by the examiner. A second amendment after final rejection was
filed on September 23, 1997 and was entered by the examiner.
The disclosed invention pertains to the field of image
sensing devices. More particularly, the invention converts a
photoelectric signal indicative of incident light into an
analog signal which is logarithmically proportional to the
photoelectric signal. The analog signal is further adjusted
before being converted to a digital signal. This technique is
described as improving white balance correction of image
signals.
Representative claim 1 is reproduced as follows:
1. An image sensing device comprising:
a photoelectric signal generator which is sensitive to an
incident light and which generates a photoelectric signal
proportional to an intensity of the incident light;
a converter which is connected with said photoelectric
signal generator to receive the photoelectric signal and to
generate a first analog signal which is logarithmically
proportional to the photoelectric signal;
a signal adjusting device which is connected with said
converter to receive the first analog signal and to adjust a
direct-current component of the first analog signal in order
to generate a second analog signal; and
