摘要： In an optical zoom tracking apparatus and method, and a computer-readable recording medium for performing the optical zoom tracking, the optical zoom tracking apparatus commands a focus lens to move according to a continuous zooming operation, such that a clear image can be maintained while the image is continuously zoomed in or out, resulting in the effective use of limited power if an optical zoom function of a digital camera or mobile phone is executed. The optical zoom tracking apparatus includes: a zoom lens, a focus lens interoperable with the zoom lens, a zoom-lens drive moving the zoom lens, a focus-lens drive moving the focus lens, and a focus-lens controller for determining a moving distance of the focus lens according to a moving distance of the zoom lens, and transmitting a control signal corresponding to the moving distance of the focus lens to the focus-lens drive.

摘要： In a Plasma Display Panel (PDP) power control apparatus, an internal voltage of a power supply is detected, and a determination is made as to whether an Alternating Current (AC) power input to the power supply has been turned off on the basis of the detected internal voltage. The output of the power supply is controlled according to a predetermined sequence based on a result of the determination to turn off the PDP. The apparatus rapidly and accurately senses that the AC power has been turned off and performs a predetermined power off sequence to prevent damage to a driving circuit and to prevent the picture quality of the PDP from being degraded.

摘要： Provided are a discrete AF control method and an error correcting method of a camera module using a diffraction device. In the method, a focus is moved to a (the number of all positions/m)-th position, and a focusing value at a start position is compared with that at the (the number of all positions/m)-th position. A focus is moved by two positions in a first direction according to the comparison result. If a position having a maximum focusing value is passed, a focus is moved by one position in a direction opposite to the first direction and a location (corresponding to an n-th position) is stored. Focusing values of the n-th position, an (n−1)-th position, and an (n−2)-th position are compared with one another to determine a maximum focus location, m being an integer equal to or greater than 2.

摘要： A plasma display panel (PDP) driver and PDP gray scale representation method for applying a sustain pulse based subfield arrangement and address light for representation of gray scales and improving representation performance of gray scales. Inverse gamma correction is performed on input image signals so as to represent inverse gamma correction gray scales corresponding to a number of sustain pulses and address light. The inverse gamma correction gray scale is inverted into a subfield based on the number of sustain pulses so as to represent the gray scale through address light and light caused by the number of sustain pulses.
