    摘要: A cable modem includes an amplifier, a power module, a switch circuit, a monitor signal, a duplexer and a RF matching circuit. The switch includes a PMOS transistor and a first electronic switch. The RF matching circuit included a second electronic switch and an electronic matching device. The monitoring signal source is configured for outputting a control signal. When the monitoring signal source stops outputting the control signal, both the first electronic switch and the PMOS transistor are turned off to cut off the power to the amplifier, the second electronic switch is turned on, and conducts the RF signal received by the signal receiving/transmitting circuit to the duplexer which further conducts the RF signal to the radio frequency matching circuit.

    摘要: An edge enhancement method and apparatus for Bayer images are provided. The apparatus stores the raw Bayer image data into a line buffer. After having directly read the raw Bayer image data from the buffer, the apparatus computes luminance characteristic values, analyzes the edge characteristic and then outputs the edge characteristic values. According to the edge characteristic values, the edges in the raw Bayer image data are enhanced. The apparatus simplifies the processing complexity of the rear-stage circuit by directly enhancing the edges in the Bayer image, and is easily combined with the post image processing mechanism. Conventionally, the raw Bayer image is converted to the RGB image or the YUV image and then the edge enhancement operation is performed. The invention reduces the computing volume and memory size. Also, performing the edge enhancement operation in advance helps to identify the interpolation direction and ease the annoying noise.

At first, a first primary index and a first sub-index are obtained by performing an index mapping on a value of the video signal. Next, a first gamma value is obtained by performing a table lookup on the first primary index and the first sub-index. Next, a second primary index and a second sub-index are obtained by performing the index mapping on the first gamma value. Next, multiple thresholds are obtained by performing the table lookup on the second primary index and the second sub-index. Finally, the value of the video signal and the multiple thresholds are compared to accordingly correct the first gamma value and generate the gamma correction value.

    摘要: A magnetic latch assembly includes a first body, a second body, and a magnetic block and a magnetic latch. The magnetic block is movably disposed on the first body; therefore, it can be selectively moved close to or far away a first opening of the first body. The magnetic latch is disposed on the second body corresponding to a second opening of the second body. In addition, two ends of the magnetic latch form a hook portion and a tip portion, respectively. When the first body is close up against the second body and the magnetic block is moved close to the first opening, the magnetic block and the tip portion repel each other due to magnetic force so as to drive the magnetic latch rotating, so that the hook portion is moved and passing through the second opening and the first opening and hooked against the first body.

    摘要: A method and system of eliminating color noises caused by an interpolation, which performs an interpolation on a Bayer image obtained by an image sensor to restore red, green and blue colors of each pixel. Interpolated image is converted into a chromatic domain in order to rapidly use chroma pixel values of a pixel previously processed to eliminate color noises to update the original chroma pixel values in a median filter with 3×3 area of 2D, thereby increasing the color noise filtering capability of the median filter, and a low-pass filter is used to further eliminate the uneven effect of clustered color noises filtered out by the median filter.

    摘要: An automatic exposure control method and compensation apparatus are disclosed. It includes a coordinate system having sub-ranges with different corresponding exposure compensation values. It includes the setting of bright and dark regions threshold values and the calculation of the ratios of the pixel count in an image where the luminance of each pixel is higher than the bright area threshold value for obtaining a bright area ratio, and also includes the calculation of the ratio of the pixel count in an image where the luminance of each pixel is lower than the dark area threshold value for obtaining a dark area ratio. Afterwards, the image position in the coordinate system is determined. When the image position in the coordinate system is fallen inside one of the sub-ranges, the corresponding exposure compensation value of the sub-range where the image is located is given to compensate the exposure value of the image.
