BACKGROUND
[0002]
Display devices that reproduce images, such as
video images for vieWing typically include one or more
picture parameters or control variables that can be adjusted
to affect the quality of the displayed video image. Exemplary
display devices include computer monitors, studio video
monitors, and television sets. Some exemplary picture con
trol variables include brightness, saturation, color, and hue.
Picture quality depends at least in part upon ambient light
conditions as Well as user preferences. Video monitors, for
example, typically include controls for both brightness and

the end user is often left With a non-optimal setting of the
picture control variables.
[0006]
Resources are available to guide an end user
through a detailed setup procedure (see for example “FAQ:
HoW to Adjust a TV” available on the Internet at http://
myWeb.accessus.net/~090/hoW2adj .html). These procedures
provide a so-called “eyeball” calibration designed to obtain
a vieWable image approximating a standard, such as the
National Television Systems Committee (NTSC) standard.
As such, these procedures may not satisfy the taste of any
given end user, particularly as the picture controls interplay
With the colors and lighting of the surrounding environment.
Additionally, such calibration procedures may call for one or
more standard test patterns that must be obtained separately
(i.e., purchased) and used in combination With the proce

TV sets, for example, often provide users With
that produces uncertain and even con?icting results. For
example, the brightness and contrast labels ascribed to the
video monitor control variables can be misleading With
respect to their functions. Namely, the brightness control
variable primarily affects reproduced contrast (i.e., black
level); Whereas, the contrast control variable primarily
affects only brightness (i.e., White level). Setting the bright
ness control variable too high results in blacks being dis
played as grays. Proper adjustment of the brightness control
variable ensures that black video image content displays as
true black on the video monitor. Improper adjustment of this
control variable is a common problem resulting in poor
control variables.
[0008] In one aspect, the invention features a picture
adjustment process for optimiZing presentation of an image
bearing signal on a display device having at least one
adjustable picture control variable. The process includes
receiving an image-bearing signal, determining a ?rst group
of picture control settings, each representing a different
con?guration of the at least one adjustable picture control
variable, and generating an on-screen display image having
multiple pictures or image cells. Each of the image cells is

[0027] FIG. 1 shoWs a functional block diagram of an
exemplary video display device 100 in the form of a
television (TV) receiver, referred to herein as a TV set 100.
The TV set 100 includes a video receiving subsystem 105
[0033] The video receiving subsystem 105 includes an RF
receiver 130 coupled to the RF input port 12011. The RF
input port 12011 includes a radio-frequency (RF) coaxial
for receiving a video signal, and a display processing
subsystem 110 for processing image content of the received
video signal for display. Avideo display screen 115 provides
a visual representation or picture of the image content of the
cable source. The RF input port 12011 receives the entire TV
broadcast spectrum, or at least a portion thereof. The TV

providing respective audio-visual content. The audio-visual
content is impressed (i.e., modulated) upon a respective RF
carrier signal associated With each of the different channels.
[0034] The RF receiver 130 includes a tuner for selecting
a desired channel and a demodulator for extracting audio

signals can be received over one or more different media,
including terrestrial TV broadcasts, cable broadcasts, and
satellite broadcasts. Other input ports 120b, 1200 are
adapted to receive external audio/visual input signals from

doWn the composite video signal into its components for
times referred to as digital versatile disc), computers, and
game consoles.
[0029] Each of the input ports 120 includes a physical
interface that generally conforms to one of a number of
available standard video interfaces. Some exemplary video
interfaces include Digital Video Interface (DVI); High
De?nition Multi-media Interface (HDMI); component
video; “Separate” Video (referred to as S-Video); and
SCART (French-originated standard and associated 21-pin
connector for connecting audio and video equipment to
television sets).
[0030] DVI refers to a standard interface betWeen digital
devices such as projectors and personal computers. A DVI
interface is primarily a digital interface that may be all
digital, or a digital With an analog component. Accordingly,
a DVI-compliant interface accommodates high-bandWidth
The output of the RF receiver 130 includes a
further processing by the display processing subsystem 110.
For example, an NTSC decoder breaks doWn the NTSC
video formatted signal to obtain three component signals: a
black-and-White component signal and tWo color component
signals.
[0036]
It is Worth noting that the audio signal is typically
received together With the video signal from Which it can be
demultiplexed for separate processing. As the invention
relates to video processing, audio signal processing is not
described further herein.
[0037] In some embodiments the demodulated audio-vi

subsystem 110.
[0043] The controller 155 is also coupled to the display
processing subsystem 110 and optionally to the display
video signal. Exemplary external devices include cable
thereby tuning visual display of the video images. These
adjustable picture control variables include picture param
boxes and satellite receivers (referred to generally as “set
top boxes”). Although tWo codecs 140 are shoWn, in some
embodiments a single codec 140 can be shared among tWo
or more of the video input ports 120. The codecs 140 can be
implemented in softWare, hardWare, or a combination of
both softWare and hardWare.
[0039] The video receiving subsystem 105 also includes a
multiplexer (MUX) 145 used to select one of the input ports
120 for further processing and display. Depending upon a
control input received from the controller 155, the MUX 145
interconnects a video signal from the selected input port 120
to the display processing subsystem 110. The display pro
cessing subsystem 110, in turn, includes a display processor
150 that converts the received video signal to an image
output signal. The image output signal is ultimately for
Warded to the video display screen 115 for vieWing.
[0040] In more detail, the display processor 150 processes
video images by performing conversions to a signal format
appropriate for displaying video images on the display
screen 115. These conversions can include one or more of
color-space conversions (e.g., from RGB to YUV), format
conversions (e.g., from non-interlaced to interlaced frame
sequences), and pixel stream encoding to one of the standard
formats (e. g., NTSC, PAL and SECAM). For example, When
receiving an NTSC video signal, the display processor 150
extracts the black-and-White signal information and infor
screen 115 to adjust the one or more picture control variables
eters provided by the manufacturer. Most TV sets 100 and
video monitors provide some level of adjustment for picture
control variables that can be manipulated through the user
interface 160. For example, many standard picture control
variables include: brightness, contrast, color, tint, and sharp
ness. Adjusted values for each of the one or more picture
control variables, referred to herein collectively as a picture
control setting, are provided to the display processor 150,
Which processes the received video signal according to the
picture control setting.
[0044]
Additional adjustable picture control variables can
be provided to the display screen 115, such as an adjustable
intensity variable for the light engines. Light engines of a
CRT display include the electron guns; Whereas, light
engines of an LCD display refer to its backlight source. In
some embodiments, a picture control setting is stored in a
memory 165 and read by the display processor 150 upon
system poWer on. In other embodiments, the display pro
cessing subsystem 110 includes memory for storing the
picture control setting locally. In some embodiments, mul
tiple different picture control settings can be stored in the
memory as selectable presets. For example, a chosen preset
is loaded into the display processor 150 upon user selection.

The on-screen display generator 225 produces an
on-screen display image, sometimes referred to as a com
parison image, including three image cells for the exemplary
group of three different picture control settings. Each cell
includes a representation of the received video image so that
all three cells can be displayed at the same time in the same
on-screen display image. Each image cell is displayed With
the picture tuned according to a respective one of the three
different picture control settings of Table I. Thus, each of the
three image cells includes the same image With varying
degrees of brightness. The video output buffer temporarily
stores the comparison image providing it as an output to the
display processor 150.
[0059] In some embodiments, the picture adjust module
205 receives additional information related to the received
video signal. This additional information can include one or
more of sensor information, as described above, and pro
gram information related to a particular program. For
example, the program information can be received from a
separate program service, such as a TV GUIDE® service or
separate channel providing program-related information.
control settings generator 230 receives program information
and uses it to tailor the different picture control settings
according to the genre of the program. Some examples of
different genre include: movies, sports, concerts, video
games, animation, neWs, historical subject matter, and the
like.
[0063] Upon entering the display-setting mode, the picture
control settings generator 230 uses genre information, When
available, to generate the different picture control settings to
produce enhanced vieWing according to the identi?ed genre.
For example, the picture control settings generator 230
generates picture control settings having enhanced green
colors in response to a sports genre. The same picture control
settings generator 230 generates picture control settings
having enhanced broWn and/or red colors in response to a
historical subject matter genre. In response to an animation
or video game genre, picture control settings generator 230
generates picture control settings having enhanced color
saturation. Other program control settings can be adjusted
independently and in combination, depending upon the one
or more algorithms used in the display-setting mode to
present the end user With enhanced vieWing conditions.
