Definitions
- the European new car assessment Euro NCAP is expected to further improve the detection performance of in-vehicle cameras in dark environments, such as adding a function to detect pedestrians at night as a target of collision avoidance by automatic braking in 2018 Be
- an illumination technology for illuminating the front is required.
- the vehicle lamp described in Patent Document 1 is described to realize high-intensity illumination as a configuration including a light emitting unit including a phosphor, a laser optical system including a laser light source, a projection lens, and the like. .
- FIG. 1B is a block diagram showing the configuration of the imaging unit (imaging device) 2.
- the imaging unit (imaging device) 2 outputs an imaged image data to the image processing unit 5, and a synchronization signal input terminal 2 b that inputs a synchronization signal of illumination light emission timing as a control signal from the control unit 4. And have. Thus, the imaging operation of the imaging unit 2 is performed in synchronization with the illumination light emission timing of the illumination unit 1.
- the change width of the light flux amount when dimming the illumination light is temporally constant, but in the third embodiment, the case where the change width of the light flux amount can be temporally changeable will be described.
- the change width of the luminous flux amount is also referred to as “light control width”.
- FIG. 10 is a diagram showing an example in which the imaging system is applied to a monitoring camera system.
- the monitoring camera system 12 includes, in addition to the imaging unit (monitoring camera) 2, an illumination unit 1, a light control unit 3 for controlling the illumination unit 1, and a control unit 4 for controlling these.

Abstract
La présente invention concerne un système d'imagerie comprenant : une unité d'éclairage (1) qui émet une lumière d'éclairage sur un sujet photographique ; une unité de réglage de lumière (3) pour régler la quantité de flux lumineux de la lumière d'éclairage émise par l'unité d'éclairage ; une unité d'imagerie (2) pour capturer une image du sujet photographique à l'aide d'un capteur d'image et délivrer un signal d'image ; et une unité de commande (4) pour commander l'unité de réglage de lumière et l'unité d'imagerie. L'unité de commande commande, par l'intermédiaire de l'unité de réglage de lumière, la quantité de flux lumineux et/ou la durée d'émission de la lumière d'éclairage émise par l'unité d'éclairage d'une manière synchronisée avec une trame d'imagerie de l'unité d'imagerie. À titre d'exemple, tout en utilisant deux trames d'imagerie consécutives de l'unité d'imagerie en tant qu'un cycle, l'unité de réglage de lumière règle l'unité d'éclairage de telle sorte que la quantité de flux lumineux L1 de la lumière d'éclairage dans une première trame de l'unité d'imagerie et la quantité de flux lumineux L2 de la lumière d'éclairage dans une seconde trame suivante sont paramétrées à différentes valeurs l'une de l'autre.
