ABSTRACT:
An image pickup device has an image sensor which converts an optical image into electric information, and readout transfer paths to divide the information of one horizontal line of the sensor and to read it out, e.g., as dot signals. A control device distributes the above-mentioned information of one line with a predetermined period for each transfer path. An adjustment device adjusts the levels of the outputs from each of the readout transfer paths. The outputs of each of the color signals so adjusted are sequentially switched over and are sequence-processed. A suppression circuit provided in association with the sequencing circuitry suppresses the levels of each of the adjusted color signals to make those signals non-linear. Color filters may be provided, to produce color signals, and a luminance signal may be formed from the color signals. Delay circuits may be provided to ensure desired phase relations among the read-out signals.
