Description

[0001] Colour Calibration System and Method for Aerosol Provision Device

[0002] Technical Field

[0003] The present application relates to the field of aerosol provision technology, particularly to a colour calibration system and method for an aerosol provision device.

[0004] Background

[0005] In the product design of electronic cigarettes (also known as aerosol provision devices), RGB LEDs are commonly used to indicate puffing, charging, and error status. After the LEDs are assembled into the product, users may observe colour deviations in the emitted light of some electronic cigarettes. This occurs due to tolerances in the LED current, meaning not all devices meet the same current precision. Additionally, the colour of the electronic cigarette housing may also cause interference, leading to further colour deviations in the LED light emission. As a result, users may perceive variations in the emitted LED colours.

[0006] The conventional solution is to add an LED driver chip, as shown in Figure 1, to ensure stable and accurate LED current. However, this approach requires additional chips and circuit design, leading to increased costs, and the deviation caused by the device housing colour remains unresolved.

[0007] Therefore, there is an urgent need for a colour calibration method for a light source of an aerosol provision device to solve one or more of the above-mentioned problems.

The aerosol-modifying agent may, for example, comprise one or more of a flavourant, a colourant, water, and a carbon adsorbent. The aerosol-modifying agent may, for example, be a solid, a liquid, or a gel. The aerosol-modifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.

[0066] An aerosol generator is an apparatus configured to cause aerosol to be generated from the aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy, so as to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosol-generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy. The present disclosure relates to aerosol delivery systems (which may also be referred to as vapour delivery systems) such as nebulisers or e-cigarettes. Throughout the following description the term "e-cigarette" or "electronic cigarette" may sometimes be used, but it will be appreciated this term may be used interchangeably with aerosol delivery system I device and electronic aerosol delivery system I device. Furthermore, and as is common in the technical field, the terms "aerosol" and "vapour", and related terms such as "vaporise", "volatilise" and "aerosolise", may generally be used interchangeably.

[0067] Aerosol delivery systems (e-cigarettes) often, though not always, comprise a modular assembly comprising a reusable device part and a replaceable (disposable / consumable) cartridge part. Often, the replaceable cartridge part will comprise the aerosol-generating material and the vaporiser (which may collectively be called a "cartomizer") and the reusable device part will comprise the power provision (e.g. rechargeable power source) and control circuitry. It will be appreciated these different parts may comprise further elements depending on functionality. For example, the reusable device part will often comprise a user interface for receiving user input and displaying operating status characteristics, and the replaceable cartridge device part in some cases comprises a temperature sensor for helping to control temperature. Cartridges are electrically and mechanically coupled to the control unit for use, for example using a screw thread, bayonet, or magnetic coupling with appropriately arranged electrical contacts. When the aerosol-generating material in a cartridge is exhausted, or the user wishes to switch to a different cartridge having a different aerosol-generating material, the cartridge may be removed from the reusable part and a replacement cartridge attached in its place. Systems and devices conforming to this type of two-part modular configuration may generally be referred to as two-part systems / devices.

[0068] It is common for electronic cigarettes to have a generally elongate shape. For the sake of providing a concrete example, certain embodiments of the disclosure will be taken to comprise this kind of generally elongate two-part system employing disposable cartridges. However, it will be appreciated that the underlying principles described herein may equally be adopted for different configurations, for example single-part systems or modular systems comprising more than two parts, refillable devices and single-use disposables, as well as other overall shapes, for example based on so-called box-mod high performance devices that typically have a boxier shape. More generally, it will be appreciated certain embodiments of the disclosure are based on aerosol delivery systems which are operationally configured to provide functionality in accordance with the principles described herein and the constructional aspects of systems configured to provide the functionality in accordance with certain embodiments of the disclosure is not of primary significance.

[0069] As described in the background, conventional colour calibration method for a light source of an aerosol provision device using driver chips require additional chips and circuit designs. On one hand, this increases product hardware costs; on the other hand, it fails to overcome colour deviations in the emitted light caused by interference from the device's housing colour.

[0070] In light of this, the embodiments of the present application innovatively propose a novel colour calibration method for a light source of an aerosol provision device. This method eliminates the need for additional chips or circuit designs while effectively resolving colour deviation issues in the emitted light caused by interference from the device's housing colour.

[0071] Embodiment 1

[0072] Figure 2 is a flowchart of a colour calibration method for a light source of an aerosol provision device according to some embodiments of the present application. As shown in Figure 2, the method comprises:

[0073] S100: detecting the actual RGB display values when a light source of an aerosol provision device is emitting light.

[0074] The colour calibration method for an aerosol provision device provided in the embodiments of the present application may be applicable to colour calibration of various light sources, and may be particularly suitable for LED light sources. Any suitable light sources may be provided as the light source in the present application. In embodiments, the light source in the embodiments of the present application may be an LED light source.

[0075] The following description of the embodiments of the present application will use LED light sources as exemplary embodiments for illustrative purposes.

[0076] As noted in the background, the LED light sources exhibit current tolerances, and not all aerosol provision devices meet their required current precision specifications. Consequently, this leads to colour deviation in the emitted light colour of the LEDs. Furthermore, the colour of the electronic cigarette housing may also cause interference, leading to further colour deviations in the LED light emission. To address the aforementioned issues, the embodiments of the present application propose a novel colour calibration method for an aerosol provision device. The method offers dual advantages: firstly, it eliminates the need for additional chips or circuit designs, thereby avoiding increased hardware costs; secondly, it effectively resolves both types of colour deviations - those caused by insufficient current precision and those induced by housing colour interference.

[0077] It should be noted that the embodiments of the present application do not impose limitations on the specific means of detecting the actual RGB display values when a light source of an aerosol provision device is emitting light. Without departing from the inventive concept of this application, any known detection method may be employed to measure the actual RGB display values. By way of example and not limitation, the embodiments of the present application may utilize external detection equipment to measure the actual RGB display values of the light source emission from outside the aerosol provision device. This approach enables the detected RGB display values to inherently account for colour deviations in the LED's emitted light caused by colour interference from the device's housing.

[0078] S200: when there is a display error between the actual RGB display values and the preset standard RGB display values, adjusting the RGB channel data of the light source of the aerosol provision device, until the re-detected actual RGB display values match the standard RGB display values.

[0079] In an optional embodiment, the present application employs the RGB colour model to characterize the light source's colouration. It should be understood that the RGB colour model represents an industry-standard colour system that generates diverse colours through variations and combinations of three primary colour channels: Red (R), Green (G), and Blue (B). The RGB designation precisely corresponds to these three chromatic channels, encompassing virtually the entire gamut of human visual perception, thereby constituting one of the most widely adopted colour systems in current use.

[0080] Based on the above content and as shown in Figure 3, compared to existing solutions that utilize LED driver chips, the hardware design in the embodiment of the present application no longer incorporates an LED driver chip. Instead, the R / G / B signals of the light source may be directly connected to the General-Purpose Input / Output (GPIO) pins of the device's microcontroller (MCU). The MCU may control the LED_B or LED_G or LED_R current, thereby adjusting the colour information of the LED's R, G, and B channels to adjust colour deviations. In implementation, when a display error is detected between the actual RGB display values and the preset standard RGB display values, the RGB channel data of the light source of the aerosol provision device may be adjusted (i.e., by controlling the LED_B or LED_G or LED_R current via the MCU). This adjustment continues until the re-detected actual RGB display values match the standard RGB display values.

[0081] It can be understood that the embodiments of the present application may employ a matching algorithm to align the actual RGB display values with the preset standard RGB display values. It should be noted that the embodiments of the present application do not impose specific limitations on the matching algorithm. Any known matching algorithm may be used in this application. Furthermore, the specific representation of the matching result is not restricted. Without departing from the inventive concept of this application, the specific representation method may be configured according to actual requirements. For example, the matching result may be expressed numerically (such as a percentage) or as a binary indication (e.g., "matched" or "unmatched"). These examples are not exhaustive, and users may define the representation format based on their practical needs.

[0082] In an optional embodiment, before detecting the actual RGB display values when the light source of the aerosol provision device is emitting light, the method further comprises: configuring the RGB channel data of the light source of the aerosol provision device according to the standard RGB display values.

[0083] It can be understood that in the embodiments of the present application, when the actual RGB display values detected from the aerosol provision device's light source match the standard RGB display values, it may be determined that there is no colour deviation in the light source's emission. Otherwise, a colour deviation is confirmed. Therefore, as an optional embodiment, before detecting the actual RGB display values when the light source of the aerosol provision device is emitting light, the RGB channel data of the light source may be pre-configured according to the standard RGB display values. For instance, target currents for each channel may be determined based on the standard RGB display values. The microcontroller (MCU) can then regulate the current of each channel to achieve these target currents.

[0084] It can be understood that each colour channel (R, G, B) may have values ranging from 0 to 255, representing the intensity or brightness of that colour component. For example, the RGB value of a white LED may be (255, 255, 255), the MCU may control the LED_R, LED_G, and LED_B currents at 12.5mA, 7.5mA, and 7.5mA respectively. The RGB value of a black LED may be (0, 0, 0), and the MCU may set the LED_R, LED_G, and LED_B currents to 0mA each.

[0085] It should be noted that the embodiments of the present application do not impose specific limitations on the standard RGB display values. Without departing from the inventive concept of this application, users may configure these values according to actual product requirements. For example, in some embodiments, the standard RGB display values may be the RGB display values of a standard light source when emitting light (such as calibration instruments, standard aerosol provision devices, or any other standardized equipment). In other embodiments, the standard RGB display values may be derived through any other appropriate standardization method (the specific approaches are not exhaustively listed here).

[0086] In an optional embodiment, the standard RGB display values may have identical values across all three channels. For example, when the light source emits white light, the standard RGB values may be configured as (255, 255, 255).

[0087] It should be understood that the standard RGB display values and actual RGB display values correspond to the same predefined colour or colour grade.

[0088] In an optional embodiment, identifying an image of the light emitted by the light source of the aerosol provision device by using a machine vision detection equipment to output the actual RGB display values.

[0089] It should be noted that the embodiments of the present application impose no limitations on the specific means of obtaining actual RGB display values. Without departing from the inventive concept of this application, any known detection method may be employed. By way of example but not limitation, machine vision detection equipment may be used to identify an image of the light emitted by the light source of the aerosol provision device and thereby output the actual RGB display values.

[0090] In specific implementations, the image of the light emitted by the light source of the aerosol provision device may be acquired. The image data may be then converted into colour patch data through a colour chart, and the colour patch data undergoes demosaicing processing to obtain the corresponding RGB channel data (i.e., the actual RGB display values). The demosaicing processing methods include, but are not limited to: obtaining colour filters at the image sensor end by using a CFA filter, and performing bilinear interpolation on the colour filters to derive the RGB channel data. These methods will not be exhaustively described here.

[0091] In an optional embodiment, a display error between the actual RGB display values and the standard RGB display values may be determined based on any one of the following: a first difference between the R channel value in the actual RGB display values and the R channel value in the standard RGB display values may be greater than a preset R channel threshold; a second difference between the G channel value in the actual RGB display values and the G channel value in the standard RGB display values may be greater than a preset G channel threshold; and, a third difference between the B channel value in the actual RGB display values and the B channel value in the standard RGB display values may be greater than a preset B channel threshold.

[0092] It should be understood that the standard RGB display values may be configured as reference values. The detected actual RGB display values may be compared against the standard RGB display values, and when any discrepancy is detected between them, it may be determined that colour deviation exists in the light source's emission. It should be noted that when comparing the actual RGB display values with the standard RGB display values, if there is any deviation in the data of either channel (R, G, or B), it is determined that a deviation exists between the two sets of values. For example, suppose the RGB value of a standard white LED is (255,255,255), but a white LED in an aerosol provision device with colour deviation mixes some purple inside. When measured by a machine vision LED detection device, the RGB value of the LED is (255, 240, 255. It can be observed that the value of channel G is slightly lower than the standard value. In this case, it is determined that there is a deviation between the RGB value of standard white LED and the measured RGB value.

[0093] It should be noted that the embodiments of this application do not limit the specific numerical ranges of the R channel threshold, R channel threshold, and R channel threshold. Without departing from the inventive concept of this application, users may set these thresholds according to actual requirements.

[0094] In an optional embodiment, the R channel threshold may be greater than or equal to 0;

[0095] In an optional embodiment, the G channel threshold may be greater than or equal to 0; In an optional embodiment, the B channel threshold may be greater than or equal to 0.

[0096] In an optional embodiment, the actual RGB display value may be determined to match the standard RGB display value when all of the following are satisfied: the first difference between the R channel value in the actual RGB display values and the R channel value in the standard RGB display values does not exceed the preset R channel threshold.; the second difference between the G channel value in the actual RGB display values and the G channel value in the standard RGB display values does not exceed the preset G channel threshold, and the third difference between the B channel value in the actual RGB display values and the B channel value in the standard RGB display values does not exceed a preset B channel threshold.

[0097] It can be understood that the standard RGB display value may be configured as the reference value. When comparing the detected actual RGB display value with the standard RGB display value, a match may be determined only when the data of all channels meet the requirements— that is, the difference in each channel's data does not exceed its corresponding threshold. This means the aerosol provision device's light source exhibits no colour deviation in in the light source's emission.

[0098] In an optional embodiment, adjusting the RGB channel data of the light source of the aerosol provision device may comprise: determining a reference channel value from the three channel values of the actual RGB display values; and adjusting the channel values of the other channels based on the reference channel value.

[0099] It can be understood that when adjusting the RGB channel data of the light source of the aerosol provision device, a reference channel value may first be determined among the three channel values of the actual RGB display value, and then the other channel values may be adjusted based on the reference channel value. For example, assume the standard RGB value is (255, 255, 255), and the actual RGB display value of the light source of the aerosol provision device detected when it is emitting light is (255, 240, 255). If the G channel value of 240 is determined as the reference channel value, the other channel values may then be uniformly set to 240 via command line. This would adjust the RGB channel data of the light source of the aerosol provision device to (240, 240, 240). It should be noted that after adjusting the RGB channel data of the light source of the aerosol provision device to (240, 240, 240), although there remains a certain deviation from the standard RGB value (255, 255, 255), the adjusted light output is closer to the colour corresponding to the standard RGB value compared to the original actual RGB display value of (255, 240, 255). This adjustment helps mitigate colour deviation caused by interference from the device's housing colour during illumination, thereby improving colour consistency to some extent.

[0100] In an optional embodiment, determining the reference channel value from the three channel values of the actual RGB display values may comprise: using the maximum value among the first difference, the second difference, and the third difference as a target difference; and determining the channel value corresponding to the target difference as the reference channel value.

[0101] It should be understood that, as an optional embodiment, the maximum value among all channel differences between the actual RGB display value and the standard RGB display value may be taken as the target difference, and the channel value corresponding to the target difference may then be determined as the reference channel value. For example, assume the standard RGB display value is (255, 255, 255) and the actual RGB display value of the light source of the aerosol provision device detected when it is emitting light is (255, 240, 255). Then the first difference is 0, the second difference is 15, the second difference is 15. Among these three channels, the second difference (15) corresponding to the G channel is the maximum value. Therefore, the second difference may be taken as the target difference, and the channel value (240) corresponding to the target difference may be determined as the reference channel value.

[0102] In an optional embodiment, adjusting the channel values of the other channels based on the reference channel value may comprise: adjusting the channel values of the other channels to match the reference channel value; or, determining a target value based on the reference channel value and a preset adjustment threshold, and adjusting the channel values of the other channels based on the target value.

[0103] In some specific embodiments, when adjusting the channel values of the other channels based on the reference channel value, the channel values of the other channels may be adjusted to be the same as the reference channel value. For example, assume the standard RGB display value is (255, 255, 255) and the actual RGB display value of the light source of the aerosol provision device detected when it is emitting light is (255, 240, 255). If the G channel value of 240 is determined as the reference channel value, the other channel values may then be uniformly configured to 240 through command line operations, resulting in adjusted RGB channel data of (240, 240, 240) for the light source of the aerosol provision device.

[0104] In other specific embodiments, when adjusting the channel values of the other channels based on the reference channel value, the target value may first be determined based on both the reference channel value and a preset adjustment threshold, and then the channel values of the other channels may be adjusted according to the target value. It should be noted that in the embodiments of the present application, neither the preset adjustment threshold nor the target value is specifically limited. Without departing from the inventive concept of this application, users may configure these parameters according to actual requirements.

[0105] In an optional embodiment, determining the reference channel value from the three channel values of the actual RGB display values may further comprise: determining whether the maximum value among the first difference, the second difference, and the third difference falls within a preset range; if so, using the maximum value among the first difference, the second difference, and the third difference as the target difference.

[0106] It should be noted that in the embodiments of the present application, the preset range is not specifically limited. Without departing from the inventive concept of this application, it can be configured according to actual product requirements. As an exemplary but non-limiting illustration, the preset range may be any value not exceeding 30. For example, the preset range may be set to not exceed 30, not exceed 25, not exceed 20, not exceed 15, etc. These examples are not intended to be exhaustive.

[0107] In an optional embodiment, adjusting the RGB channel data of the light source of the aerosol provision device may comprise: determining a target channel where the difference between the actual RGB display values of the light source and the preset standard RGB display values exists; adjusting the target channel based on the difference corresponding to the target channel.

[0108] In some specific embodiments, channel where a difference exists between the actual RGB display values and the preset standard RGB display values may be determined as a target channels, and then the target channel may be adjusted according to the corresponding difference of the target channel. For example, assume the standard RGB display value is (255, 255, 255) and the actual RGB display value of the light source of the aerosol provision device detected when it is emitting light is (255, 240, 255). The G channel with a difference is determined as the target channel, with a measured deviation value of 15. In this case, the G channel value may be configured to 255 through command-line operations, resulting in adjusted RGB channel data of (255, 255, 255) for the light source of the aerosol provision device.
