  • Publication number: 20080112636
    Abstract: The invention provides an adjusting apparatus and a method thereof for adjusting a 3D image constituted by a plurality of interlaced first-eye-viewed image lines and second-eye-viewed image lines to be outputted to a display panel. However, in practice, there is a leakage problem in a pair of glasses for viewing the 3D image. Therefore, the invention solves the leakage problem by matching a plurality of pre-stored leakage values and then generating a proper output with a corrective calculation.

  • Publication number: 20070253634
    Abstract: The invention discloses an image processing apparatus for improving the definition of an input image. The input image consists of a plurality of pixels, and the pixels are divided into an edge portion and a background portion. The image processing apparatus includes a compound operating unit, a sharpness processing unit, and an edge detecting unit. The compound operating unit is used for generating a noise-eliminated image by subjecting the input image to an open-close process and a close-open process. The sharpness processing unit is used for generating an enhanced image by subjecting the input image to a sharpness process. The edge detecting unit is used for receiving the noise-eliminated image and the enhanced image and determining whether each pixel of the input image belongs to the edge portion or the background portion, so as to selectively output the gray level of each pixel of the enhanced or noise-eliminated image.

  • Publication number: 20070247407
    Abstract: The invention discloses a gamma adjusting apparatus for adjusting the gray level of each pixel of an image signal. The gamma adjusting apparatus includes a measuring unit, a first processing unit, a second processing unit, and a third processing unit. The measuring unit measures the lightness of N reference gray levels. The first processing unit normalizes the lightness of the N reference gray levels to generate N normalized reference values. The second processing unit compares the N normalized reference values with a standard gamma curve to generate N adjusted gray levels. According to the N reference gray levels and the N adjusted gray levels, the third processing unit sets an adjusting rule. According to the adjusting rule, the gamma adjusting apparatus is capable of adjusting the gray level of each pixel of the image signal to comply with the standard gamma curve.

  • Publication number: 20070223041
    Abstract: The invention discloses an image processing apparatus and method thereof capable of preserving a great deal of light and dark details, so as to improve the contrast of each image. Furthermore, when calculating the value of gray level, the gray levels may be divided into equal parts, each of which includes four gray levels. Accordingly, the range of gray level is changed from 0˜255 to 0˜63, such that the hardware resources can be saved.

  • Publication number: 20070216972
    Abstract: An apparatus for processing an input image including M image units is provided. Each of the M image units respectively includes N pixels. Each of the pixels respectively has an original gray scale. The apparatus includes a converting module, a gain generating module, and a contrast enhancing module. The converting module is used for generating M luminances. Based on the original gray scales of the N pixels in the ith image unit among the M image units, the converting module generates the ith luminance among the M luminances. A maximum luminance and a minimum luminance are generated based on the M luminances. The gain generating module generates a contrast gain and a minimum gray scale based on the maximum luminance and the minimum luminance. Based on the contrast gain and the minimum gray scale, the contrast enhancing module adjusts the original gray scales of the pixels in the input image.

  • Publication number: 20070216956
    Abstract: This invention relates to an apparatus for processing an input image including M input pixels. Each of the M input pixels respectively has an input gray scale. The apparatus includes a gain generating module, a contrast enhancing module, and a Gamma adjusting module. The gain generating module generates a contrast gain and a minimum input gray scale in accordance with the input gray scales of the M input pixels. The contrast enhancing module adjusts the input gray scales in accordance with the contrast gain and the minimum input gray scale, to generate an intermediate image. The intermediate image includes M intermediate pixels, and each of the M intermediate pixels respectively has an intermediate gray scale. The Gamma adjusting module adjusts the intermediate gray scales lower than a first threshold in accordance with the contrast gain and outputs the adjusted intermediate image as an output image.
