Abstract
An image sensor capable of switching between a first path configured to output an image signal read from a plurality of pixels to an external after storing the image signal in a memory, and a second path configured to output the image signal to the external without storing the image signal in the memory is configured. In a case of shooting using a supplemental light source, the image sensor is controlled so as to use the first path and to have a speed for reading the image signal from the plurality of pixels be faster than a speed for outputting the image signal from the memory to the external.
Claims12
An electronic device comprising:
- an image sensor having a plurality of pixels and capable of switching between a first path in which an image signal read from the plurality of pixels is stored in a memory and then outputted from the memory to an external, and a second path in which the image signal read from the plurality of pixels is output to the external without being stored in the memory;
- a processor that executes a program stored in a memory and functions as:
- a control unit configured to, in a case of performing shooting that uses a supplemental light source, control the image sensor so as to use the first path and to make a speed at which the image signal is read from the plurality of pixels faster than a speed at which the image signal is outputted from the memory to the external.
An image sensor comprising:
- a plurality of pixels;
- and
- switching circuitry that switches between a path in which an image signal read from the plurality of pixels is stored in a memory and then outputted from the memory to an external, and a path in which the image signal read from the plurality of pixels is output to the external without being stored in the memory.
A method of controlling an electronic device having an image sensor having a plurality of pixels and capable of switching between a first path in which an image signal read from the plurality of pixels is stored in a memory and then outputted from the memory to an external, and a second path in which the image signal read from the plurality of pixels is output to the external without being stored in the memory, the method comprising:
- in a case of performing shooting that uses a supplemental light source, controlling the image sensor so as to use the first path and to make a speed at which the image signal is read from the plurality of pixels faster than a speed at which the image signal is outputted from the memory to the external.
A non-transitory computer-readable medium storing a program for a computer included in an electronic device,
- wherein the electronic device comprises an image sensor having a plurality of pixels and capable of switching between a first path in which an image signal read from the plurality of pixels is stored in a memory and then outputted from the memory to an external, and a second path in which the image signal read from the plurality of pixels is output to the external without being stored in the memory, and
- wherein the program, when executed by the computer, causes the computer to function as a control unit configured to, in a case of performing shooting that uses a supplemental light source, control the image sensor so as to use the first path and to make a speed at which the image signal is read from the plurality of pixels faster than a speed at which the image signal is outputted from the memory to the external.
