1. General
The KP-M1A is a black and white camera using the late st high grade C CD hav ing a 2/3-inc h image
size.
The KP-M1A features high se nsitivity, 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 scan ni ng f unction.
The KP-M1A is most suitable for use with a microscope or an image processing system.
The KP-M1A is compatib le with the KP-M2/M3.
KP-M1AN: EIA, KP-M1AP: CCIR

2. Major features
(１)Small size and lig ht weight

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 shut t er fu nct i on

The multiple-step e lectr oni c shutter function is provided.
The eight-step shutter speeds c an be selected from 1/100(1/120 for CCIR) to 1/ 10000.

(４)Internal or external synchronization, and interlaced or non-interlaced o perat ion

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 sw itched, the image ac cording t o applic ations ca n be obtain ed by
combining with the scan ning system and the electronic shutter fu nct io n.

Note:
The video signal cannot be fed simultaneously from both the VIDEO OUT connector and t he DC
IN/SYNC connector. If both the outputs are connect ed simultaneously, a proper picture cannot be
obtained.
Supply 12V DC in range between 11 and 13V.

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.

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 effect ive to shoot moving objects for image processing.
Example: Defect dete ct ion of items on belt conveyer
