In addition, the frequency of the horn may be set to different ranges according to the type of the vehicle 100.

For another example, the predetermined condition may be that the duration of the detected voice signal is longer than a predetermined time. When a traffic accident occurs, the horn sounds for a long time, while the horn sounds for a short time can be irrelevant.

The image recording apparatus 200 may record an image and store it in the second storage unit 248 (S1300).

Reference numerals have been described in the embodiments shown in the drawings, and specific terms are used to describe the embodiments, but the present invention is not limited by the specific terms, and the embodiments are all configurations that can be generally considered by those skilled in the art. Elements.

The embodiment may be represented by functional block configurations and various processing steps. These functional blocks can be implemented with various numbers of hardware or/and software configurations that perform specific functions. For example, an embodiment may be configured with integrated circuits such as memory, processing, logic, look-up tables, etc., which may perform various functions by control of one or more microprocessors or other control devices. You can hire them. Similar to how the components of the present invention can be implemented in software programming or software components, embodiments include C, C++, including various algorithms implemented in a combination of data structures, processes, routines or other programming components. , Can be implemented in programming or scripting languages such as Java, assembler, etc. Functional aspects can be implemented with algorithms running on one or more processors. In addition, the embodiments may employ conventional techniques for electronic environment setting, signal processing, and/or data processing. Terms such as “mechanism”, “element”, “means”, and “configuration” can be used widely and are not limited to mechanical and physical configurations. The term may include the meaning of a series of software routines in connection with a processor or the like.

The specific implementations described in the embodiments are examples, and do not limit the scope of the embodiments in any way. For brevity of the specification, descriptions of conventional electronic configurations, control systems, software, and other functional aspects of the systems may be omitted. In addition, the connection or connection members of the lines between the components shown in the drawings are illustrative examples of functional connections and/or physical or circuit connections, and in the actual device, alternative or additional various functional connections, physical Connections, or circuit connections. In addition, unless specifically mentioned, such as “essential”, “importantly”, etc., it may not be a necessary component for application of the present invention.

In the specification (especially in the claims) of the embodiment, the use of the term “above” and similar indication terms may be in both singular and plural. In addition, in the case where the range is described in the embodiment, as including the invention to which the individual values belonging to the range are applied (if there is no contrary description), it is the same as describing each individual value constituting the range in the detailed description. . Finally, unless there is an explicit or contradictory description of steps constituting the method according to the embodiment, the steps may be performed in a suitable order. The embodiments are not necessarily limited to the order in which the steps are described. The use of all examples or exemplary terms (eg, etc.) in the embodiments is merely for describing the embodiments in detail, and the scope of the embodiments is limited by the examples or exemplary terms, unless it is defined by the claims. It is not. In addition, those skilled in the art can recognize that various modifications, combinations, and changes can be configured according to design conditions and factors within the scope of the appended claims or equivalents thereof.
