Abstract

This invention provides an image processing apparatus/method characterized by inputting image data, detecting an object in the input image data, measuring the distance from the detected object to a predetermined position, and detecting a predetermined object on the basis of the measurement result.

This invention also provides an image processing apparatus/method characterized by inputting image data by image pickup means having an optical system, detecting an object in the input image data, controlling the optical system of the image pickup means, and detecting a predetermined object on the basis of the object detection result and the optical system control result.

Claims

1. An image processing apparatus comprising:

a) input means for inputting image data;

b) object detecting means for detecting an object in the input image data from said input means;

c) measuring means for measuring a distance from the object detected by said object detecting means to a predetermined position; and

d) predetermined object detecting means for detecting a predetermined object on the basis of an output from said measuring means.

2. An apparatus according to claim 1, wherein said predetermined object detecting means detects an object whose distance to the predetermined position falls within a predetermined range.

3. An apparatus according to claim 2, wherein said input means comprises image pickup means for picking up an image of an object via an optical system.

4. An apparatus according to claim 3, wherein the predetermined position is a position of said image pickup means.

5. An apparatus according to claim 3, wherein

said image pickup means comprises focusing control means for controlling focusing of said optical system, and

wherein said measuring means measures the distance from the object detected by said object detecting means to the predetermined position on the basis of focusing control information from said focusing control means.

6. An apparatus according to claim 1, further comprising size detecting means for detecting a size of the object detected by said object detecting means,

wherein said predetermined object detecting means detects an object with a predetermined size on the basis of an output from said size detecting means.

7. An apparatus according to claim 6, wherein said predetermined object detecting means comprises setting means for setting a size of an object to be detected.

8. An apparatus according to claim 6, wherein

said input means comprises image pickup means for picking up an image of an object via an optical system,

said image pickup means comprising zoom control means for controlling said optical system to enlarge an image, and

wherein said predetermined object detecting means detects an object with the predetermined size on the basis of zoom control information from said zoom control means.

9. An apparatus according to claim 8, wherein

said image pickup means comprises focusing control means for controlling focusing of said optical system, and

wherein said measuring means measures the distance from the object detected by said object detecting means to the predetermined position on the basis of focusing control information from said focusing control means.

10. An apparatus according to claim 1, further comprising output means for outputting a detection output from said predetermined object detecting means to an external apparatus.

11. An apparatus according to claim 10, wherein when said predetermined object detecting means detects a predetermined object, said output means outputs the detection result to said external apparatus.
