Handheld electronic device capable of combining image and method thereof

The present invention relates to a dual-lens handheld electronic device, and more particularly to a handheld electronic device and method thereof that can simultaneously capture and interchange scenes through dual lenses.

With the advent of the electronic age, modern society almost has a hand-held electronic device such as a mobile phone or a personal digital assistant. Whether it is communication, memo, navigation or Internet access, modern people's lives and electronic products are inseparable.

Nowadays, handheld electronic devices are becoming more and more sophisticated, small in size and versatile, especially mobile phones. Today's mobile phones can not only communicate, but also the above network, and even take pictures. Because mobile phones are small and easy to carry around, more and more people use mobile phones instead of cameras. Taking photos by mobile phone, most of them use the self-timer method. You can record your life at any time without having to help others, and make full use of the convenience that mobile phones can carry with you.

As video communication technologies mature, more and more mobile phones are equipped with two sets of camera devices, one for taking pictures and the other for video. The lens used for video is usually located on the same side of the screen, allowing you to communicate with others while seeing each other's images, making people closer to each other. Recently, more mobile phones can use video. The lens or camera lens is used as a camera lens for taking pictures. By taking a self-portrait of the video camera, you can determine your position on the screen and capture the lens you want to capture more accurately.

However, it is convenient to use a mobile phone self-timer, but no matter which lens is used for taking pictures, there are still defects. For example, when the self-timer wants to capture both his own images and the scenery he is in, or take pictures in places that are not easy to view (such as exhibitions or signings, etc.), you have to take pictures of them. It is difficult for the environment or personnel to choose a satisfactory background (such as a specific exhibit or star).

Therefore, how to maintain the convenience of portable electronic devices that can be carried around, and to meet the various needs of users in taking pictures, the inventor has proposed a combination of dual-photographing scenes based on years of research and development and many practical experiences. The dual lens handheld electronic device and method thereof are used as an implementation and basis for improving the above disadvantages.

In view of the above-mentioned problems, an object of the present invention is to provide a handheld electronic device capable of combining images and a method thereof, so as to solve the problem that a conventional user cannot simultaneously present his own image and is satisfied when taking a self-photograph by using a handheld electronic device. Defects in the background.

According to the purpose of the present invention, a handheld electronic device capable of combining images includes a first camera module, a second camera module, a feature image processing module, a control module and a display module. The first camera module is configured to capture at least one first image. The second camera module is configured to capture a second image. The feature image processing module is electrically connected to the second camera module for capturing a portion of the second image to form a feature image. Control module and first camera module, second camera module and feature image The processing module is electrically connected, and the control module drives the first camera module and the second camera module to simultaneously capture according to the command, and the control module receives the first image and the feature image, and combines the first image and the feature image, and A third image is formed on the display module.

The feature image processing module identifies the second image as at least one feature and a background, and removes the background to form a feature image. The feature image processing module is characterized in that the feature background and the background are different in focus, so that the background of the feature is more blurred than the feature, so that the blurred portion in the second image is recognized and removed to form a feature image.

The handheld electronic device that can be combined with the image further includes an input unit electrical connection control module, wherein the input unit is configured to generate a command, and the control module drives the first camera module and the second camera module to simultaneously capture.

In addition, the present invention further provides a method for combining images, which is applicable to a handheld electronic device. The handheld electronic device includes a control module, a display module, a first camera module, and a second camera module. A feature image processing module, the step of combining the images includes: driving the first camera module to capture a first image and driving the second camera module to capture a second image; and performing feature image processing The module captures a portion of the second image to form a feature image; and the control module receives the first image and the feature image, and combines the first image and the feature image to form a third image for display in the display mode group.

The step of forming the feature image by the feature image processing module further includes: identifying the second image as at least one feature and a background, and removing the background to form the feature image. And the feature image processing module blurs the background by the feature and the background due to different focal lengths, thereby identifying and removing the blurred portion in the second image to form a feature image.

The method for combining images according to the present invention further includes: providing an input unit electrically connected to the control unit, and generating an instruction, wherein the control module simultaneously drives the first camera module to capture a first image according to the instruction; Driving the second camera module to capture a second image.

In view of the above, an image-capable handheld electronic device and method thereof according to the present invention may have one or more of the following advantages:

(1) The handheld electronic device capable of combining images and the method thereof can be matched with each other by a double lens disposed on the handheld device, so that the user can select a desired background during the self-timer and shoot the image. After that, the image or the specific image is directly combined with the favorite background, and further displayed on the display device for the user to view.

(2) With the handheld electronic device and the method thereof, which can be combined with the image, in addition to the desired background when the self-timer is selected, if the location is not easy to view, for example, a large number of exhibition venues or signing sessions, etc. , you can directly point the first camera module to the painting, exhibits or idols you want to shoot, and point the second camera module toward you at the most appropriate time (for example, the moment when the crowd spreads out). The self-timer presents the image in the background of the painting, the exhibit or the idol.
