Abstract
An imaging apparatus includes an imaging unit configured to acquire a first image and a second image which is generated by performing accumulation of signal charges a plurality of times in one image capturing period, and a control unit configured to control accumulation of signal charges which is performed by the imaging unit. The control unit determines a number of times of accumulation of signal charges for generating the second image according to an accumulation time of signal charges for generating the first image.
Claims19
An imaging apparatus comprising:
- an imaging unit configured to acquire both a first image and a second image in one image capturing period, wherein the second image is acquired by performing multiple accumulations of signal charges in the one image capturing period, wherein the multiple accumulations do not overlap each other in the one image capturing period, and wherein the first image is acquired by performing an accumulation of signal charges for an accumulation period in the one image capturing period;
- and
- a control unit configured to control accumulation of signal charges by the imaging unit,
- wherein the control unit determines a number of the multiple accumulations of signal charges, in the one image capturing period, for acquiring the second image based on the accumulation period, in the one image capturing period, of the accumulation of signal charges for acquiring the first image.
A control method for an imaging apparatus, the control method comprising:
- performing an imaging operation to generate both a first image and a second image in one image capturing period, wherein the second image is generated by performing multiple accumulations of signal charges in the one image capturing period, wherein the multiple accumulations do not overlap each other in the one image capturing period, and wherein the first image is generated by performing an accumulation of signal charges for an accumulation period in the one image capturing period;
- and
- performing a control operation to control accumulation of signal charges by the imaging operation,
- wherein the control operation determines a number of the multiple accumulations of signal charges, in the one image capturing period, for generating the second image based on the accumulation period, in the one image capturing period, of the accumulation of signal charges for generating the first image.
An imaging apparatus comprising:
- an imaging unit configured to generate both a first image and a second image in one image capturing period, wherein the first image is generated by performing an accumulation of signal charges for an accumulation period in the one image capturing period, wherein the second image is generated by performing a plurality of discrete accumulations of signal charges in the one image capturing period, and wherein the plurality of discrete accumulations each have a respective accumulation period in the one image capturing period;
- and
- a control unit configured to control accumulations of signal charges by the imaging unit, wherein the control unit determines a number of the plurality of discrete accumulations of signal charges, in the one image capturing period, for generating the second image based on the accumulation period, in the one image capturing period, of the accumulation of signal charges for generating the first image.
