Video signal processing device and video signal processing method

Summary of Embodiment 1

[0096]Examples of advantageous effects of the present embodiment are as follows.

[0097]According to a conventional technique, if a superimposed signal is stereo-converted, superimposed additional information such as OSD is also stereo-converted, and the display position of the additional information also shifts. Accordingly, although there has been an attempt to avoid quality correction only on the display area of the additional information, selectively, it results in a failure.

[0098]In contrast, according to the present invention, the stereo conversion unit 2 also corrects first locating signals indicating the position of additional information such as OSD, in accordance with stereo conversion processing on two-dimensional video signals, thereby generating second locating signals as new position information.

[0099]The video signal processing device 1 according to the present embodiment can locate, by using such second locating signals, the position of additional i

Summary of Embodiment 2

[0144]Examples of advantageous effects of the present embodiment are as follows.

[0145]First, the present embodiment has an effect of not performing quality correction on an area in which additional information such as OSD is displayed, as with Embodiment 1. Thus, the present embodiment brings an advantage of not giving a viewer a sense of unnaturalness, and the advantage leads to a great effect in light of health and mind, in addition to improvement in the quality of a video outputted from the video signal processing device 10 as a whole, as well as in Embodiment 1.

[0146]Furthermore, an example of a feature of the video signal processing device 10 according to the present embodiment is that the additional information such as OSD is not stereo-converted. It is possible to give a viewer various visual effects by stereo-converting additional information such as OSD. However, it is often difficult to set an appropriate value indicating how much depth is to be given w
