Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example one
Referring to fig. 1, which illustrates an apparatus 10 for focused imaging according to an embodiment of the present invention, where the apparatus 10 may be applied to a mobile terminal with a shooting function, such as a smart phone, a tablet computer, a notebook computer, and the like, the apparatus 10 may include: acquisition module 101, selection module 102 and processing module 103
The acquisition module 101 is configured to receive a first instruction to acquire image information and generate a preview image; wherein the acquiring image information comprises: acquiring object information through a camera lens and acquiring coordinate information corresponding to the object information through a sensor;
the selecting module 102 is configured to receive a second instruction to select the first object information in the preview image;
the processing module 103 is configured to perform focusing processing on the preview image according to the selected first object information and the coordinate information of the first object.
It can be understood that in the focusing imaging apparatus 10 provided in this embodiment, the collecting module 101 utilizes the propagation wave to perform the distance measurement of the scenery through the sensor, and performs the focusing of the framing preview image according to the distance measurement of the propagation wave, so that the focusing process is not affected by the external light environment, and the distance between the main camera lens and the shot object can still be collected for focusing the framing preview image under the condition of low illuminance.
For example, in the focusing imaging apparatus 10 shown in fig. 1, the acquisition module 101 may specifically include an image pickup lens having auto-focusing and shooting functions as shown in fig. 2, and may select shooting parameters such as a focal length range, a lens field angle, and an aperture size according to requirements for shooting. When the mobile terminal starts the device 10 for focusing and imaging, the camera lens is opened, a framing preview image is acquired in a framing range of the camera lens according to preset shooting parameters, and the framing preview image can be displayed in the display unit.
For example, in the focusing imaging apparatus 10 shown in fig. 1, the acquisition module 101 may further include a propagation wave distance measuring sensor, such as an ultrasonic distance measuring sensor or an infrared distance measuring sensor. It is to be understood that the propagating wave may be other propagating waves, and the embodiment is not limited thereto.
For the ultrasonic ranging sensor, the ultrasonic waves emitted by the ultrasonic ranging sensor need to satisfy the view range of the camera lens in the acquisition module 101, i.e., the lens field angle of the camera lens.
Specifically, since ultrasonic waves are elastic mechanical waves that vibrate longitudinally, they propagate by virtue of molecular motion of a propagation medium. Thus, the wave equation description for ultrasonic waves is similar to that for electromagnetic waves, as shown in equation 1:
wherein A (x) is amplitude, A0Is a constant, w is the circular frequency, t is the time, x is the propagation distance of the ultrasonic wave,is the wave number, lambda is the wavelength of the ultrasonic wave, and the attenuation constant α ═ af of the ultrasonic wave2Wherein a is a dielectric constant, and f is the vibration frequency of the ultrasonic wave.
For example, the dielectric constant a of air is 2 × 10-13s2/cm, thereforeWhen the vibration frequency of the ultrasonic wave is f 40kHz, α is 3.2 × 10-4cm-11/α is 31m, and when f is 30kHz, 1/α is 56m, so it can be seen that the higher the frequency of the ultrasonic wave, the more the attenuation is, and the shorter the distance traveled.
In addition, the pointing angle theta of the ultrasonic ranging sensor is the included angle of the ultrasonic wave beam half-power angle, which can directly influence the ranging resolution and is an important technical parameter influencing the ranging precision. Taking a wafer ultrasonic ranging sensor as an example, the size of the pointing angle θ is related to the wavelength λ of the ultrasonic wave of the wafer ultrasonic ranging sensor and the radius r of the wafer ultrasonic ranging sensor, and the specific relationship is as shown in formula 2:
as can be seen from equation (2), the smaller the pointing angle θ of the ultrasonic ranging sensor is, the higher the spatial resolution is, the larger the radius r of the wafer ultrasonic ranging sensor is required to be. When f is 40kHz, one can obtain: the wavelength λ of the ultrasonic wave is 340/40000 mm, where C represents the propagation speed of the ultrasonic wave in air. In this case, in the present embodiment, the vibration frequency of the ultrasonic wave is preferably set to f 40kHz, based on the correspondence relationship between the pointing angle θ of the ultrasonic distance measuring sensor, the radius r of the wafer ultrasonic distance measuring sensor, and the wavelength λ of the ultrasonic wave, which is expressed by equation (2).
Therefore, the acquisition module 101 may specifically acquire the coordinate information corresponding to the object information by using an ultrasonic sensor according to the ultrasonic wave with the frequency of 40KHz in the viewing range of the imaging lens.
For the infrared sensor, since the pointing angle of the infrared ray is much smaller than that of the ultrasonic wave, one infrared ray beam can only measure an object in a single direction or at a single angle, and therefore, if coordinate information of an object in the viewing range of the camera lens is to be collected, the infrared sensor needs to measure multiple infrared rays, and therefore, the collection module 101 needs to collect the coordinate information corresponding to the object information by using the infrared sensor through multiple infrared rays with the same frequency and different emission angles in the viewing range of the camera lens.
For example, in the device 10 for focused imaging shown in fig. 1, the distance between the object in the preview image and the camera lens of the acquisition module 101 may be obtained by the difference between the emission time of the propagating wave and the receiving time of the propagating wave echo.
Further, when the propagation wave is an ultrasonic wave, accordingly, the distance L between the object in the preview image and the camera lens of the acquisition module 101 can be obtained by equation (3):
wherein, T is a transit time, which is a time for the ultrasonic wave emitted from the ultrasonic wave emitting end to propagate to the ultrasonic wave receiving end through the gas medium. It can be understood that, as shown in fig. 3, when the ultrasonic ranging sensor employs a remote pulse reflection type to measure the distance between the object in the preview image and the camera lens of the capture module 101, the distance is half of the sound wave transmission distance. It can be understood that, when the propagation wave is infrared, the distance is obtained in the same manner as above, and will not be described again.
For example, in the focusing imaging apparatus 10 shown in fig. 1, the view preview image generated by the capture module 101 may be displayed by a display unit with touch sensing, and when the selection module 102 receives a second instruction of a user to select an object in the displayed preview image, the first object information in the preview image is selected according to the selection instruction of the user.
Specifically, referring to fig. 4, the processing module 103 includes: a ranging sub-module 1031, a selection sub-module 1032, and a focusing sub-module 1033, wherein,
the distance measuring submodule 1031 is configured to determine a first distance between the first object and the camera lens according to the coordinate information corresponding to the first object information; and the number of the first and second groups,
determining a second distance between a second object except the first object and the camera lens according to the coordinate information of the second object in the image information;
a selecting submodule 1032, configured to select a target object with a second distance that is the same as the first distance from the second object;
the focusing sub-module 1033 is configured to perform focusing processing on the first object and the target object in the preview image to obtain a focused image.
Preferably, the distance between the target object and the camera lens of the acquisition module 101 is equal to the distance between the selected first object and the camera lens of the acquisition module 101, so that the target object and the selected first object are in a uniform plane, and the focusing sub-module 1032 can focus on the scene in the uniform plane.
Further, the area range of the unified plane can also be set and determined by the user's requirement, and therefore, the apparatus 10 further includes a determining module 104 for receiving a third instruction to determine the selected area;
accordingly, the selecting sub-module 1032 is configured to select a target object with a second distance equal to the first distance from the second object located in the selected area.
Further, in the process of obtaining the focused image, the focusing sub-module 1033 may be further configured to perform non-focusing processing on an object in the preview image, which is not in the same plane as the selected object, other objects in the preview image, other than the first object and the target object, for example, image processing such as image sharpening, blurring, color rendering, and the like, so as to achieve an effect of blurring the aperture of the camera lens. It is to be understood that the focus sub-module 1033 may also set the degree of blurring.
The present embodiment provides a device 10 for focusing and imaging, which uses a propagation wave to replace a conventional auxiliary camera lens to measure the distance between a main camera lens and a shot object, so as to avoid the influence of external light and still collect the distance between the main camera lens and the shot object under the condition of low illuminance.
