A content-adaptive overdrive system and method, for a display panel, include a frame difference device and an overdrive device. The frame difference device generates a frame difference map according to a current frame and a previous frame. The frame difference map includes a number of flags respectively indicating similarity between corresponding pixels or blocks of the current frame and the previous frame. The overdrive device adaptively performs an overdrive function based on the frame difference map, the current frame, the previous frame and an overdrive lookup table, hence resulting in an overdrived frame.

A method of motion detection using motion information of neighboring pixels, adaptive for determining whether a plurality of target pixels in a current field are moving pixels, is provided. First, it is determined whether a neighboring pixel in a previous field corresponding to the target pixel in the current field is the moving pixel. If the neighboring pixel in the previous field is the moving pixel, the target pixel is determined as the moving pixel and otherwise it is further determined whether the neighboring pixels around the target pixel in the current field are the moving pixels. If the neighboring pixels in the current field are the moving pixels, then the target pixel is determined as the moving pixel. Accordingly, the mistakenly judged static pixels can be found and modified to moving pixels, such that the accuracy of motion detection can be increased.

One embodiment of the present invention sets forth a method for detecting a bad edit. The method includes receiving a 3:2 film-mode video signal comprising a sequence of video fields, for each of the sequence of video fields, determining a state for the each video field based on a first moving-pixel count for the each video field with respect to a previous same-parity video field for the each video field and a second moving-pixel count for a first immediately preceding field for the each video field with respect to a second previous same-parity field for the first immediately preceding field, and identifying the 3:2 film-mode video signal as a bad edit if a predetermined state transition has been detected in the sequence of video fields.

A frame structure of a concentrator type solar cell module, with its carrier portion and connection and fixing portion of a frame edge designed into a vertical and stack-up arrangement, thus reducing significantly a thickness of the frame edge, such that upon carrying a concentrator lens array, the proportion of light receiving area is increased, hereby raising the photo-electrical conversion efficiency of the concentrator type solar cell module. Therefore, in this way, in a condition of maintaining a same load mechanical strength, the ineffective light receiving area can be reduced significantly, while raising the photo-electrical conversion efficiency of the solar cell module.

A method of motion detection using an adaptive threshold, adaptive for determining whether a plurality of target pixels in a current scan line are moving pixels or not, is provided. First, a first threshold is given for determining whether the target pixels in the current scan line are moving pixels. Then, a number of moving pixels in a previous scan line of the current scan line is calculated and determined whether larger than a second threshold. If the number of moving pixels is larger than the second threshold, the first threshold is adjusted by a decrement, and then whether the target pixels in the current scan line are moving pixels is determined by using the adjusted first threshold.
