Abstract

An image pickup apparatus having a function of performing cut-out processing for an image for electronic image-stabilization and detecting a particular object of the image is provided. The image pickup apparatus detects a particular object from an image that has not been subjected to cut-out processing for electronic image-stabilization, adjusts position information of the detected object in accordance with a cut-out position of the image for electronic image-stabilization, and combining an indication indicating the position of the particular object with a display image based on positional information after the adjustment is performed.

Claims

1. An image processing apparatus comprising:

an image stabilization control unit configured to detect an image shake component generated in a shooting operation, and to set a cut-out position of an image so as to cancel out the image shake component;

a generation unit configured to perform cut-out processing using the cut-out position and resize processing for the image to generate a display image;

a detection unit configured to detect an area of the image that has not been subjected to the cut-out processing and resize processing by the generation unit, the area containing a human being, and to generate information on a position of the detected area;

an adjusting unit configured to adjust the information on the position of the detected area in accordance with the cut-out position and a magnification of the resize processing; and

a display unit configured to display an indication indicating a position of the human being with the display image, based on the information on the position of the detected area after the adjustment is performed.

2. The image processing apparatus according to claim 1,

wherein the image stabilization control unit set the cut-out position in accordance with a motion vector detected from the image.

3. The image processing apparatus according to claim 1, further comprising an image pickup element,

wherein the image stabilization control unit includes a gyroscope configured to detect an acceleration of movement of the image processing apparatus.

4. The image processing apparatus according to claim 1, further comprising an image pickup element,

wherein at least one of automatic focus control and exposure control is performed by using the information on the position of the area detected by the detection unit.

5. A method for image processing, the method comprising:

detecting an image shake component generated in a shooting operation, and setting a cut-out position of an image so as to cancel out the image shake component;

performing cut-out processing using the cut-out position and resize processing for the image to generate a display image;

detecting an area of the image that has not been subjected to the cut-out processing and resize processing, the area containing a human being, and generating information on a position of the detected area;

adjusting the information on the position of the detected area in accordance with the cut-out position and a magnification of the resize processing; and

displaying an indication indicating a position of the human being with the display image, based on the information on the position of the detected area after the adjustment is performed.
