Abstract: An apparatus includes a light modulator configured to modulate light to display frames of images based on display image data, and a controller coupled to the light modulator. The controller is configured to obtain a sequence of image data to be displayed by the light modulator; produce the display image data based on the sequence of image data; transmit the display image data to the light modulator; determine, based on the sequence of image data, to enter one or more sleep modes that reduce power usage by the controller, the light modulator, or an interface between the controller and the light modulator compared to a normal operation mode; and enter one or more extended sleep modes that have lower power usage than the one or more sleep modes if an extended sleep mode signal is detected in the sequence of image data.

Abstract: A method includes receiving, by a frame converter, a frame of pixel data and converting, by the frame converter, the frame to a first frame division unit. The method also includes receiving, by a translation circuit, a pixel coordinate and cropping and shifting, by the translation circuit, the first frame division unit based on the pixel coordinate, to produce a second frame division unit. Additionally, the method includes outputting, by the translation circuit, the second frame division unit.

Abstract: In some examples, a method includes serializing, via a processor, image data for a first image to form serialized data mapped to RBG pixels of a second image, the image data in a format other than a RGB pixel format. The method also includes transmitting, by the processor, the serialized data via RGB signaling lines.

Abstract: A method includes converting a frame of pixel data to a first frame division unit. The method further includes, responsive to an X,Y coordinate, cropping and shifting the frame division unit to produce a second frame division unit. The method also includes outputting the second frame division unit.

Abstract: A depth imaging system includes an optical image sensor, an optical beam steering system, an object identification system, and a depth measurement system. The object identification system is coupled to the optical image sensor. The object identification system is configured to identify an object in an image captured by the optical image sensor. The depth measurement system is coupled to the optical beam steering device. The depth measurement system is configured to, responsive to identification of the object by the object identification system: direct an optical signal, via the optical beam steering device, to the object, and to determine a distance to the object based on a time-of-flight of the optical signal.

Abstract: In described examples, a circuit for controlling a light emitting diode (LED) includes a first flip flop including first and second control inputs. In response to assertion of a first control signal, the first flip flop generates a second control signal to control a first switch coupled in parallel with the LED. An edge detect circuit is coupled to an output of the first flip flop. In response to generation of the second control signal, the edge detect circuit generates a third control signal. A second flip flop includes third and fourth control inputs. The third control input is coupled to an output of the edge detect circuit. The second flip flop generates a fourth control signal to control a second switch coupled, via an inductor, to the first switch and the LED.

Abstract: In described examples, a circuit for controlling a light emitting diode (LED) includes a switch control circuit to generate a first control signal for a first switch coupled in parallel with the LED. The switch control circuit generates the first control signal responsive to a magnitude of loop current through the first switch relative to a first reference signal. A switch driver generates a second control signal for a second switch coupled to the first switch via an inductor. The first switch driver generates the second control signal responsive to the magnitude of the loop current through the first switch relative to the first reference signal.
