摘要： A method and system for correcting defective pixels of a color image, which first performs an interpolation on a Bayer image captured by an image sensor to thus reconstruct red, green and blue (RGB) colors corresponding to each pixel and obtain an RGB image, then converts the RGB image from the RGB domain to a chroma domain, and finally uses neighboring pixel values to correct a respective defective pixel. Because a defective pixel can be distinct from the chroma domain easier than the RGB domain, it can accurately determine whether or not a pixel to be processed is defective.

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.

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.
