- the imager according to the invention has an evaluation device and an interface to a transmitting and receiving device.
- the imager is a mobile imager.
- the evaluation device according to the invention has an artificial intelligence.
- the artificial intelligence is designed to determine weather information from image information of an image recorded by the imager of at least one area of the atmosphere. Via the interface to the transmitting and receiving device, the weather information determined by the artificial intelligence can be transmitted and / or received.
- An imager is an electronic device for generating an image.
- an image sensor of a digital camera system is an imager.
- An interface is a device between at least two functional units on which an exchange of data or signals takes place, either only unidirectionally or bidirectionally.
- a mobile item is not tied to a fixed location.
- the antonym to mobile is stationary.
- An evaluation device is an electronic circuit that processes incoming information and outputs a result resulting from this processing.
- central processor units or graphics processors are evaluation devices.
- An evaluation device which has an artificial intelligence, is built or programmed so that it can independently process incoming information.
- Artificial intelligence means recreating a human-like intelligence.
- Artificial intelligence can be realized with artificial neural networks.
- An artificial neural network is an algorithm that is executed on an electronic circuit and programmed on the model of the neural network of the human brain.
- Functional units of an artificial neural network are artificial neurons whose output is generally known as Value of an activation function evaluated over a weighted sum of the inputs plus a systematic error, the so-called bias.
- By testing multiple predetermined inputs with different weighting factors and activation functions artificial neural networks, similar to the human brain, are trained or trained.
- the training of artificial intelligence by means of predetermined inputs is called machine learning.
- a subset of machine learning is deep learning, which uses a series of hierarchical layers of neurons, called hidden layers, to perform the machine learning process.
- Image information is information about specific object data, brightness values, etc. in an image.
- the imager it is thus possible to determine weather information from an arbitrary image which shows at least one region of the atmosphere.

- the artificial intelligence determines the weather information after a predetermined period of time.
- the time span can be five minutes. This means that the artificial intelligence only determines the weather information after five minutes after taking the picture. If a plurality of images are taken during this period of time, the artificial intelligence determines the weather information on the basis of the latest after the expiration of the time frame image. Since the weather usually does not change significantly within this predetermined period of time, the most recent image after the time span is sufficient for determining the weather information, which leads to a saving of computing power in the evaluation device.
- the artificial intelligence determines the weather information from a plurality of images, in particular from a predetermined number. Based on several images, the artificial intelligence can detect changes in the weather, especially local changes, when the images were taken in different locations.
- the weather information is preferably provided with a time stamp.
- a timestamp assigns a unique time to an event. With the time stamp statements can be made about the temporal change of the weather.
- position, temperature, pressure, humidity and / or wind strength values or similar weather factors are recorded when the image is taken.
- additional weather factors each represent the weather information beyond the image information of the image and are advantageous for local and detailed weather forecasting.
- the weather information is preferably sent and / or received in real time.
- Real-time means the operation of a device in which information processing programs are always operational, such that the processing results are available within a predetermined period of time.
- the processing of the information does not have to be very fast, it just has to be fast enough for the respective application.
- the position, temperature, pressure, humidity and / or wind strength values or similar weather factors are sent and / or received.
- This allows for comprehensive weather information.
- the image is taken with a mobile imager according to claim 1 and the claims appended to claim 1.
