The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or jerky movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100.

For example, the alarm unit 153 may provide an output in the form of vibration, and when a call, a message, or some other incoming communication (communicating communication) is received, the alarm unit 153 may provide a tactile output (i.e., vibration) to inform the user thereof. By providing such a tactile output, the user can recognize the occurrence of various events even when the user's mobile phone is in the user's pocket. The alarm unit 153 may also provide an output notifying the occurrence of an event via the display unit 151 or the audio output module 152.

The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or will be output.

Based on the above hardware structure of the mobile terminal and the electrical structure diagram of the camera, various embodiments of the device and method of the present invention are provided.

The invention provides a time-gradient image shooting device.

Referring to fig. 3, fig. 3 is a block diagram of a time-gradient image capturing apparatus according to a first embodiment of the present invention. The device comprises:

a setting module 10, configured to set a unit shooting size of the time-gradient image along a preset shooting direction and a shooting period corresponding to the unit shooting size;

in this embodiment, the shooting of the time-gradient image is realized through the mobile terminal, wherein the mobile terminal includes a smart phone, a tablet computer and other devices having a shooting function. Taking a smart phone as an example for explanation, the application scenario of this embodiment may be: the user wants to shoot an image which changes along with time change, namely the time gradient image, at the moment, the user opens a camera function on the mobile phone, selects a time gradient image shooting mode and enters a time gradient image shooting interface, the user sets related parameters on the time gradient image shooting interface, then selects a shooting object and a shooting visual angle, fixes the camera and starts a shutter, and shooting the time gradient image is carried out.

Specifically, the setting module 10 may receive a setting instruction of a user, and set a unit shooting size of the time-gradient image along a preset shooting direction and a shooting period corresponding to the unit shooting size according to the setting instruction of the user, optionally, the user may set the unit shooting size set this time and the shooting period corresponding to the unit shooting size as default values, and the user may use the default values when shooting the time-gradient image next time without repeatedly performing the setting.

In this embodiment, the shooting direction may be determined by a holding state of the mobile terminal, and is specifically divided into two types: the first is the horizontal direction of the mobile terminal in the transverse holding state, and the first is the horizontal direction of the mobile terminal in the vertical holding state. The user can set different unit shooting sizes and shooting periods according to different shooting directions, for example, if the user is currently holding the mobile terminal horizontally for shooting, the pixel capacity in the horizontal direction is larger, so that the unit shooting size value can be set larger, and if the user is currently holding the mobile terminal vertically for shooting, the pixel capacity in the horizontal direction is smaller, so that the unit shooting size value can be set smaller.

It should be noted that the unit of the unit shooting size set by the user may be a distance, such as 1cm, or a pixel, such as 200 pixels; meanwhile, for facilitating subsequent calculation, when the unit shooting size is a distance, the mobile terminal can convert the distance into pixels according to the shooting pixels of the camera and the size of the display screen of the mobile terminal.

After setting the unit shooting size, the user sets the shooting period according to actual needs, for example, the shooting period may be set to 10 minutes, 30 minutes, 1 hour, 1 day, and so on. Of course, the shooting direction may not be determined by the holding state of the mobile terminal, for example, the user may set a default shooting direction of the time-gradient image, for example, if the mobile terminal is in the horizontal direction in the horizontal holding state, the time-gradient image will be shot along the default shooting direction, and the setting may be flexible in implementation.

After the unit shooting size and the shooting period in the preset shooting direction are set, the mobile terminal can shoot the time-gradient image from left to right along the preset shooting direction according to the set unit shooting size and the set shooting period.

The dividing module 20 is configured to obtain shooting pixels of a camera of the mobile terminal, and divide the obtained shooting pixels into a plurality of pixel groups according to the unit shooting size;

in this step, the dividing module 20 acquires the shooting pixels of the local camera, and then divides the acquired shooting pixels into a plurality of pixel groups according to the set unit shooting size.

For example, the shooting pixels of the mobile terminal camera are 500 ten thousand pixels, that is, the resolution is 2560 × 1920, and the set unit shooting size is 256, at this time, the shooting pixels of the camera can be divided into 10 pixel groups, each pixel group is 256 × 1920, and the 10 pixel groups are arranged from left to right along the shooting direction and used as the standard of the subsequent image acquisition.

The acquisition module 30 is configured to, when the mobile terminal receives a shooting instruction, sequentially acquire images on the corresponding pixel groups every other shooting period to obtain a plurality of image columns;

after a user sets a unit shooting size and a shooting period in a preset shooting direction, a shooting key is clicked to start a time gradient image shooting function of the mobile terminal, and when the acquisition module 30 receives a shooting instruction, image acquisition is sequentially performed on corresponding pixel groups according to the shooting period to obtain a plurality of image columns.

Specifically, referring to fig. 4, fig. 4 is a schematic diagram of a shooting process of a time-gradient image in an embodiment of the present invention.
