摘要： An image pickup apparatus which can remove flickers appearing in a frame of a solid-state image pickup device is disclosed. A light amount detector (2) is provided in the proximity of a sensor light receiving section (1), and the amount of light incoming to the sensor light receiving section (1) is normally monitored by the light amount detector (2). Detection data of the light amount detector (2) is signaled to a light amount detection data processing section (correction value calculation section) (4). The light amount detection data processing section (4) detects a current light amount condition based on the detection data inputted thereto and calculates correction data for removal of flickers based on the detected current light amount condition. A microcomputer performs an calculation process to obtain a maximum value and a minimum value of the light amount to detect the period of light emission of a light source. Then, an inverse number of an integration value of the light amount is multiplied by the image pickup signal such that the phase is displaced by 90° with respect to the light emission period of the light source to perform correction. The correction is performed by sending the correction data to a multiplier (gain amplifier) section (7).

摘要： A waveguide-type optical matrix switch including as its switching element a Mach-Zehnder interferometer which includes two directional couplers and an optical phase shifter. The two directional couplers are arranged by placing two optical waveguides in close proximity at two positions on a substrate, and have an identical coupling ratio. The optical phase shifter is disposed over at least one of the two optical waveguides between the directional couplers. The two optical waveguides have an effective optical path length difference of half a wavelength of a light signal between the two directional couplers, and are intersected in the optical switch element. The waveguide-type optical matrix switch is little affected by fabrication errors in the coupling ratio of the directional couplers, and superior in the extinction ratio.

摘要： A plurality of flicker detection frames are formed by dividing an image into a plurality of frames. A flicker detection circuit performs detection of luminance data for each of the flicker detection frames. The differences between the luminance data of the preceding frame and the current frame, and between the luminance data of the current frame and the following frame with respect to each of the flicker detection frames are taken, a flicker component is extracted, and the flicker frequency is calculated, by a flicker frequency determination program in a microcomputer. Then, the space between the flicker detection frames in which a crest or trough of the extracted flicker component appears is measured, and the results are converted into the flicker frequency. The frame rate of the image pickup signals is controlled so as not to be synchronized with the flicker frequency.
