  • Patent number: 8629901
    Abstract: A method of revising depth of a three-dimensional (3D) image is disclosed. The method comprises the following steps: firstly, at least one initial depth map associated with one image of the 3D image pair based on stereo matching technique is received, wherein the one image comprises a plurality of pixels, and the initial depth map carries an initial depth value of each pixel. Then, the inconsistence among the pixels of the one image of the 3D image pair is detected to estimate a reliable map. Finally, the initial depth value is interpolated according to the reliable map and the proximate pixels, so as to generate a revised depth map by revising the initial depth value.

  • Patent number: 8483516
    Abstract: A super resolution (SR) method or system with database-free texture synthesis is disclosed. An input image is up-sampled to result in an up-sampled image. It is determined whether the input image possesses a smooth region. Edges of the up-sampled image are enhanced, and the enhancing edges step is bypassed if the smooth region has been detected. The enhanced or unenhanced up-sampled image is texture synthesized by taking the input image as texture example, thereby resulting in a synthesized image.

  • Patent number: 8432491
    Abstract: An object-based system and method of directing visual attention by a subliminal cue is disclosed. An object detector detects an object in an input image, thereby resulting in a cued object served as an object-based subliminal cue. An enhancement unit enhances saliency of the cued object in the input image by respectively and differently adjusting image characteristic of the cued object and an area other than the cued object, thereby generating a cue image. A mixer selects between the cue image and the input image, thereby resulting in a sequence of output images composed of the input images and the cue images, each of which is interposed between the adjacent input images.

  • Patent number: 8400393
    Abstract: A method of controlling backlight module, a backlight controller and a display device using the same are provided herein. First, an image having a plurality of regions is received, wherein the image is displayed by a plurality of color backlights which are provided from the backlight module. Next, a first average of a characteristic in a specific region of the image is calculated, wherein the specific region is one of the regions. According to the first average of the characteristic and a weight function, a characteristic weight is calculated. Next, one of the color backlights provided to the specific region is adjusted according to the characteristic weight. Therefore, adjusting the color backlights according to the image content can enhance the displaying quality of the image and adaptively reduce the artifacts perceived by human eyes in different images.
