摘要： An image-taking apparatus which captures object light to take an image includes: an optical device through which the object light is transmitted; an image pickup device which generates an image signal representing an object image; and a cleaning section which is deformed by receiving a predetermined stimulus, the cleaning section being brought into contact with, and being separated from, the optical device and/or the image pickup device to clean substances attached to the contact portion. The apparatus further includes: a stimulus application section which applies the stimulus to the cleaning section; and a control section which controls the deformation of the cleaning section by controlling the stimulus applied from the stimulus application section, and which thus causes the cleaning section to clean the contact portion.

摘要： The image taking apparatus of the invention includes a light quantity control device that is arranged on the optical axis of subject light and controls transmitted volume of the subject light. The light quantity control device includes a light quantity control layer and a pair of light-transmissive electrodes. The light quantity control layer expands and contracts in accordance with an electric field generated therein and thereby changes the transmitted volume of the subject light. The electrodes are disposed so as to sandwich the light quantity control layer and generate an electric field in the light quantity control layer, in response to application of voltage, thereby causing the light quantity control layer to expand and contract.

摘要： An optical barrel includes an outer wall and space members. The outer wall has a plurality of tube members which are each in tube form and are engaged one another in such a manner that one tube is inserted inside another and are relatively moved by a driving force. The space members are mounted between the plurality of tube members which open and close the spaces between the plurality of tube members by expanding and contracting in response to application and release of a voltage.

摘要： An optical reproducing device according to the present invention detects mean amplitude values of short marks and long marks, which are recorded marks for reproducing power control, by means of a short mark level detecting circuit and a long mark level detecting circuit. Then a differential amplifier compares a ratio between these two mean amplitude values with a standard value, and outputs the result of this comparison. Thereafter, a reproducing power control circuit controls reproducing power of a semiconductor laser such that the absolute value of this comparison result is reduced. Since mean values of the amplitude values of the short marks and long marks are detected, the detection results are very accurate, and the precision of control of reproducing power can be greatly improved.
