There is provided a digital photographic instrument comprising an edge enhancing section which enhances the edge of image data. The instrument determines whether a focus is good or bad and adjusts the degree of edge enhancement in the edge enhancing section according to the result of the determination, thereby giving a sharp photograph. The instrument also shortens time required for focusing by complementing an autofocusing mechanism.

A plurality of inductors are formed by connecting linear patterns formed in different surfaces of a substrate respectively by means of holes, forming a plurality of electrically neutral surfaces in areas not including the linear patterns on different surfaces of the substrate, and furthermore by forming electrically neutral holes connecting the electrically neutral surfaces to each other at positions between the plurality of inductors to affect the coupling between inductors.

A switch having two planes opposing and substantially in parallel to each other and switching between a first electrode and another electrode by pressing down one of the planes. Contact point patterns each made of a conductive material having a specified shape are provided on one of the planes. Stripe electrode patterns in which the first electrode and the other electrode are alternately positioned are provided on the other plane in a region where the contact pattern on the one plane is superimposed when that plane is pressed down.

A distributed constant type multiple-line circuit is described which comprises a dielectric block (60) having shield conductors (62,64) on its rear surface and all the peripheral side surfaces, a central conductor (1) extending in the block in the front-to-rear thickness direction at the central portion thereof, a first plurality of conductors (2-5) positioned around and parallel to the central conductor and inductively coupled therewith, and a second plurality of conductors (2'-5') positioned nearby and parallel to the first conductors and inductively coupled therewith, respectively. The length of the central conductor is equal to one quarter of the wavelength of the central frequency (f.sub.1) in a frequency band, and the rear end thereof is isolated with the shield conductor on the rear surface of the block. Each of the lengths of the first conductors is equal to one quarter of the wavelength of a predetermined frequency (f.sub.2 -f.sub.5) in the frequency band, and the rear ends thereof are shorted with the shield conductor on the rear surface of the block. Each of the lengths of the second conductors is equal to that of the corresponding one of said first conductors, and the rear ends thereof are isolated with the shield conductor on the rear surface of the block. An input signal (S.sub.IN) iS input to the front end of the central conductor, and signal components of frequencies (f.sub.2 -f.sub.5) are respectively output through the first conductors from the front ends of the second conductor.

In order to efficiently and steadily remove a frequency-fluctuating interference wave, for instance, a leakage wave of a household electronic oven, intermixed into a received wave for communication, adaptively to the frequency deviation and the frequency fluctuation of the interference wave, a rejection band component included in the received wave applied onto a circulator an output terminal of which is connected with a variable band rejection filter is reflected from the output terminal on which impedance mismatch is caused by zero-impedance presented by the rejection filter on the basis of absorption of input wave and applied to a detector through the circulator again, in response to a detection output of which a so-called mountaineering control is effected on the variable band rejection filter for shifting the rejection band, so as to maximize the detection output of the detector adaptively to the frequency deviation and the frequency fluctuation of the interference wave.

In order to efficiently and steadily remove a frequency-fluctuating interference wave, for instance, a leakage wave of a household electronic oven, intermixed into a received wave for communication, adaptively to the frequency deviation and the frequency fluctuation of the interference wave, a rejection band component included in the received wave applied onto a circulator, an output terminal of which is connected with a variable band rejection filter, is reflected from the output terminal on which impedance mismatch is caused by zero-impedance presented by the rejection filter on the basis of absorption of the input wave and applied to a detector through the circulator again, in response to a detection output of which a so-called peak-keeping control is effected on the variable band rejection filter for shifting the rejection band, so as to maximize the detection output of the detector adaptively to the frequency deviation and the frequency fluctuation of the interference wave.

For removing the variation of resonant frequency of the 1/4 .lambda.g coaxial resonator, which is caused by the external connection as a result of conventional capacitive coupling, a 1/4 .lambda.g line having both ends opened is coupled to the 1/4 .lambda.g resonant line having one end shorted through distributed inductive coupling, so as to provide a basic structure of the dielectric resonator of the invention, which can be arranged in usual various types of circuits such as filters, multiplexers and the like with excellent and stable performances.
