Abstract: PURPOSE:To properly correct the density of picture by using an output signal of an image sensor corresponding to part of a picture so as to set a binarization threshold level, binarizing other part of the picture, counting black level number of the output signal and comparing it with a prescribed value. CONSTITUTION:A signal read by an image sensor 16 synchronously with a clock signal CLK is subjected to A/D conversion 17 and inputted to a switch 18. The switch 18 is connected to the position A by a command of a CPU 20 and a miximum value is obtained by a detection circuit 22 and a miximum value is obtained by a detection circuit 21 at every output of each line of the image sensor 16, they are inputted to the CPU 20 to form a histogram. The threshold level to be subjected to binarization of the output of the image sensor 16 is set from the histogram. Then the switch 18 is thrown to the position B, the digital signal from the switch 18 and the threshold level from the CPU 20 are compared (19) and subjected to binarization to output a signal BS. The black level number of the signal BS is counted and when the number is at the outside of a prescribed range, the copy density correction signal is corrected. Thus, the proper density is obtained.

Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain a stable video level by making an iris control and a gradation correction control operate so as to have a relation in the image pickup device provided with iris control and gradation correction control functions. SOLUTION: A microcomputer 109 receives a luminance mean value for each of pluralities of image blocks from a detection means 106 and applies weighting to the mean value so as to control the iris in a way that the weighted mean value is coincident with an object value. Furthermore, the microcomputer 109 receives histogram information of the image from a detection means 107 to calculate a gradation characteristics. On the other hand, a means that monitors and discriminates an operating state of the iris interrupts signal processing for gradation correction control during the signal processing operation for the iris control, and starts signal processing for new gradation correction control with signal processing end information for the iris control.  Moreover, when an object is changed during the signal processing for the gradation correction control, the signal processing for the iris control is started and highest priority is placed on it and updating of the gradation characteristics is temporarily stopped to attain stable video level control.
