Embodiment
Below, in conjunction with the accompanying drawings one embodiment of the present of invention are elaborated.
Fig. 2 is the horizontal angle repair apparatus structured flowchart according to the built-in camera communication terminal of the embodiment of the invention.As shown in the figure, it comprises: wireless communication part 21, carry out radio frequency communications with the base station, and establish communication channel, and, provide the information exchange channel that needs for communication service by the communication channel transceive data.In the filming image pattern, to the terminal control part 22 of the camera control part 25 indication remedial water straight angles; Reply horizontal angle and repair order,, repaired the camera control part 25 of image data to display part 29 outputs by image rotating part 26 image rotating data; Image data is rotated to corresponding to the angle by horizontal angle accounting portion 27 horizontal angles of adjusting, and get rid of the redundance of image data according to definition, to 25 transmission of camera control part corresponding to definition laterally and the image rotating part 26 of the image data of vertical ratio; Adjust by the gravity direction of gravity sensing 28 detections and the trunnion axis between the terminal camera central shaft, to the horizontal angle accounting portion 27 of image rotating part 26 transmission.
Terminal control part 22 is data transmit-receive actions of control wireless communication part 21, and communication service is provided, and in internal memory 23 composing document systems, thereby stores the image that is taken.
Terminal control part 22 is at the image photograph mode, and to the camera control part 25 indication remedial water straight angles, the horizontal angle by camera control part 25 is repaired by image sensor 24 captured images outputs to display part 29.Terminal control part 22 is to provide horizontal angle to repair menu at the image photograph mode by choice menus, thereby when selecting horizontal angle to repair menu, to the camera control part 25 indication remedial water straight angles.
Camera control part 25 is to drive image sensor 24, reads image data, replys horizontal angle and repairs indication, thereby pass through image rotating part 26 image rotating data, and export the image data of the remedial water straight angle to display part 29.
Image rotating part 26 is that image data is rotated to angle corresponding to the horizontal angle of adjusting by horizontal angle accounting portion 27, and get rid of the redundance of image data according to definition, to 25 transmission of camera control part corresponding to definition laterally and the image data of vertical ratio.
Horizontal angle accounting portion 27 is horizontal angles of adjusting between the central shaft of the gravity direction that detects by gravity sensor 28 and terminal camera, is transferred to image rotating part 26.In addition, horizontal angle accounting portion 27 is horizontal angle requirements of in-call image rotating part 26, drive gravity sensor 28, the perception gravity direction, and reception is for the rake ratio dependency number code data of the terminal camera central shaft of gravity direction, accounting is transferred to image rotating part 26 corresponding to the horizontal angle of digital data.Fig. 3 is the operational flow diagram according to the image horizontal angle method for repairing and mending of the built-in camera communication terminal of the embodiment of the invention.As shown in the figure, in the image photograph mode, the horizontal angle of judging the user is repaired menu and is selected, and replys when selecting horizontal angle to repair menu, drives gravity sensor, detects gravity reversal's stage; Receive inclined for the terminal camera of gravity direction than dependency number code data from gravity sensor, adjust stage corresponding to the horizontal angle of digital data; To rotate to by the image data that image sensor is taken corresponding to the angle of adjusting horizontal angle, get rid of redundance in the image data, to the picture output stage that laterally reach the image data of vertical ratio of display part transmission corresponding to definition according to definition.
Suppose that the user selects horizontal angle to repair menu at the image photograph mode, when built-in camera communication terminal (following abbreviation camera terminal) the indication remedial water straight angle, the camera terminal is replied the input of Menu key at the image photograph mode, the output horizontal angle is repaired menu, judge user's horizontal angle repairing menu selection, and repair in horizontal angle and to reply when menu is selected, drive gravity sensor and detect gravity direction.
The camera terminal is from the rake ratio dependency number code data of gravity sensor reception for the terminal camera central shaft of gravity direction, adjusts the horizontal angle corresponding to digital data.
Fig. 4 a, Fig. 4 b are in the image horizontal angle method for repairing and mending of Fig. 3, the schematic diagram of gravity direction and image horizontal angle.Fig. 4 a is a gravity direction and camera central shaft schematic diagram when being acute angle, and Fig. 4 b is a gravity direction and camera central shaft schematic diagram in obtuse angle the time.
Image 41 is with the ground surface fixing state that is as the criterion.Camera terminal explanation is for the horizontal direction H of image 41, under the state that tilts, aims at focus and takes to image.The image that the image sensor 43 of camera terminal receives is the angle that is inclined to corresponding to horizontal angle (θ), and the camera terminal is that image data is rotated into angle corresponding to horizontal angle (θ), thereby during image output 44, has got rid of the inclination of image.
The camera terminal is that gravity direction (G) and camera central shaft (C) are when being acute angle, the acute angle of adjusting used be horizontal angle, and gravity direction (G) and camera central shaft (C) be in obtuse angle the time, will deduct 90 degree from the obtuse angle of adjusting and the end value obtained is used and is horizontal angle.
The camera terminal is that the image data that will take by transducer rotates to corresponding to the angle of adjusting horizontal angle, and, outputing to picture corresponding to laterally the reaching the image data of vertical ratio of definition to the display part transmission according to redundance in the definition eliminating image data.
When the user confirms to output to the image of display window, can confirm the image that can not cause that image tilts owing to the inclination of terminal camera.
If the user confirms the photo photography, the camera terminal just can be stored into internal memory with the image that outputs to current display window.
In sum, according to the present invention, can repair the image that the inclination owing to terminal camera takes place distorts, shooting meets the image of level, and need not user's concrete manual operation, also terminal positioning can be taken in the position of approaching level, thereby, also can obtain the image that auto-mending tilts even occur rocking or tilting.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
