Abstract
A digital photographing apparatus that is capable of detecting the shaking of the apparatus by using an autofocusing (AF) process and a method of controlling the digital photographing apparatus are provided. These involve calculating a first focal value while focusing on an object by performing the AF process and comparing the first focal value with a second focal value of a location on an image captured by actually photographing the object. This location corresponds to a location corresponding to the first focal value. As a result of these features, the shaking of the digital photographing apparatus can be detected.
Claims20
A method of controlling a digital photographing apparatus that performs an autofocusing process, the method comprising:
- recognizing an object and generating a first image signal from the object;
- calculating a first focal value by performing the autofocusing process on the first image signal;
- photographing the object so as to generate a second image signal;
- calculating a second focal value by performing the autofocusing process on the second image signal;
- and
- comparing the first focal value with the second focal value so as to determine whether the digital photographing apparatus is shook.
A digital photographing apparatus comprising:
- an image sensing unit recognizing an object so as to generate a first image signal and photographing the object so as to generate a second image signal;
- and
- an autofocusing unit calculating a first focal value from the first image signal, calculating a second focal value from the second image signal, and comparing the first focal value with the second focal value so as to determine a degree to which an image is blurred.
