Abstract: PROBLEM TO BE SOLVED: To enlarge or reduce an image at an arbitrary conversion rate. SOLUTION: A residue circuit 11 outputs a phase variation component Pd supplied from a specific device and the decimal part of the sum of the value of a register 12 to the register 12. An approximation circuit 13 outputs a filter select signal Pi whose phase (x) corresponds to a filter coefficient set corresponding to the phase closest to the value of the register 12 to a coefficient memory 1A. Thus, an optimum filter coefficient set among a specific number of filter coefficient sets is selected for the interpolation of specific pixel data. Then product sum operations between the four filter coefficient sets and four pixel data are performed by multipliers 3-1 to 3-4 and an adder by a Cubic approximating method to calculate an interpolated value of pixels.

Abstract: PURPOSE:To perform the parallel processing of picture element data in every one horizontal period even in the case of an image signal having a short horizontal blanking period. CONSTITUTION:Picture element data is inputted from an input terminal in the horizontal period and is held in an input buffer 120 for a prescribed time and is transferred to a shift register 130 after reserving a prescribed blanking period. This input picture element data is transferred from the shift register 130 to operation parts 151 to 153 in the next blanking period, and the operation processing is performed in the next horizontal period. After transfer of input picture element data in the next blanking period, data of the operation result is transferred to the shift register 130. In the next horizontal period, the result data is transferred to an output buffer 140 simultaneously with transfer of input picture element data. The output buffer 140 holds the result data and outputs this data synchronously with a desired output signal by reduction of the blanking period or the like.

Abstract: PURPOSE:To execute the fault diagnosis of a memory, etc., and the detection of a fault part by a host computer by providing a control part for generating a load signal to a register by a request from the host computer. CONSTITUTION:A host computer, first of all, sets an image memory and a look-up table 21 to a color to be tested. The image memory is painted out in this color, and all pixels of the image memory are set so as to designate a specific address of the look-up table 21. To the specific address of the look-up table 21, an RGB code of a color to be tested is set, and to other address than said address, other code is set. In such a state, in a blanking period, a load signal is supplied to a register 25, and the register 25 inputs output data supplied to a D/A converter. By reading out the contents of this register 25 by the host computer, whether the set RGB code is obtained or not is decided. In such a way, a fault part can be detected easily.

Abstract: PROBLEM TO BE SOLVED: To generate an image of an interpolating frame with higher accuracy.
SOLUTION: A motion compensating part 23 and a motion compensating part 24 perform motion compensation by using input images of temporally previous and following frames of an interpolating frame to generate a previous interpolating image and a following interpolating image. An image generating part 25 outputs the pixel of the previous interpolating image of the same position as a pixel under consideration when the previous reference pixel of the input image of the previous frame obtained by moving the pixel under consideration only for the motion of a motion vector is within an effective region and also when the following reference pixel of the input image of the following frame obtained by moving the pixel under consideration only for the motion of the motion vector is not within the effective region by sequentially defining the pixel of an interpolating image of an interpolating frame to be generated from now on as the pixel under consideration, and outputs the pixel of the following interpolating image of the same position as the pixel under consideration as a pixel under consideration when the previous reference pixel is not within the effective region and also when the following reference pixel is within the effective region. This invention is applicable to an image processing device.

Abstract: PROBLEM TO BE SOLVED: To individually execute a plurality of different signal processings using predetermined kinds of control signals. SOLUTION: A main signal propagating part 263 propagates a main signal from a signal input part 261 to a signal output part 265, by sequentially executing N signal processings using the control signals for the main signal input to the signal input part 261. A control signal generating part 262 generates control signals in the form corresponding to the signal processing executed by a first signal processing part 263-1 of the main signal propagating part 263, and supplies them to the first signal processing part 263-1. When processings are sequentially executed by a second signal processing part 263-2 or an N signal processing part 263-N of the main signal propagating part 263, respectively, a control signal propagating part 264 sequentially converts the control signals generated by the control signal generating part 262 into the forms corresponding to signal processing to be executed by the main signal propagating part 263, and sequentially supplies them to the main signal propagating part 263. This device is applicable to a television system. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To reduce steps of a program. SOLUTION: Bit length of an operand with longer bit length among a first operand or a second operand is loaded on a repeat counter 52, the bit length of an operand with shorter bit length is loaded on a bit counter 53 and the operands are decreased as well as a repeat processing by a sequencer 50. Repetition frequency of the repeat processing is set as the counted number of the repeat counter plus one. After a value of the bit counter 53 becomes zero, when the operand with shorter bit length is a complement of two, its MSB is supplied to a full adder and when the operand is a straight binary number, a value zero is supplied to the full adder. In addition, in the last clock of the repeat processing by the sequencer 50, the operand with longer bit length is the complement of two, its MSB is supplied to the full adder and when the operand is the straight binary number, the value zero is supplied to the full adder.
