Photoelectric conversion elements of line sensors (CIS22 to CIS26) arranged in a zigzag manner read a white reference plate to acquire a white reference read value A, and a white reference read average value AA is determined from the white reference read value A for each line sensor. Further, the photoelectric conversion elements read another white reference plate placed on a document support plate to acquire a white reference read value B, and a white reference read average value BB is determined from the white reference read value B for each of the line sensors (CIS22 to CIS26). By using the white reference read average values AA and BB, a sensitivity effect coefficient C used for uniforming the sensitivities different because of the variation of the distances from the line sensors (CIS22 to CIS26) to the document support plate is determined by dividing the average value BB by a data processing section for each of the photoelectric conversion element of the line sensors. By using a white reference read value Aa acquired by reading a white reference plate immediately before reading a document and a black reference read value, a white reference read value Aa for shading correction for correcting a document read value E is corrected with the sensitivity offset coefficient C. In this way, irrespective of the variation of the distances from the line sensors to the document support plate, the variation of the document read values read from the photoelectric conversion element of the line sensors can be suppressed.

In a flash device arranged to determine the aperture value of a photo-taking lens according to the measured level of a reflection light obtained by preliminary flashing and to control main flashing according to a light control level corresponding to the aperture value, when a light diffusing panel is arranged in front of a main flashing part for a wider flash illuminating angle, another light diffusing panel which gives an equal light reducing effect is also arranged for a preliminary flashing part. The light quantity of preliminary flashing is thus reduced in proportion to the degree of reduction in the light quantity of main flashing, so that the aperture value set by preliminary flashing and the light controllable range of main flashing for photographing can be made to be always in agreement with each other.
