Abstract: The signals are generated by a charge-coupled solid-state image sensor (CTE) having a picture pick-up member (PD) with picture pick-up elements (P) which are senstive to picture information and which are arranged in rows and columns in a raster and with a parallel-in, series-out shift register member (SRD) for obtaining, after a picture information integration period the line and field-sequentially built-up picture pick-up signals (PS 1 , PS 2 ) at the device outputs (CT 1 , CT 2 ) after a parallel information transfer from the pick-up member (PD) and a series-sequential shift in the shift register member (SRD). If one shift register (SR) is effectively operative for at least two rows (R) of picture pick-up elements (P), the shift register output (ST) is coupled via a switching circuit (SC1) to the device outputs (CT 1 , CT 2 ), whilst the switching frequency is equal to half the register element shift frequency (1/2FP). In the case of equal numbers of device outputs (CT 1 , CT 2 ) and shift registers (SR1, SR2) these are coupled together and the information is distributed row-wise in a punctuated manner over the shift registers (SR1, SR2) after the parallel information transfer. The result is an interlaced and punctuated pick-up signal generation. For a colour picture recording a colour mosaic filter may be arranged in front of the picture pick-up member (PD).

Abstract: A system is disclosed wherein a plurality of discs (11) in a stack are accessed using a vertical head array including two servo heads (13), one located at or near each end of the disc stack. In order to exactly center any given data head over a desired data track location in the disc stack, the error distance of the given data head relative to the data track can be determined by combining propor­tions of the two servo head signals from the top and bottom servo heads (131), their proportions being based on the vertical distance of each of the servo heads from the given data head which is to be exactly centered over a data track. If the servo distance from the disc edge is represented by S1 and S2, and the vertical distances from the head to the center of the servo heads is represented by Y1, Y2 then the general formula for calculating the error correction for centering the typical data head is E c =1/Y1+Y2 × (S2Y1+S1Y2).

Abstract: A camera is provided wherein accidental manual rotation of a thumbwheel (1) to advance film in the camera is prevented whenever the shutter is opened to take a picture. According to the invention, when a trigger button (57) is manually depressed, a high energy member (19) in a cocked position is unlatched to permit the high energy member (19) to travel a first increment to momentarily open the shutter. The film advance thumbwheel (1) remains locked by a locking member (9) to prevent any rotation of the thumbwheel (1). When the trigger button (57) is manually released to return to its original position, the trigger button (57) disengages from the high energy member (19), permitting the high energy member (19) to travel a second increment. During its second increment of travel, the high energy member (19) moves the locking member (9) out of locking relation with the thumbwheel (1). Thus the thumbwheel cannot be operated to advance film until picture-taking is completed.
