摘要： A focus detection device having a pair of light receiving sections (a first and second light receiving sections) which receive subject images observed from different view fields having parallax to accumulate charges is disclosed. The accumulation of the charges in the pair of light receiving sections is ended selectably based on an accumulation level of the charges at one light receiving section and an accumulation levels of the charges at both light receiving sections. Moreover/alternatively, the light receiving section has a plurality of light receiving units, and signals to end the accumulation of the charges at the respective light receiving units are sent to the first and second light receiving sections. In this case, a combination of the light receiving unit of the first light receiving section and the light receiving unit of the second light receiving section to which the signals are to be sent can be switched.

摘要： A period extracting section extracts a specific period in a dot code in an image signal corresponding to the dot code, and this specific period is supplied field by field to a maximum value detection section and a minimum value detection section via a detection gate. A threshold value detection section computes the binary threshold value from the detected field-by-field maximum value and minimum value, and holds it in a data holding section. A comparator compares the held threshold value with an image signal with the dot period emphasized by a signal processor to thereby binarize the image signal corresponding to the dot code.
