Abstract
An apparatus and a method for acquiring an image in an electronic device are provided. The method includes acquiring a first image using an image sensor that comprises a plurality of first pixels having a first exposure and a plurality of second pixels having a second exposure, determining a reference exposure value based on image information, adjusting at least one of the first exposure or the second exposure based on the reference exposure value, and acquiring a second image using the image sensor based on exposure control.
Claims16
A method for acquiring an image in an electronic device, the method comprising:
- acquiring a first image using an image sensor that comprises a plurality of first pixels having a temporary first exposure and a plurality of second pixels having a temporary second exposure;
- detecting a reference exposure value based on information of the first image;
- adjusting at least one of the first exposure or the second exposure based on the reference exposure value;
- and
- acquiring a second image using the image sensor based on the adjusted at least one of the first exposure or the second exposure,
- wherein the information of the first image includes at least one of a weight corresponding to a location of the electronic device and a face detection auto exposure,
- wherein the adjusting of the at least one of the first exposure or the second exposure comprises:
- comparing a reference range corresponding to the reference exposure value with the first exposure and the second exposure;
- and
- adjusting at least one, outside the reference range, of the first exposure or the second exposure based on the compared result
- to be a maximum value of the reference range.
An electronic device comprising:
- an image sensor comprising an array of pixels configured to acquire image data from the array of the pixels;
- and
- at least one processor configured to process the image data,
- wherein the array of the pixels comprises a plurality of first pixels having a temporary first exposure and a plurality of second pixels having a temporary second exposure,
- wherein the processor is configured to:
- acquire a first image using the image sensor,
- detect a reference exposure value based on information of the first image,
- adjust at least one of the first exposure or the second exposure based on the reference exposure value, and
- acquire a second image using the image sensor based on the adjusted at least one of the first exposure or the second exposure,
- wherein the information of the first image includes at least one of a weight corresponding to a location of the electronic device and a face detection auto exposure, and
- wherein the at least one processor is further configured to:
- compare a reference range corresponding to the reference exposure value with the first exposure and the second exposure, and
- adjust at least one, outside the reference range, of the first exposure or the second exposure based on the compared result
- to be a maximum value of the reference range.
