| description | There is provided a signal processing device capable of changing a resolution of a synthesized image signal without bleeding in an image of a first image signal (a character signal) contained in the synthesized image signal, and an image output device capable of outputting and simultaneously displaying the synthesized image signals having a plurality of resolutions to and in a plurality of display devices. In a case of changing the resolution of the synthesized image signal obtained by synthesizing the first image signal and a second image signal, identification information for identifying whether or not the character signal is contained is added to the synthesized image signal based on presence/absence of the character signal, by a character signal creating unit 12 and a character signal synthesizing unit 13. Then, based on the identification information, a resolution changing unit 14 separates the synthesized image signal into a third image signal containing a component of the character signal and a fourth image signal containing no component of the character signal, changes the resolutions of the third image signal and the fourth image signal, and synthesizes the third image signal and the fourth image signal with the resolutions changed, based on the identification information. |
