Alexlp: /* Obtaining of static and dynamic images */

{{en|ru=Video_API_Extensions.Ru|cn=Video_API_Extensions.cn}}

Given realization of Video API has a number of opportunities which are absent in standard Axis Video API.

== Extensions enabling ==
By default the Video API extensions are blocked. For unblocking it is necessary to set a corresponding variable:
<nowiki>http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&ElphelExtensions.Enabled=yes</nowiki>

== Obtaining of static and dynamic images ==
The standard interface for the static and dynamic images obtaining in JPEG and MJPG formats is have a few additional parameters.

{| border="0" cellpadding="2"
|-
|e_dcm_hor ||-|| horisontal decimation (resolution/image size reduction)
|-
|e_dcm_vert ||-|| vertical decimation (resolution/image size reduction)
|-
|e_bin_hor ||-|| horizontal binning (sensitivity for lower resolution)
|-
|e_bin_vert ||-|| vertical binning (sensitivity for lower resolution)
|-
|e_woi_width ||-|| sensor active window width (before decimation)
|-
|e_woi_height ||-|| sensor active window height (before decimation)
|-
|e_woi_left ||-|| sensor active window left margin (before decimation)
|-
|e_woi_top ||-|| sensor active window top margin (before decimation)
|-
|e_virt_width ||-|| virtual frame width
|-
|e_virt_height ||-|| virtual frame height
|-
|e_fliph ||-|| flip (mirror) image horizontally (uses in-sensor capabilities)
|-
|e_flipv ||-|| flip (mirror) image vertically (uses in-sensor capabilities)
|-
|e_quality ||-|| JPEG Quality (%)
|-
|}

=== Examples ===
Example of the static image obtaining with using the next parameters:
<nowiki>http://192.168.0.9/axis-cgi/jpg/image.cgi?e_dcm_hor=2&e_dcm_vert=2&e_woi_width=1000&e_woi_height=900&e_woi_left=600</nowiki>

Example of the dynamic image (MPJPG) obtaining with using the next parameters:

<nowiki>http://192.168.0.9/axis-cgi/mjpg/video.cgi?e_dcm_hor=2&e_dcm_vert=2&e_woi_width=1000&e_woi_height=900&e_woi_left=600</nowiki>

You can play this videostream, for example, by using the MPlayer (more detailed description see at [[Using Mplayer With Video API]]):

<nowiki>$mplayer -demuxer lavf "http://192.168.0.9/axis-cgi/mjpg/video.cgi?e_dcm_hor=2&e_dcm_vert=2&e_woi_width=1000&e_woi_height=900&e_woi_left=600&bogus.mjpg"</nowiki>

If any from parameters is not specified, the default values are used. You can find these values at the address:
<nowiki>http://192.168.0.9/axis-cgi/admin/param.cgi?action=list&group=ImageSource.I0.Sensor</nowiki>
'''Note''': All API extensions have the prefix "E_".

You can change the default value by standard way for Axis Video API. For example:
<nowiki>http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&ImageSource.I0.Sensor.E_DcmHor=1</nowiki>

== Obtaining the information about the system condition and default values ==
For obtaining the information about the system condition variable you must use the next path:
<nowiki>http://192.168.0.9/axis-cgi/admin/param.cgi?action=list&group=ImageSource.I0.E_CurrentState</nowiki>

In an addition to the obtaining of the standard "'''rfc'''" format there is the obtaining in XML format also. You must use the '''responseformat''' parameter for it. For example:
<nowiki>http://192.168.0.9/axis-cgi/admin/param.cgi?action=list&group=ImageSource.I0.E_CurrentState&responseformat=xml</nowiki>
'''Note'''. If the responseformat not specified or specified incorrect, will be used the default value of '''"rfc".'''

== Video streaming RTP/MJPG and RTP/Theora ==
The Elphel cameras can transfer the video stream by RTP protocol.
=== RTP/MJPG ===
=== RTP/Theora ===

== Exposure control ==
The Elphel cameras support the standard and advanced exposure control interface. About the standard settings see [[Video_API]]

For autoexposure enabling is necessary to use the following command:

<nowiki>http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&ImageSource.I0.Sensor.Exposure=auto</nowiki>

Enabling the manual control of exposure:
<nowiki>http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&ImageSource.I0.Sensor.Exposure=manual</nowiki>

Obtaining the exposure state:
<nowiki>http://192.168.0.9/axis-cgi/admin/param.cgi?action=list&group=ImageSource.I0.E_CurrentState.E_Exposure</nowiki>

Window settings:
<nowiki>http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&ImageSource.I0.Sensor.E_Exposure.E_WinWidth=30&ImageSource.I0.Sensor.E_Exposure.E_WinHeight=45&ImageSource.I0.Sensor.E_Exposure.E_WinLeft=10&ImageSource.I0.Sensor.E_Exposure.E_WinTop=20</nowiki>

Exposure max.values:
<nowiki>http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&ImageSource.I0.Sensor.E_Exposure.E_Max=3000&ImageSource.I0.Sensor.E_Exposure.E_OverMax=30</nowiki>

Talk:Autoexposure

2005-12-17T13:43:16Z

Alexlp: /* I think "Exposure" parameters in the adminweb.html has a bad name. I propose another name - "Shutter" ( The time an image is exposed). */

== preface ==
As it is not just automatic exposure adjustment but .. (can not find - I already wrote that somewhere)
I suggest making some interpreter of the automatic brightness adjustment scripts - with many adjsutable parameters and image conditions/goals it is probably not possible to have a one-size-fits-all adjustment algorithm.
What syntax to use so it will be intuitive, and easy to interpret?
--[[User:Andrey.filippov|Andrey.filippov]] 00:34, 24 November 2005 (CST)

OK - this can probably be solved in the following way:

# at each given moment only on of the parameters will be adjusted - exposure, gains, "curves" (digital gain) or (later) iris
# some flexibility to define goal function and hysteresis ("don't care" region)
# range parameter is allowed to change before failure is reported
# results are provided to the client javascript that controls the overall process

--[[User:Andrey.filippov|Andrey.filippov]] 00:34, 24 November 2005 (CST)

== Autoexposure working ==

Today I tried the code for the basic autoexposure that Spectr made and it really works - feature long waited by us and our customers.

So now it will be great to see the following follow-up features to be implemented too:

1 - Web interface control for the autoexposure (on/off, parameters, monitoring). Monitoring - it will be useful to have exposure and frame rate status update on the main page (i.e. once a second). Current exposure both as absolute time and a fraction of the frame period (maybe just as bar indicator, not numeric percents). When the streamer is running it is also nice to the it status and frame rate (in percents of the sensor frame rate - to see if any frames are dropped). It also might be as a variable length barm not a number.
2 - Plot histograms into a small (i.e. 256x256) png file in the camera when periodically requested by the web page - watching live histogram (as standard in many cameras now) can be useful not just for the customers, but for developing/testing automatic exposure/gain/iris adjustment algorithms.

--[[User:Andrey.filippov|Andrey.filippov]] 21:27, 29 November 2005 (CST)

== autoexposure, static images and web-scripting ==

How to run autoexposure when php/perl-script get image from camera with some options???

== I think "Exposure" parameters in the adminweb.html has a bad name. I propose another name - "Shutter" ( The time an image is exposed). ==

Alexlp:

'' html=2 gets only sensor parameters or FPGA parameters too? For example, it includes P_CLK_FPGA. Is it a FPGA or Sensor parameter? ''

----

There is no clear separation between the sensor and the FPGA parameters. I.e. in model 313 sensor driver was taking into account FPGA clock frequency while calculating and setting the "virtual frame height" that limits the frame rate. In the 333 it is currently not needed as the compressor is faster than the sensor in all modes, but the new Micron 5MPix sensor is again twice faster than previous ones - in has 96MHz pixel clock ...

Elphel 3x3 cameras have own implementation of [http://www.axis.com Axis] [http://axis.com/techsup/cam_servers/dev/cam_http_api_2.htm Video API version 2.xx].

The HTTP-based video interface provides the functionality for requesting single and multi-part images and for getting and setting internal parameter values. The image and CGI-requests are handled by the built-in Web server in the cameras.

Elphel Axis Video API extension proposes some additional possibility. For example, functionality for requesting RTP MJPEG, HTTP Ogg/Theora or RTP Ogg/Theora video streaming.

Elphel 3x3 cameras have own implementation of [http://www.axis.com Axis] [http://axis.com/techsup/cam_servers/dev/cam_http_api_2.htm Video API version 2.xx].

The HTTP-based video interface provides the functionality for requesting single and multi-part images and for getting and setting internal parameter values. The image and CGI-requests are handled by the built-in Web server in the cameras.

Elphel Axis Video API extension proposes some additional possibility. For example, functionality for requesting RTP MJPEG, HTTP Ogg/Theora or RTP Ogg/Theora video streaming.

'' html=2 gets only sensor parameters or FPGA parameters too? For example, it includes P_CLK_FPGA. Is it a FPGA or Sensor parameter? ''

----

There is no clear separation between the sensor and the FPGA parameters. I.e. in model 313 sensor driver was taking into account FPGA clock frequency while calculating and setting the "virtual frame height" that limits the frame rate. In the 333 it is currently not needed as the compressor is faster than the sensor in all modes, but the new Micron 5MPix sensor is again twice faster than previous ones - in has 96MHz pixel clock ...

'' What difference between binning and decimation? Which of them we can call Resolution? ''
