Definitions
- the invention relates to a method for displaying a cooking process carried out in a cooking device on a display, the cooking device being equipped with a cooking space, at least one heating device for heating the cooking space, and with an operating device for selecting cooking programs, and with a camera taking pictures from the The cooking space.
- the invention also relates to a system for carrying out such a method.
- the invention thus has the problem of disclosing a method and a system with which the viewing of cooking processes is more appealing.
- the advantages that can be achieved with the invention result from a method for displaying a cooking process carried out in a cooking device on a display, the cooking device being equipped with a cooking space, at least one heating device for heating the cooking space, and with an operating device for selecting cooking programs, and whereby a camera takes pictures from the cooking chamber.
- a control device collects images recorded by the camera and combines the collected images into a time-accumulated representation of the cooking process on the display, possibly with the generation and addition of intermediate images that represent the transitions of two consecutive images collected. To this way, a documentation of the cooking process can be generated that shows all the important phases in this process in a very appealing and concise manner.
- the images are collected in a suitable storage medium, which can be part of the cooking appliance, but also an external storage medium, for example a cloud.
- the storage medium can, however, also be assigned to an external device, for example a mobile device, that has a display for displaying the film produced, for example a smartphone or a tablet.
- the control device can also be part of the cooking appliance, an external computer or part of the smartphone or tablet. It is possible to collect all the captured images and use them to create the film, but it may also be practical to either collect only a portion of the captured images or to use only a portion of the collected images to create the film. Corresponding algorithms must then be processed in the control device for this purpose. The number of images generated and collected depends in particular on the data rate at which the images recorded can be transferred to the storage medium. For short cooking processes and / or at low data rates, it can therefore be advantageous if the control device generates and inserts one or more intermediate images, which represent the transition between these images, between two consecutive images collected.
- the control device decides on the basis of the number of images collected whether the number falls below a minimum value, exceeds a maximum value or lies between the minimum value and the maximum value;
- the control device decides whether there is a sufficient number of images in order to be able to produce a film either with intermediate images (alternative b) or even without intermediate images (alternative c). It is particularly advantageous if the number of images makes it possible to produce a film according to the PAL standard, ie with at least 25 images per second. If this is not possible, only a single image is shown instead of a film, for example the last one recorded. It is particularly advantageous if the control device defines a maximum duration for the time-lumped display of the cooking process, and if, depending on the number of images collected, the maximum duration is either not reached or, if necessary, adhered to by increasing a frame rate R or omitting collected images.
- the maximum duration is advantageously between 5 and 10 seconds, in particular around 6 seconds. If the cooking process is short and / or the data rate is low, then a movie is produced that is shorter than the maximum duration. It is advantageous if the duration does not fall below a minimum of 2 seconds.
- the maximum duration can be set in the control device, but it can also be selected by a user input.
- the user input can be made on the operating device, directly on the control device, on the camera or on the display.
- the control device collects images at equidistant points in time of the cooking process. This can take place either in that the camera records images at equidistant points in time or in that the control device only collects images from an abundance of images from previously determined equidistant points in time.
- the control device calculates times in the cooking process at which the camera records images or at which the control device collects recorded images.
- the influence on the food to be cooked is relatively small at the beginning, so it can be more interesting to use more images from the end of the cooking process to create the film.
- the recorded images could also be evaluated and only those images in which the rate of change exceeds a predetermined amount can be used for the creation of the film. To do this, however, there would have to be more images than are needed to create the film.
- control device optimizes the recorded or collected images for the time-gathered display before they are used.
- the optimization can contain a lens correction (correcting lens distortions) and / or a gamma correction (brightness and contrast) and / or a re-sharpening. This improves the quality of the film.
- the advantages that can be achieved with the invention also result from a system which comprises a cooking appliance, a camera, a display, an operating device and a control device and which is suitable and designed for carrying out a method according to at least one of the preceding claims.
- the display can be an integral part of the cooking appliance, for example in a control panel, but also as part of the appliance door. However, it can also advantageously be part of an external device (smartphone, tablet, laptop, PC, TV device) to which the control device sends the time-gathered representation of the cooking process.
- the camera can also be permanently installed in the cooking device, but it can also be designed separately as an external camera or be part of a mobile device (tablet, smartphone), which is either placed in the cooking space (very high requirements would have to be met here to the heat resistance) or take photos from the outside through a transparent window, for example in the door of the device.
- the camera can either be part of the device in which the display is arranged, but it can also be designed as a third, separate device or module.
- the term camera is to be interpreted broadly; the camera can comprise one or more image capturing devices; it can be suitable for capturing images in the visible range, but also in the IR range, or in combinations thereof.
- the part of the control device that carries out the image optimization described above can also be fully or partially integrated into the camera.
- the control device itself can also be integrated into the cooking device, but it can also be completely or partially outsourced from the device, for example in a cloud or an external control computer, or even in the external device in which the display and / or the camera are located is located.
- the operating device which can also be permanently installed in the cooking device, for example in a control panel located above a device door, but also in the door itself.
- the operating device can of course also be part of the external device in which the display and / or the camera is located. Or it can represent another external device or be part of the same.
- control device comprises a control computer and a communication device for transmitting data within the control device and / or between the control device and the operating device and / or the camera and / or the display.
- the control computer can be part of the cooking appliance or it can be an external device. However, it can be partially integrated into the cooking appliance and form the device control there and partially outsourced to an external device, for example in a cloud or in an external control computer. It can even be wholly or partially a component of the external device in which the display and / or the camera are located.
- the communication device must be suitable for the transmission of data between parts of the control computer and / or between the control computer and the operating device and / or the camera and / or the display can be wired and / or use radio, telecommunications, Bluetooth, NFC, WLAN or LAN. There is also the possibility that the type of data transmission between the individual components of the system is different.
- FIG. 1 An embodiment of the invention is shown purely schematically in a drawing and is described in more detail below.
- the figure shows a system 1 according to the invention with an external monitoring device in the form of a mobile terminal 3, a cooking device in the form of an oven 5 and a central computer unit 7 which is operated by the manufacturer of the oven 5 in the manner of a cloud system.
- the oven 5 has a cooking space 9 in which heating devices, here two top heat radiators 11 and an annular heating element 13 with a circulating air fan, are arranged.
- heating devices here two top heat radiators 11 and an annular heating element 13 with a circulating air fan, are arranged.
- food 15 brought into the cooking space 9, hereinafter referred to as food 15, can be warmed or heated and thereby at least partially cooked.
- this warming / heating process is referred to as the cooking process.
- the oven 5 can of course also be equipped with other heating devices, not shown, such as radiant heaters, bottom heaters, microwave sources, steam sources or the like.
- In the cooking space 9 there is also a food support 17 on which the food 15 can be positioned for carrying out the cooking process.
- the oven 5 is equipped with a control device 18 in the form of a control panel 19, which is indicated in Figure 1 by the dashed rectangle.
- Various cooking processes can be selected with the control panel 19, which usually differ in terms of parameters such as the duration, the type of heating, the calorific values provided for the respective heating device and, if necessary, additional functions such as steaming, flavoring and much more.
- a specific program can then be set in which the aforementioned parameters, with the exception of the duration, are fixed.
- the duration must either be set additionally, or the user simply ends the cooking process by switching off the power supply to the heating devices.
- so-called automatic programs can also be selected, in which the user then only provides information about the nature of the food and, if necessary, additional information about the desired target state.
- the device control then automatically selects the aforementioned parameters and controls the cooking process, possibly taking into account sensor-recorded data from the process.
- control panels 19 there are also control panels 19 in which mixed forms of these two operating principles can be found. Suitable control panels 19 are sufficiently known from the prior art and are therefore not shown in more detail in the figures.
- ovens 5 to enable operation via an app on the mobile terminal 3. With this it can Program set and then started or even just a program preset on the oven 5 with the control panel 19 can be started remotely. In such systems 1, it is then often provided that information about the cooking process is sent from the oven 5 to the mobile terminal 3 via this app and is displayed there. Of course, it is also possible that the oven 5 is operated by means of a first mobile terminal and the information about the cooking process is sent to one or more other mobile terminals.
- the oven 5 is equipped with a camera 21 which can record images from the cooking space 9.
- the camera 21 is directed into the cooking space 21 in such a way that it is used to detect the food 15 when it is positioned on the food carrier 17.
- the device control 23 of the oven 5 is part of a control computer 25 of the control device 27, which in addition to its usual tasks, i. H. the control of the cooking process on the basis of the selected program, here also controls the camera 21 and causes it to take pictures of the cooking space 9 and thus of the food 15 to be cooked.
- the images of a cooking process are sent via a communication module 29, which is part of a communication device 31, to the central computer unit 7, which is also part of the control computer 25 and thus part of the control device 27.
- the recorded images are collected in the central computer unit 7 and initially optimized by various correction methods such as lens correction and / or gamma correction and / or re-sharpening.
- the computer unit 7 then combines the collected and optimized images into a film with a time-lumped representation of the cooking process, possibly with the generation and addition of intermediate images.
- the film should have no less than a minimum duration T min and no more than a maximum duration T max .
- Individual images with a frame rate R are put together.
- the individual images can be the optimized images, but they can also be intermediate images which the computer unit 7 calculates from two successive optimized images and which represent the transition between two such optimized images. Several intermediate images can represent the transition between two optimized images. At least one image number A of optimized images should be used per second of film.
- the frame rate R is a value of at least 25 frames per second according to the PAL standard Recommended, the number of images A should be around five or not fall below this value.
- the minimum duration T min should not be less than two seconds, the maximum duration not more than ten seconds, six seconds can be assumed here as an advantageous value.
- T min * A Zmin recorded and optimized images by the camera 21 are available. Be maximum
- T max * R Zmax recorded and optimized images required by the camera 21.
- the computer unit 7 produces only a single image instead of a film, for example the last optimized image. If there are at least Z max or even more than Z max optimized images, the computer unit 7 produces a film with a time-lumped representation of the cooking process, which only consists of optimized images. If there are more images than Z max , either the frame rate R is increased or individual optimized images up to a number Z max are selected from the total set. If there is a number of optimized images between Zmin and Zmax, the computer unit 7 produces intermediate images. In addition, if the number of optimized images is not sufficient for a film with the maximum length - the number is then less than
- the computer unit 7 can collect and use images from equidistant points in time for the film; the film then correlates with the cooking process over time. Alternatively, however, there is also the option of selecting specific times of the cooking process as a function of the selected cooking program, at which the camera 21 records images. Or the computer unit 7 selects from the total number of collected or already optimized images only or in a larger number those from specific points in time of the cooking process. Such special points in time of the cooking process can consist of time segments in which change processes in the food to be cooked 15 are greater, or they can be images in which the rate of change is greater than a predetermined threshold value.
- the film with the time-lumped representation of the cooking process or the individual image can then be shown on a display 33.
- this display 33 can be part of the mobile terminal 3.
- the communication between the computer unit and the mobile terminal 3 then takes place via a further part of the communication device 3, namely via a second Internet connection 35.
- the representation on the display 33 and the establishment of the second Internet connection 35 between the computer unit 7 and the mobile terminal 3 can be components of the above-mentioned app or a separate app.
- the display 33 is part of the oven 5 and is permanently built into it (not shown).
