| 1. A solid-state imaging device, comprising:
an image sensor configured to output image data generated by image sensing elements together with a timing signal; and
an image processing unit configured to start performing, in response to the timing signal indicating a first timing, predetermined
signal processing on the image data supplied from said image sensor a predetermined delay time after the first timing indicated
by the timing signal,
wherein the timing signal supplied from the image sensor to the image processing unit is separate from the image data supplied
from the image sensor to the image processing unit, and indicates the first timing that is at least the predetermined delay
time earlier than a second timing indicative of a start of a valid period of the image data to trigger the predetermined signal
processing at the first timing, and
wherein the image data output from the image sensor to be input into the image processing unit includes dummy data preceding
the image data of the valid period from the first timing to the second timing.
