Python+OpenCVでのチェック、Pythonシート検査設定用プログラムの解像度を3264x2448に変更したものを作成して動作させてみたが、どうもおかしい。
トリミング位置の赤線表示の右側と下側が切れてしまう。
解像度を3264x2448に設定できていないと思い、次の様なプログラムを作成し、設定確認できるようにした。（確認中はいろいろいじってる。）

出力された数値の意味がわからないんだが、とりあえず全て表示するコード。
結果は次の通り。
width = 2048
height = 1536
FPS = 3
FOURCC = 22.0
FOURCC = 22.0
22.0
FPS = 3
FOURCC = 22.0
22.0
FPS = 3
FORMAT = -1
MODE = 1
CV_RGB = 1
BRIGHT = 0
CONTRAST= 32
SATURAT = 32
HUE = 0
GAIN = -1
EXPOSURE= -5
WB_TEMP = -1
GAMMA = 150
FOCUS = 0
PAN = -1
TILT = -1
ROLL = -1
IRIS = -1
AUTO_EXP= 0
AUTO_FCS= 0
AUTO_WB = -1
XIAUTOWB= -1
XI_AEAG = -1
XIAEMXLT= -1
XIAGMXLT= -1
TEMPERAT= 4600
TRIGGER = 1
TRIGGERD= 1
SETTINGS= 1
解像度が2048x1536になっている。
2592x1944に設定しようとしても、2048x1536になる。
FOURCCは22.0で、変更しようとしても変更が効いていないのか22.0のままで変化無し。
しばらく格闘しても訳が分からないので、オートフォーカスを切り、マニュアルフォーカス操作をやってみることにする。
