Abstract
An image processing apparatus obtains a difference between a partial region of an input image and a partial region of a background image, stored in a storage device, corresponding to the partial region of the input image, determines whether each partial region of the input image is a moving body region or a background region based on the difference, and combines the partial region of the input image determined as the background region and the partial region of the background image corresponding to the partial region of the input image to update the background image.
Claims10
An image processing apparatus comprising:
- an image input unit configured to input an image;
- a region determination unit configured to obtain a difference between a partial region of an input image input by the image input unit and a partial region of a background image, stored in a storage device, corresponding to the partial region of the input image and to determine whether each partial region of the input image is a moving body region or a background region based on the difference;
- and
- a synthesizing unit configured to synthesize the partial region of the input image determined as the background region by the region determination unit and the partial region of the background image corresponding to the background region of the input image by calculating respective pixel values of corresponding regions;
- and
- an updating unit configured to update a partial region the background image corresponding to the background region of the input image by the synthesized image for the background region.
An image processing method performed by using a processor, the method comprising:
- inputting an image;
- obtaining a difference between a partial region of an input image and a partial region of a background image, stored in a storage device, corresponding to the partial region of the input image and determining whether each partial region of the input image is a moving body region or a background region based on the difference;
- and
- synthesizing the partial region of the input image determined as the background region and the partial region of the background image corresponding to the background region of the input image by calculating respective pixel values of corresponding regions;
- and
- updating a partial region of the background image corresponding to the background region of the input image by the synthesized image for the background region.
