Image Sensor API: Functions

WiSNAP's Image Sensor API provides the following functions to interface with image sensors.

---

Function: open

Opens a communications session with the image sensor.

Syntax

handle = image_sensor_api(device,'open',port)

Input(s)

device	Image sensor device (string): 'ADCM-1670': Agilent ADCM-1670 camera module. 'ADNS-3060': Agilent ADNS-3060 mouse sensor.
port	Communications port (string).

Output(s)

handle

Device handle (positive integer).

Example(s)

shandle = image_sensor_api('ADCM-1670','open','COM1')

shandle = image_sensor_api('ADNS-3060','open','0378')

---

Function: init

Initializes the image sensor.

Syntax

status = image_sensor_api(device,'init',handle)

Input(s)

device	See function open.
handle	Device handle (positive integer).

Output(s)

status

Success status (-1 = error, +1 = success).

Example(s)

status = image_sensor_api('ADCM-1670','init',shandle)

status = image_sensor_api('ADNS-3060','init',shandle)

---

Function: frame

Captures the current frame from the image sensor.

Syntax

imager = image_sensor_api(device,'frame',handle)

Input(s)

device	See function open.
handle	Device handle (positive integer).

Output(s)

imager

Image array NxM, color depth D (NxMxD matrix).

Example(s)

imager = image_sensor_api('ADCM-1670','frame',shandle)

imager = image_sensor_api('ADNS-3060','frame',shandle)

---

Function: close

Closes the communications session with the image sensor.

Syntax

status = image_sensor_api(device,'close',handle)

Input(s)

device	See function open.
handle	Device handle (positive integer).

Output(s)

status

Success status (-1 = error, +1 = success).

Example(s)

status = image_sensor_api('ADCM-1670','close',shandle)

status = image_sensor_api('ADNS-3060','close',shandle)
