摘要:
According to the present invention, it is possible to improve the usability of an automatic image editing apparatus by finding subject-captured scenes from inter-frame motion vectors for automatic editing of motion images. If the result of analyzing inter-frame motion vectors indicates that all motion vectors in a region are the same in direction and magnitude, this region is judged as a subject being followed. Thus, it is possible to automatically extract and edit subject-captured scenes. In addition, the edited images namely plural scenes may be displayed either in the same order as edited or in the order of importance. As well, similar scenes may be combined into a single image sequence. Thus, it is possible to provide improved usability to the viewer.
摘要:
A semiconductor laser driving circuit has a circuit protection function at low temperature and includes a voltage current converter that converts an input voltage Vin, which is determined according to a desired light brightness of the semiconductor laser to be driven, into a current. A current limiter limits an output current of the voltage current converter to a specified current value or less. An output amplifier amplifies the output current of the voltage current converter and supplies the amplified current as a drive current to the semiconductor laser. A temperature detection circuit detects a low temperature state and, in the low temperature state, decreases the specified current value of the current limiter.

摘要:
A gas burner having first flame openings for discharging a stable and self-combustible high-concentration gas and second flame openings for discharging an unstable and non-self-combustible low-concentration gas, with the first and second flame openings being disposed alternately with each other. The effect of stable flame formations at the first flame openings assists stabilization of flame formations at the second flame openings adjacent thereto. Consequently, the gas burner as the whole may have a high air excess ratio to reduce its NOx generation and to prevent incomplete combustion. Further, if a rectifying member is provided in the second flame opening, it becomes possible to enlarge the opening area of the second flame opening without disturbing its flame formation, whereby the burner will achieve further reduction in NOx generation and combustion noise and also improvements in its combustion load and ignition performance.

In a private branch exchange having an optimum route selecting function of selecting an optimum route by taking the destination, day of the week, time zone, permissive class of the extension terminal and the like into consideration when a call originating request from the extension terminal is generated, adequately processing dial number and outputting the same to an outgoing line so as to use the route, the route is selected by taking usage rates of the respective routes into consideration. Further, in the route selecting process, the route is selected by taking communication time (estimated value) into consideration. In an exchange system which is constructed by connecting plural private branch exchanges and in which, when an optimum route connected to one exchange is busy, dial number for permitting use of the optimum route is output via another exchange, the optimum route is not immediately selected via another exchange, but a substantially optimum route or routes which are substantially the same as the optimum route and connected to the given exchange are selected so that the dial number will be output from the given exchange with maximum possibility.
