Embodiment Construction

[0027] In the present invention, by adjusting the imaging process, the main camera of the dual-camera image acquisition device is based on the original imaging process, and the original image file output by the image signal processor is first processed. At this time, the original image file output by the sub-camera will be temporarily stored in the buffer. In the process, after the image signal processor completes the processing of the original image file of the main camera, the temporarily stored original image file of the auxiliary camera is fed back to the image signal processor for processing, and finally the processed dual-camera image is obtained. In this way, the processing of image signals obtained by dual cameras can be supported under the condition of using a single image signal processor.

Abstract

The present invention provides a dual-camera image obtaining device and a camera method thereof. The dual-camera image obtaining device comprises a first camera, a second camera, a first buffer, a second buffer and an image signal processor. The second buffer is coupled with the second camera and is configured to receive and temporarily store original drawing files obtained by the second camera. The image signal processor is coupled with the first camera, the second camera, the first buffer and the second buffer to control the first camera and the second camera to obtain image signals to output a first original drawing file and a second original drawing file and process image signals in the first original drawing file to output a first image to the first buffer, receive the second originaldrawing file temporarily stored in the second buffer from the second buffer after the first image is output and process the image signals in the second original drawing file to output the second image to the first buffer. Therefore, a single-channel image signal processor can support the image signal processing of a dual camera.

Description

technical field [0001] The present invention relates to an image acquisition device and method, and in particular to a dual-camera image acquisition device and an imaging method thereof. Background technique [0002] With the advancement of image acquisition technology, the pixels of digital cameras have increased significantly, but the size of the cameras has been relatively reduced, and can be configured on portable electronic devices such as mobile phones and tablet computers, allowing users to capture images anytime and anywhere. In order to cope with market competition and meet the diverse photography needs of consumers, various manufacturers are committed to improving camera functions to enhance the competitiveness of their products. Among them, in addition to the original camera, in recent years, many devices will be equipped with an additional camera to form a dual camera with the original camera to capture stereoscopic images. In detail, the dual cameras can captur...
