Abstract
Arrangement for acquiring images for producing a head related transfer function filter is disclosed. In the arrangement the camera of a mobile phone or similar portable device is adjusted for the imaging. All acquired images are analyzed and only suitable images are sent further for producing the head related transfer filter. The arrangement is further configured to provide instructions to the user so that the whole head and other relevant body parts are sufficiently covered.
Claims28
A method for acquiring images required for determining head related transfer function filters, the method comprising:
- capturing, using a range imaging device of a user device, a plurality of images;
- providing, using a haptic device in the user device, haptic feedback to the user while the range imaging device is capturing the plurality of images;
- receiving the plurality of images from the range imaging device;
- determining whether at least one image comprises sufficient anatomy in order to produce a head related transfer function filter;
- and
- if it is determined that the at least one image does not comprise sufficient anatomy capturing, using the range imaging device, one or more additional images of areas that are not sufficiently covered in the at least one image.
A method for acquiring images required for producing geometrical data for head related transfer function filters, the method comprising:
- responsive to user input to generate a heard-related transfer function, capturing, using a range imaging device in a user device, a plurality of images;
- selecting a subset of images from the plurality of images showing anatomy of an ear;
- determining if the selected subset comprises sufficient anatomy in order to produce the head related transfer function filter;
- responsive to determining that the selected subset does not comprise sufficient anatomy in order to produce the head related transfer function filter, presenting notification to acquire additional images of areas that are not sufficiently covered in the selected subset;
- and
- capturing, using the range imaging device in the user device, the additional images of areas that are not sufficiently covered in the selected subset responsive to user input to acquire the additional images.
An electronic device comprising:
- a range imaging device;
- a haptic device;
- at least one processor;
- and
- memory having instructions which when executed by the at least one processor causes the electronic device to:
- capture, using the range imaging device, a plurality of images,
- provide, using the haptic device, haptic feedback while the range imaging device is capturing the plurality of images,
- determine whether at least one image includes sufficient anatomy in order to produce a head related transfer function filter, and
- responsive to the at least one image not including sufficient anatomy, capture, using the range imaging device, one or more additional images of one or more areas that are not sufficiently covered in the at least one image.
A method comprising:
- capturing, using a range imaging device of a user device, a plurality of images;
- providing, using a haptic device in the user device, haptic feedback to the user while the range imaging device is capturing the plurality of images;
- determining whether at least one image of the plurality of images comprises sufficient anatomy in order to produce a head related transfer function filter;
- and
- if it is determined that the at least one image does not comprise sufficient anatomy, providing, using a speaker of the user device, audio feedback indicating for the user to capture, using the range imaging device, one or more additional images of areas that are not sufficiently covered in the at least one image.
