embodiment 1
[0038]FIGS. 1 to 12 indicate Embodiment 1 of the present invention, and FIG. 1 is a block diagram illustrating a configuration of an image pickup apparatus. Note that, although FIG. 1 indicates an example in which the image pickup apparatus is configured, for example, as a digital camera, the image pickup apparatus is not limited to a digital camera, and may be applied widely to any of various types of apparatus having a shooting function such as a digital video camera and a telephone apparatus with a shooting function.
[0039]As illustrated in FIG. 1, the image pickup apparatus includes a lens 1, an image pickup device 2, an image processing section 3, an AF (automatic focus) evaluation value arithmetic operation section 4, a display section 5, a camera-shake detection section 7, an image stabilization section 8, an exposure control section 9, a focus control section 10, a camera operation section 11 and a camera control section 12. Here, although a memory card 6 is illustrated in FI...
example 1
[0136]An average of three pixels where pixel values of the three pixels are 389, 254 and 162 is calculated as follows.
Three pixel average=(389+254+162)×1365 / 4096=805×0.333252=268
example 2
[0137]An average of four pixels where pixel values of the four pixels are 389, 254, 162 and 92 is calculated as follows.
Four pixel average=(389+254+162+92)×1024 / 4096=897×0.25=224
