20090316019 | TONE ADJUSTMENT METHOD FOR DIGITAL IMAGE AND ELECTRONIC APPARATUS USING THE SAME - A tone adjustment method for a digital image and an electronic apparatus using the same are presented. The method includes steps. A digital image is loaded. A detail image layer and a primary image layer are generated according to the digital image. A tone mapping procedure is performed on the primary image layer, for generate a tone mapping layer. A detail gain lookup table is loaded and then a corresponding gain is looked up according to each pixel value in the primary image layer, for generate a detail gain adjustment layer. A detail gain control procedure is performed and then a detail gain adjustment is performed on the detail gain adjustment layer and the detail image layer, for generate a gain correction layer. The gain correction layer and the tone mapping layer are combined, and then a combined layer is output, thereby completing the tone adjustment for the digital image. | 12-24-2009 |

20140029929 | AUTO-FOCUS METHOD - An auto-focus (AF) method adapted for an image capturing device includes following steps. When a first press signal generated by a user pressing a button of the image capturing device is detected, a local peak searching method is applied to perform an AF procedure. It is determined whether a second press signal generated by the user pressing the button is detected. If not, it is determined whether a first released signal generated by the user releasing the button is detected. The continuous pressing count is calculated according to the first released signal and the first press signal that are continuously generated. Whether the continuous pressing count is greater than a first threshold is determined. If yes, a global peak searching method is applied to perform the AF procedure. If not, the local peak searching method is still applied to perform the AF procedure. | 01-30-2014 |
20150213589 | IMAGE CAPTURING DEVICE AND METHOD FOR CALIBRATING IMAGE DEFORMATION THEREOF - An image capturing device and a method for calibrating image deformation thereof are provided. The image capturing device has a first image sensor and a second image sensor and the method includes following steps. A plurality of image groups are captured through the first image sensor and the second image sensor. Each of the image groups includes a first image and a second image, and the image groups include a reference image group. Whether an image deformation occurs on a first reference image and a second reference image in the reference image group is detected.
