The embodiment of the invention discloses a kind of camera method of controlling rotation and terminal, camera can be realized and rotate with friction speed.Below be described in detail respectively.
Refer to Fig. 1, the schematic flow sheet of Fig. 1 a kind of camera method of controlling rotation disclosed in the embodiment of the present invention.As shown in Figure 1, this camera method of controlling rotation can comprise the following steps:
The target rotated for controlling camera that S101, detection user input in camera preview interface touches slide.
In the embodiment of the present invention, said method can be applied to the intelligent terminal being configured with rotatable camera (as electronic rotation camera) and touch-screen, as smart mobile phone, panel computer, palmtop PC etc.For ease of understanding and describing, be applied to smart mobile phone (hereinafter referred to as mobile phone) for said method below.
In the embodiment of the present invention, when user is taken by mobile phone, user can control camera by assigned operation gesture and rotate, to adjust shooting visual angle.
Such as, by both hands, user can refer to that in camera preview interface, touch slip controls camera rotation, or by one hand, user can refer to that in camera preview interface, touch slip controls camera rotation.
S102, determine that this target touches the sliding speed of slide.
In Alternate embodiments one, determine that target touches the sliding speed of slide, can comprise:
At the end of this target slide being detected, according to the time that this target slide continues, and this target touches sliding distance corresponding to slide, determines that this target touches the sliding speed of slide.
In this Alternate embodiments one, mobile phone detects that user is when the target rotated for controlling camera that camera preview interface inputs touches slide, at the end of this target touches slide, just can control camera and rotate.
Particularly, when mobile phone detects that user touches slide in the target rotated for controlling camera that camera preview interface inputs, mobile phone can be added up this target and touch the slide lasting time, and this target touches sliding distance corresponding to slide; At the end of mobile phone detects target slide, mobile phone can touch the slide lasting time according to added up target, and this target touches sliding distance corresponding to slide, determines that this target touches the sliding speed of slide.
Such as, suppose at the end of mobile phone detects that target touches slide, the time that the target of mobile phone statistics touches slide lasting is t, and the sliding distance that target touches slide corresponding is s, then this target touches the sliding speed v=s/t of slide.
In Alternate embodiments two, determine that target touches the sliding speed of slide, can comprise:
Before detecting that target touch slide terminates, obtain this target every predetermined time period and touch the sliding distance of slide in this predetermined time period;
According to the sliding distance in this predetermined time period, determine that this target touches the sliding speed of slide in this predetermined time period.
In this Alternate embodiments two, mobile phone detects that user is when the target rotated for controlling camera that camera preview interface inputs touches slide, can touch in the time-continuing process of slide in this target, control camera in real time and rotate.
Particularly, when mobile phone detects that user touches slide in the target rotated for controlling camera that camera preview interface inputs, mobile phone can touch before slide terminates in target, every predetermined time period, (this predetermined time period can be arranged according to actual scene, as 100ms, 200ms etc.) obtain the sliding distance of target touch slide in Preset Time, and according to the sliding distance in this Preset Time, determine that target touches the sliding speed of slide in this Preset Time.
Such as, mobile phone is when detecting that user touches slide in the target rotated for controlling camera that camera preview interface inputs, target can be obtained every 200ms and touch the sliding distance of slide in this Preset Time, suppose that the sliding distance of this target slide in certain 200ms that mobile phone gets is △ s, then mobile phone can determine that this target touches slide is △ s/200ms in the sliding speed of this Preset Time.
S103, determine corresponding rotary speed according to this sliding speed.
As the optional execution mode of one, in embodiments of the present invention, rotating with friction speed to realize camera, the corresponding relation (i.e. the corresponding relation of sliding speed and rotary speed) touching the sliding speed of slide and the rotary speed of camera can be pre-set.After mobile phone determination target touches the sliding speed of slide, mobile phone according to the corresponding relation of the sliding speed pre-set and rotary speed, can determine the rotary speed that the sliding speed of target touch slide is corresponding.Preferably, touch the sliding speed of slide to be directly proportional to the rotary speed of camera.
For example, suppose the corresponding relation of sliding speed and the rotary speed pre-set as shown in table 1 (wherein, v3 > v2 > v1, this rotary speed is motor of camera rotating speed, lower with):
Table 1
| Sliding speed (mm/s, millimeter is per second) | Rotary speed (r/s, revolution per second) |
| (0，v1] | n1 |
| (v1，v2] | n2 |
| (v2，v3] | n3 |
| … | … |
If it is v2 that mobile phone determination target touches the sliding speed of slide, then mobile phone can sliding speed according to this sliding speed question blank 1 and the corresponding relation of rotary speed, determines that the rotary speed of this sliding speed (v2) correspondence is n2.
As the optional execution mode of another kind, in embodiments of the present invention, rotate with friction speed to realize camera, the default rotary speed of camera can be pre-set, and the touch sliding speed of slide and the corresponding relation (i.e. the corresponding relation of sliding speed and regulatory factor) of camera rotary speed regulatory factor are set.After mobile phone determination target touches the sliding speed of slide, mobile phone can according to the corresponding relation of the sliding speed pre-set and regulatory factor, determine the target regulatory factor that the sliding speed of target touch slide is corresponding, and then according to this target regulatory factor and default rotary speed, determine the rotary speed that the sliding speed of target touch slide is corresponding.
For example, the corresponding relation of sliding speed and the regulatory factor (R) pre-set (wherein, v3 > v2 > v1) as shown in table 2 is supposed:
Table 2
| Sliding speed (mm/s) | R |
| (0，v1] | R1 |
| (v1，v2] | R2 |
| (v2，v3] | R3 |
| … | … |
If the sliding speed that mobile phone determination target touches slide is v1, then mobile phone can the corresponding relation of sliding speed according to this sliding speed question blank 2 and regulatory factor, determine that regulatory factor corresponding to this sliding speed (v1) is R1, then mobile phone can determine that the rotary speed that target touches the sliding speed of slide corresponding is v0*R1 (supposing that default rotary speed is v0).
S104, control camera rotate with this rotary speed.
In the embodiment of the present invention, mobile phone determination target can control camera and rotate with this rotary speed after touching rotary speed corresponding to the sliding speed of slide.
As the optional execution mode of one, if mobile phone is at the end of detecting that target touches slide, just control camera and rotate (Alternate embodiments one namely in corresponding above-mentioned steps S102), at the end of then mobile phone detects that target touches slide, the sliding speed that the target can determined according to self touches slide determines corresponding rotary speed (target rotational speed), controls camera and rotates with this target rotational speed.
In this optional execution mode, after above-mentioned steps S104, can also comprise the following steps:
