Light field collection control methods and apparatuses, light field collection devices

A light field collection control apparatus, comprising:

• a main lens aperture parameter acquisition module, configured to acquire an aperture parameter of a main lens of a light field camera;
• a first imaging region determination module, configured to determine, according to the main lens aperture parameter, in an image sensor of the light field camera, a local part of an imaging region corresponding to at least one sub-lens in a sub-lens array of the light field camera as a first imaging region;
• a pixel density distribution adjustment module, configured to adjust pixel density distribution of the image sensor, to cause pixel density of the first imaging region after adjustment to be distinguished from that of other parts of the imaging region;
• and
• a light field collection control module, configured to perform light field collection on a scene via the adjusted light field camera.

A non-transitory computer-readable medium comprising a set of executable instructions, which, in response to execution, cause one or more processors to perform the operations, comprising:

• acquiring an aperture parameter of a main lens of a light field camera;
• determining, according to the main lens aperture parameter, in an image sensor of the light field camera, a local part of an imaging region corresponding to at least one sub-lens in a sub-lens array of the light field camera as a first imaging region;
• adjusting pixel density distribution of the image sensor, to cause pixel density of the first imaging region after adjustment to be distinguished from that of other parts of the imaging region;
• and
• performing light field collection on a scene via the adjusted light field camera.

A light field collection control apparatus, characterized by comprising a processor and a memory, the memory storing computer executable instructions that, in response to execution, cause the apparatus to perform operations, comprising:

• acquiring an aperture parameter of a main lens of a light field camera;
• determining, according to the main lens aperture parameter, in an image sensor of the light field camera, a local part of an imaging region corresponding to at least one sub-lens in a sub-lens array of the light field camera as a first imaging region;
• adjusting pixel density distribution of the image sensor, to cause pixel density of the first imaging region after adjustment to be distinguished from that of other parts of the imaging region;
• and
• performing light field collection on a scene via the adjusted light field camera.
