Spatially adjustable flash for imaging devices

A spatial flash exposure adjustment system comprising:

• a flash filter panel comprising a plurality of transparency adjustable regions, wherein the flash filter panel is configured to be mounted adjacent to a flash module;
• and
• a controller coupled to the flash filter panel, the controller to adjust transparencies of the transparency adjustable regions of the flash filter panel based on flash filter panel control parameters and to operate by:
• obtaining the image data during a pre-flash exposure of the scene,
• determining a first brightness of a first subject of the scene and a second brightness of a second subject of the scene based on the image data, wherein the first subject of the scene is associated with the region of the flash filter panel and the second subject of the scene is associated with a second region of the flash filter panel, and
• generating a transparency parameter for the region of the flash filter panel based on the first brightness and the second brightness, wherein the transparency parameter comprises a ratio of the second brightness to the first brightness.

At least one non-transitory machine readable medium comprising a plurality of instructions that in response to being executed on an imaging device, cause the imaging device to spatially adjust flash exposures by:

• determining flash filter panel control parameters based on image data associated with a scene and comprising:
• obtaining the image data during a pre-flash exposure of the scene,
• determining a first brightness of a first subject of the scene and a second brightness of a second subject of the scene based on the image data, wherein the first subject of the scene is associated with the region of the flash filter panel and the second subject of the scene is associated with a second region of the flash filter panel, and
• generating a transparency parameter for the region of the flash filter panel based on the first brightness and the second brightness, wherein the transparency parameter comprises a ratio of the second brightness to the first brightness;
• adjusting a transparency of a region of a flash filter panel adjacent to a flash module of the imaging device based on the flash filter panel control parameters;
• and
• exposing the scene by providing a flash light from the flash module and through the flash filter panel to generate captured image data.
