Imaging apparatus, exposure controlling method, and imaging device

An exposure controlling method, comprising:

• receiving, via plurality of directive pixels, incident light from an imaging target, wherein
• the incident light enters the plurality of directive pixels without intervention of any of an imaging lens and a pinhole,
• each directive pixel of the plurality of directive pixels has an incident angle directivity,
• the incident angle directivity for each directive pixel of the plurality of directive pixels is independently set with respect to an incident angle of the incident light, and
• the incident angle directivity indicates a value of a detection signal modulated based on the incident angle of the incident light at the plurality of directive pixels, and
• the detection signal is obtained from the plurality of directive pixels;
• receiving a non-directive detection signal outputted from a non-directive pixel, wherein
• the non-directive pixel receives the incident light without the intervention of any of the imaging lens and the pinhole, and
• the non-directive pixel does not have a configuration that provides an incident angle directivity;
• and
• controlling, via a circuitry, exposure of the plurality of directive pixels based on the non-directive detection signal.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:

• receiving, via a plurality of directive pixels, incident light from an imaging target, wherein
• the incident light enters the plurality of directive pixels without intervention of any of an imaging lens and a pinhole,
• each directive pixel of the plurality of directive pixels has an incident angle directivity,
• the incident angle directivity for each directive pixel of the plurality of directive pixels is independently set with respect to an incident angle of the incident light,
• the incident angle directivity indicates a value of a detection signal modulated based on the incident angle of the incident light at the plurality of directive pixels, and
• the detection signal is obtained from the plurality of directive pixels;
• receiving a non-directive detection signal outputted from a non-directive pixel, wherein
• the non-directive pixel receives the incident light without the intervention of any of the imaging lens and the pinhole, and
• the non-directive pixel does not have a configuration that provides an incident angle directivity;
• and
• controlling, via a circuitry, exposure of the plurality of directive pixels based on the non-directive detection signal.

An imaging device, comprising:

• a plurality of directive pixels, wherein
• each directive pixel of the plurality of directive pixels is configured to receive incident light from an imaging target,
• the incident light enters the plurality of directive pixels without intervention of any of an imaging lens and a pinhole,
• each directive pixel of the plurality of directive pixels has an incident angle directivity,
• the incident angle directivity for each directive pixel of the plurality of directive pixels is independently set with respect to an incident angle of the incident light,
• the incident angle directivity indicates a value of a detection signal modulated based on the incident angle of the incident light at the plurality of directive pixels, and
• the detection signal is obtained from the plurality of directive pixels;
• and
• a non-directive pixel configured to receive the incident light which enters the non-directive pixel without the intervention of any of the imaging lens and the pinhole, wherein
• the non-directive pixel does not have a configuration that provides an incident angle directivity,
• the non-directive pixel has a light reception sensitivity higher than the light reception sensitivity of each directive pixel of the plurality of directive pixels, and
• the non-directive pixel is used for exposure control of the plurality of directive pixels.
