1. A camera comprising:
- a first image collection unit arranged to collect at least a first image comprising a view of at least one body part of a user;
an image processing unit arranged to process the collected first image so as to recognise from the collected first image a position of the at least one body part of the user; and
a control unit arranged to control a field of view of a second image collection unit of the camera to delimit a region of a scene visible to the second image collection unit in dependence upon the recognised position and to exclude a specific object from the field of view of the second image collection unit if the image processing unit recognizes that the user is deliberately occluding the specific object.

Abstract
Method and apparatus for controlling the field of view of a camera are described. The method includes processing at least one collected image so as to calculate at least two positions of at least one body part of a user, and to determine an area defined by said position; and generating a signal suitable for the control of the field of view of a camera in dependence upon said determined area.

10. A control device for controlling a camera comprising:
-
a first image collection unit arranged to collect at least a first image comprising a view of at least one body part of a user; an image processing unit arranged to process the collected first image so as to recognise from the collected first image a position of the at least one body part of the user; and a control unit arranged to control a field of view of a second image collection unit of the camera to delimit a region of a scene visible to the second image collection unit in dependence upon the recognised position wherein the control unit is arranged to control the second image collection unit to align a border of the delimited region with a specific object within the field of view of the second image collection unit if the image processing unit recognises the specific object as a framing object and wherein the control unit is arranged to control the second image collection unit to exclude the framing object from the delimited region.

14. A control device for controlling a camera comprising:
-
a first image collection unit arranged to collect at least a first image comprising a view of at least one body part of a user; an image processing unit arranged to process the collected first image so as to recognise from the collected first image a position of the at least one body part of the user; and a control unit arranged to control a field of view of a second image collection unit of the camera to delimit a region of a scene visible to the second image collection unit in dependence upon the recognised position wherein the image processing unit is arranged to compensate for parallax between the first image collection unit and a viewpoint of the user, so as to determine an area defined by the positions as viewed from the perspective of the user wherein a pair of viewpoints, each located at a respective eye of the user are assumed and a desired field of view of the second image collection unit is calculated based upon the field of view visible from each eye as delimited by recognised hand gestures of the user.

15. A control device for controlling a camera comprising:
-
a first image collection unit arranged to collect at least a first image comprising a view of at least one body part of a user; an image processing unit arranged to process the collected first image so as to recognise from the collected first image a position of the at least one body part of the user; and a control unit arranged to control a field of view of a second image collection unit of the camera to delimit a region of a scene visible to the second image collection unit in dependence upon the recognised position wherein the image processing unit is arranged to compensate for parallax between the first image collection unit and a viewpoint of the user, so as to determine an area defined by the positions as viewed from the perspective of the user wherein a pair of viewpoints, each located at a respective eye of the user are assumed and a plurality of second image collection units are provided, the plurality of second image collection units being arranged to capture a totality of the possible field of view of the user as viewed from each eye and delimited by gestures of the user.

29. A control device for controlling a camera, the device comprising:
-
a first image collection unit arranged to collect at least a first image comprising a view of at least one body part of a user; and an image processing unit arranged to process the collected first image so as to recognise from the collected first image a position of the at least one body part of the user; and a signal generation unit arranged to generate a signal suitable for control of a field of view of a second image collection unit of the camera to delimit a region of a scene visible to the first image collection unit in dependence upon the recognised position and to exclude a specific object from the field of view of the second image collection unit if the image processing unit recognizes that the user is deliberately occluding the specific object. - View Dependent Claims (30)

31. A method of controlling a field of view of a camera, the method comprising:
-
processing a collected first image comprising a view of at least one body part of a user to calculate from the collected first image a position of the at least one body part of the user; and controlling the field of view of an image collection unit of the camera to delimit a region of a scene visible to the camera image collection unit in dependence upon the calculated position and to exclude a specific object from the field of view of the image collection unit if the image processing unit recognizes that the user is deliberately occluding the specific object. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39)
