    摘要： A screen output control device of a mobile communication terminal includes a first screen output unit to output a first portion of a web page on a first screen, and a second screen output unit to output a second portion of the web page on a second screen. The first portion is a scaled down version of the web page, and the second portion is part of the first portion. The second portion may be enlarged relative to the first portion to be displayed in a scale that is more visible by a user. A user may navigate the web page through a user input to the first screen or the second screen. Another screen output control device divides a web page into areas, each of which is synchronized with inputs of an operation unit so that an area can be selected for display by entering the corresponding input.

    摘要： In a mobile communication system of multi-cell environment, a pico-cell indicator is installed at predetermined positions for easy cell-registration change of a mobile station from a micro-cell service area to a pico-cell service area. The method for cell registration of the mobile terminal by using the pico-cell indicator includes the steps of determining whether a code signal of the pico-cell indicator is received when the mobile terminal is not in engaged, determining whether a timer in the mobile terminal is in operation when the code signal is input, storing a current micro-cell ID and registering pico-cell when the timer is not in operation, preparing to micro-cell ID when the timer is in operation to register the micro-cell as the operation of the timer is finished, determining whether a code signal is received when the mobile terminal is in engaged in the first step, determining whether the engagement is finished when the code signal is input, and setting timer and storing micro-cell ID when the engagement is finished and registering the pico-cell as the operation of the timer is finished.

    摘要： A character signal display for a camcorder includes a character signal generator for providing needed character data responsive to horizontal and vertical sync signals separated from a selected video signal. According to one aspect of the invention, the vertical sync signal is extracted from the selected video signal by a microcomputer while the horizontal sync signal is extracted from the selected video signal using a Hsync signal oscillator associated with an electronic viewfinder. When an external video signal is input, selection between the external video signal and the camera video signal is arbitrary; when the external video signal is not applied, the camera video signal is preferentially selected. According to another aspect of the invention, circuitry associated with the electronic viewfinder can generate both the horizontal and vertical sync signals needed by the character generator. Therefore, the conventional synchronous signal generator and synchronous signal separator can be omitted from the camcorder. As a result, the manufacturing cost can be curtailed while still providing the desired synchronous signals.
