Imaging device and method

An imaging device comprising:

• a modulator configured to modulate an intensity of incident light in accordance with a real pattern;
• an image sensor configured to convert the modulated light into an electric signal and create a sensor image;
• a micro lens array including a plurality of micro lenses arranged to correspond to a plurality of pixels of the image sensor;
• and
• a scattering member arranged on an entrance side of the micro lens array and configured to scatter the modulated light.

An imaging method in an imaging device,

• wherein the imaging device includes:
• a modulator configured to modulate an intensity of incident light in accordance with a real pattern;
• an image sensor configured to convert the modulated light into an electric signal and create a sensor image;
• and
• a micro lens array including a plurality of micro lenses arranged to correspond to a plurality of pixels of the image sensor,
• wherein the imaging device has a distribution property of a relative positional difference amount between a center position of a light receiver of each pixel of the plurality of pixels and a center position of each micro lens of the plurality of micro lenses of the micro lens array in a plane of the image sensor, and
• the property has at least one point or more with a changing difference value of the difference amount between the adjacent pixels from a positive value to a negative value or from a negative value to a positive value,
• the method comprising the steps of:
• modulating the intensity of the light by the modulator;
• and
• creating the sensor image by the image sensor in accordance with the modulated light having travelled in the modulator and the micro lens array.
