Apparatus methods and computer readable storage mediums for exposure control

摘要

An apparatus including: a processor configured to control a flash unit in an exposure time period of an image sensor array, to provide a first non-zero light intensity in a first portion of the exposure time period and to provide a second non-zero light intensity, different to the first light intensity, in a second portion of the exposure time period.

主权项

1. An apparatus comprising:
at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the at least one processor to control a flash unit in an exposure time period of an image sensor array, wherein the at least one processor is further configured to receive information indicative that there is a requirement for electrical energy other than by the at least one processor and flash unit and control the flash unit in the exposure time period of the image sensor array, using the received information, to provide a first non-zero light intensity in a first portion of the exposure time period and to provide a second non-zero light intensity in a second portion of the exposure time period, wherein the intensity of the first non-zero light intensity is different to the intensity of the second non-zero light intensity.
