Abstract: An exposure time may become extremely long due to automatic exposure control. A control apparatus includes a circuit, configured to set an upper limit of an exposure time is provided. The circuit is configured to determine an exposure time of a photographing apparatus within a range below the upper limit according to an exposure control value of the photographing apparatus. A control method includes steps of setting an upper limit of an exposure time is also provided. The control method includes the following step: determining an exposure time of a photographing apparatus within a range below the upper limit according to an exposure control value of the photographing apparatus.

Abstract: An image processing device includes a processor and a storage device. The storage device stores a program that, when executed by the processor, causes the processor to select a first image signal in a first period, select the first image signal and a second image signal in a second period, generate image data for display based on the first image signal selected in the first period, and generate image data for recordation according to a predetermined recording format based on the first image signal and the second image signal selected in the second period. The first image signal has a first wavelength band and is output by a first image sensor of a camera device. The second image signal has a second wavelength band and is output by a second image sensor of the camera device.

Abstract: A correction circuit includes a memory that stores a mobility correction value or a threshold voltage correction value for correcting luminance non-uniformity for every pixel, a memory read-out unit that reads out the mobility correction value or the threshold voltage correction value from the memory, a correlation table that produces a threshold voltage correction value or a mobility correction value from the other one of the mobility correction value and the threshold voltage correction value on the basis of a correlation between mobility and a threshold voltage, a mobility correction unit correcting an input signal for every pixel by using the mobility correction value supplied from the memory read-out unit or the correlation table, and a threshold voltage correction unit correcting the input signal that is corrected at the mobility correction unit, by using the threshold voltage correction value supplied from the memory read-out unit or the correlation table.
