Abstract
An image processing apparatus and method wherein image data is input and separated into foreground object data and background object data, image data in a missing portion of the background object data formed by a separation of the foreground object data is interpolated by using image data around the missing portion.
Claims21
An image processing apparatus comprising:
- a) an input unit, arranged to input background object data, wherein the background object data is image data in a picture which remains after removing foreground object data from the picture, the removal producing a missing portion in the picture corresponding to the removed foreground object data;
- and
- b) an interpolating unit, arranged to generate background object data of the missing portion corresponding to the foreground object data using background object data of another picture, and to interpolate the missing portion of the input picture with the generated background object data.
An image processing apparatus comprising:
- a) an input unit, arranged to input image data of a picture;
- b) a separating unit, arranged to separate the image data input by said input unit into foreground object data and background object data;
- c) an interpolating unit, arranged to generate background object data of the missing portion corresponding to the separated foreground object data using background object data of another picture, and to interpolate the missing portion of the picture with the generated background object data;
- d) a first encoding unit, arranged to encode the picture interpolated by said interpolating unit;
- and
- e) a second encoding unit, arranged to encode the foreground object data.

An image processing method comprising the steps of:
- a) inputting background object data, wherein the background object data is image data in a picture which remains after removing foreground object data from the picture, the removal producing a missing portion in the picture corresponding to the removed foreground object data;
- and
- b) generating interpolated background object data of the missing portion corresponding to the foreground object data using background object data of another picture, and interpolating the missing portion of the input picture with the generated background object data.
