Abstract

A moving image processing device includes a recognition unit, a parameter control unit, and an image processing unit. The recognition unit recognizes a moving object region or a still object region from a captured image. The parameter control unit determines a parameter for image processing of any of a color, a tone, an edge, and a noise. The image processing unit performs image processing to the captured image according to the parameter for the image processing. In this case, the image processing unit performs the image processing to all or a part of the moving object region and all or a part of the still object region, using different parameters.

Claims

1. A moving image processing device comprising:

a recognition unit discriminating a moving object region and a still object region in a moving image composed of a captured image;

a parameter control unit determining a parameter for image processing of at least one of a group including a color, a tone, an edge, and a noise; and

an image processing unit performing the image processing to the captured image according to the parameter, wherein

said image processing unit performs the image processing to at least part of the moving object region and to at least part of the still object region, using different parameters.

2. The moving image processing device according to claim 1, wherein:

said recognition unit recognizes one or more types of still objects from the still object region; and

the image processing unit performs the image processing to the one or more types of still objects, changing the parameter for each of the one or more types of still objects.

3. The moving image processing device according to claim 1, wherein:

said recognition unit determines whether or not a region of a predetermined particular color is the moving object region; and

the image processing unit performs the image processing, using different parameters depending on whether or not the region of the particular color is the moving object region.

4. The moving image processing device according to claim 1, wherein

when the moving object region is a person, the image processing unit allows a skin color of the person to approach to a predetermined memory color.

5. The moving image processing device according to claim 1, further comprising

a parameter input unit inputting the parameters at least for both of the moving object region and the still object region, respectively, wherein

said parameter input unit sets the input parameters to said parameter control unit.

6. A moving image processing method comprising the steps of:

discriminating a moving object region and a still object region in a captured image;

determining a parameter for image processing of at least one of a group including a color, a tone, an edge, and a noise; and

performing the image processing to the captured image according to the parameter, wherein

in the image processing performing step, the image processing is performed to at least part of the moving object region and to at least part of the still object region, using different parameters.

7. The moving image processing method according to claim 6, wherein:

in the discriminating step, one or more types of still objects are recognized from the still object region; and

in the image processing performing step the image processing is performed to the one or more types of still objects, changing the parameter for each of the one or more types of still objects.

8. The moving image processing method according to claim 6, wherein:

in the discriminating step, whether or not a region of a predetermined particular color is the moving object region is determined; and

in the image processing performing step, the image processing is performed, using different parameters depending on whether or not the region of the particular color is the moving object region.

9. The moving image processing method according to claim 6, wherein

in the image processing performing step, when the moving object region is a person, a skin color of the person is allowed to approach to a predetermined memory color.

10. The moving image processing method according to claim 6, further comprising the step of

inputting and setting the parameters at least for both of the moving object region and the still object region, respectively.
