摘要： The present invention relates to a method of converting 2D images into 3D images by producing from a 2D image signal a main image signal and a sub-image signal delayed from the main image signal. In the present invention, a temporary field delay from the main image signal to the sub-image signal is found on the basis of data related to the movement in the current field of the main image signal (a first step). A target field delay is then found on the basis of the temporary field delay found in the first step (a second step). A true field delay used in the succeeding field is found on the basis of the target field delay found in the second step and the true field delay used in the current field (a third step).

摘要： A video signal processing circuit is incorporated in an IC for camcorder in which a camera signal outputted from a CCD image sensor is processed in a digital manner such that luminance and color signals can be outputted. In the IC, a vertical interpolation circuit produces two kinds of vertically interpolated data on the basis of a digital camera signal of one channel within an image area being set by an electronic zoom function. A YC separation circuit receives the two kinds of vertically interpolated data, and an output of the YC separation circuit is applied a horizontal interpolation circuit or an RGB composition circuit If the YC separation output is applied to the horizontal interpolation circuit, the same outputs two kinds of horizontally interpolated data upon which three primary color signals are composed by the RGB composition circuit. If the YC separation output is applied to the RGB composition circuit, the horizontal interpolation circuit produces two kinds of horizontally interpolated data on the basis of three primary color data outputted by the RGB composition circuit.

摘要： In an image signal processing device, a subtractor circuit 4 and an absolute value calculating circuit 6 calculate the absolute value of the difference between the image signal of the previous frame fed from a frame memory 1 and the image signal of the current frame, and a subtractor circuit 5 and an absolute value calculating circuit 7 calculate the absolute value of the difference between the image signal of the previous-previous frame fed from a frame memory 2 and the image signal of the previous frame. An adder circuit 8 adds together the thus calculated absolute values of the differences between those image signals to calculate the degree of motion, on the basis of which a gain setting circuit 9 sets a gain. The output from the subtractor circuit 4 is multiplied by this gain to generate a noise component.

摘要： In a motion detecting device, with respect to a target pixel for which detection of motion is going to be performed, the threshold value to be used by comparator circuits 9 and 10 is varied based on the difference of image data between two pixels vertically adjacent to the target pixel. The comparator circuit 9 compares the difference, between two fields, of the image data of the target pixel with the threshold value, and the comparator circuit 10 compares the differences, between two fields, of the image data of the two pixels vertically adjacent to the target pixel with the threshold value. An adder circuit 12 adds together the comparison results with weights assigned thereto, and the detection of motion is performed based on the resulting sum.

摘要： In a first method of converting two-dimensional images into three-dimensional images according to the present invention, when the movement of a main image is fast, a main image signal is written into field memories for each field. When the movement of the main image is slow, the main image signal is written into the field memories at intervals of a predetermined number of fields. An image to be read out as a sub-image from the field memories is determined on the basis of the speed of the movement of the main image.
