Abstract

An imaging unit of an embodiment of the present technology includes: a detector that detects temperature or remaining battery capacity; an imaging device that obtains a captured image; and a first correction section that changes, on a basis of a detection result of the detector, electronic hand shake correction accuracy with respect to the captured image obtained by the imaging device when an electronic hand shake correction function is enabled.

First claim

What is claimed is:

1. An imaging unit, comprising:
a detector that detects temperature or remaining battery capacity;
an imaging device that obtains a captured image; and
a first correction section that changes, on a basis of a detection result of the detector, electronic hand shake correction accuracy with respect to the captured image obtained by the imaging device when an electronic hand shake correction function is enabled, wherein in response to a first detection result of the detector a first hand shake correction accuracy is enabled, wherein in response to a second detection result of the detector a second hand shake correction accuracy is enabled, and wherein the first hand shake correction accuracy is higher than the second hand shake correction accuracy.

2. The imaging unit according to claim 1 , wherein the first correction section changes, on the basis of the detection result of the detector, a size of a hand shake correction margin when a region including an object is cut out from the captured image.

3. The imaging unit according to claim 2 , wherein the first correction section changes the number of pixels of the captured image on the basis of the detection result of the detector.

4. The imaging unit according to claim 3 , wherein
the first correction section includes an analog-to-digital converter that converts the captured image into digital data, and
the analog-to-digital converter changes a size of an analog-to-digital conversion region in the captured image, on the basis of the detection result of the detector.

5. The imaging unit according to claim 1 , wherein
the first correction section includes a first analog-to-digital converter that converts the captured image into digital data,
the imaging device includes a second analog-to-digital converter that converts the captured image into digital data,
each of the first analog-to-digital converter and the second analog-to-digital converter changes a size of an analog-to-digital conversion region in the captured image, on the basis of the detection result of the detector, and
the first correction section determines whether to use the first analog-to-digital converter or the second analog-to-digital converter, on the basis of the detection result of the detector.

6. The imaging unit according to claim 1 , wherein
the imaging device includes a second correction section that changes, on the basis of the detection result of the detector, the electronic hand shake correction accuracy with respect to the captured image obtained by the imaging device when the electronic hand shake correction function is enabled, and
the first correction section determines whether to use the first correction section or the second correction section, on the basis of the detection result of the detector.

7. The imaging unit according to claim 1 , wherein the first correction section sets a threshold for change of the electronic hand shake correction accuracy to be different between when temperature rises and when the temperature falls.

8. The imaging unit according to claim 1 , wherein the first correction section sets a threshold for change of the electronic hand shake correction accuracy to be different between when a power voltage rises and when the power voltage falls.

9. The imaging unit according to claim 1 , wherein the first correction section is provided in a logic circuit that is stacked on the imaging device.

10. The imaging unit according to claim 2 , wherein the first correction section turns off electronic hand shake correction when the hand shake correction margin becomes lower than a certain value.

11. The imaging unit according to claim 2 , wherein the first correction section changes correction from electronic hand shake correction to optical hand shake correction when the hand shake correction margin becomes lower than a certain value.

12. An electronic apparatus provided with an imaging unit, the imaging unit comprising:
a detector that detects temperature or remaining battery capacity;
an imaging device that obtains a captured image; and
a first correction section that changes, on a basis of a detection result of the detector, electronic hand shake correction accuracy with respect to the captured image obtained by the imaging device when an electronic hand shake correction function is enabled, wherein in response to a first detection result of the detector a first hand shake correction accuracy is enabled, wherein in response to a second detection result of the detector a second hand shake correction accuracy is enabled, and wherein the first hand shake correction accuracy is higher than the second hand shake correction accuracy.

13. The imaging unit according to claim 1 , wherein the detector detects temperature, wherein the first detection result is a first temperature, wherein the second detection result is a second temperature, and wherein the first temperature is lower than the second temperature.

14. The imaging unit according to claim 1 , wherein the detector detects remaining battery capacity, wherein the first detection result is a first remaining battery capacity, wherein the second detection result is a second remaining battery capacity, and wherein the first remaining battery capacity is higher than the second remaining battery capacity.

15. The imaging unit according to claim 1 , wherein the detector detects temperature.

16. The imaging unit according to claim 1 , wherein the detector detects remaining battery capacity.
