Problems solved by technology

[0003] However, for the image frame displayed by the digital data, sometimes the brightness value of the displayed image frame will be uneven due to factors in the manufacturing process or defects in the assembly process of the internal components of the photographic device.
Especially for the uneven brightness at the edge of the image screen, the uneven brightness value will make part of the entire image screen appear darker, while other parts appear brighter, which is a serious defect from the visual point of view of the image display

Embodiment Construction

[0034] see Figure 1a , Figure 1a It is a schematic diagram of the imaging device 30 of the present invention. The present invention relates to a photographing device 30 and a compensation method used in the photographing device 30 to compensate image frames. The compensation method is a shading correction technique. Figure 1a The camera device 30 includes an image capture module 32 , a calculation module 34 , and a compensation module 36 .

[0035] The image extraction module 32 is used to first extract the first image to calculate the compensation value, and then use the compensation value to compensate the image frame of the extracted second image. Refer to Figure 1a for further reference Figure 1b , Figure 1b A schematic diagram of an image frame 40 . The image frame 40 of the first image that is extracted first includes a reference image 42 and a non-reference image 44. The reference image 42 is the oblique line area in the image frame 40, and the areas of the image...

Abstract

The invention is concerned with the photography equipment and the compensating method of the compensative image in the equipment. The equipment uses the image distilling module distill a first image and a second image by order, the first image consists of a reference image and a non-reference image. Using the computing module to compute the average value of the reference image brightness that is as a reference brightness value, the difference value between the reference brightness value of the reference image and the non-reference image brightness value is higher than a comparing value. Using the compensating module according to the compensating value that is the reciprocal of the ratio between the non-reference image brightness value and the reference brightness value, the compensating value compensate the second image.

Description

technical field [0001] The present invention relates to a photographing device, in particular to a compensation method for compensating image frames in the photographing device. Background technique [0002] Since digital cameras, digital video cameras and other photographic devices became popular, image frames generated by digital data make processing more convenient, including storage, printing, modification, etc., which enrich people's visual and spiritual life. [0003] However, in the image frame displayed by the digital data, sometimes the luminance value of the displayed image frame will be uneven due to factors in the manufacturing process or defects in the assembly process of the internal components of the photographic device. Especially for the uneven brightness at the edge of the image frame, the uneven brightness value will make part of the entire image frame appear darker and other parts appear brighter, which is a serious flaw from the visual point of view of i...
