terminal comprising:
- a camera unit configured to receive an external image, process the received image and provide an image frame;
- and
- a controller configured to set a focal point value of the image frame,
- wherein the focal point value is set by:
- obtaining a first focal point value according to a first focal point detecting scheme based on a phase difference of the image,
- obtaining a second focal point value according to a second focal point detecting scheme based on a comparison value of the image, and
- setting the focal point value of the received image frame based on the obtained first focal point value and the obtained second focal point value.
A method for controlling a mobile terminal, the method comprising:
- receiving an external image from a camera unit and processing the received image to provide an image frame;
- obtaining a first focal point value of the image frame according to a first focal point detecting scheme based on a phase difference of the image;
- obtaining a second focal point value of the image frame according to a second focal point detecting scheme based on a comparison value of the image;
- and
- setting a focal point value of the image frame based on the first focal point value and the second focal point value,
- wherein, in the setting of the focal point value, when the first focal point value has an accuracy equal to or greater than a preset level, then correction of the first focal point value is not performed.
