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 and determining whether or not a subject of the moving object region is a person;

a parameter control unit determining a combination of parameters for each image processing, the parameters being a color, a tone, and an edge; and

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

the parameter control unit changes a combination of the parameters to be performed on at least part of the moving object region from a combination of the parameters to be performed on at least part of the still object region, and changes the combination of the parameters to be performed on the still object region depending on a determination result of whether or not the moving object region is the person.

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

the 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 parameters for each of the one or more types of still objects.

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

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

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

when the moving object region is the person, the image processing unit:

sets tone characteristics to provide a soft tone and performs weak edge enhancement for the moving object region; and

performs color correction to provide high chroma, sets the tone characteristics to provide a hard tone and performs strong edge enhancement for the still image region.

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

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

the parameter input unit sets the input parameters to the 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 whether or not a subject of the moving object is a person;

determining a combination of parameters for each image processing, the parameters being a color, a tone, and an edge; and

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

the parameters determining step changes a combination of the parameters to be performed on at least part of the moving object region from a combination of the parameters to be performed on at least part of the still object region, and changes the combination of the parameters to be performed on the still object region depending on a determination result of whether or not the moving object region is the person.

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 parameters for each of the one or more types of still objects.

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

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

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

when the moving object region is the person, the image processing performing step:

sets tone characteristics to provide a soft tone and performs weak edge enhancement for the moving object region; and

performs color correction to provide high chroma, sets the tone characteristics to provide a hard tone and performs strong edge enhancement for the still image region.

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

inputting and setting the parameters at least for the moving object region and the still object region.
