Image-processing camera with application processing using acquired image data
View Patent ↗An image pickup device that acquires images is controlled by an image pickup device controller that accepts image acquisition requests from multiple application programs, and an application scheduler selects application programs to be executed. Information indicative of the image data volumes and image data acquisition rates required for each of the multiple application programs is stored and used to select multiple concurrently executable application programs on the basis of the image data volumes and image data acquisition rates. An image acquisition scheduler determines the timing and intervals at which the multiple executable application programs repeat receiving image data from the image pickup device, without overlapping in terms of time. In addition, an operations section, which explicitly presents concurrently executable application programs to a user and commands the startup of these programs, is displayed on a navigation screen menu.
1. An image-processing camera for a vehicle, comprising:
an image pickup device mounted on the vehicle, said image pickup device having a lens, an image pickup element, and an optical system controller that controls said lens and said image pickup element;
a memory storage that stores at least two of the following three applications:
i) an automatic light control application,
ii) a lane deviation alarm application, and
iii) a vehicle alarm application,
which perform image processing for running of the vehicle using an image acquired by said image pickup device based on one or more different camera parameters;
a controller that:
acquires the image used by any two of the automatic light control application, the lane deviation alarm application, and the vehicle alarm application from said image pickup device used in common,
has a schedule for acquiring repeatedly image data used by the two of the three applications in a state which does not overlap in time based on each rate set up for every application, and executing said two of the three applications as a function of time, and
sets up the optical system controller based on predetermined camera parameters, according to said schedule; wherein
setup of the optical system controller and acquisition of the image data from the image pickup element are performed repeatedly based on the schedule of the image data acquisition, as a function of time, and
processing of the two of the three applications is performed using the acquired image data.
2. The image-processing camera according to claim 1 , wherein the image pickup device is directed toward one of a front of the vehicle and a rear of the vehicle.
3. The image-processing camera according to claim 1 , wherein the image data used is assigned to a corresponding frame based on the rates set up by the two of the three applications.
4. The image-processing camera according to claim 3 , wherein setup of the optical system controller and processing of the two of the three applications using the image data are performed repeatedly, based on assignment of the schedule to the frame, as a function of time.
5. The image-processing camera according to claim 1 , wherein the controller that acquires the image used, has the schedule, and sets up the optical system controller determines a camera parameter based on environment information including vehicle exterior illumination.
6. The image-processing camera according to claim 1 , wherein selection of the at least two applications is determined by the speed of the vehicle.
7. The image-processing camera according to claim 2 , wherein the image data used is assigned to a corresponding frame based on the rates set up by the two of the three applications.
8. The image-processing camera according to claim 7 , wherein setup of the optical system controller and processing of the two of the three applications using the image data are performed repeatedly, based on assignment of the schedule to the frame, as a function of time.
9. The image-processing camera according to claim 2 , wherein the controller that acquires the image used, has the schedule, and sets up the optical system controller determines a camera parameter based on environment information including vehicle exterior illumination.
10. The image-processing camera according to claim 2 , wherein selection of the at least two applications is determined by the speed of the vehicle.
