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:

a generation unit configured to perform cut-out processing for an 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 by the generation unit, the area containing an object satisfying a set condition, and to generate information on a position of the detected area; and

a combining unit configured to adjust the information on the position of the detected area in accordance with a cut-out position of the image where the cut-out processing is performed by the generation unit, and to combine an indication indicating a position of the object 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 generation unit generates the display image by performing the cut-out processing for the image and then performing resize processing of the processed image, and

wherein the combining unit adjusts the information on the position of the detected area in accordance with the cut-out position of the image where the cut-out processing is performed by the generation unit and a magnification of the resize processing.

3. The image processing apparatus according to claim 1,

wherein the generation unit performs the cut-out processing in accordance with a motion vector detected from the image.

4. The image processing apparatus according to claim 1, further comprising:

an image pickup element; and

a shake detection unit configured to detect a shake of the image processing apparatus,

wherein the generation unit generates, in accordance with a detection result obtained by the shake detection unit, the display image from an image obtained from the image pickup element.

5. The image processing apparatus according to claim 4,

wherein the shake detection unit detects the shake of the image processing apparatus by detecting a motion vector from the image obtained from the image pickup element.

6. The image processing apparatus according to claim 4,

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

7. The image processing apparatus according to claim 4,

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.

8. An image pickup apparatus comprising:

an image pickup element;

a shake detection unit configured to detect a shake;

a generation unit configured to perform cut-out processing for an image in accordance with a detection result obtained by the shake detection unit 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 by the generation unit, the area containing an object satisfying a set condition, and to generate information on a position of the detected area;

an image pickup control unit configured to perform at least one of automatic focus control and exposure control by using the information on the position of the area detected by the detection unit; and

a combining unit configured to adjust the information on the position of the detected area in accordance with a cut-out position of the image where the cut-out processing is performed by the generation unit, and to combine an indication indicating a position of the object with the display image based on the information on the position of the detected area after the adjustment is performed.

9. The image pickup apparatus according to claim 8,

wherein the generation unit generates the display image by performing the cut-out processing for the image and then performing resize processing of the processed image, and

wherein the combining unit adjusts the information on the position of the detected area in accordance with the cut-out position of the image where the cut-out processing is performed by the generation unit and a magnification of the resize processing.

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

performing cut-out processing for an image to generate a display image;

detecting an area of the image that has not been subjected to the cut-out processing, the area containing an object satisfying a set condition, and generating information on a position of the detected area; and

adjusting the information on the position of the detected area in accordance with a cut-out position of the image, and combining an indication indicating a position of the object with the display image based on the information on the position of the detected area after the adjustment is performed.

11. The method according to claim 10,

wherein the display image is generated by performing the cut-out processing for the image and then performing resize processing of the processed image, and

wherein the information on the position of the detected area is adjusted in accordance with the cut-out position of the image and a magnification of the resize processing.
