摘要： PURPOSE:To attain high speed seek operation by generating a pseudo track cross signal so as to calculate the seek speed when a pickup of a signal reproducing means detects an identification part formed with bit form of a track. CONSTITUTION:A track cross signal is outputted from a mono-clock circuit 142 of a signal processing circuit 140 while a difference signal S31 of an optical 2-split detection circuit is generated every time the pickup crosses a track and the signal is fed to a speed counter 151 of a present speed generator 150 via a switching circuit 145. The moving speed of the pickup is controlled in response to the pickup moving present speed outputted from the counter 151 to apply seeking. On the other hand, a correction counter 154 presetting the count of the counter 151 counts down in response to the output of a monostable multivibrator 144 triggered by a sum signal when the pickup crosses the identification part and a borrow signal is a pseudo track cross signal S154 and the speed control is applied without any hindrance even at the crossing of the identification part at the high speed pickup movement. As a result, the high speed seeking is also applied.

摘要： PURPOSE:To much more improve accuracy in the correspondence of plural images by constituting the title device of linked edge detection parts for a left image and a right image, a linked edge correspondent relation calculation part and a recorrespondence processing part, etc. CONSTITUTION:The image pickup device of a left image data input part 10L and that of a right image data input part 10R are set so that the positions in a vertical direction on the image may be coincident. The left image linked edge detection part 11L and the right image linked edge detection part 11R respectively detect the linked edge equivalent to a contour in terms of the respective images. The linked edge correspondent relation calculation part 13 calculates the corresponding linked edge between the left image and the right image from left image linked edge information RL, right image linked edge information RR and initial correspondence information COR from an initial correspondence processing part 12. The recorrespondence processing part 14 divides the respective images into small areas according to the linked edges of the respective images extracted because they are coincident and executes the correspondence processing of the respective images every small divided area.

摘要： PURPOSE:To attain optimum corresponding by detecting plural edge point continuing area in one of right and left pictures, limiting the existing range of an edge point in the other picture and executing the corresponding between the right and left pictures. CONSTITUTION:The plural edge point continuing areas, in which the edge point of one of the right and left pictures exists continuously in a vertical direction, are detected by an edge point continuing area detecting means 6. The existing range of the edge point in the other picture, which corresponds to the respective plural edge points to be included in the edge point continuing area, is limited in each edge point by a corresponding point existing range limiting means 7 on the basis of an output E of a first corresponding processing means 5. Further, on the basis of the result of the corresponding point existing range limitation, the corresponding is executed between the plural edge points, which are included in the plural edge point continuing areas, and the plural edge points of the other picture by a second corresponding processing means 8. Thus, even when the dispersion of brightness is partially generated by the influence of a noise, etc., the optimum corresponding can be executed between the right and left pictures.

摘要： PURPOSE:To reduce danger to erroneously detect an edge by judging that there is no edge in a subject picture element when the absolute value of different in brightness changing quantity in two directions to be mutually orthogonal is less than the prescribed brightness. CONSTITUTION:The input image of a TV camera, etc., to be inputted to an image input part 1 is inputted to a horizontal direction edge intensity Gx calculating part 2, a vertical direction edge intensity Gy calculating part 3, a left 45 deg. direction edge intensity Gl calculating part 4 and a right 45 deg. direction edge intensity Gr calculating part 5. Next, the intensity is reset to Gx1 and Gy1 based on the difference between the intensity Gx and Gy with using an edge intensity changing part 6 and the intensity is reset to Gl1 and Gr1 samely with using an edge intensity changing part 7. Thus, in the image input part 1, for example, an original picture as a detected body is read through windows (a)-(i) and detecting values Sa-Si signals of the brightness in the (a)-(i) are obtained. Then, the intensity Gx, Gy, Gl and Gr are calculated with using four expressions. Thus, even in case of the image, in which dark area are dotted, the erroneous detection as the edge is not executed.

摘要： PURPOSE:To avoid an edge cut and unnecessary edge extraction and to stabilize the edge extraction by using the differentiating value of an observed picture element and a neighboring picture element and the direction of differentiation and updating the differentiating value of the observed picture element with being repeated. CONSTITUTION:An edge detecting circuit is composed of image memories 1, 3, 4 and 6 a differentiating circuit 2, a selector 7, an edge updating circuit 8 and an edge extracting circuit 5. Thus, an input image stored in the memory 1 is differentiated by the differentiating circuit 2 and the obtained differentiating value is written through the selector 7 to the memory 3. Then, the differentiating direction is directly written to the memory 4. Next, the data of the memories 3 and 4 are read by the edge extracting circuit 8 and the new differentiating value is computed with using the differentiating value and differentiating direction of the read picture element and neighboring picture element. Then, this value is written through the selector 7 to the memory 3. This update operation is repeated only by a designated number. Then, when the threshold of the read picture element and neighboring picture element is larger than the threshold set in advance '1' is written through the circuit 5 to the memory 6 and when it is smaller, '0' is written.
