摘要： A lens barrel comprises an optical system provided within a main body of the barrel, an operation ring used for a photographer to operate the optical system, driving means, used for an electric drive, for generating a driving force transferred to the operation ring via a driving force transfer member, and a rotation restricting stopper for restricting a range of rotation of the operation ring. The rotation restricting stopper is movable between a position for restricting the range of the rotation of the operation ring and a position where the range of the rotation is not restricted, and substantially simultaneously restricts a range of rotation of the driving force transfer member in the position for restricting the range of the rotation of the operation ring.

摘要： Provided is an image processing apparatus in which high-quality image representation is possible at very low cost even if high image resolution is obtained. The apparatus includes a first halftone processor for pseudo-halftoning an 8-bit image signal to a 4-bit image signal, an image processor, which comprises a color correcting unit, a converter, a resolution converter, a spatial filter and a gamma corrector, for processing the 4-bit image signal, a second halftone processor for pseudo-halftoning the image-processed 4-bit image signal from the image processor to one bit, and a recorder for outputting an image based upon the 1-bit signal. In another aspect, the amount of calculation required for highly precise color correction processing inclusive of image-quality adjustment processing is large. This has made it necessary to rely upon hardware such as an ASIC, a consequence of which is higher cost. Accordingly, a first halftone processor converts input 8-bit data to 4-bit data and a color correcting unit performs color correction processing, using a LUT conversion, of the 4-bit data. Since the LUT is updated in dependence upon adjustment of image quality performed using a control panel, it is possible for the adjustment to be reflected in real time.

摘要： In an image processing apparatus in which digital data of a certain number (m) of levels are converted into digital data of a larger number (n) of levels, then subjected to certain desired editing processing, and again digitized to data of the original number (m) of levels. The redigitization to m levels is conducted by determining the average density of a predetermined area, utilizing data of pixels already redigitized to m levels, and redigitizing the data of n levels into m levels, utilizing the average value. This process significantly reduces the amount of data processing required without formation of an unpleasant texture on the image resulting from errors in digitization.

摘要： There is disclosed an image processing apparatus for intermediate tone processing of an image signal into a binary signal, capable of providing a reproduced image with excellent resolution and gradation with a simple structure, and without the periodic texture inherent to the conventional error dispersing method or average density conserving method. The disclosed apparatus determines the average density of an already binarized predetermined image area, binary digitizing the image signal of a contemplated pixel, utilizing the determined average density as the threshold value, and distributing the error, generated in the binary digitization, to the image data of plural pixels to be digitized thereafter with certain distribution factors. The distribution factors are randomly changed according to random numbers generated by a generator, so that the reproduced image is free from periodic patterns resulting from periodic distributions of the errors.

摘要： A lens barrel comprises a fixed barrel; a photographing lens which requires a first torque for driving the lens along the fixed barrel; and a surface wave motor including a fixed body and a moving body which is rotated relative to the fixed body by excitation for driving the lens. When the motor is not excited, a second torque is exerted between the moving body and the fixed body to prevent the relative rotation. The moving body is caused to rotate by a torque greater than the second torque. A friction generating device provided between the fixed barrel and the fixed body exerts a third torque to prevent relative rotation between the fixed barrel and the fixed body. The fixed body can rotate with respect to the fixed barrel only when the fixed body is caused to rotate by a torque greater than the third torque. A manual operation member drives the photographing lens by a manual operation; and a friction clutch provided between the manual operation member and the fixed body exerts a fourth torque. The manual operation member can rotate with respect to the fixed body only when caused to rotate by a torque greater than the fourth torque.
