Three cases are assumed in which the display is focused and stopped. Such three cases can be discriminated by analyzing the direction of the line of sight by analyzing the camera output on the apparatus side, for example.

  First, considering the first case of passing without paying attention to the display, in this case, only the front is passed. For example, in the morning, the sound is reduced by lowering the volume, or from the sound data in advance. It is possible to classify quiet melody, noisy melody, fun melody, sad melody, etc., and compose musical sounds by combining melody corresponding to adjectives or adjectives such as quiet and calm.

  Considering the second case of passing while paying attention to the display, in this case, the volume is increased during the daytime, and a pop and bright melody is collected to attract more attention. It is possible to compose a musical tone by selecting and combining them.

  Considering the third case where attention is paid to the display and stops, in this case, the volume is medium, and it matches the image of the displayed contents of the display display, and selects adjectives and adjectives so as not to damage the contents. It is possible to compose a musical sound by combining melody with the correspondence.

  Furthermore, as an example of constructing musical sound content using such a device, there are cases where there is only one person in front of the display display, there are several persons, and there are many people in the group. It is done.

  First, when there is only one person, by reflecting attribute information based on various attributes such as personal hobbies and preferences recorded in an ID tag carried by the target person acquired through the environmental information acquisition unit 14 It is possible to compose a musical tone close to the personal preference.

  In addition, when there are a plurality of persons, a necessary number of personal information acquired through the environment information acquisition unit 14 is selected, and the attribute information is randomly rearranged to compose a musical tone including a new image different from when alone. It is possible.

  If you are a group that forms a group, for example, it reflects the time of the day, and in the morning it constitutes a musical sound that reflects adjectives and adjectives such as `` healing and quiet '' symbolized by healing. , Composed of adjectives and adjectives such as “Energetic and Bright” in the active image at noon, and composed of adjectives and adjectives such as “adult and calm” at night Is possible.

  In this case, it is also possible to select adjectives or adjectives that match the characteristics of the station (passage / station premises), stores (restaurants, jewelry stores, clothing stores, etc.), and various locations, taking into account the installation location. .

Keen; “Want to be warm, varied, natural, want to pinch”
Time: “Light, new, fast, old, slow”
The factor score is calculated by performing factor analysis, thereby creating the score table shown in FIG. 8, and from the score higher than the reference score predetermined in this score table (for example, bold portion in FIG. 8) Deriving factors. FIG. 8 shows the case of two factors. The obtained numerical value of the factor score is passed to the parameter extraction unit 15 shown in FIGS. 1 and 3, and is substituted for the coefficient k _ij corresponding to the factor (n, m, d,...) Corresponding to each factor score. Thus, the parameters P _f , P _c , and P _t are calculated in the equations (Equation 2), (Equation 3), and (Equation 4).

The parameter control unit 16 shown in FIGS. 1 and 3 controls the parameters of the volume equalizer unit 12 based on the parameters obtained from the parameter extraction unit 15.
FIG. 9 shows the flow of processing in the tone source selection unit 21 shown in FIGS. When the environment information acquisition unit 14 exists (S200 “YES”), the environment information is acquired from the environment information acquisition unit 14 illustrated in FIGS. 1 to 3 (S202). Further, when the environment information acquisition unit 14 does not exist (S200 “NO”), this corresponds to the case of (S101 “NO”) in FIG. 7, but in this case, although not shown, a built-in random number generation unit A random number is generated, and this random value is set as a temporary environment information value (S201). Next, a musical sound source selection determination process is performed using the threshold value Th for determining “YES” or “NO” set in advance in the value acquired in the process step S201 or the process step S202 (S203). That is, the musical sound source selection determination process compares the magnitude relationship between the random number value and a preset threshold value. Here, if the initially set random number value does not fall within a predetermined range with respect to the threshold value Th, the processing step “Generate random number value (S201)” to “musical sound source selection” until “YES” is obtained. The steps up to the “determination process (S203)” are repeated. In response to this result when it falls within the range with respect to the threshold Th, the musical sound source reading unit 11 selects a plurality of corresponding arbitrary musical sound sources (S204).

  2 and 3 mixes a plurality of tone sources selected by the tone source selection unit 21 and passes them to the sound source output unit 13.
