Stereo imaging

A method, comprising:

• facilitating digital imaging system for capturing image data, said stereo digital imaging system comprising a first imaging subsystem that comprises a first image sensor arranged to receive light via a first lens and a second imaging subsystem that comprises a second image sensor arranged to receive light via a second lens, wherein said first and second imaging subsystems are arranged such that optical axes of said first and second lenses are in parallel to each other;
• reading pixel values from respective light-sensitive areas of said first and second image sensors, comprising
• reading pixel values for a first image from a first readout area on the first image sensor,
• reading pixel values for a second image from a second readout area on the second image sensor, and
• reading pixel values for support data from at least one portion of the light-sensitive area adjacent to the respective readout area on at least one of the first and second image sensors;
• and
• deriving disparity information pertaining to said first and second images on basis of said pixel values read for the first image, for the second image and for said support data.

A computer program product comprising computer readable program code configured to cause performing, when said program code is run on a computing apparatus, at least the following:

• facilitate digital imaging system for capturing image data, said digital imaging system comprising a first imaging subsystem that comprises a first image sensor arranged to receive light via a first lens and a second imaging subsystem that comprises a second image sensor arranged to receive light via a second lens, wherein said first and second imaging subsystems are arranged such that optical axes of said first and second lenses are in parallel to each other;
• read pixel values from respective light-sensitive areas of said first and second image sensors, comprising
• read pixel values for a first image from a first readout area on the first image sensor,
• read pixel values for a second image from a second readout area on the second image sensor, and
• read pixel values for support data from at least one portion of the light-sensitive area adjacent to the respective readout area on at least one of the first and second image sensors;
• and
• derive disparity information pertaining to said first and second images on basis of said pixel values read for the first image, for the second image and for said support data.

• a memory storing a program of instructions;
• wherein the memory storing the program of instructions is configured to, with the at least one processor, configure the apparatus to at least:
• facilitate stereo image capturing means for capturing image data, said stereo image capturing means comprising a first imaging subsystem that comprises a first image sensor arranged to receive light via a first lens and a second imaging subsystem that comprises a second image sensor arranged to receive light via a second lens, wherein said first and second imaging subsystems are arranged such that the optical axes of said first and second lenses are in parallel to each other;
• read pixel values from respective light-sensitive areas of said first and second image sensors, comprising
• read pixel values for a first image from a first readout area on the first image sensor and
• read pixel values for a second image from a second readout area on the second image sensor, and
• read pixel values for support data from at least one portion of the light-sensitive area adjacent to the respective readout area on at least one of the first and second image sensors;
• and
• derive disparity information pertaining to said first and second images on basis of said pixel values read for the first image, for the second image and for said support data.
