Description

Communication device and its optical device

technical field

The invention relates to the technical field of communication, in particular to a communication device capable of shooting images.

Background technique

In recent years, with the evolution of the electronics industry and the vigorous development of industrial technology, the design and development of various electronic devices are gradually moving towards portable and easy-to-carry directions, so that users can use them in mobile commerce, entertainment or leisure anytime, anywhere. use. For example, various image acquisition devices are widely used in various fields, such as electronic devices such as smart phones, wearable electronic devices, and aerial photography devices. Take it out at any time when you need it, acquire and store the image, or upload it to the Internet through the mobile network, which not only has important commercial value, but also adds color to the daily life of the general public.

With the improvement of the quality of life, and with the improvement of the quality of life, people have more demands for images, and therefore the image acquisition device provides more and more functions. For example, most of the existing smartphones are equipped with a front camera and a rear camera. Generally speaking, the front camera can be used to take selfies. Compared with the front camera, the rear camera usually has higher specifications, so Can be used to shoot images of various scenes. Users can also hold the smartphone and rotate it in the horizontal direction to make the rear camera shoot continuously and obtain multiple partial-angle images, and then use the image processing program installed in the mobile phone to perform calculations on the partial-angle images to combine them. Produces 360-degree panoramic images. However, it is difficult for the users to rotate the smartphone in the horizontal direction at the same speed, so the obtained 360-degree panoramic image may have different partial widths.

For another example, people hope that the image quality captured by the image acquisition device of a smartphone is as similar as possible to that captured by a single-eye camera. Therefore, mobile phone manufacturers continue to improve the specifications of the rear lens, For example, increasing the aperture value of the rear lens makes the captured image sharper at the focus point but blurry outside the focus point. Of course, the increase in the specifications of the rear camera will also increase the overall manufacturing cost of the smartphone, which in turn brings troubles to smartphone consumers.

According to the above description, the existing communication device with the image capture device has room for improvement.
