Description

Photo automatic rotating device, system and storage device

The present invention relates to a device capable of automatically rotating a photo image, which can be directly judged by the device to directly or laterally photograph the camera without manual operation, and the device uses the image processing method to determine the photo content. Direction, and automatically rotate the photo from the horizontal display to the straight display or from the straight display to the horizontal display for easy viewing of the photo.

In recent years, the computer industry has developed rapidly. Many cameras or cameras are digital, and a large number of electronic products have camera and photography functions, so the chances of viewing digital photos or multimedia images become very frequent.

As shown in FIG. 1 , it is a series of images or photo files taken by a conventional digital image capturing device. Because of the framing relationship when taking a photo, the direction of the handheld camera or the camera may be horizontal or straight, resulting in shooting. The images will be in a variety of directions. The viewer will see a series of photographs taken under normal conditions. The photo 22 is oriented to the right, the 23 is upright, and the 24 is oriented to the left.

Due to the advancement of digital technology, a large number of photos are often stored in auxiliary memory such as a flash drive or a CD, or uploaded to a network storage server, a network hard disk, or a cloud memory. And other storage devices.

The photo viewer can output to an output device such as a liquid crystal display (LCD) or a projector, because some photos are straight when shooting, and some photos are horizontal, so when viewing a series of photos, in order to view the scene in the photo See clearly, it is often necessary to tilt the head 90 degrees to the right or 90 degrees to the left.

If you look at the head to the right or to the left, you will feel uncomfortable. Some users will need to use the image processing software to adjust all the photos to the adult direction, as shown in Figure 2. Easy to watch.

It is not only inconvenient and time-consuming to rotate the photo 90 degrees clockwise or 90 degrees counterclockwise through the image processing software. In particular, the capacity of the digital photo memory card is increasing, sometimes after storing thousands of tens of thousands of photos. If you want to take it out and upload it to a social networking site such as Facebook, it is not convenient to rotate a very large number of photos or video images.

Referring to FIG. 3, the authoring apparatus provides a device for automatically rotating a photo or multimedia movie. The device 14 includes a processor 10 and a memory unit 11 electrically coupled to the input unit 12 and the output unit 13.

The input unit 12 can be a digital camera or an image capturing device, which can capture an image of an object to be captured and input it to the device; the device can also be included in the image capturing device or the image capturing device can be transmitted through the image capturing device. The image is transmitted to the memory unit 11 of the device by wired transmission or wireless transmission.

After the device turns the direction of the multimedia photo or video, it can also transmit the image to the remote server through wired transmission or wireless transmission, for example, transferring the processed photo or video image to the Facebook storage. In the unit, to facilitate viewers to view photo photos or video files.

The first embodiment of the device is a digital system or device, and the digital system can be a digital camera or a digital video recorder, a driving recorder, a smart phone, etc., which has the function of photography or photography, and the device can be taken after photography or photography. The image is directly rotated directly by the photo or video image and stored in the memory unit in the device.

The second embodiment of the device may be a digital system or device in the digital system A social networking website (for example, Facebook, etc.) can be installed. After the user uploads the photographed or photographed image to the website space of the embodiment, the image can be automatically rotated and then stored through the system or device. As shown in Fig. 1, the plurality of non-positive direction photographs 22 and 24 are automatically converted into the photographs 32, 23, and 34 in the second figure, all of which are in the upright direction, so that the viewer can easily browse.
