Problems solved by technology

[0003] However, the continuous shooting speed of the existing shooting devices is relatively slow, generally difficult to exceed 5 frames per second, and cannot accurately capture the motion details of moving objects
The reason is that the existing photographing device includes an imaging element and a data processing unit. The imaging element captures the subject to generate a piece of image data, and the data processing unit needs to decode, encode, and compress the image data in a series of later stages. After processing and storing, the camera element can take the next picture, so it consumes a lot of time and slows down the continuous shooting speed
The speed of image data collection by the camera element itself is extremely fast, but the speed of image data processing by the data processing unit is relatively slow, which seriously limits the shooting speed of the camera element.
In addition, the user cannot set or choose the continuous shooting speed, and the system defaults to continuous shooting with its maximum ability, which is poor in controllability
resulting in poor user experience

[0038] see image 3 , the first embodiment of the shooting method of the shooting device of the present invention is proposed, and the shooting method includes the following steps:

[0039] Step S101 , photographing the subject continuously, and generating image data.

[0040] When the photographing device is in the continuous shooting mode, it continuously photographs the subject and generates image data.

[0041] Step S102, the cache unit caches the image data.

[0042] The buffer unit only buffers the image data generated by the continuous shooting of the subject by the shooting device, but does not process the image data. Therefore, the continuous shooting speed of the shooting device only depends on the buffer space of the buffer unit. Therefore, it can be expanded by expanding the buffer unit Buffer space to maximize the continuous shooting speed of the camera. The size of the cache space of the cache unit is determined by the memory size of the photographing device, ...

[0046] see Figure 4 , propose the second embodiment of the shooting method of the shooting device of the present invention, the shooting method includes the following steps:

[0047] Step S201, setting the cache speed of the cache unit.

[0048] In this embodiment, the purpose of directly controlling the continuous shooting speed of the photographing device is achieved by adjusting the buffering speed of the buffering unit to buffer the image data.

[0049] Step S202, continuously photographing the subject, and generating image data.

[0050] Step S203, the cache unit caches the image data according to the set cache speed.

[0051] The speed at which the buffer unit caches image data directly determines the continuous shooting speed of the shooting device.

[0052] Step S204, read the image data from the cache unit, and process the image data.

[0053] Therefore, the shooting method of this embodiment allows the continuous shooting speed to be preset according to user nee...

Abstract

The invention discloses a shooting device and a shooting method thereof. The shooting device comprises a camera shooting component, a cache unit and a data processing unit, wherein the camera shooting component is used for shooting an object to be shot continuously and generating image data, the cache unit is used for caching of the image data, and the data processing unit is used for reading the image data from the cache unit and processing the image data. According to the shooting device and the shooting method thereof, an image data acquisition thread and an image data processing thread are mutually independent, the speed of image acquisition of the camera shooting component is prevented from being influenced by the data processing unit with a low speed, the fast image acquisition potentiality of the camera shooting component is released, fast continuous shooting is achieved, and image details of a moving object at every moment can be obtained through the fast continuous shooting; in addition, a user can set the caching speed of the cache unit or the processing mode of the data processing unit to adjust the continuous shooting speed of the shooting device, and therefore the controllability of the shooting device is improved and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of photographing, in particular to a photographing device capable of rapid continuous photographing and a photographing method thereof. Background technique [0002] Existing shooting devices such as digital cameras have a continuous shooting function. The so-called continuous shooting refers to continuous shooting, which means that the normal shooting process is continuously executed, similar to the process of simulating the user's continuous clicking of the camera button, so that the details of the movement of the moving object can be captured. . [0003] However, the continuous shooting speed of the existing shooting devices is relatively slow, generally difficult to exceed 5 frames per second, and cannot accurately capture the motion details of moving objects. The reason is that the existing photographing device includes an imaging element and a data processing unit. The imaging element captures the sub...
