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.

Abstract: An image pick-up apparatus includes an object lens, an image transmission device, and an image-sensing device. The object lens projects an image of an object to be picked-up. The image transmission device has an image-receiving side disposed to receive the image projected by the object lens, an image output side, and an image-transmitting portion coupled optically with the image-receiving side and the image output side. The image-receiving side has a curvature corresponding to curvature-of-field characteristics of the object lens so as to enable correction of aberrations introduced by the object lens into the image projected by the object lens. The image-sensing device is coupled optically with the image output side of the image transmission device for sensing a corrected image of the object to be picked-up that is provided by the image transmission device at the image output side.
