摘要： An imaging apparatus in which the influence of the movement of hands and of the motion of an object to a high resolution picture image is reduced is provided. Picture image light from the object passes through an optical system (33) and light-transmitting domains (L) of a color filter provided at the light incident side of an imaging device (34). The light-transmitting domains (PD) transmit only predetermined chromatic lights of the picture image light to input to corresponding photo-receiving domains (PD) of the imaging device (34). The imaging device (34) is a two-picture element mixed reading type device. In a high resolution mode, an image forming point of the picture image light is moved to two places in parallel and the picture image light is formed at each image forming point to image the picture image light. Then, the signal processing circuit (44) combines the two original picture image signals whose image forming points during the imaging operation are different to generate a single output picture image signal. Thereby, an equivalent imaging time in imaging a single output picture image may be shortened.

摘要： In a multi-track magnetic signal reproducing apparatus, a plurality of MR heads including MR (Magneto Resistance Effect) elements (2-1 to 2-N) are provided correspondingly to tracks on a magnetic tape. At the time of reproduction, constant current from a constant current power supply (1) is sequentially supplied as pulse-shaped current for detecting a signal to each MR element by a switching operation by switch (3) in response to a prescribed clock signal (CL1), and output voltage from each MR element related to reproduction of a magnetic signal on a corresponding track is sequentially provided to one input side of a differential amplifier (4). In differential amplifier (4), the offset voltage of each MR element provided to the other input side and the above-described output voltage are differentially amplified and only voltage due to the reproducing magnetic signal of each track is accurately extracted. Accordingly, the supply of pulse-shaped current effectively suppresses increase in the amount of consumption current regardless of the number of tracks on the tape (or the number of heads), and since amplifier (4) is shared between the tracks, the number of necessary terminals for such a multi-track MR head is reduced.
