Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
With the progress of technology, electronic devices such as mobile phones have become a necessity for people to live. In the use process of electronic equipment such as mobile phones, taking a picture or taking a picture by using a camera is an important function. When photographing or viewing an image using an electronic device such as a mobile phone, it is generally necessary to enlarge or reduce the image. In the related art, in the process of gradually enlarging or reducing an image, the display variation of the image is uneven, and the visual experience of a user is poor.
In the first aspect, in a scene in which zoom adjustment is used to zoom in or out a preset image in a photographing process, there is a problem in that image variation is uneven.
The camera sensor resolution of the electronic device is gradually increased, and a zoom adjustment (zoom) process is lengthened, so that it is important how to realize the screen display in the zoom adjustment process. There are various screen display modes of the zoom process in the related art. For example, when a zoom adjustment scale line (zoom bar) is manually dragged or a target zoom value is clicked on a shooting interface of the mobile phone, an image of the shooting interface is displayed gradually according to the zoom value in the zoom bar.
It can be seen how the zoom bar is set is a major factor affecting the effect of the camera interface or the image interface gradient. In the related art, depending on the zoom capabilities of different lens modules in a camera, the zoom bar often includes a plurality of zoom intervals with different specifications, such as a zoom interval of an ultra-wide angle lens, a zoom interval of a telephoto lens, a zoom interval of an ultra-telephoto lens, etc., and in combination with the characteristics of each lens module, the focal length values or the set standards of each set zoom interval are very different.
The focal length scales in each zoom interval may be evenly distributed (in an arithmetic progression), and when a user drags zoom bar or clicks on a target value, it is possible to span different zoom intervals during the gradual change according to the continuous focal length value, resulting in a different and uneven effect on the visual display. Each zoom interval may be manually adjusted, but the manual adjustment may have a defect of individual variability, or may have a phenomenon of uneven display.
In the second aspect, there is also a problem in that the image change is not uniform when the image is viewed by a mobile phone.
For example, when viewing an image in an album, a two-finger slide may zoom in or out the image. According to the double finger sliding, the electronic device can cut the image. In the cutting process, the problem of uneven zoom-in or zoom-out variation also exists, and along with the promotion of pixels, double-finger multiple zoom-in or zoom-out is required when processing high resolution or exceeding resolution to reach the target cutting state.
In order to solve the above technical problems, the present disclosure provides an image display method, which is applied to an electronic device, and the method includes: and responding to the operation information on the preset interface, and acquiring a corresponding target adjustment value in the adjustment scale. And adjusting the display effect of the preset image in the preset interface according to the target adjustment value. By using the method disclosed by the invention, in a scene involving zoom-in and zoom-out adjustment in the process of photographing or viewing pictures, a preset image can be changed step by step from the current state according to the adjustment value of the scale in the middle of the adjustment scale until the state corresponding to the target adjustment value. In the process of gradually changing according to the scale of the equal proportion, the level or the interval with larger phase difference cannot be directly crossed, so that gradual change display of the image is more uniform and smooth.
In an exemplary embodiment, the image display method of the present embodiment is applied to an electronic device having a camera module, where the electronic device may be, for example, an electronic device having a photographing function or a picture viewing function, such as a mobile phone, a notebook computer, a tablet computer, and a smart watch.
As shown in fig. 1, the method of this embodiment specifically includes the following steps:
s110, responding to operation information on a preset interface, and acquiring a corresponding target adjustment value in an adjustment scale.
S120, according to the target adjustment value, adjusting the display effect of the preset image in the preset interface.
In step S110, the preset interface may include, for example, a preview interface or an image viewing interface of the camera application. The regulating scale (boom bar) comprises a plurality of regulating values (boom values) which are arranged step by step in an equal proportion order, wherein each regulating value can be regarded as a stage. The operation information of the user on the preset interface may include a sliding, clicking or double-finger sliding operation. For example, according to the operation information of the user, the CPU of the electronic device may learn the target adjustment value; for another example, the camera application or the image viewing application may determine a target adjustment value for image adjustment based on the operation information of the user, and transmit the target adjustment value to a CPU (such as an AP in the CPU) of the electronic device.
In step S120, the display effect includes: the preset image is changed from the current state to the state corresponding to the target regulating value step by step according to the scale regulating value in the regulating scale. In this embodiment, in the process of gradual change according to the scale with equal proportion, the scale cannot directly span the level or the interval with larger phase difference, so that in the adjustment process, the zoom interval or the scaling interval with larger specification change cannot be spanned when the image is changed and displayed, and the gradual change display effect is more uniform and smooth.
In an exemplary embodiment, as shown in fig. 2, the method of the present embodiment may further include the steps of:
s104, determining an adjusting scale according to the preset zoom parameter and the preset model.
In this embodiment, the CPU of the electronic device determines the adjustment scale with unified setting standard according to the preset zoom parameter and the preset model, instead of distinguishing the zoom interval according to different lens modules. The preset model may be, for example, an exponential model. The preset zoom parameter may be set according to actual needs, or may be set according to the zoom capability of the electronic device.
In an exemplary embodiment, still referring to fig. 2, the method of this embodiment further comprises the steps of:
s102, acquiring preset zoom parameters.
In this embodiment, the preset zoom parameters may include, for example, a first preset zoom parameter and a second preset zoom parameter. The first preset zoom parameter is used for representing a maximum zoom value (zoom Max) of the camera module (including all lens modules), and the second preset zoom parameter is used for representing a minimum zoom value (zoom Min) of the camera module. The maximum zoom value (zoom max) may refer to the maximum zoom capability in all lens modules of the electronic device camera module.
In this embodiment, as shown in fig. 3, step S104 may specifically include the following steps:
s1041, determining the number of scales in the adjusting scale according to preset zoom parameters.
S1042, determining the magnitude of any adjusting value in the adjusting scale according to a preset model.
In step S1041, the first preset zoom parameter may be an upper limit of the adjustment scale, and the second preset zoom parameter may be a lower limit of the adjustment scale. And determining the number of scales in the adjusting scale according to the first preset zooming parameter and the second preset zooming parameter, namely according to the upper limit and the lower limit of the adjusting scale. Wherein each scale corresponds to an adjustment value, such as a first scale corresponds to a minimum zoom value (zoom min) and a last scale corresponds to a maximum zoom value (zoom max).
For example, as shown in fig. 4, the number of scales may be determined using the following steps:
s1041-1, determining the updated frame number of the image between the second preset zoom parameter and the first preset zoom parameter, and marking n.
In this step, the frame number should be adapted to the frame rate of the electronic device camera, for example, the frame output frame rate of the camera sensor is 30fps when taking a photograph and previewing, in order to adapt the frame number to the frame rate, the frame number n may be determined or set to 30, so as to increase the speed of displaying the image, and ensure that the duration of the process of displaying 30 frames of image is not excessively long (in this embodiment, the display duration is one second).
S1041-2, determining the number of scales corresponding to the frame number according to the frame number.
In the step, the number of scales corresponds to the number of frames, and the number of scales can be set to be (n+1), namely, the number of scales on the adjusting scale can be from 0,1 to … … to n, and the number of scales is (n+1); the adjustment values corresponding to the scales one by one respectively may be (n+1) in total from zoomin to zoomax. It will be appreciated that the image is adjusted by zoomMin to zoomMax to co-require that n frames be experienced or updated.
In step S1042, the adjustment values in the adjustment scale constitute an equal-ratio array, i.e. the ratio of each adjustment value to its immediately preceding one is fixed. According to the exponential model, the magnitude of any one of the adjustment values can be determined one by one.
For example, when the number of frames between zoomax and zoomin is n and the ratio of adjacent adjustment values is B, then:
zoomMax＝zoomMin*B n ，
for the adjustment value zoomN corresponding to the nth scale, the index model may be learned:
according to the index model, the magnitude of any adjustment value can be obtained.
In an exemplary embodiment, when the operation information includes a sliding operation in a preset direction of the adjustment scale, such as an upward sliding operation as shown in fig. 5; the method of this embodiment, as shown in fig. 6, may include the following steps:
s210, determining an adjusting scale according to a preset zoom parameter and a preset model.
S220, responding to the operation information on the preset interface, and acquiring a plurality of sequentially adjacent adjustment values corresponding to the path of the sliding operation as target adjustment values.
S230, controlling the image in the preset interface to be adjusted from the current state to zoom states corresponding to a plurality of sequentially adjacent adjusting values step by step.
Step S210 is the same as step S110, and will not be described here again.
In the above-described exemplary embodiments, in the preview interface of the photographed image or in the image viewing interface, the user slides up on the adjustment scale to enlarge the preview image; or, in the preview interface of the photographed image or in the image viewing interface, the user slides down on the adjustment scale to zoom out the preview image.
For example, in step S220, a scene in which a focal length is adjusted during photographing may be involved. In the preview interface of the camera, the application layer may determine a zoom value through which the sliding path passes, and a zoom value corresponding to when the sliding operation is stopped, and report the zoom value to the CPU of the electronic device, that is, the target adjustment value obtained in this step includes a plurality of adjustment values that are arranged in sequence.
In step S230, according to the obtained target adjustment values, the preset image is gradually enlarged or reduced from the current state to the state corresponding to each adjustment value according to the order of the sliding path until the state corresponding to the final target adjustment value is reached.
In an exemplary embodiment, when the operation information includes a click operation on the adjustment scale as shown in fig. 7, the method of this embodiment may include the following steps as shown in fig. 8:
s310, determining an adjusting scale according to a preset zoom parameter and a preset model.
S320, responding to the operation information on the preset interface, and determining an adjustment value corresponding to the clicking operation as a target adjustment value.
S330, determining a first adjusting interval formed by a plurality of adjusting values which are sequentially adjacent between the current zoom value corresponding to the current state and the target adjusting value. And controlling the preset image in the preset interface to be adjusted step by step from the current state to the state corresponding to each adjusting value in the first adjusting interval.
Step S310 is the same as step S110, and will not be described here again.
In the above-described exemplary embodiments, in the preview interface of the captured image or in the image viewing interface, the user performs clicking on the adjustment scale to achieve image state adjustment of the preset image.
For example, in step S320, a scene in which a focal length is adjusted during photographing may be involved. For example, in the shooting preview interface, the user clicks on the adjustment scale, and the electronic device determines that the corresponding zoom value is the target adjustment value.
In step S330, in the adjustment process of the present embodiment, after determining the target adjustment value, the first adjustment interval is determined with the current adjustment value corresponding to the current state as the lower limit and the target adjustment value as the upper limit. And determining each adjusting value in the first adjusting interval according to the index model, and controlling the preset image in the preset interface to be adjusted step by step from the current state to the state corresponding to each adjusting value in the first adjusting interval.
It will be appreciated that the adjustment may be performed a plurality of times in this embodiment, and that the current zoom value may be the target adjustment value of the last adjustment in one adjustment. And determining a new target adjustment value by clicking again, namely the current zoom value adjusted at the time is zoomN0, and marking the new target adjustment value as zoomT. A new first adjustment interval is formed between the current zoom value zoomN0 and the new target adjustment value zoomT. In determining each adjustment value zoomN in the new first adjustment interval, the above-mentioned exponential model may still be used, namely:
wherein N, T, N represents a scale between 0 and n.
In an exemplary embodiment, when the operation information includes a two-finger zoom operation at a preset interface, such as a two-finger slide zoom operation as shown in fig. 9. The method of this embodiment is shown in fig. 10, and includes the following steps:
S410, determining an adjusting scale according to a preset zoom parameter and a preset model.
S420, acquiring a sliding distance of the double-finger zooming operation; and determining a second adjusting section as a target adjusting value according to the sliding distance.
S430, controlling the image in the preset interface to be adjusted step by step from the current state to the zooming state corresponding to each adjusting value in the second adjusting interval.
Step S410 is the same as step S110, and will not be described here again.
For example, in step S420, a scene for enlarging or reducing an image in the process of performing picture viewing or shooting picture preview in the image viewing interface may be involved, or a scene for enlarging or reducing an image in the process of performing image zooming in the preview interface may also be involved.
According to the sliding distance of the double finger in the operation shown in fig. 9, it is equivalent to the second adjustment section in the adjustment scale. For example, the two directions slide in opposite directions to enlarge the image; or a bi-directional opposite direction for zooming out the image.
Step S420 may specifically include: s4201, acquiring configuration information.
