Problems solved by technology

[0003] However, when the object distance is too small, such as less than 40 centimeters (cm), the sharpness of all colors is poor and does not meet the requirements. Even if the full-frame focusing technology corrects the image, the obtained image is still blurred. Clear

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0013] see figure 1 , which discloses a stereo camera device 10 according to a preferred embodiment of the present invention. In this embodiment, the stereo camera device 10 is a mobile phone. The stereo camera device 10 includes two camera modules 21 , 22 , a processor 30 , a display screen 40 , and an output port 50 .

[0014] The two camera modules 21 and 22 are used to take images from different angles of the same object, and send them to the processor 30, and the processor 30 synthesizes them into a stereoscopic image. In order to ensure the effect of stereo shooting, the center distance between the two camera modules 21 and 22 (that is, the distance between the optical axes of the two camera modules) ranges from 25 to 40 millimeters (mm), preferably 32.5 millimeters (mm). Since the stereo camera technology is familiar to those skilled in the art, th...

Abstract

The invention provides a three-dimensional photographic device. The three-dimensional photographic device comprises two camera modules and a processor, wherein each camera module comprises a camera lens unit and an image sensor, the camera lens unit utilizes a shape memory alloy element as a variable focal length actuator, and the image sensor is used for forming images with at least two colors. The processor comprises a full width focusing module, a focusing driving module and an image synthesis module, the full width focusing module is used for judging an object distance according to acutance of colors, judging whether the object distance is larger than a certain preset distance or not, when the object distance is larger than the preset distance, the images are conducted sharpening processing and the images become distinct, otherwise a control signal is sent to the focusing driving module, the camera modules are driven to change a focal distance to directly acquire distinct images after the focusing driving module receives the control signal, and the image synthesis module is used for utilizing the distinct images to synthesize three-dimension images. The three-dimensional photographic device utilizes a full width focusing technology, and therefore the distinct images can be further acquired in a close distance.

Description

technical field [0001] The invention relates to a stereo camera device. Background technique [0002] At present, the wide-frame focusing technology (WDF, Width Depth Field) has been applied in digital photography, which decomposes the image of the object captured by the digital camera module into different colors, such as RGB three primary colors, corresponding to the object distance, different colors With different sharpness curves, the full-frame focusing technology selects the color with the best sharpness in the image, and corrects the sharpness of other colors based on the best sharpness to improve the overall image clarity. The use of full-frame focusing technology does not require the physical focusing process of the camera module, so that clear images can be obtained quickly. [0003] However, when the object distance is too small, such as less than 40 centimeters (cm), the sharpness of all colors is poor and does not meet the requirements. Even if the full-frame f...
