    Abstract: An image signal processing apparatus and processing method for performing double-speed conversion of an image which has been subjected to telecine conversion. A first field is identified according to an image signal level difference value calculated for each detection pixel. In a field following the first field, a write-in pixel position shifted in the vector direction of the motion vector from the detection pixel is calculated. The calculated write-in pixel position is correlated to the motion vector and stored. Interpolation pixel data is calculated from the pixel data read out from the first field according to the stored write-in pixel position and the motion vector. The interpolation pixel data obtained is written into the write-in pixel position.

    Abstract: The nonlinear, deflection waveform used improve registration in a three picture tube projection television system is produced using interpolation of stored data setting points by first performing a reduced number of high-order interpolation calculations using the setting points and then performing low-order interpolation calculations either between two calculated high-order interpolated data points or between one of the calculated high-order interpolated data points and one of the setting points. This results in reducing the work load on the central processing unit in the registration system. In addition, a reduced bit-size requirement for the interpolation portion of the registration is obtained by storing registration data of a first bit size and then adding bits below the original LSB for the interpolation calculation prior to performing the digital to analog conversion.

    Abstract: An A/D converter (6) digitizes input video signals by using a clock pulse (53) from a VCO (4) of a PLL circuit (1). The frequency of the pulse (53) is fixed. After a pre-processing circuit (7) changes the number of scanning lines, the digital video signals are written in a field memory (10). From the momory (10), the video signals are read out by using a second clock pulse (63) generated from a PLL circuit (11). The frequency dividing ratio of a frequency divider (15) of the PLL circuit (11) is changed by means of a control signal. When the frequency dividing ratio is changed, the frequency of the clock pulse (63) is changed and the number of samples in 1H-section of the video signals read out from the memory (10) is changed. Since the number of the pixels in an effective video section of the written video signals is fixed, the ratio of the range of the 1H-section to that of the effective video section can be changed and, accordingly, horizontal size adjustment can be performed by changing the number of samples in the 1H-section on the reading-out side.

    Abstract: An image signal processing apparatus receives an image signal which has been generated by subjecting a telecine-converted image to double speed conversion. The image signal processing apparatus is operable to process the telecine-converted image signal by forming one film frame from four fields, a first field on the basis of a difference value calculated between pixel signal levels, and shifting the position of a detected pixel in a vector direction of a motion vector such that an amount of shift is progressively increased in accordance with a transition made from the identified first field to the subsequent fields.
