Changes in ambient light intensity are detected by processing image data from an image capture device to determine, iteratively, a signal-to-noise ratio of the image data. The signal-to-noise ratio is a ratio of average to variance of pixel values for some of the pixels forming the image. A control outputis generated, based on the signal-to-noise ratio, that is responsive to changes in ambient light intensity. The control output is used control a light source of a vehicle.

An input voltage stabilization circuit for a rear combination lamp includes: an optical output unit including a plurality of Organic Light Emitting Diodes (OLEDs); a voltage converter; and a feedback unit. The voltage converter is configured to supply an output voltage for driving the plurality of OLEDs by converting a first voltage supplied by a vehicle battery to the output voltage, the output voltage being different from the first voltage. The feedback unit is configured to provide, as feedback to the voltage converter, information regarding a maximum voltage value for the plurality of OLEDs. The voltage converter is further configured to adjust the output voltage based on the information provided as feedback by the feedback unit regarding the maximum.

A light emitting element driving device includes a receiver that receives a predetermined communication signal transmitted across a communication line, a generator that generates a reference signal based on the start time point of a start bit in the predetermined communication signal, and a determiner that determines, based on the reference signal, the timing of switching a light emitting element from extinction to lighting. The predetermined communication signal is a signal in which the start bit with a first logic level is transmitted at a prescribed period from a transmitter and in which the data bits succeeding each start bit do not have a second logic level a predetermined number of times or more consecutively.

The present technology relates to a vehicle that enables to improve designability while avoiding deterioration of safety and functionality of the vehicle.

The vehicle includes: a front line extending in a vehicle width direction on a front surface of a body; and a headlight arranged on left and right of the front surface, divided vertically by the front line, and configured to output a low beam from a portion above the front line and output a high beam from a portion below the front line. The present technology can be applied to, for example, a vehicle.
