Abstract

An image processing apparatus includes an acquisition unit configured to acquire a captured image selected according to specified viewpoint information from a plurality of captured images captured by a plurality of imaging units at different viewpoint positions, a generation unit configured to generate an image according to the specified viewpoint information using the viewpoint information of the selected captured image and the specified viewpoint information from the selected captured image, and a blurring processing unit configured to execute blurring processing on the generated image, wherein, when an imaging unit corresponding to a captured image for a target frame is different from an imaging unit corresponding to a captured image for a frame adjacent to the target frame, the blurring processing unit executes blurring processing on the generated image corresponding to the target frame.

Claims

1. An image processing apparatus, comprising:

an acquisition unit configured to acquire a captured image selected according to specified viewpoint information from a plurality of captured images captured by a plurality of imaging units at different viewpoint positions;

a generation unit configured to generate an image according to the specified viewpoint information using the viewpoint information of the selected captured image and the specified viewpoint information from the selected captured image; and

a blurring processing unit configured to execute blurring processing on the generated image,

wherein, when an imaging unit corresponding to a captured image for a target frame is different from an imaging unit corresponding to a captured image for a frame adjacent to the target frame, the blurring processing unit executes blurring processing on the generated image corresponding to the target frame.

2. The image processing apparatus according to claim 1, wherein the generation unit generates an image corresponding to the specified viewpoint information from the selected captured image by associating pixels of the selected captured image with pixels of the captured image corresponding to the specified viewpoint information through a reference plane defined by reference plane information based on the viewpoint information of the selected captured image, the specified viewpoint information, and the reference plane information.

3. The image processing apparatus according to claim 1, wherein the blurring processing unit calculates a motion vector of a point-of-interest between the target frame and the adjacent frame of the target frame, and controls a direction and degree of blurring processing to be executed according to the motion vector.

4. The image processing apparatus according to claim 1, wherein the blurring processing unit does not execute blurring processing on the generated image corresponding to the target frame when the imaging unit corresponding to the image for the target frame is identical to the imaging unit corresponding to the captured image for the frame adjacent to the target frame.

5. The image processing apparatus according to claim 1, further comprising a sharpness processing unit configured to execute sharpness processing on the generated image,

wherein the sharpness processing unit does not execute sharpness processing on the generated image on which the blurring processing unit executed the blurring processing.

6. An image processing method, comprising:

acquiring a captured image selected according to specified viewpoint information from a plurality of captured images captured by a plurality of imaging units at different viewpoint positions;

generating an image according to the specified viewpoint information using the viewpoint information of the selected captured image and the specified viewpoint information from the selected captured image; and

executing blurring processing on the generated image,

wherein the blurring processing is executed on the generated image corresponding to the target frame when an imaging unit corresponding to a captured image for a target frame is different from an imaging unit corresponding to a captured image for a frame adjacent to the target frame.

7. A non-transitory computer-readable storage medium storing a computer program which is read and executed by a computer to cause the computer to execute the processing defined in claim 6.
