In-vehicle mount type AV system and program
First Claim
1. An in-vehicle mount type AV system which is mounted in a vehicle and comprises a control unit, plural acoustic output units whose acoustic effects are variable, and a display unit, characterized by comprising:
- an angle varying unit for varying an angle of a display face of the display unit; and
an angle detecting unit for detecting the angle varied by the angle varying unit, wherein the control unit controls the acoustic effects of the respective plural acoustic output units on the basis of the varied angle detected by the angle detecting unit.

Abstract
In an in-vehicle mount type AV system for implementing proper acoustic effect control, a swing angle of a rear monitor is detected by a right and left angle sensor, and respective acoustic effects of four speakers (for example, the volume levels of reproduced sounds) are adjusted. The angle detected by the right and left angle sensor corresponds to the angle of the display face of the rear monitor, and the correlation between the display face and the head position of an occupant (automobile passenger) can be estimated. That is, the probability that the head portion of the occupant exists in a direction to which the display face of the rear monitor is oriented is high, and thus the acoustic effect is controlled so that proper volume balance is established at the occupant position thus estimated.

10. A control unit for providing acoustic control of in-vehicle mount type AV system that includes an a display unit having varying angle display capability, the control unit comprising:
-
an angle detecting unit for detecting an angle of display of the display unit, a displacement detecting unit for detecting a displacement of a seat,;
wherein the control unit determines optimum acoustic control based on the displacement detected by the displacement detecting unit based on the varied angle detected by the angle detecting unit.
