可以改变，直接设置即可sensor.set_framesize(sensor.**VGA)

使用同一个sensor设置就行，统一为QQVGA。

没有
不过。。。为什么要有？sensor又不会坏。

改为

import sensor, image, time
from machine import Pin

p0=Pin("P0", Pin.OUT)

import sensor, image
import lcd

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.QQVGA2) # Special 128x160 framesize for LCD Shield.
lcd.init() # Initialize the lcd screen.
#lcd初始化

while(True):
lcd.display(sensor.snapshot()) # Take a picture and display the image.
#将图像显示在lcd中

import sensor, image, time

sensor.reset()                      # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA)   # Set frame size to QVGA (320x240)
sensor.skip_frames(time = 2000)     # Wait for settings take effect.
times = 0
while(True):
    img = sensor.snapshot()
    times += 1
    if times > 100:
        img.save("1.jpeg")
        times = 0

可以手动调节曝光。
