Light receiver, method and transmission system with time variable exposure configurations |
摘要 |
According to one embodiment, a light receiver includes a light reception module, a multi-exposure area selector, a multi-exposure controller, and a readout module. The light reception module includes N lines, each of the N lines having a plurality of light receiving elements. The multi-exposure area selector is configured to select one or a plurality of single-exposure lines and one or a plurality of multi-exposure lines. The multi-exposure controller is configured to, per the unit time, perform an exposure on the single-exposure lines one time for a first exposure time; and a first exposure and a second exposure on the multi-exposure lines. The readout module is configured to read exposure amounts of the lines line by line. The multi-exposure controller is configured to start the second exposure on the multi-exposure lines before reading of the exposure amounts of all the single-exposure lines is completed. |

1. A light receiver comprising:
a light reception module comprising N (N is an integer of 2 or more) lines, each of the N lines comprising a plurality of light receiving elements; a multi-exposure area selector configured to select one or a plurality of single-exposure lines to be exposed one time per a unit time and one or a plurality of multi-exposure lines to be exposed a plurality of times per the unit time among the N lines; a multi-exposure controller configured to, per the unit time, perform:
an exposure on the single-exposure lines one time for a first exposure time; anda first exposure on the multi-exposure lines for the first exposure time and then a second exposure on the multi-exposure lines for a second exposure time; and a readout module configured to read exposure amounts of the lines line by line, wherein the multi-exposure controller is configured to start the second exposure on the multi-exposure lines before reading of the exposure amounts of all the single-exposure lines is completed. |
