Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 shows a schematic diagram of a power tree of a camera module according to an embodiment of the present invention. The Camera Module may be a Complementary Metal Oxide Semiconductor (CMOS) Camera Module (CCM), and includes a sensor, a lens, and other modules. The power supply for supplying power to the camera module may include three power supplies, which are a first power supply, a second power supply, and a third power supply, respectively. The power supply of each path may include a Low Dropout Regulator (LDO).
The first power supply (LDO1) supplies power to an Analog unit of the camera module, the Analog unit may include an Analog circuit of the photosensitive element, and the first power supply may be referred to as an Analog power supply (also referred to as an Analog Voltage Device, or AVDD for short). The second power supply (LDO3) supplies power to a Digital unit of the camera module, where the Digital unit may include a Digital circuit of the photosensitive element, and the second power supply may be referred to as a Digital power supply (also referred to as a Digital Voltage Device, DVDD). The third power supply (LDO2) supplies power to an interface unit of the camera module, where the interface unit may include an I2C (Inter-Integrated Circuit) interface, and the third power supply may be referred to as a Digital IO power supply (also referred to as a Digital IO Voltage Device, or DOVDD for short). The specification of the camera module can have voltage values provided by each power supply when the camera module can normally work, wherein the voltage values include a minimum (Min) value, a Type value and a maximum (Max) value. Specifically, as shown in table 1:
TABLE 1
| Description of the invention | (symbol) | Min value (V) | Type value (V) | Max value (V) |
| Digital power supply | DVDD | 0.95 | 1.05 | 1.15 |
| Analog power supply | AVDD | 2.7 | 2.8 | 2.9 |
| Digital IO power supply | DOVDD | 1.7 | 1.8 | 1.9 |
The resolution of the camera module is divided into two modes, namely a full-size (also called remote full-size, and english of the remote full-size is remosic full-size) mode and a combining size (combining size) mode. The binding size mode includes two modes, a preview and on 3D HDR (high-dynamic range image) mode and a preview and off 3D HDR mode. Under the condition that the camera module works at different frame rates and different resolutions (sizes), the difference of the working currents of all paths of power supplies is large.
Fig. 2 is a schematic diagram showing voltages and currents of the power supplies for supplying power to the camera module according to an embodiment of the present invention. As shown in fig. 2, taking the DVDD as an example that the voltage supplied to the camera module is 1.05V, when the resolution of the camera module is Remosic full-size and the frame rate is 30fps, the current of the DVDD is 431 mA; in the case where the resolution of the camera module is preview and 3D HDR is off, and the frame rate is 30fps, the current of the DVDD is 94.5 mA. Therefore, the difference between the currents is more than 300 milliamperes, and the difference is large.
The circuit configuration of present camera module is in order to guarantee that even camera module work is at maximum current (for example the mode of operation of camera module is remosic full-size to the frame rate is 30fps), also can satisfy the voltage that the power provided to the camera module and be greater than the minimum to guarantee that the camera module can normally work.
In addition, considering the voltage drop of the routing impedance R (200 and 500m Ω), the power output voltage of the camera module is set to be a fixed value at the upper limit. Taking the DVDD in table 2 as an example, considering the maximum working current 431mA of the 300m Ω trace impedance, the path voltage drop will be about 0.12V. At this time, in order to ensure that the working voltage of the digital unit of the camera module is greater than the minimum value, even if the frame rate and the resolution of the camera module are different, the voltage value of the DVDD for supplying power to the digital unit of the camera module is fixed to be 1.15V.
In order to ensure that the camera module can operate under a large current, the method of increasing the operating voltage of the camera module to a fixed value causes the voltage of the camera module operating in another mode (for example, 1/4full-size mode) to be higher, and the corresponding power consumption also increases. As can be seen from fig. 2, in the mode of previewing and turning off the 3D HDR, the DVDD supplies an operating current of 94.5mA to the camera module, which is relatively small, so that the camera module can operate normally even considering the drop of the path impedance set to 1.0V. In general, when a camera is used for a long time in a scene such as a video chat, the requirement for pixels is lower than the requirement for photographing, and the camera is set to a mode of previewing and turning off 3D HDR. Set up operating voltage on the high side under long-time job scenario (actually 1.0V can satisfy the demand, but set to the highest 1.15V), lead to the power consumptive increase of camera module. Therefore, the service life of the whole machine is shortened, and the surface temperature rise of the whole machine is increased. Under some conditions, the temperature of the camera can exceed the standard, and the service life of the camera is shortened.
Based on the above analysis, fig. 3 shows a schematic flow chart of a camera power supply method according to an embodiment of the present invention. The camera power supply method is applied to electronic equipment, and the electronic equipment comprises a camera module and a power supply for supplying power to the camera module. The camera power supply method is applied to the electronic equipment, and as shown in fig. 3, the camera power supply method includes:
The target resolution may be in two modes, i.e., a Remosic full-size mode and a binding size mode. The binding size mode may include preview and on 3D HDR mode, preview and off 3D HDR mode. However, the division between the mode of the target resolution and the binding size mode is not limited herein.
Before step 101, the camera power supply method may further include determining whether to start a camera module; step 101 comprises: and acquiring target working parameters of the camera module under the condition of opening the camera module.
And 102, determining a target working voltage associated with the target working parameter according to a preset association relationship between the working parameter of the camera module and the working voltage of the camera module.
The incidence relation between the working parameters of the camera module and the working voltage of the camera module can be a one-to-one correspondence relation or a functional relation between the working parameters and the working voltage. For example, in the Remosic full-size mode, the correlation between the frame rate of the camera module and the operating voltage of the camera module is a function f1(x) (ii) a In the binding size mode, the correlation between the frame rate of the camera module and the working voltage of the camera module is a function f2(x)。f1(x) And f2(x) Respectively, the operating voltage of the camera module, and x represents the frame rate of the camera module. Thus, by function f1(x) Or function f2(x) The target operating voltage may be calculated.
The incidence relation between the working parameters of the camera module and the working voltage of the camera module can be the incidence relation between the working parameters of the camera module and the lowest working voltage of the camera module. In this way, the target operating voltage determined according to the association relationship is the lowest target operating voltage, thereby controlling the power supply to supply a voltage greater than or equal to the lowest target operating voltage to the camera module. Therefore, the camera module can work at a lower voltage, and the power consumption of the camera module is reduced.
And 103, controlling the power supply to provide a voltage which is greater than or equal to the target working voltage for the camera module according to the target working voltage.
Optionally, a difference between the target supply voltage and a voltage provided by the power supply to the camera module is within a predetermined voltage range. Therefore, the voltage provided by the power supply to the camera module is equal to or close to the target working voltage.
In the embodiment of the invention, the target working voltage associated with the target working parameter of the camera module is determined, and the power supply is controlled to supply voltage to the camera module according to the target working voltage. Therefore, under the condition that the camera module works with different working parameter values, the voltages provided by the power supply to the camera module can be different. Therefore, the camera module is supplied with power according to the voltage requirement of the camera module, the camera module can work at a lower voltage, unnecessary power consumption of the camera module during shooting is reduced, the problem that the power consumption of the electronic equipment during shooting is larger is solved, and the service life of the whole electronic equipment is prolonged. In addition, because the camera module works at a lower voltage, the overhigh temperature of the camera module can be avoided, and the service life of the camera module is prolonged.
Optionally, in one or more embodiments of the present invention, the power supply input terminal of the camera module is connected to the power supply output terminal of the power supply through a wire.
For example, with continued reference to fig. 1, power input terminal a of the camera module is connected to power output terminal B of power LDO1 through a wire.
Since the wire has a resistance, if the operating voltage is detected at a position close to the power supply output terminal B, for example, at a position D, the operating voltage detected at the position D is the sum between the operating voltage supplied from the power supply LDO1 to the camera module and the voltage of the wire from the position D to the input terminal a. Therefore, the operating voltage detected at a position close to the power supply output terminal B does not accurately indicate the operating voltage supplied from the power LDO1 to the camera module.
In one or more embodiments of the present invention, the operating voltage in the correlation relationship is: detecting the working voltage of the camera module at a preset position on the lead under the condition that the camera module works according to the working parameters in the incidence relation;
wherein a distance between the predetermined position and the power supply input terminal is smaller than a distance between the predetermined position and the power supply output terminal.
For example, with continued reference to fig. 1, power input terminal a of the camera module is connected to power output terminal B of power LDO1 through a wire. Under the condition that the camera module works at different frame rates and different resolutions, the working voltage provided by the LDO1 to the camera module is detected at the preset position C on the lead by taking the impedance voltage of the lead into consideration. That is, the operating voltage is detected at a position close to the power supply input terminal a, and is not detected at a position close to the power supply output terminal B (for example, at a position D). Therefore, the operating voltage detected at the position C can more accurately represent the operating voltage provided by the power LDO1 to the camera module.
According to the embodiment of the invention, the working voltage is detected at the position close to the power supply input terminal of the camera module, so that the influence caused by the impedance voltage drop of the path can be considered, and the detection result is more accurate. And the operating voltage of the camera module is actually measured, so that the camera module can work at the required operating voltage under the states of different frame rates and different resolutions. Instead of operating at the same voltage without distinguishing the state of the camera module. Therefore, the embodiment of the invention can optimize the power consumption of the camera module according to the actual working scene of the camera module, reduce unnecessary power consumption, save the power consumption of a battery, prolong the service life of the whole camera and improve the temperature rise problem of the camera module.
Optionally, in one or more embodiments of the present invention, the camera power supply method further includes:
and setting the incidence relation between the working parameters of the camera module and the working voltage of the camera module.
Wherein, a one-to-one correspondence between the combination of the resolution and the frame rate and the operating voltage of the camera module can be set. For example, the correspondence relationship shown in table 2 below may be set.
As can be seen from table 2 below, the frame rate and the operating voltage of the camera module may have a positive correlation with the same resolution. In the case of the same frame rate, the resolution and the working voltage of the camera module may be in a positive correlation.
In addition, the frame rate may not be positively correlated with the operating voltage of the camera module. The resolution ratio and the working voltage of the camera module group do not have a positive correlation. For example, the correspondence relationship shown in table 3 may be set.
The following is a one-to-one correspondence between the combinations of resolution and frame rate and the operating voltage of the camera module shown in table 2:
TABLE 2
The following is a one-to-one correspondence between the combinations of resolution and frame rate and the operating voltage of the camera module shown in table 3:
TABLE 3
The embodiment of the invention can preset the incidence relation between the working parameters of the camera module and the working voltage of the camera module. Thus, the target working voltage associated with the target working parameter is determined according to the preset association relation. So that the target operating voltage can be more conveniently determined.
Optionally, in one or more embodiments of the invention, the power source comprises at least one of a first power source, a second power source, and a third power source. The first power supply supplies power to an analog unit in the camera module, the second power supply supplies power to a digital unit in the camera module, and the third power supply supplies power to an interface unit in the camera module.
Step 102 includes at least one of:
determining a first working voltage associated with a target working parameter according to a preset association relationship between the working parameter of the camera module and the working voltage of the analog unit;
determining a second working voltage associated with the target working parameter according to the preset association relationship between the working parameter of the camera module and the working voltage of the digital unit;
and determining a third working voltage associated with the target working parameter according to the preset association relationship between the working parameter of the camera module and the working voltage of the interface unit.
Step 103 comprises at least one of:
controlling a first power supply to provide a voltage which is greater than or equal to a first working voltage to the analog unit according to the first working voltage corresponding to the analog unit;
controlling a second power supply to provide a voltage which is greater than or equal to a second working voltage to the digital unit according to the second working voltage corresponding to the digital unit;
and controlling a third power supply to provide a voltage which is greater than or equal to the third working voltage for the interface unit according to the third working voltage corresponding to the interface unit.
According to the embodiment of the invention, the lower working voltage is respectively provided for at least one of the digital unit, the analog unit and the interface unit of the camera module, so that the lower power consumption of at least one of the digital unit, the analog unit and the interface unit of the camera module can be realized, and the consumption of the electric quantity of the battery can be saved. At least one unit can be flexibly selected from the digital unit, the analog unit and the interface unit according to requirements, and a lower working voltage is provided for the at least one unit, so that the requirements of users are met.
As an example, in the case where the power supply includes a first power supply, a second power supply, and a third power supply, step 102 includes:
determining a first working voltage associated with a target working parameter according to a preset association relationship between the working parameter of the camera module and the working voltage of the analog unit;
determining a second working voltage associated with the target working parameter according to the preset association relationship between the working parameter of the camera module and the working voltage of the digital unit;
and determining a third working voltage associated with the target working parameter according to the preset association relationship between the working parameter of the camera module and the working voltage of the interface unit.
Step 103 comprises:
controlling a first power supply to provide a voltage which is greater than or equal to a first working voltage to the analog unit according to the first working voltage corresponding to the analog unit;
controlling a second power supply to provide a voltage which is greater than or equal to a second working voltage to the digital unit according to the second working voltage corresponding to the digital unit;
and controlling a third power supply to provide a voltage which is greater than or equal to the third working voltage for the interface unit according to the third working voltage corresponding to the interface unit.
