摘要： A color filter (F) has a plurality of successively arranged recurrent groups of different color stripes. An image pickup tube (2) has a photoelectrical conversion target exposed to lights which passed through the color filter and an index signal generation pattern. The image pickup tube outputs a signal containing a color signal component determined by a carrier which is modulated with the individual color stripes of each recurrent group of the color filter (F). The output signal from the image pickup tube (2) also contains an index signal component which depends on the index pattern. A first memory (63) holds at least part of the index signal component. The index signal component held by the memory is periodically updated. A second memory (65) holds a portion of the output signal from the image pickup tube which was obtained under conditions where a predetermined color light illuminates the photoelectrical conversion target via the color filter (F). A reference signal is generated in accordance with the index signal component read from the first memory and with the signal portion read from the second memory. A color signal is detected from the output signal of the image pickup tube by use of the reference signal.

摘要： A color separation stripe filter (F) is used in a color image pickup apparatus so as to generate a color multiplexed signal (sm). The filter comprises a plurality of recurrent groups of three different color stripes (Cy,G,R) successively arranged at periodic intervals (T). The first color stripe has a characteristic showing a peak transmission factor (a) in a red color region, the second color stripe has a characteristic showing a peak transmission factor (b) in a green color region which is substantially equal to the peak transmission factor (a) of the first color stripe, and the third color stripe has a characteristic showing a negative peak transmission factor (c) at a wavelength between 500 nm and 530 nm so as to produce first and second peak transmission factors in a blue region (d) and said green region (e). The first peak transmission factor (d) is substantially equal to the peak transmission factors of the first (a) and second (b) color stripes, and the second peak transmission factor (e) existing in the green color region is 50% to 80% of the peak transmission factors of the first (a) and second (b) color stripes; the curve of the characteristic of the third color stripe in the green region being substantially similar in configuration to that of the second color stripe (b).

摘要： An electron beam focus in an image pickup tube (3φ) is varied in response to a focusing signal (Ef). An index signal generation pattern (42-45) is disposed in a light path (fig. 2-4) to a photoelectrical conversion target (4φ) of the image pickup tube (3φ). A level of the focusing signal is increased during at least part of an index pattern scanning period where the electron beam scans a portion of the photoelectrical conversion target which corresponds to the index signal generation pattern. A level of the focusing signal (Ef) is decreased during at least part of the index pattern scanning period. A level of an output signal from the image pickup tube (3φ) is detected (52, 1φ2 when the level of the focusing signal is increased (55, 56) (1φ5b, 1φ6). A level of the output signal from the image pickup tube is detected (52, 1φ2) when the level of the focusing signal is decreased (53, 58) (1φ5c, 1φ8). The detected levels are compared (61) (1φ7). During a period except the index pattern scanning period, the focusing signal is controlled (51) (11φ) in accordance with a result of the comparison between the detected levels.
