    摘要： A solid-state imaging device 5 includes photoelectric conversion elements 51R, 51G, 51B; and photoelectric conversion elements 51r, 51g, 51b. An exposure period for the photoelectric conversion elements 51r, 51g, 51b is controlled shorter than that for the photoelectric conversion elements 51R, 51G, 51B. During the exposure period for the photoelectric conversion elements 51R, 51G, 51B, an imaging device driving section 10 applies a readout pulse to transfer electrodes V2, V6, reads out electric charges accumulated in the photoelectric conversion elements 51r, 51g, 51b into vertical electric charge transfer paths 54, and controls to start exposure of the photoelectric conversion element 51r, 51g, 51b. During a period from start of the exposure of the photoelectric conversion elements 51R, 51G, 51B to the applying of the readout pulse, the imaging device driving section 10 applies a transfer pulse of a low level to the transfer electrodes V1 to V8.

    摘要： An image pickup apparatus has an image pickup device including an imaging section, in which signal charges read out from plural photosensitive cells are vertically transferred over vertical transfer paths and the transferred signal charges are in turn horizontally transferred over a horizontal transfer path, which has a branching section for assigning the transferred signal charges to plural output channels, i.e. plural horizontal transfer paths provided at the end of the horizontal transfer path. A temperature sensor for detecting the temperature of the image pickup device is provided on the imaging section, and a temperature-induced drift compensator corrects a transfer error of signal charges in the image pickup device. The compensator modifies transfer error correction based on the detected temperature. The image pickup apparatus can thus substantially reduce an assignment error even when the temperature of the image pickup device changes.

    摘要： In a signal reading method for a solid-state image pickup apparatus, an estimated photometric value is calculated at the time of preliminary image pickup and compared with a threshold value set beforehand. If the estimated photometric value is smaller than the threshold value, it is then determined that a scene to be pickup up has a narrower dynamic range to execute control reading out signal charges from the main and subregions of the individual photosensitive cell while mixing them together. If the estimated photometric value is not smaller than the threshold value, the signal charges of the main and subregions are read out independently of each other.

    摘要： In an image pickup apparatus for preventing linearity defect at the time of photographing in a high-sensitivity mode, when processing an image signal produced by a solid-state image pickup device under a predetermined condition, such as photographing in a super high-sensitivity mode, at a high temperature or with a long-time exposure, a signal processor increases a clamp level for clamping the image signal. A noise reducer then executes noise reduction for removing noise of random nature from the image signal before correcting the primary black level for the image signal, and thereafter the black level is corrected.

    摘要： An image combined high sensitivity image and low sensitivity image is provided with well-adjusted white balance and broad dynamic range. The image is obtained by multiplying the combined data by total gain that depends on scene. A white balance is adjusted with gain value calculated from of high output image data. Lv value representing luminance is calculated and compared with a threshold to decide whether or not the high sensitivity image and the low sensitivity image should be combined. First gamma correction unit performs gamma-correction for the image signal derived from the high sensitivity signal with first gamma character, second gamma correction unit performs gamma-correction for the image signal derived from the low sensitivity signal with second gamma character that is different from the first gamma character, and addition unit combines the image signal from the first gamma correction unit and the image signal from the second gamma correction unit.
