Embodiment 1

[0032] Embodiment one: if figure 1 As shown, a zooming method of a digital photography device with a touch screen, especially a zooming method of a touch screen mobile phone with a photography function, includes: using the touch screen 101 provided by the touch screen mobile phone to input a zoom gesture, the zoom gesture is two touch points 103 and 105 in contact with the touch screen 101; the touch screen mobile phone first records the initial distance between the two touch points 103 and 105, and then records the sliding process of the two touch points 103 and 105 on the touch screen 101 in real time The current distance in the center; when the zoom gesture 102 is input to make the current distance greater than the initial distance, the touch-screen mobile phone drives the lens through the lens drive device to optically zoom to the telephoto end, and / or uses the image processing algorithm to digitally zoom the framing image Operation, the viewfinder image is the original im...

Embodiment 2

[0034] Embodiment two, such as figure 2 As shown, the difference from the zoom method in Embodiment 1 is that the zoom gesture also includes contact with the zoom slider 106 displayed on the touch screen 101, and the touch screen mobile phone moves along the linear predetermined path 107 on the touch screen 101 according to the contact. The movement performs an optical zoom operation and / or a digital zoom operation, and the predetermined path 107 may also be a curved path, a parabolic shape, or a path that rotates clockwise or counterclockwise at a certain angle.

[0035] The difference from the digital photographing device with a touch screen in Embodiment 1, especially a touch screen mobile phone with a photographic function, is that a zoom slider 106 and a linear predetermined path 107 are also displayed on the touch screen, and the zoom The gesture also includes contact with the zoom slider 106 displayed on the touch screen 101, and the processing unit 304 of the touch sc...

Embodiment 3

[0036] Embodiment three, such as image 3 As shown, the difference from the zoom method in Embodiment 1 is that the zoom gesture also includes contact with the zoom control keys 201 and 202 displayed on the touch screen 101, and the touch screen mobile phone performs an optical zoom operation and / or digital zoom according to the contact. operate.

[0037] The difference from the digital photography device with a touch screen in Embodiment 1, especially a touch-screen mobile phone with a photography function, is that zoom control keys 201 and 202 are also displayed on the touch screen 101, and the zoom gesture also includes According to the contact with the zoom control keys 201 and 202 displayed on the touch screen 101, the touch screen mobile phone performs an optical zoom operation and / or a digital zoom operation according to the contact.

Abstract

A zooming method for a digital photography device with a touch screen, characterized in that: the touch screen provided by the digital photography device is used to input a zoom gesture, and the digital photography device is controlled in real time to perform a zoom operation according to the change of the zoom gesture. The zooming method of the digital photographic device with a touch screen of the present invention can control the digital photographic device to perform the zooming operation in real time according to the change of the zooming gesture, and can check the zooming effect in real time during the process of inputting the zooming gesture, which is convenient and intuitive. In addition, the use of the touch screen to input zoom gestures eliminates the need to add physical buttons on the digital photography equipment, saving equipment space.

Description

Technical field: [0001] The invention relates to a digital photographing device with a touch screen and a zooming method thereof. Background technique: [0002] Existing digital photography equipment generally provides an optical zoom function or a digital zoom function. Optical zoom refers to changing the physical focal length of the zoom lens, thereby changing the size of the shooting angle and the magnification of the subject. Although it can capture high-quality images, the size of the optical zoom lens is generally large, so it cannot be applied to some Digital photographic equipment with limited size, such as a mobile phone equipped with a camera; and the digital zoom, which is different from the optical zoom, essentially uses a specific image processing algorithm through the central processing unit (CPU) to process the camera optics and imaging The original image generated by the sensor is cropped and then interpolated and enlarged to the resolution of the original i...
