The application layer comprises the following steps: the device comprises a storage space acquisition module, a resource management module and an image acquisition module; the framework layer comprises a storage state manager and an information storage module. Specifically, the storage space acquisition module is mainly used for recording the current available storage space of the display device, so that the controller can control the display of the display device to display prompt information when determining that the available storage space is smaller than the preset threshold according to the size relation between the available storage space and the preset threshold, wherein the prompt information is used for prompting a user; the resource management module is mainly used for storing and operating local resources, for example, deleting, replacing or exporting some resources to a target device, and the target device can be a usb disk, a server or a cloud, which is not particularly limited in this embodiment; the image acquisition module is mainly used for performing operations such as image shooting, video recording, parameter adjustment and the like; the storage state manager (Storage Stats Manager) is a storage space inquiring and managing function supported by an Android system, and through the logic, the display equipment can determine the use condition of the storage space of the whole machine at present; the information storage module is a Camera (Camera) function of the Andorid system and is mainly used for adjusting resolution, quality values and the like, and meanwhile, the relevant information of the image acquisition module is stored in the information storage module.

For a more detailed description of the image capturing solution in the present disclosure, the following description will be given with reference to fig. 5A by way of example, and it will be understood that the steps involved in fig. 5A may include more steps or fewer steps when actually implemented, and the order between these steps may also be different, so as to enable the image capturing method provided in the embodiments of the present disclosure, which are not limited.

Fig. 5A is a flowchart of an image capturing method according to some embodiments of the present disclosure. The present embodiment is applicable to an explanation of an image acquisition process when the available memory space of the display device is insufficient. As shown in fig. 5A, the image acquisition method specifically includes the following steps:

and S510, controlling the display to display prompt information when the available storage space of the display device is determined to be smaller than a preset threshold value.

The prompt information is used for prompting a user whether to start a memory saving mode or not. The memory-saving mode can be understood as a mode in which the size of the acquired image is reduced by reducing the resolution of the image acquisition module, thereby avoiding a failure in photographing due to insufficient available storage space of the display device. The switch for saving the memory mode can be configured in the display device so that a user can start the operation for saving the memory mode.

Specifically, the controller of the display device can obtain the use condition of the storage space of the display device, and when the available storage space of the display device is determined to be smaller than the preset threshold according to the use condition, the problem that the available storage space of the display device is insufficient and shooting failure possibly occurs is described, at this time, the display of the display device is controlled to display prompt information, and a user is prompted through the prompt information, so that the user determines whether to start the memory saving mode.

S520, responding to the operation of starting the memory saving mode, and reducing the resolution of the image acquisition module from the first value to the second value.

The image acquisition module may be a device with an image acquisition function in a display device, such as a camera or a video camera. The first value is a resolution value supported by the image acquisition module, for example 1920×1080, and may also be other values, which are not limited in this embodiment. The second value is a resolution value supported by the image acquisition module, for example 864×480, but may be another value, which is not limited in this embodiment. The number of resolution values supported by the image acquisition module is usually at least two, for example, the number of resolution values supported by a certain camera may be: 800 x 600, 864 x 480, 1024 x 576, 1680 x 896 and 1920 x 1080, 1920 x 1080 have the highest resolution, 800 x 600 has the lowest resolution.

When the user performs the operation of starting the memory saving mode in a mode of mobile equipment, control equipment or voice and the like, the controller of the display equipment responds to the operation after receiving the operation, and the resolution of the image acquisition module is reduced from a first value to a second value. Specifically, the second value may be determined by the controller or may be set by the user, which is not limited in this embodiment.

In some embodiments, optionally, the aspect ratio of the first value is equal to the aspect ratio of the second value.

In this embodiment, since the resolution is composed of a wide and a high, when the aspect ratio of the first value and the aspect ratio of the second value are equal, it can be ensured that the acquired picture is not stretched and deformed after the resolution is adjusted down, and black edges are not appeared on the upper and lower sides or on the left and right sides, thereby being beneficial to improving the use experience and satisfaction of the user.

In some embodiments, the second value may be optionally set by the user, so the aspect ratio of the first value and the aspect ratio of the second value may also be unequal, which is not limited in this embodiment.

S530, controlling the image acquisition module to acquire the image with the resolution corresponding to the second value.

After the resolution of the image acquisition module is reduced from the first value to the second value by the controller of the display device, the image acquisition module is controlled to acquire the image with the resolution corresponding to the second value, so that the size of the image acquired at the moment can be reduced, the storage space occupied by the image acquired at the moment is reduced, and the normal use of the image acquisition module can be ensured.

In some embodiments, when the first value is 1920×1080, the size of the obtained picture is 511KB when the resolution is used to perform image acquisition on a scene, and when the second value is 864×480, the size of the obtained picture is 115KB when the resolution is used to perform image acquisition on the same scene, so it is known that the size of the picture can be reduced by 4 times after the resolution of the image acquisition module is reduced in the above manner. Particularly, the effect is remarkable when the file obtained when the image acquisition is performed at the resolution corresponding to the first value is large.

According to the image acquisition method provided by the embodiment of the disclosure, when the controller of the display device determines that the available storage space of the display device is smaller than the preset threshold value, the controller of the display device controls the display device to display prompt information, wherein the prompt information is used for prompting a user whether to start a memory-saving mode, when an operation for starting the memory-saving mode is received, the resolution of the image acquisition module is reduced from a first value to a second value in response to the operation, the image acquisition module is controlled to acquire an image with the resolution corresponding to the second value.

Fig. 5B is a schematic diagram illustrating an interface when a display provided in some embodiments of the present disclosure displays a prompt message. As shown in fig. 5B, when the controller of the display device determines that the available storage space of the display device is smaller than the preset threshold, the controller controls the display to display a prompt message, where the prompt message is: the available storage space is insufficient, you can choose to save memory mode or manage resources to increase available storage space, and two options available for user selection: saving memory mode and resource management. The resource management is as follows: the memory saving mode is not turned on, which can be understood as managing local resources of the display device, thereby increasing the available storage space of the display device.

In some embodiments, optionally, the method may further specifically include:

before determining that the available storage space of the display device is smaller than a preset threshold value, detecting that an image acquisition module is started, and determining whether a memory saving mode is started;

under the condition that the memory saving mode is started, the resolution of the image acquisition module is reduced from a first value to a second value.

Specifically, before determining that the available storage space of the display device is smaller than a preset threshold, the controller of the display device determines whether the memory saving mode is on if it is detected that the image acquisition module is started. Under the condition that the memory saving mode is started, the controller of the display device reduces the resolution of the image acquisition module from the first value to the second value, so that the subsequent image acquisition module can acquire images with the resolution corresponding to the second value.

In this embodiment, under the condition that the available storage space of the display device is sufficient, if the memory saving mode is turned on, the controller of the display device will reduce the resolution of the image acquisition module from the first value to the second value, so that the image acquisition module can acquire images with the resolution corresponding to the second value, thereby reducing the size of the acquired images, saving the storage space for the display device, and being capable of storing more resources in the display device.

In some embodiments, optionally, when it is determined that the available storage space of the display device is smaller than the preset threshold, the control display displays a prompt message, which may specifically include:

acquiring available storage space of the display equipment through a storage state manager of the display equipment;

and when the available storage space is determined to be smaller than the preset threshold value according to the size relation between the available storage space and the preset threshold value, controlling the display to display prompt information.

Specifically, the storage state manager of the display device has a storage space inquiring and managing function, so that the controller of the display device can acquire the current available storage space of the display device through the storage state manager of the display device, compare the available storage space with a preset threshold value, and control the display to display prompt information when the available storage space is determined to be smaller than the preset threshold value according to the size relation.

In this embodiment, through the above process, it can be determined that the available storage space of the display device is smaller than the preset threshold, and prompt information is provided timely, so that the user can operate subsequently.

Fig. 6A is a flowchart illustrating another image capturing method according to some embodiments of the present disclosure. This embodiment is optimized based on the above embodiment. Optionally, the embodiment may be suitable for explaining an image acquisition process when the memory saving mode is not turned on. As shown in fig. 6A, the image acquisition method specifically includes the following steps:

and S610, controlling the display to display prompt information when the available storage space of the display device is determined to be smaller than a preset threshold value.

S620, controlling the display to display target information of resource management in response to the operation of not starting the memory saving mode.

Wherein, the target information comprises at least one option of deleting, exporting and reducing the picture quality.
