Abstract:
An image pick-up apparatus on which a chip-like image pick-up device for receiving subject light passing through a picture-taking lens and taking an image electronically is mounted, comprising:a first light receiving element group which is formed on the chip-like image pick-up device and comprises a plurality of first light receiving elements arranged to allow the subject light which passes through the picture-taking lens to be received; a first microlens group which is placed on the chip-like image pick-up device and comprises a plurality of microlenses arranged to respectively oppose the first light receiving elements of the first light receiving element group, for allowing the subject light which has passed through the picture-taking lens to converge on the first light receiving elements; a second light receiving element group which is formed on the chip-like image pick-up device and comprises a plurality of second light receiving elements each comprising a pair of light receiving portions which receive the subject light which passes through the picture-taking lens; a second microlens group which is placed on the chip-like image pick-up device and comprises a plurality of microlenses arranged to respectively oppose the second light receiving elements of the second light receiving element group for allowing the subject light which has passed through the picture-taking lens to be pupil-divided into light beams; focus detection means for effecting focus detection based on outputs of the second light receiving element group; correction means for correcting output signals corresponding to a subject image and to a focus detection area present at the second light receiving element group on the basis of outputs of the first light receiving element group; and image pick-up means for picking up the subject image based on signals obtained by correcting signals output from the first light receiving element group and signals output from the second light receiving element group by the correction means.
