摘要： A test pattern generation circuit outputs a test pattern during a clock phase adjustment period. A flip-flop circuit latches the test pattern at the fall of a shift clock and outputs it as a test pattern. A latch miss detection circuit outputs a latch miss detection signal indicating presence/absence of a latch miss generation according to the test pattern and a delay shift clock. A clock phase controller delays the shift clock according to the latch miss detection signal, thereby outputting a delay shift clock.

摘要： A test pattern generation circuit (100) outputs a test pattern (TP) during a clock phase adjustment period. A flip-flop circuit (110) latches the test pattern (TP) at the fall of a shift clock (SCK) and outputs it as a test pattern (Tpa). A latch miss detection circuit (130) outputs a latch miss detection signal (LM) indicating presence/absence of a latch miss generation according to the test pattern (TPa) and a delay shift clock (DSCK). A clock phase control section (120) delays the shift clock (SCK) according to the latch miss detection signal (LM), thereby outputting a delay shift clock (DSCK).

摘要： An inter-frame motion detector detects the presence or absence of motion between frames on the basis of judgment whether or not an inter-frame difference is not more than a set value. A vertical edge continuity detector calculates difference values between an object pixel and pixels above or below the object pixel in an inlaid picture, and detects whether or not there is horizontal continuity of an inter-field vertical edge on the basis of judgment whether or not the signs of the difference values are the same continuously over not less than a predetermined number of pixels, in the horizontal direction, including the object pixel. When it is detected that there is no motion between frames, and it is detected that there is horizontal continuity of the inter-field vertical edge, it is judged that a picture is in a completely still state.

摘要： A binarizer binarizes a video signal input from an A/D converter and a video signal output from a line memory using an average luminance value provided from a detection window video signal processor as a threshold value, and outputs a binary pattern. A reference pattern generater generates a plurality of reference patterns. An angle detector compares the binary pattern with each of the plurality of reference patterns, and outputs the angle of a matched reference pattern as angle information. An arc shape detector outputs the edge angle information of a picture based on a combination of the angle information of an interpolation scanning line including an object interpolation pixel and the angle information of interpolation scanning lines above and below the interpolation scanning line.

摘要： A vertical interpolation circuit interpolates an interpolated pixel with pixels located on upper and lower vertical positions, and outputs a vertical interpolated value. An oblique averaging part averages pixels obliquely located with respect to the interpolated pixel on the basis of an oblique edge angle signal, and outputs the result of calculation as an oblique average. An oblique difference absolute value operation part calculates the absolute value of the difference between the values of the pixels obliquely located with respect to the interpolated pixel on the basis of the oblique edge angle signal, and outputs the result of calculation as an oblique difference absolute value. A mixing part outputs the vertical interpolated value, the oblique average or a mixed value thereof as an interpolated pixel value on the basis of the oblique difference absolute value.

摘要： A video display monitor, such as a plasma monitor, which uses a subfield method which overlaps weighted multiple binary video images in a time base for display. The stable driving of a plasma display panel may be assured and display in the 256 grey-level may be maintained although vertical synchronizing frequency of the input video signal changes. A vertical synchronizing measurement unit measures the vertical synchronizing frequency of the video signal, and a subfield number adjustment unit adjusts the number of subfields in accordance with a measured vertical synchronizing frequency. The stable driving of the plasma display panel and display in grey levels may be assured by selecting a ROM table with an output bit width equivalent to the number of subfields to be output from multiple ROM tables used for converting the number of bits in the input signal.

摘要： In an image display apparatus, a video signal is divided for each field into a plurality of sub-fields, each of which is weighted according to the duration of time or number of pulses. The plurality of sub-fields are temporally superimposed for display, so that a grayscale representation is provided. A video signal for the current field is delayed by one field, and output as a video signal for the previous field. Based on the video signal for the current field and the video signal for the previous field, a luminance gradient of an image is detected. A difference between the video signal for the current field and the video signal for the previous field is calculated. Based on the calculated difference and the detected gradient, the amount of motion of the image is calculated by a detecting circuit. Based on the calculated amount of motion of the image, dynamic false contours are reduced by an image data processing circuit.
