ABSTRACT:
Flash unit for a camera includes a flash illumination device which illuminates during imaging operations of the camera, and a housing encasing the flash illumination device. The housing is made from a material that transmits infrared light emitted by the flash illumination device to an area outside of the housing. Also disclosed is a camera that includes a built-in flash unit that further includes a flash illumination device which illuminates during operations of the camera. The camera also includes a housing that encases the built-in flash illumination unit. The housing, like the housing of the flash unit, is made from a material that transmits infrared light emitted by the flash illumination device to an area outside of the housing. Also provided is a command module for use by a camera in controlling another device. The command module includes an infrared light source, and a housing that encases the infrared light source. The housing is made from a material that transmits infrared light emitted by the infrared light source to an area outside of the housing. The light emitted by the infrared light source and which is transmitted by the housing is used to control another device. The command module also includes a coupling member connected to the housing for coupling the housing to the camera. The coupling member permits the camera to control the infrared light source.
