An image apparatus capable of improving a frame rate to prevent resolution in the predetermined area from decreasing and forming image signals outside the predetermined area has an area sensor in which a plurality of pixels is arranged in a matrix, a drive circuit unit, a read out circuit unit and a processing unit processing signals transferred from the read out circuit unit. The drive circuit unit and the read out circuit unit perform a first operation in which signals are simultaneously read out from N pixels in a first area of the area sensor (where N is an integer equal to one or more) and a second operation in which signals are simultaneously read out from M pixels in a second area except the first area of the area sensor (where M is an integer equal to two or more and always greater than N), the first and second read out operations are continuously performed in one frame period, and a first and a second signal obtained by the first and the second read out operations are continuously transferred from the read out circuit unit to the processing unit.

A multithreaded processor includes a thread ID for each set of fetched bits in an instruction fetch and issue unit. The thread ID attaches to the instructions and operands of the set of fetched bits. Pipeline stages in the multithreaded processor stores the thread ID associated with each operand or instruction in the pipeline stage. The thread ID are used to maintain data coherency and to generate program traces that include thread information for the instructions executed by the multithreaded processor.

A noise reduction system comprises an inputting unit inputting image data, and a noise reduction unit performing a process for removing noise of the image data input by the inputting unit. The noise reduction unit includes a representative value calculating unit calculating a representative value from the level values of a plurality of pixels in a predetermined direction, which include an observed pixel of the input image data, a representative value selecting unit selecting one representative value according to a predetermined condition from among a plurality of representative values which are calculated by the representative value calculating unit and correspond to a plurality of directions, and a replacing unit replacing the level value of the observed pixel with the representative value selected by the representative value selecting unit.

A transmission screen is capable of preventing the reduction of contrast in images due to external light such as emitted by internal lighting fixtures. The transmission screen includes a Fresnel lens sheet having a front surface facing the viewer and provided with Fresnel lens elements, and a shading sheet 13 placed contiguously with the front surface of the Fresnel lens sheet. The shading sheet 13 is provided with shading elements 22 for absorbing external light fallen on the front surface of the shading sheet 13 and reflected in a total reflection mode by the back surface of the Fresnel lens sheet facing a projection light source toward the viewer. Preferably, the shading elements 22 transmit at least external light fallen on the shading sheet at an incident angle θ satisfying a condition expressed by: θ<24+0.018×F, where θ is incident angle of external light that falls on the shading sheet, and F is the focal length of the Fresnel lens elements in millimeter.

An audio communication system including a communication server with an operator interface coupled to a network and one or more audio communication terminal clients coupled to the network. The communication server is advantageously implemented in a PC based system connected to a network. The network may include the internet. In operation the server may monitor the network for a client connection request issued by one of the audio communication terminal clients. A TCP / IP network connection is established between the communication server and a client after said communication server receives a client connection request. Once the connection is established the server displays an indication of client connection request through operator interface. Alternatively an indication of the client connection request may be presented to the operator. The operator then controls the server based on inputs to the user / operator interface. The operator may respond to the remote client either by speaking, by playing a pre-recorded message or by transferring the connection and / or connection request to another communication server. The system may be have a fault tolerant feature whereby the audio communication terminal clients attempt to connect with and alternate communication server if the initial server is not available.

Frequency characteristics of an optical low-pass filter (2) are set in such a way that a first false color passing rate indicative of the rate of frequency components passing through a frequency component region not lower than the Nyquist frequency fa for the lowest sampling frequency fs among the sampling frequencies in the longitudinal, the lateral, and the oblique directions for each color in an image sensor (5), i.e. a frequency component region lower than one half of the Nyquist frequency fs of the sampling frequency fs of the image sensor (5), is not higher than a specified value. An output image signal is created from a pixel signal created by the image sensor (5) so that N pixel signals (N is real number of 2 or above) created by the image sensor (5) correspond to one output image signal.

A resist composition contains a polymer-bound acid generator, specifically a polymer comprising recurring units derived from a sulfonium or iodonium salt having a polymerizable unsaturated bond and containing iodine in the linker between the polymerizable unsaturated bond and a fluorosulfonic acid. The resist composition offers a high sensitivity and improved CDU independent of whether it is of positive or negative tone.

A photographing apparatus and method prevent a resolution of a peripheral portion of an image from being degraded with a simple structure. These employ an in-focus state detector for detecting evaluation values for auto in-focus operation representing an in-focus state of an image from a first in-focus state detection region disposed on a center portion of the image, and at least one second in-focus state detection region disposed on a peripheral portion of the image, a flat subject determiner that determines whether a subject is flat based on the detection result of the evaluation values for auto in-focus operation, a flat subject focusing position calculator that calculates a final focusing position based on the evaluation values when the subject is determined as being flat, and a three-dimensional subject focusing position calculator that calculates a final focusing position based on the evaluation value when the subject is not flat.

An image processing apparatus and an image processing method for amplifying an image signal are provided without reducing an image size and without lowering a sense of resolution. An edge-direction detecting arithmetic section (2) detects an edge minimum direction from extracted Bayer data (BAY). An assigning arithmetic section (4) assigns a coefficient in which weighting is applied in the edge minimum direction of the extracted Bayer data (BAY) at a higher distribution ratio than other directions to a spatial filter kernel. In other words, the coefficient of the spatial filter kernel is changed in accordance with the edge minimum direction. A pixel adding arithmetic section (5) performs a sensitization process of extracted Bayer data (BAY). Therefore, it becomes possible to selectively perform a low-pass filtering process in the edge minimum direction. As a result, a sense of resolution can be prevented from being lost during the low-pass filtering process, and the sharpness of the outline of an image can be maintained.

An actuator which is actuated by an external input and also can remove noise caused by a high frequency by providing a low pass filter capable of preventing a particular high frequency through its mechanical structure. The actuator includes an external gimbal, an internal gimbal, and a connection axis which is disposed in an identical direction to an axis extended from the external gimbal. In this intake, the connection axis is provided between the external gimbal and internal gimbal whereby a not desired high frequency vibration may not be transmitted to a vibrated body provided in the internal gimbal. The actuator constructed as above does not need an electrical control and an additional part, and can be actuated by an external input, and also is highly productive and does not require an additional cost by providing a low pass filter with only comparatively simple change of a mechanical design.
