1. An image capture apparatus comprising: an image sensor which photo-electrically converts an object image formed by an imaging lens, the image sensor including a first pixel group having a first light-receiving area, and a second pixel group which is configured by dividing a light-receiving area into a second light-receiving area and a third light-receiving area different in area from the second light-receiving area; anda control unit configured to control the second and third light-receiving areas of the second pixel group and the first light-receiving area of the first pixel group of a same line by a same timing in an image capturing operation and configured to control the third light receiving areas of the second pixel group of different lines by a same timing in a detection operation of a focus state of the imaging lens. 2. The apparatus according to claim 1, wherein the image sensor includes a color filter with a Bayer arrangement, and the second pixel group is arranged at positions of two green pixels forming the Bayer arrangement. 3. The apparatus according to claim 2, wherein the control unit controls the third light-receiving area of one pixel in the second pixel group and the third light-receiving area of another pixel in the second pixel group that is arranged adjacent to the one pixel by the same timing. 4. The apparatus according to claim 1, further comprising a focus detection unit configured to detect the focus state of the imaging lens based on an output signal from the third light-receiving area of the second pixel group of the image sensor. 5. The apparatus according to claim 1, wherein the second pixel group is discretely disposed within the first pixel group. 6. The apparatus according to claim 1, wherein the second pixel group is configured by dividing the light-receiving area substantially equal in area to the first light-receiving area into the second light-receiving area and the third light-receiving area.
