Patent number: 8049785Abstract: An optimum image selection method for a digital photograph device selecting an optimum image by driving a vibration detection sensor mechanism is provided. In continuous photography mode, as soon as capturing an image, it detects and records the vibration amount of the image, and then compares the presently detected vibration amount with the vibration amount of the image which is stored formerly, and if the vibration amount detected presently is smaller, the image captured presently will be stored, so the clearest image will be distinguished and retained immediately by using the vibration amount.Type: GrantFiled: September 26, 2008Date of Patent: November 1, 2011Assignee: Altek CorporationInventors: Shih-Chang Han, Chin-Lung Yang, Yun-Chin Li

Patent number: 8018495Abstract: 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.Type: GrantFiled: September 26, 2008Date of Patent: September 13, 2011Assignee: Altek CorporationInventors: Yun-Chin Li, Chin-Lung Yang, Shih-Chang Han

Patent number: 7978223Abstract: 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.Type: GrantFiled: July 9, 2008Date of Patent: July 12, 2011Assignee: Altek CorporationInventors: Yun-Chin Li, Chin-Lung Yang, Shih-Chang Han

Patent number: 7856178Abstract: 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.Type: GrantFiled: September 26, 2008Date of Patent: December 21, 2010Assignee: Altek CorporationInventors: Yun-Chin Li, Chin-Lung Yang, Shih-Chang Han

Publication number: 20090169129Abstract: 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.Type: ApplicationFiled: October 15, 2008Publication date: July 2, 2009Inventors: Yun-Chin Li, Chin-Lung Yang, Shih-Chang Han
