A mirror for camera system includes a substrate, a mirror layer, a fluorescent layer and an excitation window layer. The substrate is provided at a position opposed to an objective lens of an infrared camera, and transmits visible light and infrared light. The mirror layer is provided on a main surface of the substrate, which is the side opposed to the infrared camera, and reflects visible light and transmits infrared light. The fluorescent layer is provided in at least a part of the surface of the mirror layer, and emits at least infrared light as a result of receiving predetermined excitation light. The excitation window layer is provided so as to cover the fluorescent layer, and transmits the excitation light and reflects, at least, the infrared light.

An insect trap and a method of using the same. The insect trap includes a housing. The insect trap also includes a glue board receiving space located inside the housing. The insect trap further includes one or more light sources for attracting insects into the housing. The insect trap also includes a camera having a lens. The lens has a front element. The camera is positioned to capture images of a glue board when the glue board is received in the glue board receiving space. There is no line of sight between the or each light source and the front element of the lens. This may prevent light from the or each light source reaching the front element directly. The method can include using an image captured by the camera to determine that a glue board received in the glue board receiving space needs to be replaced.

An assembly is disclosed. In an embodiment an assembly includes a light source configured to illuminate a field of view, a control circuit configured to operate the light source and a camera configured to record a scene in the field of view, wherein the light source comprises at least one semiconductor component having at least one semiconductor chip, wherein the semiconductor chip has an semiconductor layer sequence with an active region, wherein the semiconductor chip comprises the plurality of pixels, wherein the plurality of pixels are configured to generate radiation of the light source, wherein the control circuit has a memory configured to store operational data of the light source, wherein the control circuit is configured to operate the pixels on basis of the operational data, and wherein the arrangement is configured to perform an adaptation of at least a part of the operational data in the memory during operation of the arrangement.

An image processing system avoids at its best restrictions in determining applicable facilities. The image processing system includes a camera for photographing a workpiece, an illumination device having light transmittance and disposed between the camera and the workpiece, and a control device for controlling the camera and the illumination device. The illumination device can change illumination patterns according to instructions from the control device. The control device controls the camera so that photographs are taken under each illumination pattern.
