  • Patent number: 9066033
    Abstract: Among defective pixels of an image sensor, defective pixels which need to be corrected are determined depending on the type and defect level for individual defective pixels and on image capturing conditions. Depending on the types of the defective pixels, the correspondences between the image capturing conditions and the defect levels of the defective pixels to be corrected are prepared in advance, thereby carrying out appropriate defective pixel correction in view of the fact that the dependence of the abnormal signal output level on the image capturing conditions differs depending on the type of defective pixel.

  • Patent number: 8810695
    Abstract: An apparatus includes an image sensor, a detection unit, and a control unit. The image sensor photoelectrically converts an incident light from an object. The detection unit detects a defective pixel of the image sensor based on an image signal generated by the image sensor. The control unit controls, when a first defective pixel for irregularly outputting an abnormal level and a second defective pixel for regularly outputting an abnormal level in the image sensor are detected, storage time of the image sensor at the detection time of the first defective pixel to be longer than storage time of the image sensor at detection time of the second defective pixel and a number of image signals used for detection to be larger.

  • Patent number: 8576316
    Abstract: An image sensing apparatus capable of reducing degradation of a signal-to-noise ratio property occurring when a driving frequency of an image sensing element is high, depending on a state of an operation mode. An information table is stored in a memory section, which includes information on a timing of a horizontal transfer driving signal for performing charge transfer in the horizontal direction in an image sensing element, information on a timing of a reset gate signal for performing charge sweep per pixel, and information on a timing of a feed-through sample-hold signal for sample-holding a feed-through section of the output signal of the image sensing element which becomes a black reference per pixel, in association with an operation mode of an image sensing apparatus. The information table associated with the set operation mode is selected from the memory section, and the element is driven based on the information table.
