An image processing apparatus includes a contour-candidate-edge detecting unit that detects, as contour candidate edges, edges based on a gradient magnitude of each pixel in a target image; a contour-edge detecting unit that detect contour edges by performing thresholding on gradient magnitudes of the contour candidate edges; an interpolation-line generating unit that generates interpolation lines for connecting end points of respective end-point pairs based on gradients of pixel values between the end points while each of the end point pairs is made up of an end point of an identical contour edge as a connection base and an end point of a different contour edge as a connection destination; and a contour-edge interpolating unit that selects one of the interpolation lines based on the gradients of pixel values on the interpolation lines and interpolates a contour edge between the end points with the selected interpolation line.

An image processing apparatus includes: an area extracting unit that extracts a candidate area of a classification target area in which a pixel value does not correspond to a three-dimensional shape of an imaging target based on pixel values of an intraluminal image acquired by imaging the inside of a lumen or information of a change in pixel values of peripheral pixels; and an area classifying unit that classifies the classification target area out of the candidate area based on the pixel values of the inside of the candidate area, a boundary portion of the candidate area, or a periphery portion of the candidate area.

An image processing apparatus includes an identification criterion creating unit that creates an identification criterion so as to enable identification of specific regions in a target image to be processed that is selected in chronological order from among images constituting a set of time-series images; includes a feature data calculating unit that calculates the feature data of each segmented region in the target image to be processed; and includes a specific region identifying unit that, based on the feature data of each segmented region, identifies the specific regions in the target image to be processed by using the identification criterion. Moreover, the identification criterion creating unit creates the identification criterion based on the pieces of feature data of the specific regions identified in the images that have been already processed.

In this AG-AND type flash memory, a layered bit line configuration where a memory array is divided into a plurality of sub blocks, new main bit lines are allocated so as to correspond to each sub block, and a main bit line is selectively connected to a global bit line in an upper layer via a switch is adopted, so that charge sharing write-in is carried out between two main bit lines. Accordingly, write-in of data into the flash memory can be carried out with low power consumption, and the threshold voltage can be controlled with precision.

A DLL clock control circuit determines whether or not an operating frequency is a low frequency satisfying a prescribed condition, based on signals received from a DLL circuit and a READ control circuit. When the DLL clock control circuit determines that the operating frequency is a low frequency, the DLL clock control circuit outputs a DLL clock received from the DLL circuit if a first signal to be activated in response to a READ command is activated, while when determining that an operating frequency is not a low frequency, outputting a DLL clock received from the DLL circuit if a second signal to be activated in response to an ACT command is activated. As a result, a semiconductor memory device can guarantees a data output operating in data reading and can reduce power consumption during active standby.
