Description

[0061] Figure 8 A block diagram of a distance determination device according to an exemplary embodiment is shown. Detailed Implementation

[0062] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0063] In electronic devices, such as mobile phones, when an obstruction blocks the screen, the closer the obstruction is to the infrared proximity sensor, the higher the background noise value received by the sensor. When the background noise value received by the infrared proximity sensor exceeds a certain threshold, it is determined that an obstruction is approaching, and the electronic device reports a proximity status, thus performing operations such as waking up the screen. This threshold is the proximity threshold. Conversely, when the background noise value received by the infrared proximity sensor is less than another threshold, it is determined that no obstruction is approaching, and the electronic device reports a distance status, thus keeping the screen from being woken up. This threshold is the distance threshold.

[0064] However, when the obstruction gets close enough to the phone, the infrared energy path reflected to the infrared distance sensor is blocked, causing the noise floor value received by the infrared distance sensor to decrease. This can lead to the oil stain algorithm mistakenly identifying the obstruction as oil stain and optimizing it out, resulting in an error in the reported status and causing screen wake-up errors, such as the phone's anti-mistouch function failing, automatic brightness adjustment malfunctioning, or abnormal screen on / off during calls.

[0065] This disclosure provides a distance determination method that combines light-sensing data and data obtained from an infrared distance sensor, and uses an oil stain algorithm to solve the problem of misinterpreting an obstruction as oil stains and causing incorrect status reporting when the obstruction is too close to the screen of an electronic device. It accurately judges the distance between the obstruction and the screen and precisely determines whether it is an oil stain signal, thereby improving the accuracy of screen wake-up.

[0066] This disclosure provides a distance determination method applied to an electronic device, exemplarily used to determine the distance state between an obstruction and the screen of the electronic device. Figure 1 This is a flowchart of a distance determination method according to an exemplary embodiment of this disclosure, see reference. Figure 1 As shown, the distance determination method includes the following steps:

[0067] Step S110: Determine whether the data acquired by the infrared distance sensor of the electronic device is greater than the distance threshold and less than the first proximity threshold.

[0068] Step S120: If yes, acquire light sensing data;

[0069] Step S130: Determine whether the light sensing data is greater than the preset light sensing value;

[0070] Step S140: If yes, determine the second proximity threshold value;

[0071] Step S150: Determine the positional state between the obstruction and the screen of the electronic device based on the second proximity threshold and the data obtained by the infrared distance sensor.

[0072] The distance determination method provided in this disclosure is used to accurately determine the distance between an obstruction and the screen of an electronic device, so as to accurately determine whether the obstruction is oil or grease and avoid errors in the status reporting of the infrared distance sensor. First, a first proximity threshold and a distance threshold of the electronic device's screen are acquired, along with data acquired by the infrared distance sensor, such as the noise floor value. The data acquired by the infrared distance sensor is then compared with the first proximity threshold and the distance threshold. When it is determined that the data acquired by the infrared distance sensor is greater than the distance threshold and less than the first proximity threshold, the screen's light sensitivity is assessed. After acquiring the light sensitivity data, if it is determined that the currently acquired light sensitivity data is greater than a preset light sensitivity value, a second proximity threshold is determined. Then, based on the second proximity threshold and the data acquired by the infrared distance sensor, the positional status between the obstruction and the screen of the electronic device is accurately determined and reported.

[0073] The distance determination method provided in this disclosure not only compares the data acquired by the infrared distance sensor with a first proximity threshold and a distance threshold as the basis for judging the positional state between the obstruction and the screen of the electronic device, but also combines light sensing data to make a judgment and determine a second proximity threshold. Then, based on the second proximity threshold and the data acquired by the infrared distance sensor, the positional state between the obstruction and the screen of the electronic device is accurately judged, effectively preventing status reporting errors.

[0074] Figure 2 This is illustrated according to an exemplary embodiment. Figure 1 The implementation flowchart of step S140 in the illustrated embodiment is shown below. Figure 2 As shown, in this embodiment, when the light-sensing data is determined to be greater than a preset light-sensing value, a second proximity threshold value is determined, including the following steps:

[0075] Step S141: When the light sensing data is determined to be greater than the preset light sensing value, the oil stain algorithm is invoked;

[0076] Step S142: Determine the second proximity threshold based on the oil stain algorithm and the first proximity threshold.

[0077] In this scheme, the second proximity threshold is greater than the first proximity threshold. This can also be understood as using an oil stain algorithm to increase the first proximity threshold by one magnitude, thereby obtaining the second proximity threshold. The magnitude of this increase, i.e., the difference or multiple between the second and first proximity thresholds, can be determined based on the first proximity threshold and the oil stain algorithm.

[0078] When the data obtained by the infrared distance sensor of the electronic device is greater than the distance threshold but less than the first proximity threshold, and the current light sensing data is greater than the preset light sensing value, the oil stain algorithm is called to adjust the first proximity threshold to obtain the second proximity threshold. Then, based on the second proximity threshold and the data obtained by the infrared distance sensor, the positional state between the obstruction and the screen of the electronic device is accurately determined. This can effectively avoid mistaking the obstruction for oil stains for optimized reporting and ensure the screen's response accuracy.

[0079] Figure 3 This is illustrated according to an exemplary embodiment. Figure 1 The implementation flowchart of step S150 in the illustrated embodiment is shown below. Figure 3 As shown, in this embodiment, the positional state between the obstruction and the screen of the electronic device is determined based on the second proximity threshold and the data obtained by the infrared distance sensor, including the following steps:

[0080] Step S151: If the data obtained by the infrared distance sensor is greater than the second proximity threshold, it is determined that the distance between the obstruction and the screen of the electronic device is less than the first preset distance.

[0081] Step S152: If the data obtained by the infrared distance sensor is less than the second proximity threshold, it is determined that the distance between the obstruction and the screen of the electronic device is greater than the second preset distance.

[0082] The first preset distance is less than the second preset distance. When the distance between the obstruction and the screen of the electronic device is less than the first preset distance, it is determined that the obstruction is approaching the screen of the electronic device, and a proximity status is reported; when the distance between the obstruction and the screen of the electronic device is greater than the second preset distance, it is determined that the obstruction is moving away from the screen of the electronic device, and a moving-away status is reported. In other words, when the data obtained by the infrared distance sensor is greater than the second proximity threshold, it is determined that the obstruction is approaching the screen of the electronic device, a proximity status is reported, and the screen is woken up; when the data obtained by the infrared distance sensor is less than the second proximity threshold, it is determined that the obstruction is moving away from the screen of the electronic device, a moving-away status is reported, and the screen does not need to be woken up.

[0083] Figure 4 This is illustrated according to an exemplary embodiment. Figure 1 Supplementary flowcharts of the illustrated embodiments, such as Figure 4 As shown, the distance determination method provided in this embodiment further includes:

[0084] Step S160: If the light sensing data is less than the preset light sensing value, determine that the distance between the obstruction and the screen of the electronic device is less than the first preset distance.

[0085] When the data acquired by the infrared distance sensor of the electronic device is greater than the distance threshold but less than the first proximity threshold, and the current light sensing data is greater than a preset light sensing value, as described above, a second proximity threshold is determined, and the positional state between the obstruction and the screen of the electronic device is judged based on the second proximity threshold. Conversely, when the data acquired by the infrared distance sensor of the electronic device is greater than the distance threshold but less than the first proximity threshold, and the current light sensing data is less than a preset light sensing value, it can be directly determined that the distance between the obstruction and the screen of the electronic device is less than a first preset distance, i.e., it is determined that the obstruction is close to the screen of the electronic device, the proximity status is reported, and the screen is woken up.

[0086] Figure 5 This is illustrated according to an exemplary embodiment. Figure 1 Supplementary flowcharts of the illustrated embodiments, such as Figure 5 As shown in the embodiments of this disclosure, the distance determination method further includes:

[0087] Step S170: If the data obtained by the infrared distance sensor of the electronic device is less than the distance threshold, it is determined that the distance between the obstruction and the screen of the electronic device is greater than the second preset distance.

[0088] After acquiring the first proximity threshold and the distance threshold of the screen of the electronic device, as well as the data acquired by the infrared distance sensor, such as the noise floor value, when it is determined that the data acquired by the infrared distance sensor is less than the distance threshold, it is not necessary to acquire light sensing data again. It can be directly determined that the distance between the obstruction and the screen of the electronic device is greater than the second preset distance, that is, it is determined that the obstruction is far away from the screen of the electronic device, and the distance status is reported.

[0089] Figure 6 This is illustrated according to an exemplary embodiment. Figure 1 Supplementary flowcharts of the illustrated embodiments, such as Figure 6 As shown, the distance determination method provided in this embodiment further includes:

[0090] Step S180: If the data obtained by the infrared distance sensor of the electronic device is greater than the first proximity threshold, it is determined that the distance between the obstruction and the screen of the electronic device is less than the first preset distance.

[0091] After acquiring the first proximity threshold and the distance threshold of the screen of the electronic device, as well as the data acquired by the infrared distance sensor, such as the noise floor value, when it is determined that the data acquired by the infrared distance sensor is greater than the first proximity threshold, it is not necessary to acquire the light sensing data and the second proximity threshold. It can be directly determined that the distance between the obstruction and the screen of the electronic device is less than the first preset distance, that is, it is determined that the obstruction is close to the screen of the electronic device, and the proximity status is reported.

[0092] In one exemplary embodiment, the distance determination method proceeds as follows:

[0093] Acquire the first proximity threshold and distance threshold of the screen of the electronic device, as well as data acquired by the infrared distance sensor, such as the noise floor value;

[0094] If the data obtained by the infrared distance sensor of the electronic device is greater than the first proximity threshold, it is determined that the distance between the obstruction and the screen of the electronic device is less than the first preset distance, and the proximity status is reported.

[0095] If the data obtained by the infrared distance sensor of the electronic device is less than the distance threshold, it is determined that the distance between the obstruction and the screen of the electronic device is greater than the second preset distance, and the distance status is reported.

[0096] When the data acquired by the infrared distance sensor of the electronic device is greater than the distance threshold and less than the proximity threshold, light sensing data is acquired.

[0097] If the light sensor data is less than the preset light sensor value, it is determined that the distance between the obstruction and the screen of the electronic device is less than the first preset distance, and the proximity status is reported.

[0098] If the light sensor data is greater than the preset light sensor value, the oil stain algorithm is invoked;

[0099] The second proximity threshold is determined based on the oil contamination algorithm and the first proximity threshold.

[0100] If the data obtained by the infrared distance sensor is greater than the second proximity threshold, it is determined that the distance between the obstruction and the screen of the electronic device is less than the first preset distance, and the proximity status is reported.

[0101] If the data obtained by the infrared distance sensor is less than the second proximity threshold, it is determined that the distance between the obstruction and the screen of the electronic device is greater than the second preset distance, and the distance status is reported.

[0102] The distance determination method provided in this disclosure, based on data acquired by an infrared distance sensor, a first proximity threshold, a distance threshold, light sensing data, and an oil stain algorithm, accurately distinguishes the positional state between the obstruction and the screen of the electronic device at multiple levels.
