PROBLEM TO BE SOLVED: To provide a device and a method for adjusting a video signal, which smoothly scrolls a character even when the scroll speed of the character for the video signal containing a scroll character is not constant. SOLUTION: The device 11 for adjusting the video-signal composed of a character-region detecting section 111, a memory 12 for recording a video, and a video adjusting section 113, is fitted between a video output terminal 10 and a signal converter 12. The character-region detecting section 111 divides the scroll character into a graphic and the scroll character and writes the graphic and the scroll character to the memory 112 for recording the video while inputting a character detecting signal Sgd and coordinates Smv to the video adjusting section 113 when the scroll character is contained in the video signal Sgs from the video output terminal 10. The video adjusting section 113 reads the combination of the graphic keeping the movement of the scroll character constant and the scroll character from the memory 112 for recording the video in response to the result of the detection of the scroll character and the coordinates Smv, and inputs these combination to the signal converter 12 as an adjusted video signal Sgadj.
