1. General
The KP-M1A is a black and white camera using the latest high grade CCD having a 2/3-inch image
size.
The KP-M1A features high sensitivity, high resolution and high performance.
The KP-M1A is provided with various functions including the multiple step electronic shutter
function, field-on-demand function, integration mode switching function, HD/VD pulse switching
function and non-interlaced scanning function.
The KP-M1A is most suitable for use with a microscope or an image processing system.
The KP-M1A is compatible with the KP-M2/M3.
KP-M1AN: EIA, KP-M1AP: CCIR
2. Major features
(１)Small size and lightweight
Though the KP-M1A is small in size and light in weight, it offers high performance.
A video signal is obtained only by supplying 12V DC.
(２)High resolution
The latest high grade CCD is used. The horizontal resolution is 570TVL (560TVL CCIR), and
the vertical resolution is 485TVL(575TVL CCIR).
(３)Multiple-step electronic shutter function
The multiple-step electronic shutter function is provided.
The eight-step shutter speeds can be selected from 1/100(1/120 for CCIR) to 1/10000.
(４)Internal or external synchronization, and interlaced or non-interlaced operation
The synchronization system and the scanning system are automatically switched by the kind of
an external sync signal.
(５)Field-on-demand function
The image captured at an optional timing by an external trigger signal can be displayed instantly.
The capture time can be adjusted by an external trigger signal and the shutter.
(６)Frame or field integration mode
As the integration mode can be switched, the image according to applications can be obtained by
combining with the scanning system and the electronic shutter function.

7. External synchronization (2:1 interlaced)
When operating the camera by external drives signals, connect sync drive signals (HD, VD) to the
DC IN/SYNC connector, then the mode is automatically switched from the internal sync mode to the
external sync mode.
!Horizontal and vertical drive signal inputs
HD EIA: f(H) = 15.734 kHz ±1 %
CCIR: f(H) = 15.625 kHz ±1 %
VD EIA: f(V) = 59.94 Hz (f(V) = f(H) ÷262.5)
CCIR: f(V) = 50 Hz (f(V) = f(H) ÷312.5)

8. Field on demand function
The KP-M1A is provided with the Field-on-Demand function to record a picture obtained at an
optional timing by triggering to an image memory, etc. Four modes are switchable by the internal
switch.
1) ONE trigger mode
2) TWO trigger mode
3) Fixed shutter mode: 1/1600s(EIA) / 1/1000s (CCIR)
4) External shutter control mode
Set the electronic shutter to OFF.
(1) Application
This function is effective to shoot moving objects for image processing.
Example: Defect detection of items on belt conveyer

A: Image required for the
pulse
FD
(Fixed shutter)
Reset of sync
signal and start of
shutter
A: Image required for the
pulse
R/R function: The desired image is after one field with respect to the input pulse.
FD function: The desired image is immediately after the input pulse.

KP-M1A - 14 -
8-1 ONE trigger mode
The shutter is started bythe rising edge of the trigger A pulse, and V.SYNC is reset by the falling edge
of the trigger A pulse. (After reset, the first field is delivered)
A shutter time is controlled by the duration when the trigger pulse is high.
Only one field image is delivered by one trigger pulse, and a sync signal lasts till the next pulse.
Trigger pulse
* 5Vp-p +0.5/-1.0Vp-p
* Low period: EIA: 16.7ms or more
CCIR: 20ms or more
* High period: 8us or more

KP-M1A - 15 -
8-2 TWO trigger mode
V.SYNC is reset by the falling edge of the trigger A pulse.
(After reset, the first field is delivered.)
The shutter is started by the rising edge of the trigger B
pulse.
The trigger B pulse is inhibited from the falling edge of the
trigger A pulse to 9 to 12H(EIA) /14 to 17H(CCIR), and a
correct picture is not obtained.
Trigger pulse
* 5Vp-p +0.5/-1.0Vp-p
* Trigger A: Low period: EIA: 63.5us or more
CCIR: 64us or more
High period: EIA: 16.7ms or more
CCIR: 20ms or more
* Trigger B: Low period: Not specified
High period: 8us or more

KP-M1A - 16 -
8-3 Fixed shutter mode: 1/1600s(EIA), 1/1000s(CCIR)
The shutter is started by the falling edge of the trigger A pulse, and at the same time V.SYNC is reset.
(After reset, the first field is delivered.)
In this mode, the shutter speed is fixed to 1/1600s (EIA) / 1/1000s(CCIR). Only one field is delivered
by one trigger pulse, and a sync signal lasts till the next pulse.
Trigger pulse
* 5Vp-p +0.5/-1.0Vp-p
* Low period: EIA: 63.5us or more
CCIR: 64us or more
* High period: EIA: 16.7ms or more
CCIR: 20ms or more

KP-M1A - 17 -
8-4 External shutter control mode
The shutter is started by the rising edge of the trigger B pulse. The shutter is effective only for the next
field of the pulse input. When the trigger B pulse is not supplied the normal exposure results.
The V.SYNC pulse of the camera is not reset.
Trigger pulse
* 5Vp-p +0.5/-1.0Vp-p
* Low period: Not specified
* High period: 8us or more
