Abstract
An image capturing apparatus includes a spatial light modulator configured to shape a wavefront of light traveling from a light source to an object, an image capturer configured to generate image data by capturing an image of the object, and a controller configured to control the spatial light modulator and to make the image capturer capture the image when object light among the light reaches the image capturer via the object. The controller performs an optimization control of the spatial light modulator so as to maximum or minimize a value of an objective function set by using a luminance value in a target area corresponding to the object light in the image data.

An image capturing apparatus comprising:
- a spatial light modulator configured to shape a wavefront of light traveling from a light source to an object;
- an image capturer configured to generate image data by capturing an image of the object;
- and
- a controller configured to control the spatial light modulator and to control the image capturer to capture the image of the object when object light via the object among the light reaches the image capturer,
- wherein the controller sets a target area corresponding to the object in the image data by performing image processing for the image data and performs an optimization control of the spatial light modulator so as to maximize or minimize a value of an objective function set based on image data of the target area in the image data.
An image capturing method comprising the steps of:
- shaping through a spatial light modulator a wavefront of light traveling from a light source to an object;
- generating through an image capturer image data by capturing an image of the object;
- and
- controlling the spatial light modulator and controlling the image capturer to capture the image of the object when object light via the object among the light reaches the image capturer,
- wherein the controlling includes setting a target area corresponding to the object in the image data by performing image processing for the image data and performing an optimization control of the spatial light modulator so as to maximize or minimize a value of an objective function set based on image data of the target area in the image data.
A non-transitory computer-readable storage medium storing a program that enables a computer to execute an image capturing method comprising the steps of:
- shaping through a spatial light modulator a wavefront of light traveling from a light source to an object;
- generating through an image capturer image data by capturing an image of the object;
- and
- controlling the spatial light modulator and controlling the image capturer to capture the image of the object when object light via the object among the light reaches the image capturer,
- wherein the controlling includes setting a target area corresponding to the object in the image data by performing image processing for the image data and performing an optimization control of the spatial light modulator so as to maximize or minimize a value of an objective function set based on image data of the target area in the image data.
