摘要:
According to the present invention, an endoscope system having an insertion member thereof wound about a drum comprises an electronic endoscope, a drum, an angling input unit, a motor-driven angling unit, a camera control unit, a motor-driven angling control circuit unit, and a stowage case. A bending section included in an insertion member of the electronic endoscope is motor-driven to bend, and a solid-state imaging device is incorporated at the tip of the insertion member. The insertion member is wound about the periphery of the drum. The angling input unit is separated from the electronic endoscope, and used to enter a direction of bending in which a user wants to bend the bending section. The motor-driven angling unit is incorporated in the drum, and includes a driving source for driving a driving mechanism that drives the bending section. The camera control unit controls the solid-state imaging device, and includes a signal processor for processing an electric signal sent from the solid-state imaging device to generate a video signal. The motor-driven angling control circuit unit controls the movement of the bending section. The drum is rotatably stowed in the stowage case freely.

A gas spring has a cylinder body, a rod member internally slidably fitted in the cylinder body, and a gas chamber which is formed inside the cylinder body and filled with compressed gas. The seal members for sealing between the cylinder body and the rod member are disposed at both sides of the gas chamber, while ring members for partitioning the gas chamber are disposed at the end portions of the gas chamber close to the seal members, and accordingly, annular grease chambers for grease between the seal member and the ring member are formed, and it is possible to prevent grease shortage by the grease in the grease chambers.

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).
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 coeffient 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.

In an image encoder (1), a quantizer (11) makes a quantization-step size set for each of low-frequency subbands whose resolution level belongs to a predetermined resolution level coincide with a quantization-step size set for each subband to encode an original image having the resolution level as it is. A low-pass rate controller (17) provides a rate control for the bit rate of arithmetic code D16 in all code blocks in a low-frequency subband to be less than a predetermined target bit rate. A high-pass rate controller (18) provides such a rate control that the bit rate of arithmetic code D17 in all code blocks in other subbands than the low-frequency subbands will be less than a target bit rate, that is, a bit rate resulted from subtraction of a bit rate D18 having actually occurred in the low-frequency subbands from a final target bit rate.
摘要:
A wavelet encoding method and apparatus and a wavelet decoding method and apparatus for pictures. A input picture is split into plural tile pictures and wavelet transform is applied to input pictures on the tile picture basis to effect the encoding. For wavelet transform, pixels lying on the outer side of a given tile picture are symmetrically expanded and convolved. This enables marked memory capacity reduction, while eliminating constraint conditions for the number of times of wavelet splitting.
