摘要： According to one embodiment, to detect a still subtitle part included as a part of an image in a video signal, the still subtitle detection apparatus detects in pixel units a subtitle part from a video frame formed of pixels. The apparatus includes a subtitle part determination module and a still subtitle detection module. The subtitle part determination module determines, as the subtitle part, a pixel or pixel group on the high-luminance region side (white peak) that neighbors the detection position of an image edge where a luminance level changes or on the low-luminance region side (black bottom) that neighbors the detection position of the image edge where the luminance level changes. When it is detected that the subtitle part remains unchanged by comparing two continuous video frames along the time axis, the still subtitle detection module detects the subtitle part as a still subtitle.

摘要： In a communication terminal where a running application is not managed by an OS (operating system), a message is received without a communication connection being established, and if the message is destined for a running application, receipt of the message is notified to the running application. In mobile device MS, CPU 6 writes in key information area 73 of RAM 7 key information for identifying a Java application which is being run using KVM program 84, using OS software 82 and JAM program 86 stored in nonvolatile memory 8. CPU 6, when receiving a SMS message, and further if a content of the message matches the key information written in key information area 73, writes information that the message has been received in an area reserved in RAM 7 for the running Java application.
