Abstract

A video processing apparatus includes a property change acquisition unit for acquiring a change of a property of an input video, a video processing unit for performing video processing on the input video, a gain adjustment unit for adjusting a gain for the video processing, and a control unit for performing control to change a setting for the video processing in the video processing unit according to the property change of the input video and decrease a gain of the gain adjustment unit at a timing of changing the setting for the video processing.

Claims

1. A video processing apparatus comprising:

a property change acquisition unit for acquiring a change of a property of an input video;

a video processing unit for performing video processing on the input video;

a gain adjustment unit for adjusting a gain for the video processing; and

a control unit for performing control to change a setting for the video processing in the video processing unit according to the property change of the input video and decrease a gain of the gain adjustment unit at a timing of changing the setting for the video processing.

2. The video processing apparatus according to claim 1, wherein the control unit sets the gain of the gain adjustment unit to 0 at the timing of changing the setting for the video processing to make the video processing in the video processing unit inactive.

3. The video processing apparatus according to claim 2, wherein the control unit sets the gain of the gain adjustment unit to 0 during a predetermined period of time including the timing of changing the setting for the video processing to make the video processing in the video processing unit inactive.

4. The video processing apparatus according to claim 3, wherein the control unit decreases the gain of the gain adjustment unit to 0 before the predetermined period of time and increases the gain of the gain adjustment unit after the predetermined period of time elapses.

5. The video processing apparatus according to claim 1, wherein the control unit changes the setting of the video processing in the video processing unit in stages according to the property change of the input video.

6. A video processing method comprising:

acquiring a change of a property of an input video;

performing video processing on the input video;

changing a setting for the video processing according to the property change of the input video; and

decreasing a gain for the video processing at a timing of changing the setting for the video processing.

7. The video processing method according to claim 6, wherein the decreasing of the gain for the video processing includes decreasing the gain to 0 to make the video processing inactive.

8. The video processing method according to claim 7, wherein the decreasing of the gain for the video processing includes setting the gain for the video processing to 0 during a predetermined period of time including the timing of changing the setting for the video processing.

9. The video processing method according to claim 8, wherein the decreasing of the gain for the video processing includes decreasing the gain to 0 before the predetermined period of time and increasing the gain after the predetermined period of time elapses.

10. The video processing method according to claim 6, wherein the changing of the setting for the video processing includes changing the setting for the video processing in stages according to the property change of the input video.
