摘要： A response with a wider dynamic range is obtained without a need for irradiating strong radiation onto a subject (human body). A CCD controller 22 allows reading of imaging signals from CCD image sensors 1 to 12, which is performed twice during different time periods, once during a long exposure time period and once during a short exposure time period, with respect to the irradiation of a constant dose of radiation by an X-ray generator 25; and a main controller 26 allows a memory 24 to synthesize image data from the successively twice-read imaging signals into an image with proper timing. As a result, it becomes unnecessary to irradiate strong radiation onto a subject, such as a human body and other substances, as is done conventionally, owing to a radiation dose weak enough not to cause a harmful influence.

摘要： A solid-state image pickup device has a photoelectric conversion part performing photoelectric conversion on incident light, a comparison part connected to an output terminal of the photoelectric conversion part to compare an output voltage of the photoelectric conversion part with a reference voltage, a capacitive element having one end connected to the output terminal of the photoelectric conversion part, and a control line connected to the other end of the capacitive element. In a signal storage period, a first control voltage is applied to the control line so as to make an electric potential at the output terminal of the photoelectric conversion part fall outside a transition region of the comparator. In a signal read period, a second control voltage is applied to the control line so as to make the electric potential at the output terminal of the photoelectric conversion part fall within the transition region of the comparator.

摘要： A fixed-pattern noise elimination apparatus 4 eliminates a fixed-pattern noise component resulting from dark current out of an image signal outputted from an effective pixel of a solid-state image sensor 2 during image sensing, by using: a first dark current that is calculated based on a previously acquired signal outputted from a light-shielded pixel of the solid-state image sensor 2 and that is stored in a compensation data memory 6; a second dark current that is calculated based on a previously acquired signal outputted from the effective pixel of the solid-state image sensor 2 with no incident light and that is stored in the compensation data memory 6; and a third dark current that is calculated based on a signal outputted from the light-shielded pixel of the solid-state image sensor 2 during image sensing. With this configuration, a fixed-pattern noise component resulting from dark current can be effectively eliminated irrespective of the temperature of the solid-state image sensor.

摘要： In a voltage comparator of the present invention, across a gate and a source of an amplifier transistor, a phase compensating capacitor and a first switch circuit are connected with each other in series, and a second switch circuit for short-circuiting the phase compensating capacitor is provided. The second switch circuit is turned on when the first switch circuit is turned off so as to (1) short-circuit the phase compensating capacitor and (2) discharge the phase compensating capacitor which has been charged while the first switch circuit was turned on. This permits to completely turn off the first switch circuit, and to prevent distortion of an output signal outputted from an output terminal, thereby preventing accumulation of unnecessary charges in the phase compensating capacitor.

摘要： A brightness level converting apparatus improves a contrast of an image represented by an image pickup signal output from a logarithmic conversion solid-state image pickup device, so as to obtain a natural image. For this purpose, the brightness level converting apparatus converts brightness levels in the image pickup signal output from the solid-state image pickup device which logarithmically converts an incident light quantity. In the brightness level converting apparatus, a brightness level converting section converts the brightness levels in the image pickup signal by using a brightness level converting function expressed by an S-shaped curve which indicates the relation between an input brightness level and an output brightness level and includes one inflexion point. Therefore, the contrast in a low brightness level range in the image pickup signal is reduced. At the same time, the contrast in a high brightness level range is reduced while appropriately keeping a gradation. With this, the contrast in an intermediate brightness level range in the image pickup signal is improved considerably. Therefore, the image represented by the image pickup signal whose brightness levels are converted becomes a further natural image.
