Abstract: A size positioning device applied to a window covering cutting apparatus includes a manual operating member, a limit assembly and a position detecting device. The limit assembly can be driven by the manual operating member to move. The position detecting device can detect a position of the limit assembly and generate a position detecting value. According to the position detecting value, a signal processing circuit of the window covering cutting apparatus generates adjusted position information and target position information, and displays the adjusted position information on an output device. The manual operating member is adjusted according to the adjusted position information to move the limit assembly until the adjusted position information equals to the target position information, after which a cutting device cuts a first end of the window covering. Thereby, a risk of cutting the window covering to a wrong size due to miscalculation by users is reduced.

Abstract: A window covering cutting apparatus includes a supporting base, a mounting base, a cutting device, a size positioning device, an input device, an output device, a storage device and a signal processing circuit. The signal processing circuit calculates acquired information including product information, a mounting mode, cutting size information and a position detecting value to generate adjusted position information and target position information, and displays them on the output device. The size positioning device is adjusted until the adjusted position information equals to the target position information, after which the signal processing circuit sets the cutting device to cut the window covering to the required size. Since a correct cutting position of the window covering is obtained by the calculation of the signal processing circuit, a risk of cutting the window covering to a wrong size due to miscalculation by users is reduced.

A central device (115) may be configured with one or more device identifiers of one or more devices that are designated as control devices.

Abstract: A method for image compression and a circuit system thereof are provided. In the method, pixel values of an image are obtained. A compression scenario is decided, for example, a uniform-quantization manner or a non-uniform-quantization manner is used for an M-bit image being compressed to an N-bit image so as to decide codeword sections for the image.

Afterwards, a random number is generated for deciding codeword and index for original value of each of the pixels. An index table is accordingly formed. The index table is provided for obtaining the codeword in a decoding process by querying a codebook with the index.

The system includes an image acquisition circuit having a lens, a color filter and an image sensor and a processing circuit. In the method performed by the processing circuit, a second frame image is retrieved from a motion image, and a first frame image that has undergone noise reduction can be retrieved from a memory.

The motion detection is referred to as a reference for determining how to perform 3D noise reduction. A compensation value for channel imbalance between the adjacent channels can be estimated based on the image under noise reduction in a same buffer. While the pixel channel imbalance is compensated, the image is then restored by an interpolation method.
