Provided is a machine tool spindle balancer that stably pulls and biases the spindle unit upward and thus reduces the load of the lift means for moving the spindle unit vertically, is easily applicable to existing machine tools, highly durable, downsizable, and has a simple structure advantageous in production cost.A spindle balancer 30 comprises a gas spring 31 having a cylinder body 32, a rod 33, and a compressed gas. The gas spring 31 is provided above the spindle unit 10. The bottom end of the rod 33 is coupled to the spindle unit 10 so that the spindle unit is pulled and biased upward by the biasing force of the gas spring 31 that is applied on the rod 33, whereby the biasing force of the gas spring 31 serves to reduce the load of the lift mechanism 20.
摘要:
In an image encoder, a first quantization section which is selected when normal image quality is required performs quantization by dividing a wavelet transformation coefficient by a quantization step size and by thereafter rounding down a fraction thereof. On the other side, a second quantization section which is selected when high image quality is required performs quantization by dividing a wavelet transformation coefficient by a quantization step size, by adding 0.5 to the addition result, and by thereafter rounding down a fraction thereof. Therefore, the width of a dead zone where coefficients are quantized to a value of 0 is narrower than that in the first quantization section, and higher image quality is obtained accordingly.

摘要:
In an image synthesizer (1), code stream analyzers (10, 11), code block extraction units (12, 13) and EBCOT decoders (14, 15) work together to decode encoded code streams (D10, D11) encoded according to the MPEG-2000 Standard and generate quantization coefficients (D16, D17) for each code block. In a cross-fading unit (16), multipliers (17, 18) multiply the quantization coefficients (D16, D17) by coefficients (α(t), (1−α(t))) and an adder (19) adds together the results of multiplication to provide a cross-fading quantization coefficient (D20). An EBCOT encoder (20), rate controller (21) and code stream generator (22) work together to encode the cross-fading quantization coefficient (D20) to provide a final encoded code stream (D23). Therefore, the image synthesizer (1) can combine two encoded code streams easily and effectively with a reduced use of a memory capacity.

A color ID card for color matching that includes: a matching card; and a to-be-matched card for color matching with the matching card. Wherein, the matching card and the to-be-matched card are both printed with a color ID pattern that is a combination of colors corresponding to, on a digit basis, an identification number of identifying a matching object.
摘要:
In wavelet transform encoding, high-quality encoding is to be realized by enabling picture quality control from one fractional area to another. An input picture 100 is read out in an amount corresponding to a number of lines required for wavelet transform and buffered in a memory unit 6. The input picture then is wavelet transformed in a wavelet transform unit 2 and quantized in a coefficient quantizing unit 3. In quantizing wavelet transform coefficients, the wavelet transform coefficients are multiplied by weighting coefficients from one sub-band to another. The weighting coefficients are determined using the analysis information of a specified block area in a picture, such as motion information and texture fineness information. This enables fine quantization control in terms of a picture block as a unit.
摘要:
A predetermined area of input image data (100) is read and stored into a memory section (1). As soon as data is stored in the data read memory section (1), wavelet conversion filtering is performed on the image area, in the horizontal or vertical direction, by a wavelet conversion section (5). The wavelet conversion section (5) comprises a fixed-point type wavelet conversion section (3) and an integer type wavelet conversion section (4). Data from the data read memory section (1) is switched and controlled by a switching section (2), and supplied to either the fixed-point wavelet conversion section (3) or the integer type wavelet conversion section (4).
