Abstract: A method and an apparatus are provided for capturing a moving image and a still image. Moving-image capturing is ceased, when a still image-capturing request is generated. Still-image capturing operation parameters are set in the image sensor. The image sensor is exposed to generate still-image data. Moving-image capturing operation parameters are set in the image sensor, when generation of the still-image data is complete. The image sensor is exposed to generate the moving-image data. The still-image data is quality-processed and compressed to generate still-image frame data. Moving-image frame data generated by quality-processing and size-adjusting the moving-image data are connected and compressed to generate a moving-image stream. Quality-processed virtual moving-image frame data is generated using the still-image data. The quality-processed virtual moving-image frame data is inserted into a loss section of the moving-image stream corresponding to a period in which the moving-image capturing is ceased.

Abstract: A method and apparatus are provided for recognizing characters in a portable terminal with a scan module. Scanned image data is generated by the scan module by scanning a scan target through a scanning-light input/output panel provided on an external surface of the portable terminal as the portable terminal moves across the scan target. Part of the scanned image data is deleted when a current moving speed of the portable terminal is less than a lower limit of an optimal scan speed range, and character recognition is performed on remaining scanned image data. Image data most similar to the scanned image data is detected from a previously stored correction image database when the current moving speed is greater than an upper limit of the optimal scan speed range, and characters corresponding to the detected image data are output as character recognition results.

The filter holder, on which the thin film filters are mounted, is fabricated separately from the module body and houses active elements, such as the laser diode and photo diodes. The filter holder is inserted into the module body thereafter, so the optical module is easily fabricated at a low cost and in a simple manner.
