The image pickup device includes a solid-state image pickup element having a pixel part including an effective pixel area to be irradiated with light, and a light-shielded pixel area where irradiation of light is shielded, a vertical scanning circuit, a horizontal scanning circuit, and an output circuit, a controller that controls the solid-state image pickup element such that the pixel signals outputted from the pixels arranged in the light-shielded pixel area or the pixel signals outputted from the pixels arranged in the effective pixel area are outputted from the output circuit, a control signal generator that generates a predetermined control signal, a noise component detector that detects noise, and a noise corrector that corrects noise contained in the pixel signals from the effective pixel area based on a noise component detected by the noise component detector, wherein the control signal generator generates different control signals at predetermined timing.

摘要： Data is updated while making sure that one logically meaningful data group is set as the unit of data update. A host computer requests a first disk controller a data input/output request to/from a logical volume of a first disk drive. When the request is an update request, requested update data is stored in the first logical volume, by a first control. The update request is sent to a second disk controller and is temporarily accumulated there, when information indicating a group to which the update data belongs is attached to the update request. When the first disk controller finishes executing every data input/output request that is designated by information indicating to which group the update data belongs, the accumulated update data for those belonging to the same group to which group update data belongs is retrieved and stored in a second logical volume.

Thus, a content of processing for the capsule endoscope 3 is changed over, and a selection controller C1 selects a receiving antenna for an image receiving period from receiving antennas A1 to An.

摘要： Each of detecting circuits 36a, 36d, 36f, and 36h detects a key signal such as a horizontal synchronization signal, a vertical synchronization signal, a capsule ID, a WB coefficient, and error information, i.e., a key signal superposed on RF signals received by an RF receiving unit 33. Each of determining units 36b, 36c, 36e, 36g, and 36i determines whether an image is valid or invalid based on the result of detection. A recording deciding unit 36k decides whether to record the image information in a storage unit 35 or not based on the result of determination. Thus, a receiving apparatus 3 can stop recording the image information received when a trouble occurs, thereby preventing defective images from mixing into the recorded image information, and preventing a recorded image size from becoming large, whereby necessary images can be recorded within a predetermined examination time.

摘要： An image denoising system and method of implementing the image denoising system is described herein. Noise is decomposed within each channel into frequency bands, and sub-band noise is propagated. Denoising is then able to occur at any node in a camera pipeline after accurately predicting noise that is signal level-dependent, frequency dependent and has inter-channel correlation. A methodology is included for estimating image noise in each color channel at a sensor output based on average image level and camera noise parameters. A scheme is implemented for detecting a peak-white image level for each color channel and predicting image level values for representative colors. Based on a noise model and camera parameters, noise levels are predicted for each color channel for each color patch and these noise levels are propagated to the denoising node. A three dimentional LUT correlates signal level to noise level. Then, a denoising threshold is adaptively controlled.

摘要： To realize a technique for calculating a positional relationship between a target coordinate axis fixed with respect to a detection target and a reference coordinate axis defined independently of motion and the like of the detection target, a first and a second linear magnetic fields in known directions on the reference coordinate axis are generated and a direction of the first and the second linear magnetic fields on the target coordinate axis are detected by a magnetic field sensor installed in an capsule endoscope (2), which is the detection target. By comparing the directions, which are detected by the magnetic field sensor, of the first and the second linear magnetic fields on the target coordinate axis and the known directions of the first and the second linear magnetic fields on the reference coordinate axis, a deviation of the direction of the target coordinate axis with respect to the reference coordinate axis is detected. Further, a positional relationship of an origin of the target coordinate axis with respect to an origin of the reference coordinate axis is calculated by generating diffuse magnetic field, other than the first and the second magnetic fields, whose strength decreases corresponding to a distance.
