1. A vehicle-mounted camera adapter in a vehicle-mounted monitoring system including a vehicle-mounted camera imaging a surrounding area of a vehicle inclusive of an area in the rear of the vehicle, a monitor device displaying an image or a still image imaged by the vehicle-mounted camera or a similar image and a vehicle-mounted camera adapter relaying the image supplied from the vehicle-mounted camera to the monitor device, the vehicle-mounted camera including:
an image correction unit configured to perform correction conversion of an original image obtained by the vehicle-mounted camera thereby to form a plurality of corrected images; an image switching unit configured to automatically or manually switching the corrected images from a selected one to another; and a top-down image generation unit configured to generate a top-down image obtained by looking down from above, the vehicle-mounted camera adapter comprising: an image relay unit configured to relay the corrected image from the vehicle-mounted camera to the monitor device; a switching control unit configured to supply a normal switching control signal to the image switching unit thereby to control automatic or manual switching of the corrected images, the vehicle-mounted camera adapter being configured to relay the corrected images from the vehicle-mounted camera to the monitor device and to automatically or manually control switching of the corrected images transmitted from the vehicle-mounted camera when backing of the vehicle is started and the corrected image is to be displayed on the monitor device; a detection unit configured to detect a predetermined event indicative of a behavior of a vehicle body to determine whether or not a sequence of backing has proceeded to a final stage, the detection unit including a sensor configured to supply a timer start signal when having detected the event and an event timer configured to measure an execution time of the event when receiving the timer start signal, the event timer being configured to supply a trigger signal to the switching control unit when the event is executed continuously for a predetermined time or more, wherein: when receiving the trigger signal, the switching control unit is configured to supply to the image switching unit a specific switching control signal to switch the converted image displayed on the monitor device to the top-down image; and when the event continues for the predetermined time or more during backing, the vehicle-mounted camera adapter is configured to control the image switching unit so that the top-down image is displayed. |
