A color interpolation technique may use a Bayer matrix or pattern. In one embodiment, a color intensity gradient may be calculated between data from a center pixel in the Bayer pattern and the sensor spaced from the center pixel. A minimum and maximum gradient for a plurality of pixels may then be determined. Minimum and maximum intensity values for a group of pixel data values may be determined and these may be averaged to determine a value which may be utilized for interpolation purposes. The technique can use only a simple shift and does not require large dividers.

A still video camera as claimed in claim 10, further comprising protect cancelling means for cancelling the protect signal so as to enable the erasure of the picture. 12. A still video apparatus as claimed in claim 10, wherein the record medium is built in said apparatus. 13. A still video apparatus as claimed in claim 10, wherein the record medium is removably loaded in said apparatus. 14. A still video apparatus as claimed in claim 10, wherein said controlling means inhibits re-recording of a picture image into a portion of the record medium corresponding to a protect signal recorded in the record medium. 15. A still video apparatus as claimed in claim 10, wherein said protect signal recording means records a protect signal when recording of a protect signal is instructed during a predetermined time after counting of time is started in response to starting of recording of a picture image into the record medium. 16. A still video apparatus as claimed in claim 10, further comprising picture image reproducing means, and wherein said protect signal recording means records a protect signal when recording of a protect signal is instructed during a predetermined time after counting of time is started in response to starting of reproduction of a picture image from the record medium by said picture image reproducing means. 17. A still video apparatus as claimed in claim 10, 15 or 16, further comprising selecting means for selecting a protect mode or a non-protect mode, and protect instructing means for instructing recording of a protect signal in response to operation thereof in a protect mode selected by said selecting means. 18. A still video apparatus as claimed in claim 10, wherein a reproduction of a picture image being protected is possible in a condition in which erasure of a picture image is not instructed. 19. A video camera comprising: an image pickup device; a mode definition switch that enables a user to selectively set said camera in a first mode and at least a second mode; a recorder which records a picture image signal obtained by said image pickup device onto a record medium; a manually operable switch; protect signal recording means, operable in response to an operation of said manually operable switch when said camera is in said first mode, for recording into a predetermined portion of the record medium a protect signal to inhibit erasure of a corresponding picture image signal recorded on the record medium; controlling means for inhibiting erasure of a stored picture image signal recorded on said record medium when said stored picture image signal corresponds to a detected, recorded protect signal; reproducing means for reproducing a stored picture image; and an indicator on which information representing whether a picture image reproduced by the reproducing means is inhibited from erasure is indicated when said camera is set in said second mode. 20. A video apparatus comprising: a mode selection switch which sets an operational mode of said apparatus, wherein said operational mode comprises one of at least a protection mode, a reproduction mode and an erase mode; a recorder which records an input picture image signal obtained by an image pickup device onto a record medium; protect signal recording means for recording onto the record medium a protection signal when said apparatus is in said protection mode, wherein each recorded protection signal corresponds to
