In the apparatus, the estimating section calculates the pixel value of the noteworthy pixel, which is to be converted into a binary value, based on other pixel values than that of the noteworthy pixel, and the binarizing section converts the multilevel value of the noteworthy pixel into a binary value.

Abstract: Interpolation of gradation levels of an image without degradation of the quality of the image is disclosed. The image is searched in the vertical direction from an objective pixel (Pt) to be subjected to the gradation level interpolation for a high-level pixel (Pvh) located closest to the objective pixel (Pt), and then searched in the horizontal direction from the objective pixel (Pt) for a high-level pixel (Phh) located closest to the objective pixel (Pt). A comparison is made between the high-level pixels (Pvh, Phh) to determine the distance from the objective pixel (Pt) to one of the high-level pixels which is closer to the objective pixel (Pt) as a high-level distance (Dhigh). Similar operation is performed to extract low-level pixels (Pvl, Phl), and a comparison is made therebetween to determine a low-level distance (Dlow). The gradation level of the objective pixel (Pt) is determined based on the high-level distance (Dhigh) and low-level distance (Dlow).

Abstract: A vibration-damping device capable of reducing the transmission of noise caused by a water pump of a hybrid vehicle, for example, to a vehicle compartment. The vibration-damping device includes a cushion member, a pump mounting member, and an elastic support member. The cushion member supports the pump, and includes holding portions each with a slit formed between an upper and lower surface thereof for insertion therein of end edges of a pump extension member that extends from the pump. The pump mounting member includes inverted L-shaped cross-section retaining portions provided on an upper surface thereof, the supporting portions being disposed between the retaining portions and the upper surface of the pump mounting member to retain the cushion member to the pump mounting member. The elastic support member engages a lower side of the pump to provide support against lateral deflection of the pump.

Abstract: All possible image levels of image data are input to tone conversion characteristics, and a tone jump included in the image after tone conversion is detected from the resultant output data. An A-type contour line and a B-type contour line constituting the contours of a target area for tone interpolation are obtained from the multi-tone image. The target area is then detected by checking the inclusive relationship between the A-type and B-type contour lines to extract at least one set of contour lines indicating the contour of the target area. In the target area, an area defined by the A-type contour line and the B-type contour line is divided into (N+1) divided areas, and N intermediate image levels are sequentially allocated to the N divided areas of the (N+1) divided areas.

Abstract: A cathode ray tube is provided with an electron gun having an electron lens including a large-diameter cylinder electrode and a small-diameter cylinder electrode composed of a large-diameter cylinder portion and a small-diameter cylinder portion, and at least the large-diameter cylinder portion of the small-diameter cylinder electrode is inserted in the large-diameter cylinder electrode thereby forming the electron lens. The small-diameter cylinder portion extending in the tube axis direction of the large-diameter cylinder electrode and connected to the large-diameter cylinder electrode is expanded or bulged, or the bottom portion of the large-diameter cylinder electrode is removed while only the electrode support portion connected to the large-diameter cylinder electrode is left, so that the electrode support fixed to the outer surface of the small-diameter cylinder portion of the small-diameter cylinder electrode can pass therethrough.

Abstract: A single-tube type projection display with high light efficiency includes phosphors of three primary colors formed on upper, middle and lower portions of a faceplate of a CRT. Images of three colors are projected on the phosphor layers, and a color picture is obtained by overlapping the three color images on the screen by the projection lenses.

Abstract: The present invention provides an improved technique for extracting contours in an image without waiting for processing of all the scanning lines in the image. Run-data on two boundary scanning lines, each representing the boundary coordinates at which the image changes, are stored in a run-data buffer. A contour extraction unit compares two sets of the run-data with one another to extract segment vectors and detect a set of closed-loop vectors defining a contour of a image area. Three registers in a working buffer store specific data representing the relationship between a starting point and a terminal point of each vector sequence and are used in detecting closed-loop vectors. A vector data memory stores vector data including coordinate values of start and end points of closed-loop vectors.

Abstract: A vibration-damping device with hydraulic damping has a base body, a cylindrical holder secured to the base body, and an outer cylinder press-fitted within the cylindrical holder. A vibration-damping rubber body provided with a main liquid chamber enclosing a damping liquid is disposed within the outer cylinder, and retains an inner cylinder. A thin rubber wall is disposed between the outer cylinder and the vibration-damping rubber body, and defines an auxiliary liquid chamber with the vibration-damping rubber body. This auxiliary liquid chamber communicates with the main liquid chamber by way of a throttled passageway. The cylindrical holder has a rib-like projection which radially outwardly project therefrom, and extends in a circumferential direction thereof. This projection defines a groove along an inner surface of the cylindrical holder.
