Abstract: A camera control technique is provided. An image data processing apparatus includes a raw data processor configured to convert a signal collected by an image sensor into a digital signal, an identification information processor configured to allocate identification information to each video frame obtained by the raw data processor, and a metadata processor configured to write the identification information in metadata of the video frame. An electronic device having the apparatus and an image data processing method are also disclosed.

Abstract: A method for processing an image in a camera device according to the present disclosure includes autofocus photographing to continuously obtain an image by moving a focusing lens at a predetermined focusing interval, extracting a focus value for a focus area of the obtained image, and storing the focus value with the image. The method also includes focus resetting by displaying a representative image of the stored images, and storing an image having the maximum focus value for a focus area of a selected location if the location is selected from the representative image.
