All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.
The following describes the shooting method and the shooting apparatus provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Example one
Referring to fig. 1, specific steps of a shooting method provided in a first embodiment of the present application are shown.
In the embodiment of the application, when a user shoots an image through the shooting terminal, a depth of field selection operation can be executed on the preview image according to an actual shooting requirement, and a first depth of field range of the preview image is determined.
It should be noted that, the depth of field selection operation performed on the preview image by the user may be performed after determining the second depth of field of the preview image, with the second depth of field range as a reference; the first depth of field range may also be determined directly through the depth of field selection operation, for example, when the user performs image capturing with reference to the capturing tutorial, the corresponding first depth of field range may be selected directly through the depth of field selection operation, or the user sets the first depth of field range directly through the depth of field selection operation according to the capturing experience, and so on.
The first depth of field range is a depth of field range corresponding to a target image which is expected to be finally generated by a user, and the second depth of field range is an actual depth of field range of the preview image.
The shooting terminal determines a first depth of field range according to the received depth of field selection operation.
The first image may be an image to be shot, or may be a depth image corresponding to the image to be shot.
The target pixel is an exposure unit in the image sensor. The image sensor comprises a plurality of pixels, the pixels are minimum exposure units in the image sensor, and each pixel corresponds to a depth of field value. Pixels of the image sensor, the depth of field value of which is matched with the first depth of field range, are all target pixels, and the target pixels are exposed, so that a target image with the depth of field range being the first depth of field range can be obtained.
And 104, under the condition that a shooting instruction is received, responding to the shooting instruction, exposing the target pixel, and generating a target image.
After receiving the shooting instruction, the shooting device only carries out exposure processing on the determined target pixel in response to the received shooting instruction, and the generated target image only comprises pixel points with the depth of field values belonging to the first depth of field range due to the fact that the target pixel is matched with the first depth of field range, so that information redundancy in the generated target image is reduced, and the occupancy rate of the target image to a storage space is reduced.
In an optional embodiment of the present application, before the receiving a depth of view selection operation of the user in step 101, the method further includes:
s11, obtaining a depth value corresponding to each pixel point in the first image, and determining a second depth range of the first image.
and S12, matching the second depth of field range of the first image with the first depth of field range, and determining a first pixel point in the first image.
And S13, determining a pixel corresponding to the first pixel point in the image sensor as a target pixel.
In the embodiment of the application, before receiving a depth of field selection operation of a user, a depth of field value corresponding to each pixel point in the first image may also be obtained, where each pixel point corresponds to one depth of field value. After the depth of field values corresponding to the pixel points of the first image are obtained, the second depth of field range of the first image is determined according to the depth of field values of the pixel points in the first image, specifically, the maximum depth of field value and the minimum depth of field value in the depth of field values corresponding to the pixel points can be determined, and the second depth of field range of the first image is determined according to the determined maximum depth of field value and the determined minimum depth of field value.
The second depth of field range is the maximum depth of field range of the first image, and the first image is exposed in the second depth of field range, so that a clear image can be obtained. The second depth of field range of the first image may be acquired using TOF (Time of flight ranging). Specifically, after focusing the shooting subject in the first image according to the received manual focusing operation or by adopting an automatic focusing mode, the shooting device acquires parameters such as the diameter of the allowable circle of confusion, the focal length of the lens, the shooting aperture of the lens, the focusing distance and the like of the first image, and then calculates the depth of field of the first image according to the acquired parameters such as the diameter of the allowable circle of confusion, the focal length of the lens, the shooting aperture of the lens, the focusing distance and the like. Of course, other distance measuring means may also be adopted to obtain the second depth of field range of the first image, and the embodiment of the present application is not particularly limited.
And after the second depth of field range of the first image is determined, matching the second depth of field range with the first depth of field range determined according to the depth of field selection operation of the user, and determining that the intersection of the first depth of field range and the second depth of field range is the target depth of field range. For example, assume that the first depth of field is [ a1, a2], the second depth of field is [ b1, b2], if a1< b1< b2< a2, then the target depth of field is [ b1, b2]; if a1< b1< a2< b2, the target depth of field range is [ b1, a2]. The first pixel point in the first image is the pixel point of which the depth of field value belongs to the target depth of field range.
After the first pixel point in the first image is determined, a target pixel in the image sensor is further determined according to the first pixel point, and the depth of field range corresponding to the target pixel is matched with the depth of field range corresponding to the first pixel point. Each pixel in the image sensor corresponds to a depth of field value, the pixel is exposed, pixel points with the depth of field values matched with the depth of field values corresponding to the pixel can be obtained, the target pixel is exposed, second pixel points with the depth of field values matched with the depth of field values of the first pixel points can be obtained, and the second pixel points form a target image.
In an optional embodiment of the present application, after the obtaining of the depth of field value corresponding to each pixel point in the first image in step S11, the method further includes:
step S21, marking each pixel point according to the depth value of each pixel point in the first image to obtain a depth information image of the first image, wherein the pixel points with the same depth value in the depth information image are marked with the same identification information.
And S22, displaying the depth information map.
and step S23, receiving the depth of field selection operation of the depth of field information map.
The step 102 of determining a first depth of field range according to the depth of field selection operation includes:
and step S24, determining a first depth of field range according to the depth of field selection operation of the depth of field information map.
In this embodiment of the application, after obtaining the depth of field value corresponding to each pixel point in the first image, each pixel point may be further marked according to the depth of field value of each pixel point in the first image, specifically, each pixel point corresponds to one depth of field value, one depth of field value generally corresponds to a plurality of pixel points, and the same mark may be used for the pixel points with the same depth of field value, or the same mark may be used for the pixel points with the same depth of field value belonging to the same depth of field range. After each pixel point in the first image is marked, a depth information map of the first image is generated according to the marking result, and the depth information map is displayed for a user. Optionally, the depth information map may be displayed in a three-dimensional stereo image manner, where in the depth information map, one depth value corresponds to one depth plane, and pixel points in one depth plane have the same mark. It can be understood that a plurality of pixel points in the depth plane corresponding to one depth value are equivalent to image slices of the first image, image slices corresponding to each depth value in the depth range of the first image constitute the first image, and the image slices corresponding to different depth values have different detail features of the first image. The user can determine the first depth of field range to be selected through the detail features displayed by the image slices corresponding to the depth of field values in the depth of field information map. Therefore, a depth of field selection button can be provided on the display interface of the depth of field information map of the first image, and the user can determine the first depth of field range in real time by performing a depth of field selection operation in the process of viewing the depth of field information map of the first image.
In an optional embodiment of the present application, after the obtaining, in step S11, a depth-of-field value corresponding to each pixel point in the first image, and determining a second depth-of-field range of the first image, the method further includes:
step S31, displaying a depth-of-field axis corresponding to the first depth-of-field range, where the depth-of-field axis includes depth values from a minimum depth value to a maximum depth value of the first depth-of-field range.
and step S32, receiving a first depth of field value and a second depth of field value selected by the user in the depth of field axis.
The step 102 of determining a first depth of field range according to the depth of field selection operation includes:
and step S33, determining a first depth of field range according to the first depth of field value and the second depth of field value.
In the embodiment of the application, after the second depth of field range of the first image is acquired, a depth of field axis corresponding to the second depth of field range may be displayed on a preset operation interface, so that a user may select the first depth of field range. Specifically, each depth value from the minimum depth value to the maximum depth value of the second depth range is displayed on the depth axis corresponding to the second depth range, and the user may select any two depth values on the depth axis corresponding to the second depth range through a dragging operation, for example, a depth culling box is displayed on the depth axis corresponding to the second depth range, both left and right frames of the depth culling box may be dragged, the depth value corresponding to the left frame on the depth axis is recorded as the first depth value, and the depth value corresponding to the right frame on the depth axis is recorded as the second depth value, so that the first depth value and the second depth value selected by the user may be determined according to the dragging operation of the user on the depth culling box. After determining the first and second user-selected depth of view values, the user-selected first depth of view range may be determined. Taking the depth of field culling box existing on the depth of field axis corresponding to the second depth of field as an example, generally, the depth of field values on the depth of field axis are arranged from left to right in the order from small depth of field value to large depth of field value, therefore, in the first depth of field value and the second depth of field value determined according to the pushing operation of the user on the depth of field culling box, the first depth of field value is smaller than the second depth of field value, the first depth of field value is used as the minimum value of the first depth of field range, the second depth of field value is used as the maximum value of the first depth of field range, and thus, the first depth of field range can be determined according to the first depth of field value and the second depth of field value.
Two depth of field value adjusting buttons may also be provided on the preset operation interface, and referring to fig. 2, a schematic view of the preset operation interface of the shooting device according to the embodiment of the present application is shown, where in the preset operation interface, two depth of field value adjusting buttons are provided, which are an assembly "depth of field 1" and an assembly "depth of field 2" respectively. The minimum of the depth 1 and the depth 2 may be set to be the minimum of the second depth range of the first image, and the maximum of the depth 1 and the depth 2 may be set to be the maximum of the second depth range of the first image. Respectively initializing the depth of field 1 and the depth of field 2, setting the initial value of the depth of field 1 as the minimum value of the second depth of field range of the first image, and setting the initial value of the depth of field 2 as the maximum value of the second depth of field range of the first image. When the user determines that the shooting mode is the 'selectable depth of field shooting', the user can adjust the values of the depth of field 1 and the depth of field 2 in the preview operation interface, determine a first depth of field value according to the value of the depth of field 1 finally determined by the user, determine a second depth of field value according to the value of the depth of field 2 finally determined by the user, and determine a first depth of field range according to the first depth of field value and the second depth of field value.
It should be noted that, in the embodiment of the present application, the first depth value and the second depth value may also be depth interval values, and the user determines one or more depth value intervals through a depth selection operation, and determines the first depth range according to the determined one or more depth value intervals. That is to say, in the embodiment of the present application, the first depth-of-field range may be a continuous interval, or may be composed of multiple sub-intervals, and the specific first depth-of-field range is determined according to the depth-of-field selection operation of the user as long as the shooting requirement of the user can be met.
In an optional embodiment of the present application, after the matching the second depth-of-field range of the first image with the first depth-of-field range, and before determining the first pixel point in the first image, and before receiving the shooting instruction, the method further includes: generating a preview image according to the first pixel point; and displaying the preview image.
The essence of the image is the combination of the pixel points corresponding to different depth of field values, and therefore, in the embodiment of the present application, after the first pixel point in the first image is determined according to the first depth of field range and the second depth of field range, and before the shooting instruction is received, the preview image can be generated according to the first pixel point. As shown in fig. 2, in the process of adjusting the value of the depth of field 1 and the value of the depth of field 2 by the user, a first depth of field range and a first pixel point of the first image may be determined in real time, a preview image is generated according to the first pixel point, and the generated preview image is displayed in an image display area of the preset operation interface.
In the embodiment of the present application, the preview image only includes the first pixel point. Specifically, the pixel points in the first image except the first pixel point can be deleted to obtain a preview image, and the preview image is displayed, so that a user can check the image effect of the target image to be generated in real time through the preview image after determining the first depth of field range, and if the user is not satisfied with the image effect corresponding to the current first depth of field range, the first depth of field range can be readjusted before executing a shooting instruction on the shooting device, so that the first depth of field range is prevented from being readjusted when the shooting effect is found to be not satisfied with expectations after the shooting is finished, the shooting is carried out again, and the image shooting efficiency is improved.
In summary, in the embodiment of the present application, the first depth of field range is determined according to the received depth of field selection operation, and only the target pixel corresponding to the first depth of field range in the image sensor is exposed, so that information redundancy in the generated target image is reduced, and the occupancy rate of the target image to the storage space is reduced.
In the shooting method provided by the embodiment of the present application, the execution subject may be a shooting device, or a control module in the shooting device for executing the shooting method. In the embodiment of the present application, a shooting method executed by a shooting device is taken as an example, and the shooting method provided in the embodiment of the present application is described.
