Abstract
An image pickup apparatus and an image pickup method perform different processing on signals from respective photoelectric conversion portions in accordance with changes of photographing conditions. The signals to be subjected to the different processing are output from an image pickup region provided with an arrangement of a plurality of arranged pixels each including a plurality of photoelectric conversion portions arranged in a depth direction severally.
Claims12
An image pickup apparatus comprising:
- an image pickup region provided with an arrangement of a plurality of arranged pixels each including a plurality of photoelectric conversion portions arranged in a depth direction;
- and
- operation unit which executes different operation processing on respective signals from said plurality of photoelectric conversion portions arranged in the depth direction, in accordance with a change of an image pickup condition.
An image pickup apparatus comprising:
- an image pickup region provided with an arrangement of a plurality of arranged pixels each including a plurality of photoelectric conversion portions arranged in a depth direction;
- control unit for controlling a calibration mode for performing photographing to obtain correction data and a main photographing mode for performing main image photographing;
- and
- correction unit for correcting a signal level ratio of signals obtained in said main photographing mode from said plurality of photoelectric conversion portions arranged in the depth direction, on a basis of the correction data obtained in said calibration mode.
An image pickup method using an image pickup region provided with an arrangement of a plurality of arranged pixels each including a plurality of photoelectric conversion portions arranged in a depth direction severally, said method comprising the steps of:
- performing image pickup using said image pickup region;
- and
- executing different operation processing on respective signals from said plurality of photoelectric conversion portions arranged in the depth direction, in accordance with a change of an image pickup condition.
An image pickup method using an image pickup region provided with an arrangement of a plurality of arranged pixels each including a plurality of photoelectric conversion portions arranged in a depth direction, said method comprising the steps of:
- performing calibration photographing using said image pickup region to obtain correction data;
- photographing a main image by use of said image pickup region;
- and
- correcting a signal level ratio of signals obtained in the step of photographing the main image from said plurality of photoelectric conversion portions arranged in the depth direction, on a basis of said correction data obtained in the step of performing calibration photographing.
