| 20090087173 | Image capturing apparatus with movement compensation function and method for movement compensation thereof - A method for compensating movement of an image capturing apparatus is applied in a photographing mode whose exposure time is greater than the safe shutter time. The method includes the steps of: capturing a long exposure image under the desired exposure time and a short exposure image with an exposure time smaller than or equal to the safe shutter time, and recording a camera motion signal in the exposure time of the long exposure image. The image-shift signal is used to reconstruct the short exposure image and form a reconstructed image, and an image analyzing algorithm is utilized to extract the reconstructed image and the short exposure image of a different frequency component. Finally, different frequency components of the image are fused according to the specific ratios to produce a clear output image. | 04-02-2009 |
| 20090103910 | System for compensating camera movement and a calibration method thereof - A method for compensating camera movement solves the problem of the captured image becoming blurred due to involuntary camera movement in the following way. Firstly, a camera with a look-up table is provided. Next, after a trigger signal is received, the camera movement and the environmental brightness are detected to generate a movement value and a brightness index. A compensation mode and a set of parameters that correspond to the movement value and the brightness index are selected from the look-up table. Finally, when an image-capturing signal is received, the movement compensation modules of the camera are driven by referring to the compensation mode and the parameters to capture a sharp image in a best mode. | 04-23-2009 |
| 20090123141 | Image capturing apparatus with suppression of image blur and method thereof for suppressing image blur - A method for suppression of image blur is applied to an image capturing apparatus in a photography mode whose exposure time is set to be greater than a safe exposure time. The method comprising the following steps: capturing a long exposure image with the present exposure time, and a short exposure image with an exposure time smaller than or equal to the safe exposure time in the same landscape. Besides, obtain a locus signal in the process of long exposure image capture. Afterwards, execute an arithmetic procedure to smooth the short exposure image, and then produce a point scale image using the auxiliary arithmetic of locus signal. Finally, process the long exposure image and the point scale image with multiplication arithmetic to restore the long exposure image, thus forming an output image. | 05-14-2009 |
| 20090153690 | Method for determining imaging quality of a camera via a motion sensor and ISO settings - A method for determining imaging quality of a camera via a motion sensor and ISO settings uses a CCD sensor module, an ISO setting module, a shutter module, a zoom module and a color temperature module to provide all kinds of information of an object image and transmit the information to an image processing unit to be processed, uses a motion sensor module to provide camera motion information, and then uses the image processing unit to estimate the level of motion of the camera and adjust and correct the information provided by the modules according to the camera motion information provided by the motion sensor module to select optimum settings and compression quality. | 06-18-2009 |
| 20090169129 | Method for automatically transforming color space and prospect of an imaging device - A method for automatically transforming color space and prospects of an imaging device is disclosed. The method at least includes: selecting a source image and a target image; transforming color space automatically wherein the color spaces of the two images are respectively transformed into another color space; matching levels, wherein features are grouped and the most similar adjacent field is searched; and copying the chrominance values—distributing the best matched brightness level distributions of said another color space of the source image and the target image, finding the pixels corresponding to the target image, and then copying the chrominance values to the source image to transform prospects. | 07-02-2009 |
| 20100123806 | IMAGE COMPENSATION METHOD AND IMAGE ACQUISITION DEVICE USING THE SAME - An image compensation method adapted to reduce noise of a first image captured by an image acquisition device at a high ISO mode. The image compensation method includes the following steps. A Bayer pattern is obtained from the first image. A green pixel signal, a low-resolution binned original luminance signal, and an original chrominance signal are respectively generated according to the Bayer pattern. A high-resolution analog luminance signal is generated by using the green pixel signal. The high-resolution analog luminance signal and the low-resolution binned original luminance signal are combined, and a compensated high-resolution luminance signal is output. A second image is generated by combining the compensated high-resolution luminance signal and the original low-noise chrominance signal. | 05-20-2010 |
| 20100141737 | METHOD FOR REAL-TIME PROMPTING STITCHING DEGREE OF PANORAMIC IMAGE - A method for real-time prompting a stitching degree of a panoramic image applied to a digital image pickup device. At first, a boundary band of a first image is captured to obtain an boundary image, and a second image is detected. Next, the boundary image and a local image of the second image are merged, and an association value of the boundary image and the local image of the second image is calculated. Then, the second image after being merged with the boundary image and a prompt signal corresponding to the association value are displayed on a screen. | 06-10-2010 |
