摘要:
Disclosed is a digital image compression and decompression method and apparatus for dividing a supplied digital image signal into blocks of predetermined size, performing variable-length coding of the signal, separating the signal with respect to principle information and remaining information, and controlling the record format so that each type of information is alternately recorded on a recording medium in an equal interval whenever recording the compressed information and decompressing the information, according to the reverse order, during decoding. Also, the function for extracting an activity in two steps during coding and then controlling the permitted number of bits of the variable length coding is provided. Accordingly, the coding efficiency is improved and the circuitry is simplified so that the price of the end product can be lowered.
摘要:
A method of controlling a digital photographing apparatus is provided. Also provided is a digital photographing apparatus using the method and a computer readable recording medium having recorded thereon a computer program for executing the method. The method includes displaying a residual image of a background image; setting a partial area of an area on which the residual image is displayed; capturing an image including a subject; extracting a subject image corresponding to the partial area from the image; and generating a composite image by combining the background image and the subject image.
摘要:
A digital photographing apparatus includes an optical system, an optical image stabilization (OIS) unit adapted to move the optical system, and a digital signal processor in communication with the OIS unit. The digital signal processor sets an operating ratio of the OIS unit by reducing the operating ratio to a previously set value of 100% or below after a still image or a moving picture is captured, and the OIS unit moves the optical system while a live view mode is turned on.

Provided are a digital image processing apparatus having improved hand-shake compensation performance by measuring a distance between the digital image processing apparatus and a subject to be photographed and performing hand-shake compensation by reflecting the measured distance, and a method of controlling the digital image processing apparatus. The method of controlling the digital image processing apparatus includes measuring a subject distance corresponding to a distance between a body of the digital image processing apparatus and a subject to be photographed; setting a first tuning coefficient for tuning hand-shake compensation according to the subject distance; sensing hand-shake that causes the body to shake; and compensating for the hand-shake by incorporating the first tuning coefficient.
