    摘要: An image pickup apparatus comprising: a plurality of pixels each with a photodiode, a logarithmic converter including a logarithmic-converting MOS transistor for converting an output of the photodiode into an electric signal proportional to a logarithmic value of an amount of incident light on the photodiode, and an integration circuit for accumulating an output from the logarithmic converter; a voltage controller for control of a voltage to be applied to the transistor; and an output circuit for receiving signals from the pixels and outputting processed signals. The voltage controller realizes a moving object extraction image pickup state in which an image pickup signal is generated for displaying at least a part of the moving object existing in an image picked-up region at a density different from that of a static background part.

    摘要: An image signal, a noise signal, and an overflow signal outputted from a solid-state image-sensing device are sampled-and-held in capacitors C1, C2, and C3 in a sample-and-hold circuit 17. Thereafter, the image signal and the noise signal in the capacitors C1 and C2 are fed to a subtractor 50 in a correction circuit 18, so that the image signal having noise eliminated therefrom is fed to an operator 51. In this operator 51, according to the value of the overflow signal in the capacitor C3, the image signal having noise eliminated therefrom is corrected by adding thereto an integrated component.

    摘要: When the brightness of a subject detected by a detecting device 4 is higher than a predetermined value, for example 700 [cd/m2], a switching judgment circuit 5 judges that an area sensor (solid-state image-sensing device) 3 should perform logarithmic conversion. In response to this judgment by the switching judgment circuit 5, a switching signal generating circuit 6 outputs a switching signal to instruct the area sensor 3 to perform logarithmic conversion. When the brightness of the subject detected by the detecting device 4 is lower than the predetermined value, for example 700 [cd/m2], a switching judgment circuit 5 judges that the area sensor 3 should perform linear conversion. In response to this judgment by the switching judgment circuit 5, the switching signal generating circuit 6 outputs a switching signal to instruct the area sensor 3 to perform linear conversion.

    摘要: A level shifter (181) shifts a signal level of a noise signal produced from a pixel so that the signal level becomes close to a reference level, and then a level shifter (182) complements the noise signal whose level was shifted by the level shifter (181) by a signal level corresponding to the level shifted by the level shifter (181). After that, the differential amplifier (183) performs subtraction operation between the noise signal that has passed the level shifters (181, 182) and the image signal from the pixel, so as to output the image signal without noises.

Then, a switch SW3 is turned on to reset the input side of the buffer 6. Next, switches SW1b and SW2b are turned on simultaneously so that the noise signal in the capacitor Cb is fed through the buffer to a capacitor Cd, and then the switches SW1b and SW2b are turned off. Then, the switch SW3 is turned on to reset the input side of the buffer 6 again.
