As of ESP-IDF V6, this item has been moved to Component config > ESP-STDOUT.

To begin with, why not try stopping the downscaling from 320x240 to 240x180?

I haven't used `esp_lcd_panel_draw_bitmap` myself, but I believe the following code will correctly display a specific part of the camera image.

while (1) {
camera_fb_t *fb = esp_camera_fb_get();

Is there a possibility that R and B are swapped?


uint32_t r = ((p0 >> 11) & 0x1F) + ((p1 >> 11) & 0x1F)
+ ((p2 >> 11) & 0x1F) + ((p3 >> 11) & 0x1F);
uint32_t g = ((p0 >> 5) & 0x3F) + ((p1 >> 5) & 0x3F)
+ ((p2 >> 5) & 0x3F) + ((p3 >> 5) & 0x3F);
uint32_t bl = (p0 & 0x1F) + (p1 & 0x1F)
+ (p2 ...
