Title: Production circuit for optical head control signal
Inventor: TAKEI TOSHIJI
IPC: G02B7/28
Filed: 1986-04-09
Abstract: PURPOSE:To simplify the constitution and also to contrive the cost reduction by detecting scratches with the signal used by a tracking error generating circuit and switching the output of a simple holding circuit. CONSTITUTION:When the beams are gradually eroded by scratches, a spot symmetrical shadow is produced. Thus a signal S12 is produced with the bit modulation component applied onto the scratch signal. At the same time, a signal S13 of adverse polarity is also produced. The inputs of signal S15 and S16 are switched and delivered and the output of the 8th holding circuit is extracted by a signal S20. Thus the tracking error is some affected by the scratch but this effect can be satisfactorily reduced. While gate switches 32 and 31 are opened and closed by signals S15 and S16 for the tracking error signal. A gate switch 40 is added to open and close the outputs of both switches 32 and 31 via the 11th holding circuit 37 and the signal S20. As a result, an average focusing error signal is obtained and can be reduced satisfactorily when the effects of scratches are produced.

Abstract: PURPOSE:To increase the response speed at a low luminance and to decrease the influence of a camera shake by adjusting the level of a circuit for generating a luminance modulating level to maintain the specified integrating time and output from a photodetector array when the output from a clocking circuit exceeds the range of a normal time. CONSTITUTION:When brightness decreases, the integrating time increases gradually within an optional preset luminance modulating level and if the integrating time takes a specified value or above, the output from a reference time generating circuit 800 goes to a controller 1100 then the luminance modulating level is brought down by one step by the control of said controller 1100 and the integrating time is made shorter with respect to the same brightness. When the brightness increases, the integrating time decreases successively within the optional luminance modulating level and the output from the circuit 1000 goes to the controller 1100 then the luminance modulating level is brought up by one step by the control of the controller 1100 so that the integrating time is made longer with respect to the same brightness. The always specified integrated output voltage is thus obtd.
