Abstract

An image sensor includes: a first imaging region that captures an image of light entering through an optical system under a first imaging condition and generates a detection signal to perform focus detection of the optical system; and a second imaging region that captures an image of the light entering through the optical system under a second imaging condition other than the first imaging condition and generates an image signal.

First claim

1 . An image sensor comprising:
a first imaging region that captures an image of light entering through an optical system under a first imaging condition and generates a detection signal to perform focus detection of the optical system; and a second imaging region that captures an image of the light entering through the optical system under a second imaging condition other than the first imaging condition and generates an image signal.

2 . An image sensor comprising:
a first imaging region that captures an image of light entering through an optical system under a first imaging condition and generates a detection signal to perform focus detection of the optical system; and a second imaging region that captures an image of the light entering through the optical system under a second imaging condition other than the first imaging condition and generates a signal for use in exposure calculation.

3 . An image sensor comprising:
a first imaging region that captures an image of light entering through an optical system under a first imaging condition and generates a detection signal to perform focus detection of the optical system; and a second imaging region that captures an image of the light entering through the optical system under a second imaging condition other than the first imaging condition and generates a signal for use in white balance adjustment.

4 . The image sensor according to claim 1 , wherein
the frame rate set under the first imaging condition is higher than the frame rate set under the second imaging condition.

5 . The image sensor according to claim 1 , wherein
the send imaging region has an area that is larger than an area of the first imaging region.

6 . An electronic apparatus comprising:
the image sensor according to claim 1 ; and a setting unit that sets a position at which the first imaging region is arranged and a position at which the second imaging region is arranged.

7 . The electronic apparatus according to claim 6 , further comprising:
an analysis unit that analyzes distribution of brightness of a subject, wherein the setting unit sets the position at which the first imaging region is arranged and the position at which the second imaging region is arranged based on the distribution of brightness analyzed by the analysis unit.

8 . The electronic apparatus according to claim 7 , wherein
the setting unit sets the first imaging region and the second imaging region in a region that is determined to contain a main subject based on a result of analysis by the analysis unit.

9 . The electronic apparatus according to claim 8 , wherein
the setting unit sets the second imaging region in a region other than the region that is determined to contain a main subject based on the result of analysis by the analysis unit.

10 . The electronic apparatus according to claim 6 , wherein
the setting unit sets the first imaging region and the second imaging region in a region that is determined to have brightness exceeding a predetermined brightness value based on the result of the analysis by the analysis unit.

11 . The electronic apparatus according to claim 6 , further comprising:
a storage unit that stores an image signal; and an instruction unit that instructs the storage unit to store an image signal, wherein the setting unit, if instructed by the instruction unit to store the image signal, cancels setting of the first image condition and setting of the second image condition.
