Abstract: PURPOSE:To accurately measure the size of a necessary part of a two-dimensional object of measurement in a short time by measuring an image roughly by a two-dimensional sensor and then taking a fine measurement by a linear sensor. CONSTITUTION:A composite image sensor is so constituted that an image of an object 11 is formed on the two-dimensional sensor 6 through a lens system 10 and the same image is formed on the linear sensor 4 by using a means such as a beam splitter 9; and signals from the sensors 6 and 4 are inputted to an image processing system 5. Consequently, the image signal from the sensor 6 is processed 5 to detect feature points, etc., of the image 12 of the object of measurement within the visual field 14 of the two-dimensional sensor. Then they are compared with previously given parameters to calculate the position of a measurement part 15 which needs to be accurately measured in the image 12 from said image processing signal.

Title: Write timing compensating system of magnetic recording device
Inventor: MURAKAMI YOUICHI
IPC: G11B20/18
Filed: 1980-06-23
Abstract: PURPOSE:To reduce the error caused in a back read mode, by giving a control so that the timing compensating quantity when a high recording density changes to a low density becomes larger than the compensating quantity of the contrary case in a writing mode. CONSTITUTION:The write input applied to an input IN receives a timing compensation from a flip-flop FF to be sent to an output OUT. At the same time, the density of displacement is detected by detectors D1-D3 for the write input. When the recording density has no change, a writing is carried out by the reference clock CL0 via an AND circuit A2, an OR circuit O and an FF. In case when the density of displacement of the signal has a change to a low level, an output emerges at the detector D1; while an output emerges at the detector D3 when the density of displacement is changed to a high level. Then a writing is carried out to the gained clock signal CLl and delayed clock signal CLd each with a change given to the timing of displacement. As a result, the error caused in a back read mode can be reduced.
