On the basis of the above-described embodiment, a modified embodiment of the above-described embodiment is further proposed, and it is to be noted herein that, in order to make the description brief, only the differences from the above-described embodiment are described in each modified embodiment.
Wherein, the ambient brightness change information is a brightness change parameter value;
optionally, determining ambient brightness change information within the time period according to the ambient brightness information; selecting an image sensor from the multiple image sensors for preview display or shooting according to the ambient brightness change information may include:
determining the brightness change parameter value according to the environment brightness information;
and selecting an image sensor corresponding to the brightness change parameter value from the multiple image sensors to preview or shoot according to the brightness change parameter value.
Specifically, the brightness change parameter includes a brightness change rising edge and a brightness change falling edge;
the determining the brightness change parameter value according to the environment brightness information may include
Determining a pulse signal corresponding to the ambient brightness information in the time period;
in the pulse signal, a first number of rising edges of the brightness change and a second number of falling edges of the brightness change are determined.
Further, the determining, in the time period, a pulse signal corresponding to the ambient brightness information may include:
determining a function formed by the environment brightness information and the time information collected in the time period according to the time information corresponding to each environment brightness information;
and (4) differentiating the function to determine the pulse signal.
Optionally, the multi-image sensor comprises a first image sensor and a second image sensor; the working environment brightness corresponding to the first image sensor is smaller than the working environment brightness corresponding to the second image sensor;
the selecting, according to the brightness change parameter value, an image sensor corresponding to the brightness change parameter value from among the multiple image sensors for preview display or shooting may include:
when the first number is zero and the second number is larger than zero, selecting the first image sensor to preview or shoot;
and when the first number is larger than zero and the second number is zero, selecting the second image sensor for previewing or shooting.
Optionally, the multi-image sensor comprises a first image sensor and a second image sensor; the working environment brightness corresponding to the first image sensor is smaller than the working environment brightness corresponding to the second image sensor;
the selecting, according to the brightness change parameter value, an image sensor corresponding to the brightness change parameter value from among the multiple image sensors for preview display or shooting may include:
when the difference value between the first quantity and the second quantity is larger than a first preset threshold value and the second quantity is smaller than a second preset threshold value, selecting the first image sensor to preview or shoot;
and when the difference value between the second quantity and the first quantity is greater than the first preset threshold value and the first quantity is smaller than the second preset threshold value, selecting the second image sensor to preview or shoot.
Optionally, obtaining ambient brightness information; setting the sampling rate according to the acquired environment brightness information; or receiving sampling rate information set by a user, and setting the sampling rate according to the sampling rate information;
and setting the time period according to the set sampling rate.
Examples of the present invention are illustrated.
As shown in fig. 2, the camera (image capture function module) opening process in the embodiment of the present invention includes:
step 12, selecting a proper image sensor from a group of image sensors according to the read brightness data of the current environment;
and step 13, previewing and displaying in real time based on the selected image sensor. Of course, in this case, all image sensors may be turned on and a preview may be output, or only the selected image sensor may be turned on and a preview may be output. Note that a plurality of image sensors are turned on, but only one of them is actually output for preview display.
As shown in fig. 3, after the camera is opened, the method includes:
1) acquiring the ambient brightness within T seconds before the current moment according to a certain sampling rate through a light sensor or an image sensor, and judging whether to start switching every other time period of T seconds;
the value of the time period T depends on the sampling frequency of the light sensor or the image sensor to the brightness signal, and if the sampling frequency is more than 10 times/second, the value of the time period T is recommended to be about 3 seconds;
if the acquisition frequency is lower than 0.5 times/second, the camera is judged to be switched or not as long as the light sensation change is detected, and the device does not meet the practical use condition.
In other cases, the value of T is suggested to be about 6 seconds;
according to the relationship between the collected time and the corresponding brightness information data, a function f (t) formed by the collected ambient brightness information and the time information in each time period is determined as shown in fig. 4.
A plot of sampled data acquired at 10 data per second with an acquisition time period T of 5 seconds is shown in fig. 5.
In other words, the sampling rate in this example can be preset in two ways:
for example, the sampling rate is set according to the acquired ambient brightness information.
For another example, receiving sampling rate information set by a user, and setting the sampling rate according to the sampling rate information.
And further setting a time period according to the set sampling rate. For example, as the sampling rate decreases, the time period increases.
In this example, the sampling rate is adjusted, and the time period is set according to the sampling rate, so that the balance between the performance and the effect can be obtained.
2) Designing a brightness detection mechanism to judge whether to start switching every other time period of T seconds;
calculating the difference of F (t) is equivalent to the derivation process.
As shown in fig. 6, the pulse signal reflects the change of the ambient brightness.
For the convenience of control, the change of the brightness data in a time period T before the current time point is calculated, the following information needs to be counted: number of rising EDGEs RISE _ EDGE of brightness change; number of falling EDGEs of brightness change FALL _ EDGE; the conditions for the brightness change are: when the adjacent luminance difference | DIFF | > DIFF _ THR, it is considered that the ambient luminance has changed. DIFF _ THR is preset data, which is related to the characteristics of the light-sensing sensor (light-sensing range), and can be obtained by collecting a large amount of data and analyzing.
Fig. 7 is a graph obtained by calculating the difference between adjacent absolute values in the data of fig. 5, and if DIFF _ THR is set to 100, the data of fig. 7 has two consecutive rising edges, and the switching may be performed considering the ambient brightness increase at this time.
3) If the brightness change satisfies the condition, it is also necessary to detect a sensor (image sensor) switching execution condition: whether a photo is started or not is included; whether to enable a flash lamp; whether or not mode switching is performed.
And step 22, setting a basic switching mechanism model according to the information, and selecting a proper image sensor for real-time preview display or photographing. As shown in fig. 8, the basic switching mechanism model includes:
If yes, step 32 is executed to perform the switching, and if the time interval is T, step 31 is executed.
And step 33, if not, acquiring the brightness information change parameter in the current time period.
Step 34, determining whether RISE _ EDGE is 0 and FALL _ EDGE is greater than 0, if yes, executing step 35; if not, go to step 36.
Step 36, determining whether RISE _ EDGE >0 and FALL _ EDGE is 0, if yes, executing step 37; if not, go to step 38.
Step 38, determining whether there is risk _ EDGE-wall _ EDGE > THR1 (a first preset threshold), and wall _ EDGE < THR2 (a second preset threshold), if yes, executing step 37; if not, go to step 39.
The embodiment of the invention can effectively ensure the smooth switching between the image sensors, effectively solve the false switching caused by the influence of accidental light sensation change of the environment and effectively solve the phenomenon of back-and-forth switching.
