Abstract
An aspect of the present invention provides an imaging apparatus comprising: a solid-state image sensor having an effective pixel area and an optical black area; a smear detection device which detects smear intensity and smear occurrence position in a smear occurrence area, in which a smear occurs, in the effective pixel area, based on an output signal obtained from the optical black area of the solid-state image sensor; and a smear correction device which performs smear correction by subtracting a smear correction value corresponding to the smear intensity from an output signal of the smear occurrence area and the vicinity thereof in the effective pixel area.
Claims15
An imaging apparatus comprising:
- a solid-state image sensor having an effective pixel area and an optical black area;
- a smear detection device which detects smear intensity and smear occurrence position in a smear occurrence area, which is an area where a smear occurs in the effective pixel area, based on an output signal obtained from the optical black area of the solid-state image sensor;
- and
- a smear correction device which performs smear correction by subtracting a smear correction value corresponding to the smear intensity from an output signal of the smear occurrence position and the vicinity thereof in the effective pixel area.
An imaging apparatus comprising:

- a smear detection device which detects smear intensity and smear occurrence position in a smear occurrence area, which is an area where a smear occurs in the effective pixel area, based on an output signal obtained from the optical black area of the solid-state image sensor;
- a smear occurrence proportion calculation device which calculates a smear occurrence proportion which is the proportion of the area of the smear occurrence area to the entire effective pixel area;
- and
- a black level correction device which performs black level correction by calculating a black level correction value based on the smear occurrence proportion and subtracting the black level correction value from all output signals of the effective pixel area.
