Claim:
1. A mobile terminal comprising: a camera 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, determining a difference between the first focal point value and the second focal point value, determining accuracy based on the determined difference, setting the focal point value of the image frame by changing an error of the first focal point value based on the determined difference when the accuracy is determined to be less than a preset level, and setting the focal point value as the first focal point value of the image frame when the accuracy is determined to be equal to or greater than the preset level, wherein the controller sets the obtaining of the second focal point value not to be performed any longer when the accuracy is determined to be equal to or greater than the preset level, wherein in response to a preset type of touch at one of a first and second objects that are displayed on a touch screen, the controller changes the error of the first focal point value based on the second focal point value.
