An image-type intubation-aiding device comprises a small-size image sensor and a light source module both placed into an endotracheal tube to help doctors with quick intubation. Light from light emission devices in the light source module passes through a transparent housing and is reflected by a target and then focused. The optical signal is converted into a digital or analog electric signal by the image sensor for displaying on a display device after processing. Doctors can thus be helped to quickly find the position of trachea, keep an appropriate distance from a patient for reducing the possibility of infection, and lower the medical treatment cost. Disposable products are available to avoid the problem of infection. The intubation-aiding device can be used as an electronic surgical image examination instrument for penetration into a body. Moreover, a light source with tunable wavelengths can be used to increase the spot ratio of nidus.

For certain medical images, it is important and / or required that a user view all of a medical image at full resolution so that minute, but important, indicia in the medical image are not missed. A computing systems monitor the portions of the medical image that are displayed on the display device, notates those portions that have been displayed at full resolution (or other user-defined display parameters), and provides the user with information indicating portions that have not been viewed at full resolution and / or provides information indicating for which images of a multiple image examination full pixel display has been accomplished. The process reduces the possibility of missing an abnormality in a medical image due to the viewer not viewing a portion of the image at full resolution or using other user-defined display parameters.

System-directed checkpointing is enabled in otherwise standard computers through relatively straightforward enhancements to the computer's memory controller. Different embodiments of the invention can be used to support: local and remote post-image checkpointing using a memory-resident address buffer for storing the addresses of modified data blocks, either with or without requiring the processor caches to be flushed at each checkpoint; local and remote post-image checkpointing using either memory- or I / O-resident buffers for both the addresses and the data associated with blocks modified since the last checkpoint and supporting background buffer-to-shadow copying; remote and local post-image checkpointing using bit-map memories thereby avoiding the need for either address or data buffers while still supporting background data copying and either with or without requiring caches to be flushed to effect a checkpoint; local post-image checkpointing using a two-bit-per-memory-block state memory that eliminates the need for any data to be copied from one memory location to another; and pre-image local checkpointing again either with or without requiring caches to be flushed for checkpointing purposes. Since most of these implementations have advantages and disadvantages over the others and since similar mechanisms are used in the memory controller for all of these options, the controller can be implemented to support all of them with a hardwired or settable status register defining which is to be supported in a given situation. Alternatively, since some of these implementations require somewhat less extensive memory controller enhancements, the controller can be designed to support only one or a small subset of these embodiments with a correspondingly smaller perturbation to its more standard implementation.

A reference image and a target image for image inspection are displayed side by side in a monitor. The reference image is taken in approximately identical shooting condition to the target image for the image inspection, and corrected with a reference correction parameter. The reference correction parameter and the reference image are stored in a memory. The target image for the image inspection is corrected with the reference correction parameter. The operator determines image quality while comparing the reference image to the target image for the image inspection. When the image quality is unsatisfactory, the target image for the image inspection is corrected. When the correction parameter is changed during the image correction, the changed correction parameter is used for correcting the next image instead of the reference correction parameter.

An image inspection apparatus for inspecting a scanned image of an output image includes an inspection reference image generator to generate an inspection reference image; an image inspection unit to determine a defect by comparing a difference between the inspection reference image and the scanned image with a threshold; a threshold determiner to determine the threshold; and a defect range determiner to determine a range of defect level of a plurality of artificial defects. Based on a difference computed for a defect selected from the plurality of artificial defects, the threshold determiner determines a threshold to be compared with the difference of the selected defect. The defect range determiner conducts a defect determination for the scanned image at the upper and lower limits for a threshold to determine a range of defect level of the plurality of artificial defects.

A method for detecting phase features or phase defects on photomasks for optical lithography is described. The asymmetric imaging behavior through focus of defects or features with a phase other than 0° or 180° is used to distinguish them from other features on the mask. The mask is inspected at equally spaced positions about an optimum focus in both positive and negative directions. The images are subtracted from one another to produce a differential image of the mask. While opaque features as well as transmitting features at 0° and 180° behave identically at positive and negative defocus, thus leading to a zero-valued differential image, the focus asymmetry of phase defects and features produces a non-zero differential image from which these phase defects and features can be located. By comparing the locations on the mask for which a non-zero differential image is obtained with the designed data for the mask, the phase defects can be sorted from the phase features and the absence of phase features can be detected. Additional image processing can be applied to verify the integrity of the phase features. The differential image inspection technique can be implemented on existing optical inspection tools by employing a two-pass inspection performed at positive and negative defocus in sequence. In addition, a new apparatus with parallel inspection optics is described for inspecting the mask at positive and negative focus simultaneously.

An image inspection device to automate and simplify inspection of an output image. A paper discharge tray of a printer is a different color from paper. A CCD camera is disposed above a paper discharge portion of the printer, at which paper is discharged, and can capture the whole upper face of the paper discharge tray. When, directly after a state in which there is no paper on the paper discharge tray, a print job is received and a first print-processed sheet is outputted to the paper discharge tray, a CPU controls the CCD camera to capture the paper discharge tray in this state. Captured image data including the paper is acquired, corrections are applied to the captured image data and to original image data by image processing, and image characteristics thereof are made substantially the same. Thereafter, the outputted image is inspected by comparison of the two data sets.

In a face authentication unit of the portable telephone, the face image checking part checks the face image of the person to be authenticated, which is acquired by a face image acquiring part through a photographing unit, with face feature information contained in a face feature DB of the storage unit and calculates the matching degree. A threshold value determining section determines the threshold value by searching the evaluation DB based on the position information of the own device acquired by the position information acquiring section through the GPS receiver. An authenticating section compares the matching degree calculated by the face image checking section and the threshold value determined by the threshold value determining section, and determines success and failure of the face authentication.
