ABSTRACT:
A digital camera and a method for manually focusing the digital camera are disclosed. The digital camera includes an image sensing unit, a buffer memory unit, an image processing unit, and an image display unit. The image sensing unit senses a signal and produces a full-view area image and a focus-view area image. The image sensing unit selectively outputs the full-view area image and the focus-view area image to the buffer memory unit. When the image sensing unit outputs the focus-view area image to the buffer memory unit, the buffer memory unit outputs the focus-view area image to the image display unit for manual focusing operation by users.
