Abstract: Various embodiments relate to systems and methods for controlling one or more LED-based lighting sources that are coupled to a logic module by a ribbon cable. The ribbon cable allows some or all of the processing components (e.g., processors and drivers) to be decoupled from the LED-based lighting source(s). The processing components can instead be housed within the logic module, which is able to simultaneously control the LED-based lighting source(s). Together with color models established for each LED board, the logic module acts as a platform for modularity and is able to more precisely control the color channels of each LED-based lighting source using the color models established for those LED-based lighting source(s). Techniques are also described herein that allow the logic module to utilize data stored within an erasable programmable read-only memory (EPROM) that describes the color characteristics of an LED-based lighting source.

Abstract: Introduced here are computer programs and associated computer-implemented techniques for determining reflectance of an image on a per-pixel basis. More specifically, a characterization module can initially acquire a first data set generated by a multi-channel light source and a second data set generated by a multi-channel image sensor. The first data set may specify the illuminance of each color channel of the multi-channel light source (which is configured to produce a flash), while the second data set may specify the response of each sensor channel of the multi-channel image sensor (which is configured to capture an image in conjunction with the flash). Thus, the characterization module may determine reflectance based on illuminance and sensor response. The characterization module may also be configured to determine illuminance based on reflectance and sensor response, or determine sensor response based on illuminance and reflectance.

Abstract: Introduced here are light sources for flash photography configured to produce high-fidelity white light that is tunable over a broader range of correlated color temperatures (CCTs) than conventional flash technologies. The light source can include multiple independently controllable color channels representing illuminants (e.g., light-emitting diodes) of different colors with varying degrees of saturation. Operating collectively, the multiple color channels can produce a high spectral quality white light corresponding to different CCTs (e.g., “warm” white light having a red hue, “cool” white light having a blue hue). Operating independently, these same color channels can be pre-flashed in a variety of prescribed sequences to probe the spectral characteristics of a scene, thereby allowing for an enhanced, spectrally matched white flash as well as collecting per-pixel reflectivity data that can be later used in during post processing of the captured image.

Abstract: A steering assembly includes a movable anchor. Movement of the anchor in a first direction is restricted. A first linkage is coupled to the anchor and a second linkage it rotatably coupled to the first linkage. The second linkage is configured to couple to a contactor. A drive mechanism moves the second linkage relative to the first linkage. At least one of moving the second linkage and moving the anchor maneuvers the contactor to a desired position.

Abstract: Introduced here are techniques for generating color mixing models that enable a tunable lamp to mix the right amount of light from various color channels in order to properly produce colors. More specifically, a lamp controller can be configured to drive multiple light-emitting diode (LED) arrays based on corresponding color mixing models. One or more color mixing models can be provisioned into the memory of an LED array prior to usage. Storing the color mixing model in the LED array enables the lamp controller to update the color mixing model based on which LED array it is serving (i.e., the lamp controller and the LED array need not be a permanently matched set). Additionally or alternatively, the lamp controller may be configured to communicate with a network-accessible computer server system to access a historical color mixing database that includes set(s) of previously-recorded spectral properties and corresponding color mixing models.
