- Fig. 6 is a schematic diagram of information processing of the image correction system and method thereof of the present invention.
- Fig. 12 is a schematic diagram of the aspect ratio correction of the circumscribed new coordinate axes of the image correction system and method thereof of the present invention.
- An aspect correction element 4213 connected to the tilt correction element 4212, can obtain a second total number of pixels in the horizontal direction (w") and a second vertical direction according to the original image equal aspect ratio (h/w) The total number of pixels (h"), and output a second pixel level based on the second total number of pixels in the horizontal direction (w"), the total number of pixels in the first horizontal direction (w') and the first pixel horizontal coordinate (x') coordinate (x"), and output a second pixel vertical coordinate (y') according to the first pixel vertical coordinate (y'), which is used to correct the image output to the display screen 43 to be consistent with the original
- a control switch element 4214 which is connected with the length-width correction element 4213, is used to control the image displayed on the display screen 43 to be a corrected original shot image or an uncorrected original shot image, and the The length and width correction element 4213 can use the total number of pixels in the original horizontal direction (w), the total number of pixels in the original vertical direction (h), the horizontal coordinate (x) of any original pixel, the vertical coordinate (y) of any original pixel, the second The total number of pixels in the horizontal direction (w"), the total number of pixels in the second vertical direction (h"), the horizontal coordinates of any second pixel (x"), and the vertical coordinates of any second pixel (y") are sent to the control switch Element 4214, as shown in Figure 6, if the control switch element 4214 is turned off, the total number of pixels in the original horizontal direction (w), the total number of pixels in the original vertical direction (h), the horizontal coordinates of any original pixel (x), any The original pixel vertical coordinates (y) output the uncorrected original shooting image
- the image information file can include the original shooting image and tilt angle information, and the source of the image information file is:
- the analysis device itself has a photographic lens and a gravity angle sensor
- the original photographed image can be produced by photographing the photographic lens, and the tilt angle information can be detected by the gravity angle sensor;
- the aforementioned surrounding frame in this case is a circular frame, that is, the center of the original image is the center of the circle, the four vertices of the image are circumscribed in a circle (the center rotates the image), and the four vertices of the image boundary of the original shot image are in contact with the circular frame, so that Figure 9 further illustrates that when the center of the original image is taken as the center, the four vertices of the image circumscribe a circle (center rotated image), taking Figure 9 as an example, if the width of the original image is still w pixels, and the height is still h pixels, then the circle is circumscribed by the four vertices of the image
- the circle’s horizontal upper-right tangent and vertical downward-left tangent are the new coordinate axes.
- the projection from the mobile phone to the mobile phone or the TV from the mobile phone can be automatically extended to the maximum displayable state of the monitor. Therefore, in this case, the original image is used to correct the aspect ratio (h/w) , so the aspect ratio correction in this case does not need to care about any display screen specifications (for example: the number of pixels in length and width).
- the image regression application unit outputs a first total number of horizontal pixels (w') and a first vertical The total number of direction pixels (h') and generate a surrounding frame, which is in contact with the four vertices of the image boundary of the original captured image 1602;
- the image regression application unit obtains a second total number of pixels in the horizontal direction (w'') and a second total number of pixels in the vertical direction (h'') according to an aspect ratio (h/w) of the original image used to output the image , and output a second pixel horizontal coordinate (x") according to the second total number of pixels in the horizontal direction (w"), the first total number of pixels in the horizontal direction (w') and the first pixel horizontal coordinate (x') , and then output a second pixel vertical coordinate (y'') according to the first pixel vertical coordinate (y'), which is used to correct the image output to the display screen and the image length and width of the original captured image
- the ratio is consistent with 1604.
- the present invention can continuously correct and return to the horizontal image in the form of software, so there is no need to use a three-axis stabilizer. In addition to saving costs, it is also possible to carry a heavy three-axis stabilizer with many components and unchanged use when shooting. shaft stabilizer.
