摘要： An image capturing system includes a signal correction unit which corrects a signal output from a defective pixel in an optical black region based on a signal output from a normal pixel. The optical black region has a plurality of pixel blocks. Each of the plurality of pixel blocks has a plurality of pixels each including one or more elements which have the same functions as in the remaining pixels and which have relative positions different from the remaining pixels. The signal correction unit corrects the signal output from the defective pixel in the optical black region based on a signal output from a normal pixel which is included in another pixel block different from the pixel block of the defective pixel in the optical black region and includes one or more elements having the same functions and same relative positions as in the defective pixel.

摘要： In an imaging apparatus, a first conversion unit multiplexes input signals including control signals for driving an image sensor to generate a multiplex signal having a frequency higher than those of the input signals. A transfer unit transfers the multiplexed signal generated by the first conversion unit according to low-voltage differential signaling. A reception unit receives the multiplexed signal from the transfer unit. A second conversion unit extracts the control signals for driving the image sensor from the multiplexed signal received by the reception unit. A third conversion unit performs at least one of correction processing and development processing on a signal generated by the image sensor. A signal generation unit generates and supplies processing timing control signals to the first conversion unit and the third conversion unit.

摘要： When pixel data of a solid-state image-pickup device is read in various types of methods to pick up images, a correction process for defective pixels is easily performed at a low cost. As defect-correction data in a case in which a still image is shot, data is used, which is acquired when an image-pickup device is shipped from a manufacturing factory. In a case of an operation in a reading mode for a moving image, immediately before a reading operation is performed, charge is accumulated in a state in which the image-pickup device is shielded from light, and image data is read. Addresses of defective pixels to be corrected are detected from the image data, and stored in a RAM as the defect-correction data. When a moving image is shot, a defect-correction process is performed using the data.
