摘要： PURPOSE: To prevent deterioration in the S/N of a video signal by controlling a shutter speed in response to a zoom position so as to enhance the resolution at the zoom position of the wideangle position where after-image is reduced. CONSTITUTION: Zoom position information 115 detected by a zoom position detector in linking with a zoom lens is inputted to a shutter speed control circuit 105. A selector switch 203 of the control circuit 105 selects a shutter setting signal 210 (211) set by a low speed shutter setting circuit 201 (high speed shutter setting circuit 202) depending on a case of a zoom set at a wide angle position (telescopic position) respectively and gives a signal 114 to the image pickup element. Thus, the after-image is small when the zooming is set at the wide angle position, and in the case where the deterioration in the resolution is less even when the shutter speed is not high, a low speed is selected for the shutter speed, then the bright video image without deterioration in the S/N can be obtained.

摘要： PURPOSE:To enable stable focusing with high accuracy by using a mean level of a signal obtained through M-times sampling of noise for an N period width, thereby performing focusing control. CONSTITUTION:When N-periods of noise X1 is set within M periods of a sampling pulse, that is, within MTs, the relation represented by equation I is obtained, where Ts is a period of the sampling pulse and Tn is a period of the noise X1. In this case, the equation I represents M times sampling of the noise X1 by N periods. Thus, letting the sampling pulse width ts, then when the ts is set according to equation II or set twice the value of the equation II, one period of the noise X1 by M sets of sampling is just sampled without missing. Thus, the periodic component of the periodic noise X1 is completely eliminated by averaging the M sets of sampling values obtained by performing sampling to satisfy the equations I, II.

摘要： PROBLEM TO BE SOLVED: To properly correct a deviated white balance even when an object almost sharing the entire photographed image is a white object or an object of a light source.
SOLUTION: A signal processing circuit 5 receiving an image signal detects information A representative of deviation in white balance (WB) in addition to processing such as production of a luminance signal and a chrominance signal, gives the information A to a WB control circuit 8, which generates a WB control signal. Meanwhile, a zoom magnification E from a zoom value detection circuit 12 and an object luminance F from an object lightness detection circuit 13 are fed to an object distance threshold value setting circuit 10, which produces an object distance threshold value G in response to the zoom magnification and the object illuminance. A WB control variable adjustment value setting circuit 9 uses the object distance threshold value G and an object distance detected value D from an object distance detection circuit 11 to generate a WB control variable adjustment value C and gives it to the WB control circuit 8 for adjustment of the WB control signal. The adjusted WB control signal is used to correct the deviation in the WB.
