怎么能减小灰度图与彩图之间的切换频率？

[惠斯]

import sensor, image, math,pyb

sensor.reset()
sensor.set_framesize(sensor.QVGA)
while(True):
sensor.set_pixformat(sensor.GRAYSCALE)
for i in range(10):
img=sensor.snapshot()
for j in range(100):
x=(pyb.rng()%(2img.width()))-(img.width()//2)
y=(pyb.rng()%(2img.height()))-(img.height()//2)
img.set_pixel(x,y,255)
sensor.set_pixformat(sensor.RGB565)
for i in range(10):
img=sensor.snapshot()
for j in range(100):
x=(pyb.rng()%(2img.width()))-(img.width()//2)
y=(pyb.rng()%(2img.height()))-(img.height()//2)
img.set_pixel(255,255,255)

不更改sensor，直接把彩色的图片转为灰度图。

@kidswong999 怎么还是不能把彩图转变成灰度图啊

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.
clock = time.clock()                # Create a clock object to track the FPS.

while(True):
    clock.tick()                    # Update the FPS clock.
    img = sensor.snapshot()
    # img这里是彩色
    img = img.to_grayscale()
    # img这里是灰色
    print(clock.fps())
