Motion picture camera with additional electronic equipment

The present invention relates to improvements in cameras for taking or recording images on a moving one Pad, such as film cameras and video cameras that use an electronic, magnetic, or optical Image recording device can be connected.

When shooting a company, a certain amount of general information relating to the shooting of the film and other more specific information relating to the recording of a sequence or sequence of scenes must be recorded. The general information may relate to, for example, d ± e number of the camera used, the movie title, the name of the operator and the type of film used, while in the specific information for the different sequences of the starting and ending time point of each sequence, the rotational speed of the The value of the aperture used or the used value of the focal length of the lens, etc. can be recorded.

It is the object of the present invention to automatically register all different for with very simple means the utilization of the recordings to enable useful information while shooting.

i_ For this purpose, this device is used to take pictures

on a moving surface or a film, such as a film or video camera, which is attached to a magnetic Image recording device can be connected, provided according to the invention with a microprocessor with a memory. Further be Facilities for recording and holding various recording criteria are provided, which are initially stored in a working memory entered and then all or partially transferred to the movable image substrate.

According to a further improvement of the invention, the receiving apparatus a timer or clock running through a logic circuit controlled by the "walk-and-stop" breaker is connected to the memory in order to enter into the memory the exact "*) times of the start and end of each rotation sequence.

In addition, the memory can have an area in which predetermined duration information is recorded that is necessary for this are intended to be marked on the recording sheet.

The device according to the invention has the advantage that it can be found at the end of each day by reading the contents of the Apparatus built-in memory is possible to provide all technical information related to various that occurred during rotation Receive current events. In this way it is very easy to determine the start and end times · of any sequence that To know the apertures used for each sequence, the focal lengths of the lenses, the rotation speeds, etc.

There are several ways to read this information are provided, of which two different methods are mentioned in more detail here. On the one hand, it is possible to use the To remove the memory itself from the film camera so that its contents can be read in a suitable device, the The memory is replaced the next day by another memory preloaded with all the desired information.

In a modified embodiment, however, it is also possible to leave the memory permanently in the film camera and the information it contains in an external one with to the first connectable memory. The memory previously built into the film camera can then also be used The general information contained therein is exchanged for new information which is output from the external memory will.

Further details, features and advantages emerge from the following description of a schematically illustrated drawing Embodiment.

The drawing is of the physical characteristics of a movie camera schematically shows an objective 1, which a sequence of images 2 on a photosensitive film 3 maps. The film 3 is moved step by step by an electric motor 4. The usual gripper mechanism is for simplicity omitted from illustration. Of course, with such a commonly used mechanism, the film can 3 step to be advanced step by step.

According to the invention, the film camera has a microprocessor provided with a memory 5 with two areas 5a and 5b on. In the area 5a of the memory 5 there is the general information relating to the rotation, such as information the number of the camera, the title of the film being shot, the name of the operator, the type of film used etc. recorded.

The other area 5b of the memory 5 contains the special information relating to each of the sequences filmed during the day. Which concerns one of these pieces of information the start and end times of each sequence. to

*. for this purpose the camera has a timer or clock 6

which emits coded, time-related signals at its output. These signals are sent to the memory 5 by a logical Transfer circuit 7, which in turn is controlled by an on and off switch 8 of the camera. So will each time the camera is started, the start time of the sequence is entered into memory and when the Operator releases the interrupter 8, this is the end time of the sequence, which is then entered in the area 5b.

In this area 5b of the memory, other information relating to the various turning conditions can likewise be entered will. The focal length of the lens used can thus be scanned with the aid of a signal generator 9 or a sensor will,

which is connected to the lens 1 in such a way that it emits a coded signal at the output which represents the focal length. This signal is applied to the memory 5 in that ^: it passes through the logic circuit 7.

Under the same conditions, another sensor for a coded signal 10 can emit a signal at its output, which represents the aperture used. This sensor 10 is also connected to the memory 5 via the logic Circuit 7 connected.

The speed at which the film is turned is also can be recorded. For this purpose, a selector switch 11 controls the image rhythm, the one with the supply of the motor 4 is connected to the electric current controlling circuit 12, also a transmitter 13 for a coded Signal, whereby a signal appears at the output of the encoder, which represents the selected picture rhythm. This signal is transmitted to the memory 5 via a logic circuit 7.

It is clear that for each rotation in the area 5b of the memory 5 special information pertaining to this episode can be recorded.

The camera according to the invention also has a marking device 14, which is connected to the output of the memory 5, in order to receive certain information in an edge zone of the film 3 to mark which come from the memory 5a with the general information. It can do so with the help of the marking device 14 the information, the name of the operator, the camera used, the name of the production (Movie title), etc., can be recorded.

However, other information can also be provided if this is desired from area 5b which contains the specific information for each sequence.

At the end of the day, the memory 5 can be pulled out of the camera and through another memory that stores the new information related to the turning that is to take place later, concerns, be exchanged.

However, it can also use an output terminal 15, which is connected to the output of the memory 5, the whole Information contained in this memory is transferred to an external memory for further processing.

In the first case, when the memory 5 is removable, it should be easily transportable, for example within a microcassette or a mini floppy disk or the like. In the second case, that is, if the memory is in left with the camera, it may consist of conventional solid state storage such as magnetic tape storage or similar. However, it can also be an assignable and erasable RAM.

According to a modified embodiment, the camera can have a colorimetric recording device 16, which the measures the colorimetric quality of the Aufmähmelichtes, this Recording device is connected to the logic circuit 7 like the other signal sensors. In this way it is possible on the film during the recording sequence with the help of the marking device 14 information relating to the colorimetric To record the quality of the exposure light, q 3QQAQ / 0721
